Providing end-to-end connectivity with QoS guarantees in integrated wireless/wired networks

Wireless and wired networks have commonly evolved separately. However with the integration of quad-play services (i.e., mobile/fixed voice, video, and data) into a single network infrastructure the provisioning of end-to-end connections spanning both the wireless and the wired domains becomes an important issue. In this paper two solutions are proposed for implementing an integrated end-to-end signaling for establishing QoS-guaranteed connections in integrated WiMAX and MPLS based networks. The two solutions are based on the integration of WiMAX management messages and RSVP-TE signaling. Their main difference consists in the way flow WiMAX message and RSVPTE signaling are triggered and coordinated.
