摘要： A method of updating conversation allocation in link aggregation is disclosed. The method starts with verifying that an implementation of a conversation-sensitive link aggregation control protocol (LACP) is operational at a network device of a network for an aggregation port. Then it is determined that operations through enhanced link aggregation control protocol data units (LACPDUs) are possible. The enhanced LACPDUs can be used for updating conversation allocation information, and the determination is based at least partially on a compatibility check between a first set of operational parameters of the network device and a second set of operational parameters of a partner network device. Then a conversation allocation state of an aggregation port of the link aggregation group is updated based on a determination that the conversation allocation state is incorrect, where the conversation allocation state indicates a list of conversations transmitting through the aggregation port.

摘要： A technique for controlling network routing in a network (100) is provided. The network (100) includes a first end node (102) and a second end note (104). The end nodes are connectable along a first routing path (106) by at least one link (113). The network (100) further provides a second routing path (108) including the first end node (102) and the second end nodes (104). As to a method aspect of the technique, one or more queues (402) are provided. Each of the queues (402) serves at least one tunnel (Tunnel_1; Tunnel_2) along the first routing path (106). A switching of the tunnel (Tunnel_1) to the second routing path (108) is triggered based on a combination of two pieces of information. A piece of information includes information as to a queue build-up at the queue (504) serving the tunnel (Tunnel_1). Another piece of information includes information as to a capacity of the link (113) of the first routing path (106).

摘要： A method is provided for transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers, the bearers each carrying data packets that relate to different ones of a plurality of services. In the method a multi-level bandwidth profiling scheme is applied to the data packets of each bearer. A series of information rates are assigned to a bearer, the profiling scheme identifying and marking each data packet of the bearer based on a desired resource sharing according to the minimum information rate with which the packet is conformant. The marked data packets are forwarded for transport through the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets identified by the profiling and marked as only being conformant with a higher information rate are discarded before any data packets marked as being conformant with a lower information rate.

摘要： 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.
