Abstract: 本发明实施例提供一种恢复用户业务的方法和装置，以快速恢复用户业务，增强用户单播业务的可靠性。所述方法包括：侦听连接第一路由桥的信任端口；根据所述侦听的侦听结果，判断所述第一路由桥是否具有继续转发来自C-VLAN的流量的权限；若所述第一路由桥不再具有转发来自所述C-VLAN的流量的权限，则将来自所述C-VLAN的流量广播至第二路由桥，由所述第二路由桥转发来自所述C-VLAN的流量。本发明实施例提供的方法能够在指定路由桥出现故障而无法再承担流量转发的职能或者用户VLAN的指定转发者发生变更时，可以迅速切换转发的路径，使用户的单播业务流量及时转发，大大缩短了业务的中断时间，实现业务流量的高可靠性。

Abstract: A Method, a system and a device for user access security control are provided. The method comprises: receiving an access request message which contains the user link ID; parsing the access request message to obtain the user link ID; judging whether the access request message satisfies the preset access condition according to the user link ID ; if so, permitting the user corresponding to the user link ID to access. The system includes user nodes, an access device and a control device. The access device includes a receiving module, an identifier inserting module and a transmitting module. The control device includes a receiving module, a parsing module and a processing module. The user link can be identified uniquely under the multi-service mode by configuring logic interface on BNG devices, thereby the security control policy such as access control, bandwidth control and multicast control for a single user link is performed by the user link ID information according to the preset security control policy of the logic interface.

Abstract: A method for multicast forwarding which is used in the multicast among different internet protocol networks is disclosed. The method includes the following steps: receiving the first multicast group joining request from the first internet protocol network which the host is located in; the first multicast group joining request is sent by the host when it requests to join the multicast group which is corresponding to the multicast source located in the second internet protocol network; joining the multicast group by the way of acting as the agent of the host; receiving the multicast data of the multicast group from the second internet protocol network and sending the multicast data of the multicast group to the host. The corresponding computer program product, computer readable storage medium and multicast router are also disclosed. The multicast source can be used, wherein the multicast source and the host are located in different internet protocol networks.

Abstract: A method, system and equipment for accessing layer 2 visual private network (L2VPN). The method involves establishing a PPP connection of customer premise equipment and an access server through a bridge control protocol (BCP) way (101). A data message of a customer is transmitted to a corresponding L2VPN according to pre-set corresponding rules based on customer connecting information (102). The method achieves accessing of L2VPN by only supporting PPP connected low speed network or leased network, because layer 2 data packet is carried in the PPP connection by BCP way. Different customers can be distinguished through the physical circuit mark connected by PPP or field mark dialed by customer, so as to perform different processes.
