    Abstract: Intersection signaling method for bearer management in a communication network with transporting bearer resource request message of both the UE and RN via Base station to managing entity of RN within EPC, as a signaling message over uplink channel referred to as ‘Union of Resource Request (UR 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 signaling message to Evolved Packet Edge (EPE) via Base station over the downlink channel referred to as ‘Intersection of Admission Response (IA Response)’. This manages bearer setup signaling as a single loop, by transportation of ‘UR Request’ signaling message and receiving one “IA Response” signaling message over uplink and downlink channels respectively. EPE is a conglomeration of network nodes.

  • Publication number: 20130259051
    Abstract: The invention relates to a learning-based method for loop avoidance in a packet switched communication network. In one embodiment, this is accomplished by configuring each communication device to maintain a table of unique identifiers, where the unique identifiers include Media Access Control (MAC) address, MAC and Virtual Local Area Network (VLAN) address, Internet Protocol (IP) address or any other unique device identifier, receiving one or more data packet on one or more port of the device, checking the table for unique source identifier of the received data packet, determining whether the received data packet is received from the same port of the device as in the table against the corresponding entry, and updating learned time entry with current system clock time of the device and forwarding the data packet to the next communication device if the packet is received from the same port.

  • Patent number: 8391180
    Abstract: The present invention provides a novel method for hierarchy of preplanned protected path for both node and link failure in the realm of Carrier Ethernet Technology. In the event of failure in a hierarchy, the traffic is switched from work (primary) path to protected (secondary) path. If such path does not exist within a given hierarchy then traffic is routed through multiple hierarchies until SLA is met or no path exists. Hierarchies make the network fault resilient.
