Description
Technical field
The present invention relates to the technical field that wide area network accelerates, more particularly to a kind of wide area network (Wide based on TCP/UDP
Area Network, WAN) acceleration system and method.
Background technology
Wide area network, also referred to as telenet, the generally very big physical extent of bridging, the scope covered is from tens kilometers to several
Thousand kilometers.The communication subnet of wide area network mainly uses packet-switch technology, can utilize public packet switching network, satellite communication network
With wireless, packet-switched net, the LAN or computer system that will be distributed over different regions interconnect, and reach resource-sharing
Purpose.If internet (Internet) is wide area network maximum in world wide.Specifically, wide area network is by many group of switches
Into using the connection of point-to-point between interchanger.Almost all of point to point link mode may serve to establish wide area
Net, including leased line, optical fiber, microwave, satellite channel.
Product is accelerated by wide area network, the branch of user and affiliate no matter in which corner of the earth,
Can be easy acceleration its important application program and data, obtain on a wide area network approximate LAN application access
Impression.
In the prior art, in broad terms, common wide area network accelerates product mainly to include two categories below：
(1) traditional CDN (Content Delivery Network, content distributing network) technology
CDN technologies take full advantage of the machine for being deployed in all parts of the world, have given full play to the advantage of multinode, have passed through intelligence
The technology such as protocol optimization realizes the optimization of transmission between route, node, can have to the application using http protocol and accelerate effect well
Fruit.However, traditional CDN technologies only have acceleration effect to HTTP/HTTPS agreements.In actual WAN network, except
Outside HTTP/HTTPS agreements, also a lot of other application protocols and some proprietary protocols, and traditional CDN technologies then can not be right
These agreements have acceleration effect.
(2) wide area network acceleration equipment
The mode of deployment wide area network acceleration equipment can have acceleration effect to various application protocols and proprietary protocol.Specifically
Ground, unilateral acceleration is realized by being deployed in source station, or bilateral acceleration is realized by being deployed in source station and client.
But if if only in source station, deployment facility does unilateral acceleration, the effect of acceleration is limited, has no idea to pass through equipment
Between proprietary protocol do corresponding optimization；If doing bilateral acceleration, then need in the corresponding equipment of client export deployment.
The scene that concentration is compared accessing user in enterprise application in bilateral acceleration is more applicable, but the application more dispersed to client
Scene can not be then applicable.Such as, when the user of access is the netizen in the whole world, it is impossible to all dispose corresponding equipment in client.
No matter in addition, unilateral acceleration or bilateral acceleration, the mode of this deployment acceleration equipment is compared with CDN technologies, all
Do not utilize global node to realize intelligent route selection, do not play the advantage of intelligent route selection technology.
It should be noted that TCP and UDP are transport layer protocols, TCP is stream-oriented agreement, and UDP is datagram-oriented
Agreement.TCP and UDP advantage and disadvantage difference is as follows：
The advantages of TCP, is reliable for transmission, can ensure the correctness and order of data transfer；Shortcoming be network it is poor or
When person transmits small data, efficiency of transmission is low.
The advantages of UDP is that efficiency of transmission is high in network difference or transmission small data；Shortcoming is unreliable to transmit, may
Meeting packet loss, it is impossible to ensure the order of arrival of transmission data.
In summary, wide area network of the prior art accelerates product certain deficiency to be present, therefore needs to provide one kind newly
The wide area network acceleration system of type, to meet use in practice.

S6。
Step S6, present node server judges that next-hop is client source station or node server；If client source station,
It is transferred to step S7；If node server, step S8 is transferred to.
Step S7, data to client source station, the flow that present node server forwarding client is sent terminates.
Step S8, the IP of client source station and port information are sent to down by present node server by proprietary protocol device
One node server, by transmit data-optimized device to client transmission come data optimize, and be sent to next
Individual node server, it is transferred to step S1.
Correspondingly, when client source station sends data to client, then above-mentioned client to node server, node are passed through
Server carries out backtracking to node server, node server to client source station path, so as to transmit data to client
End.Equally, when data are transmitted to client in client distal end, still transmission data optimization technique can be used to carry out data
Optimization, to lift transmission speed.
Wherein, in an optimal path, line number is entered using TCP or udp protocol according to network condition between node server
According to transmission.This in same path in the prior art with being only capable of carrying out data transmission distinguishing using single Transmission Control Protocol or udp protocol
The present invention can use TCP and udp protocol simultaneously on same optimal path.Specifically, on optimal path, compare in network
Transmission Control Protocol is used between good node server, udp protocol is used between the poor node of network, so as to make full use of network
Transmission performance, further improve efficiency of transmission.
In summary, wide area network acceleration system and method for the invention based on TCP/UDP can pass through Intelligent routing, section
The technology such as protocol optimization realizes the optimization of transmission between point, can accelerate effect to being produced based on the various application protocols of TCP/UDP agreements
Fruit；It is equally applicable to the more scattered application scenarios of client.So the present invention effectively overcome it is of the prior art it is a variety of lack
Put and have high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
