The embodiments of the present invention disclose a method, apparatus and system for implementing routing aggregation, which relate to communication field, and solve the problem that too many routings advertised on the DHCPv6 relay agent leads to huge number of routing table entries of the backbone network. The technical solution of the present invention comprises: sending a message to a dynamic host configuration protocol DHCPv6 relay agent, such that the DHCPv6 relay agent generates an aggregation routing of requesting router prefix routings according to the message; wherein the message comprises information about a prefix pool which assigns address prefixes to the requesting routers access to the DHCPv6 relay agent or aggregation routing destination address information generated according to the information about the prefix pool. The method, apparatus and system for implementing routing aggregation may be applied in DHCPv6 network constructions.

A method, a device, and a system for offloading network traffic are provided, which are applied in the field of mobile communications. An offloading device located before a Serving General Packet Radio Service Support Node (SGSN) receives a data stream of a user sent by a base station, obtains an offloading policy of the user from the offloading device and/or obtains the offloading policy of the user from a policy server, and forwards the data stream according to the offloading policy. Accordingly, the offloading device can obtain the corresponding offloading policy according to the data stream sent by a forwarding plane, send a data stream of low value, low real-time performance requirement, or low priority to the Internet or another specific networks, and send a data stream of high value, high real-time performance requirement, or high priority to high-value devices, thereby reducing the networking cost.

A method comprises converging resource reservation requests from users, wherein the resource reservation requests contain bandwidth values to be occupied for data transmission; determining a total bandwidth value comprising a sum of the bandwidth values to be occupied for data transmission in the converged resource reservation requests; determining the total bandwidth value is larger than a preset bandwidth threshold of a first transmission path having an identifier (ID) number; and establishing a second transmission path using the identifier (ID) number of the first transmission path distributed to the users, wherein an ID number of the second transmission path is the ID number of the first transmission path and a bandwidth value of the second transmission path is larger than or equal to the total bandwidth value.

Method, device, and system for admission control in metropolitan area network

The present invention discloses a method, system, and device for admission control and pertains to the communications field. The method includes: admitting a subscriber for watching a multicast video only if each multicast bandwidth management device has sufficient remaining bandwidth after receiving a multicast video request from the subscriber; refusing the subscriber for watching the multicast video if any multicast bandwidth management device has insufficient bandwidth and fails to borrow bandwidth from a unicast bandwidth management device; and after receiving a unicast video request from the subscriber, admitting the subscriber for watching a unicast video only if remaining unicast bandwidth corresponding to a multicast bandwidth management device in each level is sufficient, or else, refusing the subscriber for watching the unicast video. Through bandwidth negotiation between the unicast bandwidth management device and each multicast bandwidth management device, admission control is implemented.

A method for processing request for network address/port translation in a communication network includes: firstly, the first network entity transmits a network address/port request message which carries the priority information of the request; after receiving the request, the second network entity allocates the corresponding network address/port for the first network entity according to the priority information in the request message; finally, the second network entity returns the allocated network address/port information to the first network entity, and the allocated network address/port information is used for performing the network/address translation. By realizing the invention, the service having high priority, e.g. emergency service, can be processed for the network/address translation firstly to ensure the reliability of high priority service communication. Furthermore, it can provide distinguished process service of the network address/port translation during a network operation, and thereby enhancing the flexibility of the network operation.

A resource initialization method and system, and a network access server are provided. The resource initialization method includes: receiving a network access request transmitted from a User Equipment (UE), where the network access request includes: UE identity (ID) information; locally searching for, according to the UE ID information in the network access request, and find a preconfigured unicast and multicast resource threshold corresponding to the UE ID information; and transmitting the unicast and multicast resource threshold of the UE to a Resource Manager (RM), so that the RM assigns unicast resources and multicast resources according to the unicast and multicast resource threshold. Through the method, the process of obtaining the unicast and multicast resource threshold can be simplified, and thus the efficiency of resource initialization configuration is improved.

A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.

The present invention relates to the field of communications technologies, and discloses a method, an apparatus, and a system for allocating Internet Protocol Television (IPTV) resources to save bandwidth resources in the IPTV service. The method includes the following: a multicast access control entity allocates resources to a unicast access control entity through an intermediate network entity when unicast resources are not enough; and the unicast access control entity allocates resources to the multicast access control entity through the intermediate network entity when multicast resources are not enough. The present invention is primarily applicable to IPTV technologies.

Method, apparatus and system for allocating IPTV resources

A method for resource admission control process, an Access-Resource and Admission Control Function entity and a Service-based Policy Decision Function entity, wherein the method includes: sending an Admission Request message, which carries the current media stream address information, to an Access-Resource and Admission Control Function entity (A-RACF) in an originating home network from a Service-based Policy Decision Function entity (SPDF) when the SPDF successfully configures an IP Multimedia Subsystem (IMS) connection for a Core Border Gateway Function entity (C-BGF) in the originating home network; and performing a resource admission control process for a corresponding media stream by the A-RACF according to the received Admission Request message. With the method of the present invention, the resource admission control process performed by the A-RACF on the media stream may become meaningful.
