Operational Needs
ASM Support Systems facilitate the exchange of pre-tactical and tactical ASM data between ASM Support Systems and External Users. This information exchange supports the optimisation of ASM operations from the beginning of the airspace planning cycle. Furthermore, a national ASM Support System will allow the creation of bookings in airspace structures managed by another national ASM Support System, according to the procedures defined in ERNIP Part 3 ASM Handbook and bilateral agreements between States.
General description
The ASM Service is designed to support data exchange between ASM Support Systems and External Users both within and across FAB boundaries.
ASM Support System - External User
In this configuration the ASM Support Systems can each act as a client to each other, though the relationship does not need to be bidirectional. This allows each ASM Support System privilege to distribute general information from the other system to its users. It also allows each ASM Support System to request and modify bookings in the other system and engage in coordination with the other system directly. It is the responsibility of the system providing the services to restrict the data shared with all or each client as appropriate. Equally, it is the responsibility of the client system to ensure booking, creation and editing is granted for the appropriate individual users.
In the case when the External User is an ATC system, the ASM system acts as the provider while the ATC system acts as the consumer. However, the consumer can notify that it has received activation data.
Obtaining up to date data
The interfaces defined within this document are supported by both a Synchronous Request/Reply mechanism and a Publish/Subscribe Push mechanism.
-
Publish/Subscribe Push
The Publish/Subscribe Push mechanism allows a client to subscribe to a topic and receive messages published on that topic. The Publish/Subscribe mechanism is supported by two procedures:
- subscription management: the client creates a new subscription and, in general, a corresponding message queue is allocated to collect messages related to the requested subscription topic. (see SubscriptionManagement interface)
- message consumption: the client consumes the messages from the message queue for the subscription topic. (see Publication interface)
The Publish/Subscribe mechanism is implemented using AMQP to support coordination between ASM Support Systems and External User to exchange the near real-time updates of their ASM data.
-
Request/Reply
The Synchronous Request/Reply mechanism allows a client to request and to receive ASM data. It is used to retrieve the current ASM data of the other system either on the initial connection between ASM Support Systems and External Users or to re-establish synchronisation potentially after one has experienced downtime or due to network failures.
This Request/Reply mechanism may also be implemented by clients that are interested in a small subset of the ASM service where the data is subject to change infrequently or when using latest data is not crucial.
As two ASM Support Systems may not be fully synchronised all of the time, Request/Reply mechanism is implemented to re-establish synchronisation by exchanging the latest snapshot of the available ASM data. The systems are synchronised again and they can continue to be updated by using the Publish/Subscribe mechanism.
-
Filtering
To avoid unnecessary processing of irrelevant messages on the client side some message filtering functionalities have to be implemented by both Request/Reply and Publish/Subscribe mechanisms through a combination of the following filter criteria for each ASM Service Interface:
- Activity,
- Airspace,
- Airspace Name,
- Airspace Feature Type,
- Change Period,
- Geometry,
- Interested Interval,
- Mission.
When using the Publish/Subscribe mechanism, the External User has to set the required message filtering criteria when creating the subscription so that the messages for each type of subscriptions can be filtered before they are published to the message queues allocated to that External User.
The Request/Reply mechanism requires the External Users to set the required message filtering criteria when generating the request.
To allow ASM data requests to be aligned with subscriptions a single abstract Filter definition is available for use by both mechanisms, in that the SubscriptionCreationRequest message is an extension to the basic FilteredRequest message as shown in the diagram below. Consequently, the same Filters can be used when requesting ASM data and subscribing for ASM data to ensure the same data is retrieved via both mechanisms. Specific filter implementations that have been deemed necessary for the services to be usable are defined in the specification document. The available filters may be extended beyond those specified in any implementation of this service. This allows for custom filtering to be defined by a provider of this service while still conforming to the interfaces defined in the specification document. It has to be noted that only the filters defined in the specification document are to be relied upon in order to create an implementation independent client.
The FilteredRequest is used throughout the service interfaces and is extended to form the SubscriptionCreationRequest. The FilteredRequest defines a series of Filters which will be applied using the logical OR operator. Filters may be combined with a logical “AND” using the “AndFilter”.
In the specification document, each service interface defines in detail the Filters it accepts.
ASM-INTF-FIL-010: All ASM service interfaces specified in this document shall implement a filtering functionality both for Synchronous Request/Reply and Publish/Subscribe Push application message exchange patterns.

