20080285559 | Method, Device And System For Implementing Multicast Connection Admission Control - Implementing multicast connection admission control is provided, and includes: calculating a currently remaining multicast support capability of a network-side functional unit upon receiving a program request initiated from a user; and admitting an access of the user when a support capability required for a program as requested by the user is below or equal to the currently remaining multicast support capability of the network-side functional unit. | 11-20-2008 |
20090147786 | MULTICAST SERVICE PROCESSING METHOD AND ACCESS EQUIPMENT - A multicast service processing method and access equipment are disclosed. The method includes: receiving multicast program request message from terminal device, inquiring about program rating parameters according to said multicast program request message, wherein the program rating parameter includes multicast group IP address and multicast program rated priority, generating multicast program data according to the program rating parameters, sending the multicast program data to the terminal device. | 06-11-2009 |
20100330418 | POLYMER ELECTROLYTE, BATTERY AND METHOD - A polymer electrolyte comprises a first polymeric matrix, a second polymeric matrix, and a lithium salt. The first polymeric matrix comprises pores. The second polymeric matrix is disposed in at least some of the pores of the first polymeric matrix. The lithium salt is disposed in at least some of the pores of the first polymeric matrix. | 12-30-2010 |
20120191825 | METHOD, DEVICE, AND SYSTEM FOR ALLOCATING ADDRESS IN IP NETWORK - A method for allocating an address in an IP network includes: receiving, by a server, a request message from a client, where the client is connected to the server through at least one routing device, and the request message received by the server carries a device identifier of a preceding stage routing device of the client; obtaining, by the server, according to the device identifier of the preceding stage routing device, a first address prefix pool that is pre-allocated to the preceding stage routing device, and allocating a second address prefix pool to the client according to the first address prefix pool, where an address range corresponding to the second address prefix pool falls within an address range corresponding to the first address prefix pool; and sending, by the server, the second address prefix pool to the client. | 07-26-2012 |
20130021896 | METHOD, SYSTEM, AND DEVICE FOR PROTECTING MULTICAST IN COMMUNICATION NETWORK - The present invention discloses a method, a system, and a device for protecting multicast in a communication network. The technical solution of the present invention is: In a communication multicast network, a main node and a backup node serve as root nodes to generate two multicast trees simultaneously; the multicast tree that uses the backup node as a root node is set to be in a silent state; when the network is faulty, and the current main multicast tree is unable to forward multicast packets to all leaf nodes in the multicast tree, the silent state of the backup multicast tree is canceled and the backup multicast tree starts forwarding the multicast packets. | 01-24-2013 |
20130089092 | METHOD FOR PREVENTING ADDRESS CONFLICT, AND ACCESS NODE - A method for preventing address conflict and an access node are provided. The method includes: when an uplink packet is received, obtaining a medium access control MAC address and a link local address LLA which are of a client and are carried in the packet, where the packet is an IPV6 protocol packet borne over Ethernet; generating a corresponding VMAC address for the MAC address according to a predetermined rule; generating a corresponding VLLA according to the VMAC address, where the VMAC address and the VLLA have one-to-one correspondence, and the generated VMAC address and VLLA are unique in one network under a broadband network gateway BNG; replacing, with the VMAC address and the VLLA, the MAC address and the LLA that are in the packet; and transmitting an uplink packet including the VMAC address and the VLLA. In addition, an access node is also provided. | 04-11-2013 |
20140105214 | MESSAGE FORWARDING METHOD, SYSTEM, AND RELAY AGENT DEVICE - The present disclosure provides a message forwarding method and system, and a relay agent device. The forwarding method includes: receiving a first DHCPv6 message from a DHCPv6 client through a layer-3 interface; generating a Relay-forward message, where the first DHCPv6 message is encapsulated into the Relay-forward message and an identifier of the layer-3 interface is added therein; and sending the Relay-forward message to a DHCPv6 server. | 04-17-2014 |
20140153442 | Method, Device, and System for Packet Processing - The present disclosure provides a method, a device, and a system for packet processing, where the method includes: receiving a protocol packet from a downstream device, where the protocol packet carries uplink port information of the downstream device and the user VLAN of the downstream device; learning port types of the present device based on the uplink port information and classifying the user VLAN of the present device and the user VLAN of the downstream device based on the user VLAN of the downstream device; and forwarding the received packet based on configuration information stored on the present device, where the port type or types to which each VLAN type can be added are specified in the configuration information. | 06-05-2014 |
