REAL-TIME SESSIONS QUALITY-OF-SERVICE OVER RESERVATION-BASED ACCESS

摘要

A collection of methods, which when combined together provide suitable bandwidth resources for real-time content exchange over a satellite-based network, wherein the network employs a reservation-based access scheme, such as but not limited to DVB-RCS. Furthermore, the methods provide suitable bandwidth wherein transmission conditions deteriorate while real-time content is being exchanged and the already allocated resources can no longer be used.

主权项

1. A method, comprising:
detecting at a terminal of a satellite communication network one or more jitter-sensitive applications; sending from the terminal to a hub of the satellite communication network a request for establishing one or more connections between the terminal and the hub, or between the terminal and a second terminal using mesh connectivity; receiving at the terminal from the hub a response to said request for establishment of said one or more connections, wherein said response corresponds to whether sufficient bandwidth capacity having allowable jitter has been allocated to the one or more jitter sensitive applications; and applying admission control to one or more applications based on whether sufficient bandwidth having the allowable jitter has been allocated, wherein upon receiving a response acknowledging establishment of said one or more connections the method further comprises:
determining for each established connection a network-unique identifier included in connection establishment signaling;determining that a received allocation table includes allocations for said one or more connections in accordance with said one or more network-unique identifiers; andscheduling content of an applicable session to be transmitted on applicable allocations.
