Abstract
A system and method for implementing a Quality of Service (QoS) fallback using Resource Reservation Protocol (RSVP) includes initiating a communication session with a QoS precondition between a first domain and a second domain. It is determined whether the second domain supports the QoS precondition. Intra-domain RSVP is established in the first domain if the second domain does not support the QoS precondition.

A method for implementing a Quality of Service (QoS) failback using Resource Reservation Protocol (RSVP), comprising:
- initiating a communication session with a QoS precondition between a first domain and a second domain;
- determining whether the second domain supports the QoS precondition;
- establishing intra-domain RSVP in the first domain if the second domain does not support the QoS precondition and end-to-end RSVP is not available;
- retrying the communication session with the second domain without the QoS precondition;
- and
- facilitating communication between the first domain and the second domain using the intra-domain RSVP in the first domain.
A system for implementing a Quality of Service (QoS) fallback using Resource Reservation Protocol (RSVP), comprising:
- an endpoint in a first domain operable to initiate a communication session with a QoS precondition between the first domain and a second domain;
- a call manager in the first domain coupled to the endpoint, the call manager operable to:
- determine whether the second domain supports the QoS precondition;
- and
- establish intra-domain RSVP in the first domain if the second domain does not support the QoS precondition and end-to-end RSVP is not available;
- retry the communication session with the second domain without the QoS precondition;
- and
- facilitate communication between the first domain and the second domain using the intra-domain RSVP in the first domain;
- and
- one or more RSVP agents in the first domain coupled to the call manager, the RSVP agents operable to facilitate the intra-domain RSVP in the first domain.
A system for implementing a Quality of Service (QoS) failback using Resource Reservation Protocol (RSVP), comprising:
- means for initiating a communication session with a QoS precondition between a first domain and a second domain;
- means for determining whether the second domain supports the QoS precondition;
- means for establishing intra-domain RSVP in the first domain if the second domain does not support the QoS precondition and end-to-end RSVP is not available;
- means for retrying the communication session with the second domain without the QoS precondition;
- and
- means for facilitating communication between the first domain and the second domain using the intra-domain RSVP in the first domain.
