Abstract: A reliability processing method and system in networking of Metro Ethernet Network providing multi-service are provided. The method includes: establishing a Virtual Router Redundancy Protocol (VRRP) group with at least two service control gateways, establishing network connections between an access device (UPE) and the service control gateways in the Virtual Router Redundancy Protocol group by a Virtual Private LAN Service (VPLS); establishing Layer 2 service and Layer 3 service connections between an active service control gateway and the Access device after active and standby service control gateways in the Virtual Router Redundancy Protocol group are determined according to a processing result of a Virtual Router Redundancy Protocol message, and performing Layer 2 service and Layer 3 service processing.

Therefore, the reliability of the Layer 2 and Layer 3 services of the MAN may be sufficiently guaranteed, and the overhead of the system may be reduced significantly.

Abstract: A method and system for implementing network device access management. The system includes at least one device domain storage unit and at least one Access Server (AS), and the method groups all network devices into at least one device domain managed by at least one AS; sets a uniform communication attribute for each device domain; determines, by the AS, whether a communication device belongs to the device domain managed by the AS according to information carried in a service request from the communication device, and if so, the communication attribute set for the network device is obtained, and a correspondence relationship between an identifier of the network device and the obtained communication attributes is created and stored; otherwise, access management on the communication device served as a user device is performed.

Abstract: A method for service binding includes: identifying a service provider identifier of a terminal and binding the terminal into a corresponding tunnel dependent upon the identified service provider identifier. The present invention implements dynamic binding of a terminal with a service through identifying a service provider identifier of the terminal, which offers more flexible selection of a service by a user, a reduced operation and maintenance cost of an operator, good extensibility of a network service and facilitated deployment of the service.

Abstract: In the field of network communications, a method, a system, a gateway device, and an authentication server for allocating multi-service resources while multiple services of a same user access to a network are provided. The method includes the following steps. A service request message sent by a first service terminal is received. Service capability and user identification of the first service terminal and a count of available resources that corresponds to the user identification are obtained. Resources are allocated for the first service terminal based on the service capability and the user identification of the first service terminal and the count of the available resources that corresponds to the user identification. Thus, the configuration of the gateway device is simplified, and the scale deployment for different services is achieved.