Access and Use
Quality of Service
There are a number of non-functional requirements which need to be taken into account when considering the exchange of ASM data, as they are relevant to any system development. These type of requirements typically are concerned with characteristics such as availability and performance, and can be used as measurements of a system’s efficiency, effectiveness and continued viability when comparing actual performance with expected performance.
In order for these non-functional requirements to be defined as concrete testable requirements, significant analysis of the entire environment would need to be carried out to ascertain the basic nature of the infrastructure and the predicted user activity.
The definition of these non-functional requirements is out of scope of this document.
A non-exhaustive list of some of the features which might directly influence the non-functional aspects is given below.
· Predicted load (typical and extreme)
· Number of concurrent users (typical and extreme)
· Available network bandwidth
· Hardware specifications
· Security policy restrictions
Some of the associated non-functional requirements which need to consequently be considered are described in the following section.
The reliability of the service is how it performs its functions under specified conditions for a specified period of time. Two main requirements should be agreed between all interested parties: availability and recoverability.
The expected availability of the service is the degree to which it is operational and accessible when required for use. Whilst the ideal goal is a consistent 24/7/365 service provision, this is not always a realistic target due to the potential need for disaster recovery, maintenance or upgrades. As well as agreeing on the acceptable levels of (non)availability, contingency plans need also to be agreed in order that operations can continue seamlessly and safely when any downtime is required.
Recoverability concerns how the service is re-established in the event of an interruption or a failure.
Monitoring and measuring these characteristics provides a means to identify where improvements are required in terms of reliability.
The performance efficiency of the service is key to assessing the quality of the service. Performance requirements to be agreed between all interested parties cover the capacity of the service and its response times.
The capacity of the service, i.e. the expected maximum rate at which the service can process transactions and the maximum message size of responses must be specified. The requirement can include the number of items that can be stored, the number of concurrent users, the communication bandwidth, throughput of transactions, and size of messages.
The expected time bahaviour of the service, i.e. the processing/response time, must be specified. This can be expressed as an indication of a maximum time needed for the service provider to complete the request, measured from the time instant the service provider receives the request to the time instant the service provider sends the response or makes it available.
Information being managed within an ASM Support System is highly sensitive and is to be managed with utmost care in terms of security.
The expected security mechanisms should be agreed between all interested parties. Requirements should be expressed for confidentiality and integrity.
Confidentiality ensures that information is accessible only to those authorized to have access. Integrity is an assurance that unauthorized access to, or modification of, an information service interface or information is prevented.
Mechanisms and strategies for achieving confidentiality and ensuring integrity are numerous and various in nature. Whilst considering how best to achieve maximum levels of security, it is important also to consider that technology choices will not be so bespoke or idiosyncratic that they prevent potential future users from taking up the system.
The ASM Support System is extensible. This means that new features can be added. This places requirements on the design. It must be adaptable over time and remain interoperable between two major versions. Incompatibility between software versions is inevitable as systems mature and improve over their lifetime, but it is a priority to minimise disruption between upgrades. Maintaining a stable interface between two major versions would allow the wider user community the opportunity to upgrade their software at the most suitable time, rather than enforcing the need for updating as soon as a new release becomes available

