The embodiment of the present invention provides a tunnel net transparent to user on existing network, and is replaced using tunnel net
Legacy network forwards to IP messages.Therefore one or more can be increased in each subnet of existing internal network
Linux server, such as server is configured to be in communication with each other by udp protocol on existing internal network, these communication chains
The set on road forms tunneled network, thus can be using these servers as tunneled network tunnel nodes, and tunnel nodes can
To regard the virtual router of tunneled network as.Tunneled network is directly established on existing network, it is possible to reduce to existing network
Transformation expense, reduce to expense of server configuration modification etc..
Tunneled network includes central management server, each tunneled network can be matched somebody with somebody by central management server
Put, including at least following configuration：
(1) topological arrangement.
Topology information i.e. in configured tunneling technique network between tunnel nodes (i.e. virtual router).Tunneled network and traditional net
Network (such as IP network) is different, and the router of legacy network is in communication with each other by Routing Protocol, such as open most short
Heat source (Open Shortest Path First, OSPF) agreement, or routing information protocol (Routing
Information Protocol, RIP) etc., these agreements are all based on broadcasting to realize again, i.e. the network topology of legacy network
Information is sent to other routers by broadcast.
For tunneled network structure on traditional IP, the tunnel nodes of tunneled network are usually located at difference in the present embodiment
Subnet on, there was only cast link between tunnel nodes, the automatic topology information for obtaining tunneled network of broadcast can not be passed through.Therefore
The topology information of tunneled network, such as manual configuration or the subnet topology configuration according to legacy network can be pre-configured with, and
Each tunnel nodes can also configure the information of some downstream links, and downstream links are the purpose tunnels that tunnel nodes E-Packet
The set of node, therefore the topology information of tunneled network can be rendered as a digraph.Certainly, for a certain tunnel nodes and
Say that its destination tunnel node to be sent to is downstream node, and when it receives the message of other tunnel nodes, other tunnel sections
Point is its upstream node, therefore the link of tunneled network can be two-way communication.
(2) route information table configures.
Route information table can describe the responsible outlet IP scopes of each virtual router (i.e. tunnel nodes).Channel message
When being forwarded in tunneled network, one outlet node (destination tunnel node) must be routed to, this Egress node will can be reported
Text is reduced on the legacy network of subnet where original IP messages are sent to it.After each virtual router receives channel message
Its purpose IP can be checked, if performing above-mentioned reduction if exporting in IP scopes, be forwarded to the step of subnet.
(3) quality of service configuration.
Quality of service configuration information can be regarded as flow control plan of the tunneled network for the data message of different demands
Set slightly, the demand of flow is with { source IP, source IP mask, source port, Target IP, Target IP mask, target port, transmission
Layer protocol } etc. information describe, strategy is the information such as flow control information { bandwidth share, preferential route, data compression rate }
To describe.Above-mentioned flow control information can be applied by virtual router during channel message forwards.
Central management server establishes simultaneously management tunnel network by configuring above- mentioned information.It can be believed according to the topology of configuration
Configuration server is ceased, tunneled network, such as tunneled network based on UDP links, and configuring are established using the tunnel nodes on subnet
The contents such as the route information table and quality of service information that are used in tunneled network aspect.
In the present embodiment, tunneled network forms an abstract network, virtual router (the i.e. tunnel section of tunneled network
Point) be both IP messages come in and go out tunneled network critical point, be also responsible for inside tunneled network carry out message routing node.Cause
This, server in network can gateway carrys out transparent use tunnel net and taken by default with the virtual router in itself subnet
The critical point that subnet connects with tunneled network when business, i.e. tunnel nodes, and the section of data is transmitted between the tunnel nodes of tunneled network
Point, realize the transparent transmission of data between subnet.Therefore tunnel nodes mainly perform following operating procedure：
(1) message forwards
Virtual router can necessarily be located after the IP messages that legacy network (such as subnet) is sent are received to IP messages
Reason (such as compression), then increase the first-class encapsulation operation of tunnel net message before message after treatment and IP messages are packaged into tunnel
Message, then tunnel network packet is subjected to routing forwarding, stream control can be carried out according to quality of service information wherein during routing forwarding
Operated Deng processing.
(2) critical point of tunneled network
Virtual router is that the processing such as encapsulation can be compressed to IP messages in message entry/exit tunneled network, and right
Channel message is decompressed and unsealed etc. reason, such as after channel message is received, can be according to route information table to tunnel
Message carries out routing forwarding, i.e., determines for the channel message to be forwarded to the virtual road of next-hop of transmission link by route information table
By device, or it is reduced into original IP messages and turns to be dealt into legacy network by critical point.
Therefore, tunnel nodes can be responsible for as the critical point of the IP messages discrepancy tunneled network of legacy network (subnet)
Discrepancy of the IP messages between legacy network and tunneled network.Also, for what is established between servers according to topological arrangement
Tunneled network, the routing forwarding of message can be realized in tunneled network aspect and ensure quality of the message in repeating process,
The IP messages into tunneled network are enable to be routed to optimal Egress node, and energy by optimal path in tunnel net
It is enough to be forwarded according to the quality of service information in central management server.
Based on above-mentioned discussion, in an alternative embodiment of the invention, node forwarding module 2008, it is additionally operable to report the IP
Before text is packaged, when the flow control information includes compression ratio, the IP messages are carried out according to the compression ratio
Compression.I.e. it is determined that the IP messages that subnet uploads first can be compressed when needing forwarding according to compression ratio to IP messages, then
IP messages after compression are packaged, generate corresponding channel message, such as heading can be added on IP messages and configured
The Information encapsulations such as corresponding host-host protocol are into the channel message based on the host-host protocol.
The node forwarding module 2008, for selecting the channel message in the tunnel according to the preferential routing iinformation
Transmission link in road network；And/or configure the channel message according to the bandwidth share information and sent in transmission link
Shi Zhanyong bandwidth information, and determine whether the channel message needs current limliting according to the bandwidth share information, wherein,
Determine that the channel message needs that the channel message is added in waiting list during current limliting, it is determined that the channel message not
When needing current limliting, the channel message is transmitted.
After channel message is generated, it can such as believe according to flow control information configured tunneling technique message according to preferential route
Breath selection channel message transmission link, and for example according to bandwidth share information configured tunneling technique message take bandwidth information and really
Determine whether channel message needs current limliting etc., any of the above-described kind of flow-control operation can be performed in actual treatment, or any combination thereof
Flow-control operation.
Such as a certain channel message priority is higher, according to preferential routing iinformation high-speed link can be selected to send.If certainly
The priority of a certain channel message is relatively low, then can select the same relatively low generic link forwarding of priority.If high priority
Message and low priority message try concurrently to forward by a certain link, then limited forwarding high priority message, and low priority
Message is then added in waiting list according to the busy degree selection of the spare time of link, is sent according to queue sequence.
The node forwarding module, for searching route information table according to the transmission link of the channel message, by described in
Channel message is transmitted to the next-hop tunnel node of tunnel nodes described in the transmission link.
The node forwarding module, for receiving the channel message of other tunnel nodes transmission, and detect the tunnel section
Point whether be the channel message destination tunnel node；When the tunnel nodes are not the purpose tunnel sections of the channel message
During point, the next-hop tunnel that the channel message is transmitted to tunnel nodes described in the transmission link by route information table is searched
