Embodiment 1

[0088] Such as Figure 4 As shown, in this embodiment, the client or user connects to multiple authenticators / agents through the access aggregation network, and each authenticator / agent is connected to the service network to which it belongs through its own IP network, that is, the operator network SP . Wherein, the clients or users may be various wired and wireless terminals, and have a DHCP client or user function. The authenticator / agent can have a DHCP relay agent function (DHCP Proxy or DHCP Relay), and can also have an authenticator (Authenticator) / AAA client or user function, and configuration information of the operator network to which it belongs is configured. The configuration information of the service network in each authenticator / proxy can be configured dynamically or statically. If dynamic configuration is adopted, the DIAMETER protocol or other protocols can be used, and the operator's policy server or other control equipment can dynamically configure the aut...

Embodiment 2

[0116] In this example, if Figure 5 As shown, a DHCP client or user is connected to an authenticator / agent through an access aggregation network, and multiple operator network SPs share an authenticator / agent. Authenticator / Proxy is connected to multiple operator network SPs through IP network. The DHCP client or user can be various wired and wireless terminals, and has the function of DHCP client or user. The authenticator / agent has the function of DHCP relay agent (DHCP Proxy or DHCP Relay), and can also have the function of authenticator (Authenticator) / AAA client or user, and is configured with the configuration information of each operator network connected to it, such as NAI, capabilities and other information. Likewise, network identification parameters in each authenticator / proxy can be configured dynamically or statically. The configuration method is the same as that described in Embodiment 1.

[0117] The operator's networks SP1 and SP2 respectively include an A...

Embodiment 3

[0127] In Embodiments 1 and 2, the authenticator / proxy may actually consist of multiple sub-authenticator / proxy devices. Such as Figure 6 As shown, authenticator / proxy 1 is composed of sub-authenticator / proxy A and sub-authenticator / proxy B.

[0128] When sub-authenticator / agent A and sub-authenticator / agent B are both valid, or in the case of load sharing or master-standby relationship, when the authenticator / agent receives a DHCPDiscover message with a DHCP Selection Option message, except As described in Embodiment 1 or 2, the authenticator / agent can judge and select the operator network according to the parameters in the DHCPSelection Option, and the authenticator / agent can also further according to its own current load and network resources. Status, traffic sharing policy, client or user sharing policy, etc. determine which sub-authenticator / proxy will forward the packet and process subsequent client or user data. At the same time, the sub-authenticators / agents can mak...

Abstract

The present invention relates to network communication technologies, and discloses a method, an apparatus, and a system for selecting a service network to improve network capabilities of serving the client. The method includes: receiving an address request message that carries service network selecting condition from a client or user; and judging whether preconfigured or stored service network configuration information meets the service network selecting condition, and forwarding the address request message to the service network that meets the service network selecting condition if the preconfigured or stored service network configuration information meets the condition. The apparatus includes: a message receiving and sending unit, a configuring unit, and a service network selecting unit. The embodiments of the present invention can select a service network for the client or user according to the requirements of the client or user, and improve the service capabilities of the network.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a method, device and system for selecting a service network for a client or user in the network. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is a TCP / IP standard that simplifies host IP configuration management. It dynamically specifies the IP address and configuration parameters for the client, such as IP address, subnet mask, default gateway, domain name server, etc. [0003] From the perspective of composition, DHCP is divided into two parts: DHCP Server (DHCP Server) and DHCP Client (DHCP Client). The main function of the DHCP server is to assign an IP address or other configuration parameters to the client according to the request of the DHCP client. It generally exists in routers, Layer 3 switches, or in the form of a dedicated DHCP server. A DHCP client is a host that uses the DHCP protocol to o...