Interfaces
Interface role
The Subscription Management interface allows the management of subscriptions to the other services by External Users. External Users are able to receive the information of their interest generated by the ASM Support Systems and provided via the interfaces. Each interface applies filtering options in order to ensure data provision aligned with the requirements of the External User.
The interface allows for the creation and deletion of subscriptions to consume data from all other ASM service interfaces. A client may create a subscription to a single topic with each request but only one subscription per topic may be created at a time. In response the client will receive the name of an AMQP message queue. The name can then be supplied when creating subscriptions for additional topics to use the same queue. The client can consume the messages from the queue with the given name.
Figure 7 in Section 2.4.2.1 provides an overview of the Subscription Management interface
The elements in the data model are described in full detail in section 2.7.4.
Information Exchange Flow
The diagram in Section 2.4.2.2 presents the information exchange flow for the Subscription Management interface.
Interface Functions
The Service interface performs the following functions:
o Creating a Subscription introduces a new Subscription into the ASM Support System.
o Starting a Subscription starts an existing Subscription in the ASM Support System.
o Stopping a Subscription stops an existing Subscription in the ASM Support System.
o Deleting a Subscription allows for deletion of an existing Subscription.
o Listing existing Subscriptions provides access to existing Subscriptions in the ASM Support System for the External User.
ASM-INTF-SUBS-010: ASM Service shall be supported by the Subscription Management interface to manage the subscriptions
ASM-INTF-SUBS-020: The Subscription Management interface shall support the following operations:
o createSubscription,
o startSubscription,
o stopSubscription,
o deleteSubscription,
o listSubscriptions.
Operations
This operation is intended to create a subscription in the ASM Support System in response to a request from an External User. As a result, a subscription is either created in the local ASM Support System and the External User is notified, or a subscription is not created and an appropriate error message is transmitted to the External User.
It is down to the implementation as to whether or not subscriptions need to be remade at any other subsequent connection.
Associated messages
ASM-INTF-SUBS-030: The createSubscription operation shall receive and process the SubscriptionCreationRequest message from an External User.
ASM-INTF-SUBS-040: If no queue name is provided in the SubscriptionCreationRequest message the service shall assign a queue name to the External User subscription.
ASM-INTF-SUBS-050: If an active queue name is provided in the SubscriptionCreationRequest message the service shall reuse this queue name for the External User subscription.
Note: The queue name allows for connection to an Advanced Message Queuing Protocol (AMQP) message queue.
ASM-INTF-SUBS-070: The service shall apply the filters defined in the SubscriptionCreationRequest to all data notified via the AMQP message queue.
ASM-INTF-SUBS-080: The createSubscription operation shall validate the SubscriptionCreationRequest message against the following criteria which must be met:
o All mandatory data for SubscriptionCreationRequest message are provided
o The requestor does not have an existing PAUSED or ACTIVE subscription for the same topic.
o If a queue name is set in the SubscriptionCreationRequest message it must match an existing queue name belonging to the requestor.
o The filters provided in the SubscriptionCreationRequest message must be applicable to the topic being subscribed for. Acceptable filters are defined by the query operation in this document that maps to the subscription topic.
ASM-INTF-SUBS-090: If the subscription request is valid, the createSubscription operation shall transmit the details of the newly created subscription, including the name of the AMQP queue to be used, in the SubscriptionCreationReply message to the requesting External User.
ASM-INTF-SUBS-100: The subscription shall always be created in the ‘PAUSED’ state.
ASM-INTF-SUBS-110: If the request or the resulting subscription is not valid, the createSubscription operation shall transmit an appropriate error in the SubscriptionCreationReply message to the requesting External User.
ASM-INTF-SUBS-115: The service provider should define a TTL (Time-To-Live) for messages of each subscription topic.

Interface role
The Publication interface enables the management of updates based on subscriptions by External Users. External Users are able to receive notifications of updates of the information of their interest generated by the ASM Support Systems. Each interface applies filtering options in order to ensure data provision aligned with the requirements of the External User.
This interface publishes the data that would otherwise be directly requested from other interfaces. As such the data coming via this interface is contained within the notification messages defined in section 2.7.3 Interface Messages and containing data items described by each of the other interfaces. As a result, this interface does not define its own data model.
Information Exchange Flow
The following diagram presents the information exchange flow for the Publication interface. The diagram shows a change occurring within the ASM Support System, the changed data being passed to the Publication interface which applies the filters related to each subscription and the relevant data being published to subscribed consumers.

