    Abstract: Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.

    Abstract: After fixing the physical address of a wireless video transmission device (110) to a route address or the like, it is possible to shorten the switchover time by having a conversion table (222) provided that maps the physical addresses on the wireless video reception device (120) side, since it does not occur that the addresses of AV equipment connected by wire with the wireless video transmission device (110) are changed, even if the physical address of the wireless video reception device (120) changes. Further, by performing split transfer of the CEC messages, it is possible to carry out transmission of the CEC messages promptly and to suppress reception confirmation bits with respect to CEC messages for which there exists no destination.

    Abstract: Embodiments of this application disclose a segment routing over internet protocol version 6 SRv6-based communication method and a related apparatus. The method may be used in a campus network, and the method includes: A layer 2 gateway generates an Ethernet virtual private network instance EVI media access control EVI-MAC route, where the EVI-MAC route includes an Ethernet virtual private network instance segment identifier EVI SID, the EVI SID is an SRv6 SID applied for by an EVI from the layer 2 gateway, and a MAC address carried in the EVI-MAC route does not include a MAC address of each host in the EVI. The layer 2 gateway advertises the EVI-MAC route to a layer 3 gateway. After the layer 2 gateway advertises the EVI-MAC route to the layer 3 gateway, the layer 3 gateway does not receive a MAC address of a host from the layer 2 gateway. In this way, MAC routing pressure on the layer 3 gateway is effectively reduced, so that the layer 3 gateway can establish communication connections with more hosts, thereby effectively expanding a network capacity.

    Abstract: A Stream Control Transmission Protocol (SCTP) cluster of multiple SCTP-servers is defined in such manner that some of the servers are assigned Active Role where others are assigned Standby Role with the purpose of ensuring uninterrupted SCTP-connections between the SCTP-cluster and any number of SCTP-clients. The Standby Servers use the same Internet Protocol (IP)-address(es) on the SCTP bound interfaces as their assigned Active Server. The Active Servers are effectively communicating to the SCTP-clients, where the Standby Servers are communicating to their assigned Active SCTP-Server using a separate backchannel TCP-connection. Over that backchannel connection the Standby Server receives regular updates from the Active Server. These updates hold enough information so that the Standby Server could locally simulate SCTP-negotiations and create SCTP-associations as if the SCTP-negotiations were performed directly with the SCTP-Clients. In this manner the Standby Servers are fully synchronized and ready in case of an Active Server failure to continue the SCTP-communications without any interruption. This handover does not involve any subsequent action from the SCTP-clients so that the SCTP-clients are unaware that such a handover took place.

    Abstract: This invention relates to a method and system for fast processing real-time media stream data package, which provides a method and system for fast transporting real-time media stream data package based on the Real-time Transport Protocol/ Real-time Transport Control Protocol of User Datagram Protocol for network nodes such as media gateway, Integrated Access Device (IAD) and multimedia terminal. The improvement of the system lies in the adding of an IP data package fast filter module, a UDP fast sending module and a policy ARP table process module based on local UDP port. The method comprises: fast receiving the real-time media stream data package transmitted on the basis of RTP/RTCP protocol; fast sending the real-time media stream data package transmitted on the basis of RTP/RTCP protocol; and a policy ARP table based on UDP port and its refurbishing system. Compared to the conventional receiving and sending of TCP/IP protocol stack and SOCKET programming, the present invention can fast process real-time media stream data package, improve the processing ability of equipment, reduce network delay of the media stream data package, thereby improving the QoS.
