Pinning the route of ip bearer flows in a next generation network

摘要: Methods and systems for extending the IMS/SIP architecture of NGN to provide QoS service generic bearer flows. More particularly, a method is provided establishing an end-to-end path communication session in multi-domain network which out band signalling protocol used establish communications sessions. The comprises receiving out-of-band message including information representative at least opposite end point first segment path. define cross-connect mapping through node between respective local endpoints second hosted by node. Information then inserted into message, forwarded.
