20120263177 | METHOD FOR MANAGING CUSTOMER EDGE DEVICE AUTOMATICALLY AND PE DEVICE - A method for managing a customer edge device includes: receiving, by a UNI set in a third-party operator network, an E-LMI packet sent by a VUNI set in a service provider network, where the VUNI is configured to manage a RUNI correlated with an EVC in the third-party operator network; converting, by the UNI, a unicast DMAC address in the E-LMI packet into a multicast DMAC address; and sending, by the UNI, the converted E-LMI packet to a CE device connected with the UNI. The E-LMI packet sent by the VUNI set in a service provider network may penetrate the third-party operator network, so that the management information of the service provider network can be transmitted to the CE device that is connected with the third-party operator network through the UNI. | 10-18-2012 |
20120269086 | PACKET LOSS DETECTING METHOD AND APPARATUS, AND ROUTER - A packet loss detecting method includes: a first router counts received packets and sent packets respectively according to a class of service value of a packet in each tunnel; the first router generates a first packet loss detection packet corresponding to the class of service value, sends the first packet loss detection packet to a second router at a peer end, and receives a first packet loss response packet returned by the second router; and the first router corresponds a class of service value, and measures a packet loss value according to a locally recorded count value and a count value carried in the first packet loss response packet. With the technical solution, packet disorder does not occur when packet loss measurement is performed for a pseudo-wire with multiple classes of service. In addition, traffic detection occupies a smaller bandwidth. | 10-25-2012 |

20130132995 | SERVICE ACCESS METHOD, DEVICE, AND SYSTEM - The present invention provides a service access method, device, and system, and relates to the field of television services, to guarantee multicast security of a network device. The method includes: obtaining an authorized multicast address list according to program channel list information provided by a server; receiving an Internet Group Management Protocol IGMP packet request sent by a user terminal device, where the IGMP packet request carries a multicast address; verifying the multicast address in the IGMP packet request according to the multicast address list; and sending a media data stream corresponding to the verified multicast address to the user terminal device. The solutions of the present invention are suitable for realizing the security of multicast of network device. | 05-23-2013 |
20140016639 | MULTICAST METHOD AND MULTICAST DEVICE - The present invention provides a multicast method and a multicast device. The method includes: receiving a multicast request from a user, where the multicast request includes multicast channel information and a user VLAN tag; selecting a first target multicast VLAN from pre-configured multiple multicast VLANs; after replacing the user VLAN tag in the multicast request with the first target multicast VLAN tag, forwarding the multicast request to a multicast router; receiving multicast traffic sent by the multicast router through the first target multicast VLAN, and forwarding the multicast traffic to the user. In the present invention, a target multicast VLAN is selected according to multicast channel information, so that multicast requests for the same multicast channel can be added to the same multicast VLAN. In this way, only one copy of multicast traffic of the same channel exists on a local area network, thereby saving network bandwidth resources. | 01-16-2014 |
20140105210 | METHOD AND APPARATUS FOR INTERCEPTING MULTICAST PROTOCOL PACKET AND SWITCH - The present disclosure provides a method and an apparatus for intercepting a multicast protocol packet and a switch. The method for intercepting a multicast protocol packet includes: acquiring multicast work information of a router; acquiring a multicast protocol parameter of the switch according to the multicast work information of the router, where the multicast protocol parameter includes an interval of sending general query packets, a robustness variable, and a query response interval; acquiring port aging time of the switch according to the multicast protocol parameter of the switch; and aging a port if no multicast protocol packet is received on the port within the port aging time. The present disclosure further provides a corresponding apparatus and a switch including the apparatus. | 04-17-2014 |
20140119187 | PROCESSING METHOD, DEVICE AND SYSTEM FOR CONTROLLING PACKET BROADCAST - The present invention provides a processing method, device and system for controlling packet broadcast. The method includes: obtaining, by a first device, a cluster MAC address, and determining an egress port of the first device corresponding to the cluster MAC address; and establishing, by the first device, a cluster table, where the cluster table is used to record correspondence between address information and the egress port of the first device, and the address information includes the cluster MAC address, so that the first device forwards a packet from the egress port of the first device corresponding to the cluster MAC address according to the cluster table after receiving the packet whose destination MAC address is the cluster MAC address. Embodiments of the present invention can reduce network traffic burdens. | 05-01-2014 |
20140146659 | RENDEZVOUS POINT CONVERGENCE METHOD AND APPARATUS - The present invention discloses a rendezvous point convergence method and apparatus and relates to the field of communications, to solve a problem that an entire network cannot work normally for a long time because a network device cannot send a candidate RP advertisement message to a bootstrap router BSR when the network device served as a rendezvous point RP is entirely faulty. In the present invention, when a route of an original working RP is unreachable, a first node receives a bootstrap message sent by a BSR, where Holdtime of the original working RP carried in the bootstrap message is 0; and the first node disables the original working RP and enables a candidate RP as a new working RP according to the bootstrap message. The present invention is applicable to the field of communications to implement rendezvous point convergence. | 05-29-2014 |
