The network low-load self-configuration router facing to the content delivery/subscription has a simple structure, and the network self-configuration module is added, so that the router can reduce network load and manual intervention, and meanwhile rationally utilize hardware resources.
Description
Technical field
The utility model relates to network router, especially, and the low load of specifically a kind of network, self-configuring router towards content release/subscription service.
Background technology
At present, along with broad application of Internet and fast development, great change has appearred in APPLICATION OF A DISTRIBUTED SYSTEM scope and scale, and one of marked change that it brings is being widely used of large-scale information issuing system.The publish/subscribe traffic model can satisfy the needs that Internet goes up the loose communication of large-scale application system well owing to have asynchronous, multi-point, and it is the foundation stone that makes up large-scale distributed system.
How to select correct router, incident and subscription condition are sent to distribution agency and the subscriber who needs, just become a very important problem, even we can say, this is the matter of utmost importance of all distributed post/ordering systems.
In most of existing researchs; In order to improve the efficient of router operation; People are organized into a kind of tree or acyclic graph structures with event agent's topology of networks usually; Corresponding content-based router can be the basis with this given topological structure, adopts certain strategy to carry out forwards efficiently.But, the fault-tolerant ability of this router a little less than, the wherein failure on any one node or limit all may become several disconnected subnets with whole network division.Simultaneously, in network, increase at every turn or delete one when acting on behalf of, all will cause very complicated system's reprovision work.
Summary of the invention
The purpose of the utility model is to provide the low load of a kind of network towards content release/subscription service, self-configuring router; With the network efficiency that improves the forwarding of publish/subscribe Service events, network efficiency, the fault-tolerant ability of subscribing to maintenance, realize the low distribution of load and the self-configuring route of network.
The technical scheme of the utility model is:
The low load of a kind of network, self-configuring router towards content release/subscription; It comprises route primary module, central control module, operating system module, aspect of network self-configuration policy module and data transmit-receive module; Described data transmit-receive module is as the signal transmitting and receiving end transmitting-receiving route data of router; Data transmit-receive module is beading process system module, central control module and route primary module successively, and described aspect of network self-configuration policy module links to each other with central control module.
The model of the aspect of network self-configuration policy module of the utility model is NSO001.01.
The beneficial effect of the utility model:
The utility model simple in structure, added the aspect of network self-configuration module, be a kind of router that rationally utilizes hardware resource when alleviating offered load and manual intervention.
The aspect of network self-configuration policy module of the utility model provides the LBRA-SC route technology of the minimum support self-configuring of a kind of load Network Based.The principle that the load Network Based of LBRA-SC route technology is minimum has been introduced the self-configuring strategy.It is described the topological structure of meshed network with the mode of adjacency list, through searching adjacency list, select the highest link transmission data of bandwidth, maximum possible avoided network congestion.Accomplished when node failure simultaneously or add fashionablely, network is the function of reorganization automatically.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Fig. 2 is the adjacency list of the example endpoint network topology structure of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the router that adopts in a kind of distributed post/ordering system has route primary module 1, central control module 2, aspect of network self-configuration policy module 3, operating system module 4,5 five modules of data transmit-receive module successively.Wherein route primary module 1 is with aspect of network self-configuration policy module 3 and connect central control module 2, and central control module 2 is connected to operating system module 4, and operating system module is connected on the data transmit-receive module 5.
(1) route primary module
The route primary module mainly plays the effect of overall situation control, coordinates each module through central control module 2 simultaneously.
(2) central control module
Central control module plays safeguards an access control chain table function, according to someway, prevents that the disabled user from destroying router.
(3) aspect of network self-configuration policy module
The aspect of network self-configuration policy module provides distributed post/ordering system network configuration rule set.
(4) operating system module
Commercial embedded OS module.
(5) data transmit-receive module
The function of data transmit-receive module is, the packet of transmitting as needs arrives router and waken up, the visit data bag, and the inquiry route is revised route data corresponding in the packet, transmits packet.
During practical implementation:
In distributed post/subscription service; Be formed by connecting according to certain topological structure plurality of nodes, wherein, each node is equivalent to a centralized publish/subscribe system; Both by a distribution acting server, several publishers and several subscribers formed.For a node, the distribution agency under itself, publisher and subscriber are called this locality, and for other nodes, then are called the strange land with respect to this node.For the router that adopts in the utility model, each node can be formed any topological structure according to non-directed graph.In the aspect of network self-configuration policy module, for the network topology structure of node, intend and adopt the mode of adjacency list to describe, show like Fig. 2.Wherein, BandWidth_n1_n2 representes the current bandwidth of the link from node n1 to node n2, and its value can record with the network traffics monitoring of software.
The incident or the condition of the subscription repeating process of aspect of network self-configuration policy module design are following:
1, after an incident or subscription condition are published, with the MI-MSNR technology it is mated in this locality.
2, if all and local adjacent node are then searched in the coupling failure in this locality in adjacency list, choose the link that wherein bandwidth is the highest and send to certain adjacent node to this incident or subscription condition, adjacent node then returns matching result and gives local if mate successfully; Otherwise then the local coupling of notice is unsuccessful.
3, if transmit for the first time and still mate successfully, then choose the high node of bandwidth link second, the process of repetition 2 and 3 is up to mating successfully or all and the adjacent node in this locality were all transmitted this incident or subscription condition.
4, if does not still mate successfully 3 end backs, then from the adjacent node of this locality, repeat 1,2,3 process, all nodes had all been transmitted this incident or subscription condition in coupling success or network.Repeating process finishes.
5, behind one or more node failures in the distribution agency network; Or after a new node joins existing network; Whole system can be carried out necessary adjustment and not need artificial reorganization network topology structure new network configuration automatically, is the self-configuring strategy of publish/subscribe system
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
