Abstract: A method and system of bearer management signalling in a communication network comprising of transporting bearer resource request message of both the UE and RN via DeNB to managing entity of UE within EPC, as a signalling message over uplink channel referred to as ‘Union of Resource Request’ message. The bearer resource response message from one of the managing entity of UE or managing entities of UE and RN within EPC are transported as a signalling message to Evolved Packet Edge (EPE) via DeNB over the downlink channel referred to as ‘Union of Admission Response’. This manages bearer setup signalling as a single loop, by transportation of ‘UR Request’ signalling message and receiving one ‘UA Response’ signalling message over uplink and downlink channels respectively.

Abstract: The present disclosure relates to managing a logical topology change in a network. The entries of the forwarding database are flushed intelligently without arbitrarily removing the forwarding database resulting in flooding. In one embodiment, a logical topology number (LTN) is maintained by all the interfaces and the forwarding database in the logical topology. In case of any change in the network topology, the LTN of the interfaces affected by the topology change is changed. Further, while sending a frame, LTN of the forwarding database entry for a destination address is compared with LTN of the logical topology. In case of mismatch, the entry is invalidated and the frame is flooded to all other ports for entering new entries into the database. LTN of the forwarding database entry for a source address is compared with the LTN of the logical topology.
