Abstract

A method for simply arranging VPN network through self-organized domain includes setting up interconnection-inter-working of at least two nodes in star network, enabling to send information of all nodes in star network and information of external access node mutually by the node when connection of one external node to any node in star network is set up, automatically setting up connection of another external node to he other node in star network when connection of another external node to any node in star network is set up and forming mesh network by configured star network.

Description

Simplify the method for disposing the VPN network by organizing the territory certainly
Technical field
The present invention relates to a kind of method of disposing the VPN network of simplifying, particularly a kind of by organizing the method that the VPN network is disposed in the territory simplification certainly.
Background technology
" a kind of method of reducing VPN network arranging " disclosed in the Chinese patent 200510051352.0.Its purpose is by with the relevant together consideration of MPLS label and vlan information, realize simplifying arrangement based on MPLS two-layer VPN network, thereby in VPN networking application and arrangement, bring more convenience and flexibility, this invention operates on the existing two-layer VPN wide area network basis based on MPLS, described network comprises at least one source end PE (office side) equipment and pair of end PE (office side) equipment, mainly comprises the steps:
(a) after source end PE equipment receives the Layer 2 data frame that has vlan information,, obtain the ID of VPN by the mapping relations table of VLAN and VPN;
(b) carry out the forwarding lookup of target MAC (Media Access Control) address by the ID of VPN, obtain the information of purpose CE and the information of the two-layer label of encapsulation MPLS;
(c) after PE equipment in opposite end is received Layer 2 data frame after the encapsulation,, change the vlan information of described encapsulation and transmit by the VPN ID that is provided with mapping relations table to VLAN.
Yet, adopt said method to realize that there is following weak point in VPN.
1, too complex in the deployment of VPN.
2, the complicated in the past deployment probability that causes artificial configuration to make mistakes is higher.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art, provide a kind of branch office network to interconnect with enterprise's cross-region, centralized and unified management, and effectively carry out arrangement and upgrading, to ensure whole net safety and to simplify the method for disposing the VPN network by organizing the territory certainly.
Purpose of the present invention can reach by following measure:
Thisly simplify to dispose the method for VPN network by organizing the territory certainly, operate on the existing star network basis, described star network is meant the VPN network with star topology structure, and its special character is that this method comprises the steps:
At least two nodes in a, the star network are assumed to be to set up between node A, the Node B and interconnect;
B, when an external node, be assumed to be arbitrary node in node C and the star network, after supposing that node A connects, by node A the information of all nodes in the star network and the information of outside access node C are sent mutually, the Node B in outside access node C and this star network connects automatically;
C, when another external node, suppose that the arbitrary node in node D and the star network connects, then should outside access node D will be automatically and in the star network some other nodes connect;
D, by that analogy makes the star network of configuration form mesh network.
The present invention has following advantage:
1, makes the star network of configuration simply form mesh network, make the deployment of VPN network become easier.
2, to have reduced the people be the probability of makeing mistakes to simple network design.
Description of drawings
Fig. 1 is that node A in the star network of the present invention, Node B are set up the schematic diagram that interconnects.
Fig. 2 is the schematic diagram that node A connects in external node C of the present invention and the star network.
Fig. 3 be external node C of the present invention insert after the star network with star network in the schematic diagram that connects automatically of Node B.
Fig. 4 is that node A sets up the schematic diagram that interconnects in the present invention another external node D and the star network.
Fig. 5 be another external node of the present invention D insert after the star network with star network in the schematic diagram that connects automatically of Node B, node C.
Embodiment
The present invention is further detailed in conjunction with the accompanying drawings below:
Should simplify the method for disposing the VPN network based on organizing the territory certainly, and operate on the existing star network basis, described star network is meant the VPN network with star topology structure, and it comprises the steps:
At least set up between node A, the Node B in a, the star network interconnect (seeing also shown in Figure 1);
B, after node A connects in an external node C and the star network, this node A the information that has the Node B in this network send to rigidly connect into node C, begin then to connect; This node A also can rigidly connect into the information of node C send to the Node B that connects with node A, begin to connect (seeing also shown in Figure 2) Node B in outside access node C and this star network connect automatically (seeing also shown in Figure 3) then;
Arbitrary node among c, the node A when in another external node D and the star network, Node B, the node C is assumed to be node A and connects, and then should Node B, node C's outside access node D in automatic and the star network be connected;
D, by that analogy makes the star network of configuration form mesh network; Described mesh network is meant the VPN network with fully connected topology.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.

Claims (1)

1, a kind ofly simplify to dispose the method for VPN network by organizing the territory certainly, operate on the existing star network basis, described star network is meant the VPN network with star topology structure, it is characterized in that this method comprises the steps:
