Embodiment Construction

[0051] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0052] like figure 2 As shown, it is a scheduling method of a firewall according to the present invention, including:

[0053] Step 11, the gateway support node GGSN assigns an IP address to the current user who activates the PDP session; this step is specifically: after the user finishes PDP activation, the GGSN assigns an IP address to the user.

[0054] Step 12, the GGSN selects a firewall from the at least two firewalls according to the polling mechanism and user allocation history of the at least two firewalls; the at least two firewalls form a firewall pool group. The user allocation history of at least two firewalls is; assuming there are two firewalls, assigning firewall A to the previous user of the current user, and assigning firewall B to th...

Abstract

The invention provides a scheduling method, a system and gateway GPRS support nodes (GGSN) for firewalls. According to the scheduling method for firewalls, the gateway GPRS support nodes (GGSN) assign IP addresses to active users for activating sessions under the packet data protocol (PDP). The GGSNs select one firewall out of at least two firewalls according to the polling mechanism and the user assignment histories of the at least two firewalls. After that, the corresponding relationship between IP addresses and the selected firewall is established. The invention solves the capacity bottleneck problem of Gi firewalls in the prior art.

Description

technical field [0001] The present invention relates to the communication field, in particular to a firewall dispatching method, system and GGSN. Background technique [0002] Existing mobile packet domain network architecture such as figure 1 Shown: [0003] SGSN (ServingGPRSSupportNode) is a GPRS (General Packet Radio Service) service support node. As an important part of the packet domain equipment of the packet domain core network, the SGSN mainly completes the routing and forwarding of packet data packets, mobility management, session management, and logical chaining. Route management, authentication and encryption, bill generation and output and other functions. [0004] GGSN (GatewayGPRSSupportNode) is a gateway GPRS support node, which mainly acts as a gateway. GGSN is responsible for responding to the PDP (PacketDataProtocol, Packet Data Protocol) activation request initiated by the terminal, assigning the operator's private network IP address to the terminal, es...
