Publication number: 20180183708Abstract: The present disclosure generally relates to packet processing by a network element system that transfers first and second packet flows of the same traffic handling class (e.g., the Ethernet express traffic class). A method aspect performed by the network element system comprises the step of receiving, from a network controller, information defining opening times for packet gates associated with network element ports. The opening times define a relative transmission order among first packet flow packets and second packet flow packets. Upon receipt of first and second packet flow packets at the respective ports, the packet gates are controlled based on the received information to trigger transmission of the first and second packet flow packets in the predefined transmission order.Type: ApplicationFiled: November 9, 2015Publication date: June 28, 2018Inventors: János Farkas, Stefano Ruffini, Balázs Varga

Patent number: 9621378Abstract: A router receives, from a BGP peer, a BGP update message including NLRI (VPN-NLRI) specific to a virtual private network, as well as path information including an address of a next hop for the VPN-NLRI. The router determines that there is no route to the next hop, modifies the filtering information to permit propagation of NLRI including the address of the next hop, and sends the modified filtering information to BGP neighbors. Alternatively, a router determines that such a BGP update message is due to be sent to a BGP peer. The router determines that the filtering information does not allow propagation, to the peer, of NLRI including the address of the next-hop, modifies the filtering information so as to permit propagation, to the BGP peer, of NLRI including the address of the next hop, and sends the BGP update message to the peer.Type: GrantFiled: November 27, 2012Date of Patent: April 11, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Balázs Varga, Balázs Peter Gerö, Shahryar Khan, David Sinicrope

Patent number: 9596176Abstract: A pseudowire redundancy network comprises a plurality of pseudowires (PW13, PW 14) attached to a provider edge node (201). For selecting an active pseudowire (PW13) to be used for forwarding user traffic, the provider edge node (201) determines a local preferential forwarding status for each of the pseudowires (PW13, PW14). The determined preferential forwarding status is active for no more than one of the pseudowires (PW13, PW14). The provider edge node (201) indicates the determined local preferential forwarding status of the pseudowires (PW13, PW14) to remote provider edge nodes (203, 204). Further, the provider edge node (201) receives indications of a remote preferential forwarding status for each of the pseudowires (PW13, PW14) from the remote provider edge nodes (203, 204). The provider edge node (201) then selects that one of the pseudowires (PW13, PW14) as active for which both the local preferential forwarding status and the remote preferential forwarding status is active.Type: GrantFiled: March 23, 2012Date of Patent: March 14, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Balázs Varga, Peter Balázs Gerö, Shahryar Khan

Patent number: 9264298Abstract: Methods and apparatus are disclosed for applying multiple Link Aggregation Group (LAG) entities on the same set of physical links, thus making bundling of individual services or conversations possible by the different LAG entities within Link Aggregation. Each LAG entity is configured such that a single physical link is Active and all the other links are Standby. Each LAG entity may be regarded as a “bundle.” Thus the services/conversations are bundled into a LAG entity and are handed-off on the Active link during normal operation. If service hand-off is not possible on the Active link (e.g., due to a failure), then the LAG entity switches over to a Standby link thus the service/conversation is handed-off on that formerly Standby link. Bundling may simplify operations of control and signaling.Type: GrantFiled: June 28, 2012Date of Patent: February 16, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Balázs Peter Gerö, János Farkas, Shahryar Khan, Panagiotis Saltsidis, Balázs Varga
