Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.It should be appreciated that the specific embodiments described herein are only used to explain the present invention, it is not used to
Limit the present invention.
As shown in attached drawing 1,2, the invention discloses a kind of cloud group virtual flow-line system and its implementation；
Comparative maturity, the present invention propose to establish the Special clothes of oneself in multiple cloud providers for current cloud development
It is engaged in device pond, the server pools on these different clouds form the thought of the data communication connection of oneself to build the special of real-time data
There is route service abbreviation cloud group, so as to effectively avoid using network congestion caused by ISP default routes and more network
Delay caused by hop count.There is substantial amounts of Internet Service Provider to provide cloud service at present, Cloud Server resource is almost spread over
The entrance of most of ISP and often it is implemented in core network.Since backbone network possesses substantial amounts of bandwidth, then pass through cloud service
Device structure forwarding network provides proprietary route service for real-time data, and communication terminal selects forwarding server to access nearby
Forward network, can from largely avoid congestion, reduce delay.
As shown in Figure 1, cloud group virtual flow-line system proposed by the present invention mainly by network management unit, Cloud Server pond,
Forwarding server and communication terminal composition, wherein network management unit, Cloud Server pond, forwarding server etc. collectively constitute Yun Qun
Virtual flow-line service subsystem provides service for communication terminal.Wherein, network management unit is responsible for the management of whole system, resource
Scheduling, session management, terminal management, forwarding network struction etc.；Cloud Server pond is each managed service device of Yun Qunzhong
The set of resource；Forwarding server be network management unit is each BlueDrama from cloud for building routing forwarding network
The server resource for individually selecting and disposing in server pools is responsible for structure, terminal registration and the data forwarding of virtual routing tables；
Communication terminal is the service object of the proprietary route service of the system, by initiating a session request to network management unit using system
The proprietary route service that system provides.
Communication terminal will use the proprietary route service that system provides, it is necessary to by following three steps：
1. session forwards the structure of network
Network management unit needs to safeguard a forwarding network, the service in scheduling on demand cloud group for each BlueDrama
Device resource；
(1) network management unit selects suitably forwarding service according to the session request of communication terminal from Cloud Server pond
Device is disposed.The deployment of forwarding server can be completed in a manner of three kinds, i.e., static deployment, Dynamical Deployment and static deployment
It is combined with Dynamical Deployment.
A. static deployment way, i.e. network management unit are by manual intervention (according to the position of service object, the company of precognition
Connect object, resource requirement) or randomly selected mode select forwarding server from Cloud Server pond, be primarily adapted for use in service pair
As more fixed occasion, deployment in this way is easier to realize the Cloud Server scheduling of resource of optimization and reserve；
B. Dynamical Deployment mode, the i.e. dynamically position of detection communication terminal, and according to location information from Cloud Server pond
In select forwarding server nearby.The position of communication terminal can communication terminal actively report by way of determine, can also
Information (such as source IP address) when being connected by communication terminal determines that this mode is suitble to service object position more random
Situation, but scheduling to Cloud Server resource and reserved more demanding；
C. the mode that static and dynamic is combined, i.e., realize cloud service scheduling of resource by the combination of both the above mode
Reasonability and communication terminal locational uncertainty between optimization.
(2) forwarding server after disposing connects other forwarding services on demand and under the intervention of network management unit
Device structure forwarding network, the routing of the routing table and/or point-to-multipoint (multicast) of point-to-point (unicast) is built according to session demand
Table.
2. communication terminal adds in forwarding network
(1) communication terminal connection forwarding network management unit initiates a session request, and obtains forwarding server list and phase
Answer the information such as position, bandwidth, the resource of forwarding server；
(2) communication terminal selects one nearby from forwarding server list according to information such as position, delay, distance, resources
A forwarding server is as preferred Connection Service device；
(3) communication terminal initiates the connection addition forwarding network to preferred Connection Service device；
(4) forwarding server is registered the information of communication terminal and is shared with other forwarding servers, structure
Virtual routing tables.
3. data sending and reception
Sending and receiving for data is carried out by the way of tunnel encapsulation.
(1) when sources traffic terminal needs to send data, first encapsulation of data and plus former communication terminal and purpose communication eventually
The metadata informations such as end；
(2) sources traffic terminal gives its connected forwarding server the data sending after encapsulation；
(3) forwarding server searches converting route according to metadata information (such as purpose communication terminal), and according to routing
Information forwarding data to next forwarding server or are transmitted directly to purpose communication terminal；
(4) purpose communication terminal receives the data packet after encapsulation, rejects metadata and therefrom parses initial data.
Applicating example：
As shown in Fig. 2, by the X1 Cloud Servers pond being placed in different cloud service providers, X2 Cloud Servers pond, X3 cloud services
Device pond forms private clound group.
Communication terminal 1 will carry out data exchange with communication terminal 2.If directly communicated by internet, rate is just
It can be subject to very big influence.
Using the network management unit of Yun Qunzhong, link analysis is carried out, testing communication terminal is linked with Servers-all pond
Speed and stability, determine optimal connection.Assuming that communication terminal 1 is connected optimal with X1 Cloud Servers pond, communication terminal 2 connects
It is optimal to be connected to the connection of X3 Cloud Servers pond, then optimal scheme communication path.
" communication terminal 1 " is sent data in " X1 Cloud Servers pond ", and data forwarding to " X3 Cloud Servers pond ", send out again by data
It send to " communication terminal 2 ".
By using above-mentioned technical proposal disclosed by the invention, following beneficial effect has been obtained：
The cloud group's virtual flow-line system and its implementation of the present invention, avoids Internet data transmission and gathers around to greatest extent
Plug reduces data transfer delay.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
Depending on protection scope of the present invention.