Behaviour
Interface role
The Long Term Planning interface allows for the creation, modification and retrieval of long term planning data held within the ASM Support System. It is not foreseen that one ASM Support System may create long term planning in another ASM Support System and so the creation and update mechanisms may be limited to External Users acting as a user of the ASM Support System under the External ASM User - ASM Support System use of the service case.
Figure 14 in Section 2.4.4.1 provides an overview of the Long Term Planning interface
Information Exchange Flow
Figure 15 in Section 2.4.4.2 depicts the information exchange flow for the Long Term Planning interface.
Interface Functions
The interface performs the following functions:
- Creating an Event - introduces a new Event into the ASM Support System
- Updating an Event - updates an existing Event in the ASM Support System
- Requesting a List of Events - allows access to the Event information from within the ASM Support System
ASM-INTF-LTPL-010: ASM Service should be supported by the Long Term Planning interface to manage the events.
ASM-INTF-LTPL-020: The Long Term Planning interface shall support the following operations:
- createEvent,
- updateEvent,

Interface role
The Local Airspace Structure interface allows for retrieval of airspace structures and activity data from within the ASM Support System by External Users.
Local ASM Support Systems maintain a local data base that contains national airspace structures. The interface allows External Users to obtain the definitions of the airspace structures, provided by the providing system in accordance with the provider requirements, as well as activity data, in order to follow their status and the reservations associated to them.
Figure 17 in Section 2.4.5.1 provides an overview of the Local Airspace Structure interface
The elements in the data model are described in full detail in section 2.7.3 Interface Messages.

Interface Binding Description Overview
N/A
Behaviour
Interface role
Booking is an interface that enables the creation, modification and retrieval of bookings, including details of conflicts between different bookings within the ASM Support System by External Users. The interface allows for continuous updates in real time of Booking information among authorised ASM Support Systems/External Users in order to enhance cross border coordination based on the most recent information.
The interface also enables booking of airspace structures across national borders; airspace users are able to book foreign airspace using their local ASM Support System. The process of a foreign booking follows the ASM process defined in dedicated LoAs between States.
The creation and modification of bookings is supported through the provision of ‘Actions’ by the interface. The Actions describe the allowed modifications that a user may take on a specific booking. Actions are subject to change based on the state of a booking and the current time.
Figure 20 in Section 2.4.6.1 provides an overview of the Booking interface
Information Exchange Flow
Figure 21 in Section 2.4.6.2 depicts the Booking interface information exchange flow
Interface Functions
The interface performs the following functions:
- Creating a Booking introduces a new Booking into the ASM Support System to be approved to be incorporated into the plan.
- Updating a Booking updates an existing Booking in the ASM Support System potentially as a result of a CDM process or simply to update the plan to reflect changes to planned activities.
- Requesting Booking List allows access to the Booking information from within the ASM Support System to allow for CDM processes.
- Requesting Actions allows access to the Actions that can performed by the actor. Identifying where they may contribute to the CDM process within the ASM Support System and which Airspace Reservation they can update to better inform the plan.
- Requesting History allows access to the history of all actions that have been performed on a Booking.

Interface role
The Airspace Status interface enables External Users (service consumers) to retrieve activation data on the status of airspace in the ASM system in real time.
An activation refers to the specific state of an airspace structure at the current time and until a specified end time. The end time of an activation is subject to change, it may be shortened or extended.
This interface allows consumers to see in real time the status of the airspace managed by the ASM Support System. The activation data provided contains the information known by the ASM system including the start time of the current activation state and the expected end time. Within the ASM system, the actual end time may be changed during the tactical phase. The changes to the current activation state are communicated immediately. The current activation state can be supplemented with the planned airspace usage information available from the Booking Interface in section 2.4.6, thus allowing visibility of the latest planned upcoming activations and deactivations within the ASM system.
This interface is treated as safety critical when used via the publish-subscribe mechanism detailed in the Publication Interface section 2.4.3. Under such use it requires that the External User acknowledges receipt and understanding of the activation data allowing the ASM system to detect in cases that a change in status is not received and processed by the External User. In contrast to the other interfaces defined in this service, subscribing to activation data will cause the current activation state to be automatically fully published to the subscriber. This ensures the initial state is always transmitted to External Users subscribing to activation data and also ensures that the initial state is acknowledged.
Figure 32 in Section 2.4.10.1 provides an overview of the Airspace status interface.
