The CCSDS space packets may be of variable length or fixed size at the discretion of the user and may be submitted for transmission at variable intervals. The SIST EN 16603-50-53:2015

4.3 Services
The CCSDS Space Packet Transfer Protocol provides users with data transfer services. The point at which a service is provided by a protocol entity to a user is called a Service Access Point. A Service Access Point of the Space Packet Transfer Protocol is identified by a SpaceWire address and each service user is also identified by a SpaceWire Address.
Service data units submitted to a Service Access Point are processed in the order of submission.
Implementations may be required to perform flow control at a Service Access Point between the service user and the service provider. However, this standard does not recommend a scheme for flow control between the user and the provider.
