Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in accompanying drawing 1,2, the invention discloses a kind of cloud group virtual flow-line system and its implementation;
Current cloud develops comparative maturity, the present invention proposes the private server pond setting up oneself in multiple cloud provider, the proprietary route service that the thought that the data communication that server pools on these different clouds forms oneself connects builds real-time data is called for short cloud group, thus the time delay that the network congestion effectively avoiding employing ISP default route to cause and more network hops cause.Had a large amount of Internet Service Providers to provide cloud service at present, Cloud Server resource almost spreads all over the entrance of most of ISP and is often implemented in backbone network.Because backbone network has a large amount of bandwidth, so build transmission network by Cloud Server and provide proprietary route service for real-time data, and communication terminal selects forwarding server to access transmission network nearby, can from avoiding congested, minimizing delay to a great extent.
As shown in Figure 1, the cloud group virtual flow-line system that the present invention proposes primarily of network management unit, Cloud Server pond, forwarding server and communication terminal composition, wherein network management unit, Cloud Server pond, forwarding server etc. jointly composition cloud group virtual flow-line service subsystem provide service for communication terminal.Wherein, network management unit is responsible for the management, scheduling of resource, session management, terminal management, transmission network structure etc. of whole system; Cloud Server pond is the set of each managed server resource of Yun Qunzhong; Forwarding server, for building routing forwarding network, be network management unit is that each BlueDrama is selected and the server resource disposed separately from Cloud Server pond, is responsible for the structure of virtual routing tables, terminal registration and data retransmission; Communication terminal is the service object of the proprietary route service of this system, its proprietary route service provided by the use system that initiates a session request to network management unit.
The proprietary route service that communication terminal will use system to provide, needs through following three steps:
1. the structure of session transmission network
Network management unit needs for each BlueDrama safeguards a transmission network, the server resource in scheduling on demand cloud group;
(1) network management unit selects suitable forwarding server to dispose according to the session request of communication terminal from Cloud Server pond.The deployment of forwarding server can complete in three ways, i.e. static deployment, Dynamical Deployment and static deployment and Dynamical Deployment combine.
A. static deployment way, namely network management unit selects forwarding server by manual intervention (according to the position of service object, the connecting object of precognition, resource requirement) or the mode of Stochastic choice from Cloud Server pond, mainly be applicable to the occasion that service object relatively fixes, dispose than the Cloud Server scheduling of resource being easier to realize optimizing in like fashion and reserve;
B. Dynamical Deployment mode, namely detects the position of communication terminal dynamically, and from Cloud Server pond, selects forwarding server according to positional information nearby.The mode that the position of communication terminal initiatively can be reported by communication terminal is determined, information (as source IP address) when also can be connected by communication terminal is determined, this mode is applicable to the random situation of service object's location comparison, but to the scheduling of Cloud Server resource and reserved require higher;
C. the mode that combines of Static and dynamic, namely realizes the optimization between the reasonability of cloud service scheduling of resource and communication terminal locational uncertainty by the combination of above two kinds of modes.
(2) dispose after forwarding server as required and under the intervention of network management unit, connect other forwarding servers and build transmission network, build the routing table of point-to-point (clean culture) and/or the routing table of point-to-multipoint (multicast) according to session demand.
2. communication terminal adds transmission network
(1) communication terminal connection transmission network administrative unit initiates a session request, and obtains the information such as position, bandwidth, resource of forwarding server list and corresponding forwarding server;
(2) communication terminal selects a forwarding server as first-selected connection server nearby according to information such as position, time delay, distance, resources from forwarding server list;
(3) communication terminal adds transmission network to first-selected connection server initiation connection;
(4) forwarding server to the information of communication terminal carry out registration and and other forwarding server share, build virtual routing tables.
3. data input and data output
The transmission of data and reception adopt the mode of tunnel encapsulation to carry out.
(1) when sources traffic terminal needs to send data, first encapsulation of data add the metadata information such as former communication terminal and object communication terminal;
(2) sources traffic terminal sends to its forwarding server connected the data after encapsulation;
(3) forwarding server searches converting route according to metadata information (as object communication terminal), and according to routing iinformation forwarding data to next forwarding server, or directly send to object communication terminal;
(4) object communication terminal receives the packet after encapsulation, rejects metadata and therefrom parses initial data.
Applicating example:
As shown in Figure 2, by the X1 Cloud Server pond be placed in different cloud service provider, X2 Cloud Server pond, X3 Cloud Server pond, forms privately owned cloud group.
Communication terminal 1 will carry out exchanges data with communication terminal 2.If directly communicated by the Internet, speed will be subject to very large impact.
Utilize the network management unit in cloud group, carry out link analysis, the speed that testing communication terminal and Servers-all pond link and stability, determine optimum connection.Suppose that communication terminal 1 is connected optimum with X1 Cloud Server pond, communication terminal 2 is connected to X3 Cloud Server pond and connects optimum, then optimal scheme communication path.
" communication terminal 1 " sends data in " X1 Cloud Server pond ", and data retransmission is to " X3 Cloud Server pond ", and data are sent to again " communication terminal 2 ".
By adopting technique scheme disclosed by the invention, obtain effect useful as follows:
Cloud group virtual flow-line system of the present invention and its implementation, avoid to greatest extent Internet data transmission congested, reduce data transfer delay.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should look protection scope of the present invention.
