METHODS, ARCHITECTURES, APPARATUSES AND SYSTEMS FOR ENABLING WIRELESS RELIABILITY AND AVAILABILITY IN MULTI-DOMAIN DEPLOYMENTS

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products directed to enabling wireless reliability and availability in multi-domain deployments are described herein. In an embodiment, a network element may be configured to send, to a first network element of a first domain network, a first request message requesting one or more tracks towards a second domain network, the first request message indicating a requested quality of service (QoS). The network element may be configured to receive, from the first network element, a response message indicating (i) one or more second network elements of the second domain network interconnecting the first domain network with the second domain network, and (ii) a QoS partitioning of the requested QoS to be applied on the first and the second domain networks.
