Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of route selecting method based on strategy.
Background technology
Strategy of the present invention comprises the current service traffics in service priority, the network, the bandwidth resources situation of network and the contents such as rule of permission or restricted circulation, and these strategies are used widely in network communications technology field.
Along with the continuous expansion of internet (Internet) scale, various network services are fallen over each other to emerge in large numbers, and advanced multimedia system also emerges in an endless stream.Because real time business is comparatively responsive to characteristics such as network transfer delay, delay jitters, therefore, when sudden high file transfer (FTP) being arranged on the network or contain the business such as hypertext transmission (HTTP) of image file, real time business will be subjected to very big influence; In addition, because multimedia service will take a large amount of bandwidth, so also will make and need guaranteed key business to be difficult to be transmitted reliably in the existing network.So, to be transmitted reliably for guaranteeing key business, various service quality (QoS, Quality of Service) technology is just arisen at the historic moment.The Internet engineering duty group (IETF, Internet Engineering Task Force) has proposed a lot of service models and mechanism, to satisfy the demand of QoS.What industry was relatively approved at present is to use integrated service (Int-Serv, Integrated Service) model at the access or the edge of network, uses differentiated service (Diff-Serv, Differentiated Service) model at server.
The Diff-Serv model only ensures QoS by the measure of setting priority level, though this model has the high characteristics of line efficiency, but concrete effect is difficult to prediction, therefore, industry is that the Diff-Serv model of backbone network has been introduced an independently bearer control layer, set up the special Diff-Serv qos signaling mechanism of a cover, thereby set up a resource management layer specially, be used for the topological resource of supervising the network for the Diff-Serv network.This resource management Diff-Serv mode is called as the Diff-Serv of independent bearing control layer model.In this model, load network resource manager is responsible for configuration management rule and network topology, is client's service bandwidth application Resources allocation.The set of the all-router that each load network resource manager is managed is called a management domain of this load network resource manager, transmit client's service bandwidth application request and result between the load network resource manager of each management domain by signaling, and the routing information that distributed for professional application of load network resource manager etc.Introduce load network resource manager in the prior art below and carry out the method for route selection.
Prior art one:
Mode with static routing (Static Routing) is determined the path.This kind mode is to determine in the route method a kind ofly, and static routing is meant in case node has been determined its routing table, and the route of this node will no longer change.Use this method must satisfy a potential hypothesis: the condition that routing table is formulated in influence is constant.Calculating under the situation of transmission cost according to the data rate between distance and intermediate node, this hypothesis is effectively sometimes, and its reason is, capital equipment upgrading only or equipment migration, otherwise these parameters can not change.Therefore, in some cases, static routing is desirable, such as, company can static defining be a route to security server to the connection of Internet, and the authentication mechanism that provides through server does not allow any access, in such cases, can improve the fail safe of network by the configuring static route.But static routing can only be worked under the constant situation of network condition with flying colors, and this is normally impossible in the reality; Even more important a bit is, adopt this static routing technology, can't realize carrying out strategy path selecting according to for example factors such as service priority, source destination address and current network flow, thereby cause the specific (special) requirements that to satisfy some routings, thereby also just can't ensure the service quality that these are professional.
Prior art two:
Figure 1 shows that the Diff-Serv model scheme of independent bearing control layer, in the key experimental network of service (QBone), adopted bandwidth broker device model.As seen from Figure 1, Internet has defined the corresponding bandwidth proxy server for each Diff-Serv management domain specially, the bandwidth broker device is responsible for handling from subscriber's main station, perhaps service server, perhaps please ask in network maintenance staff's the bandwidth, the bandwidth broker device determines whether to allow user's bandwidth application according to the resource reservation situation of current network and configured strategy and the business (SLA) signed with the user; Also comprise service server in this model, belong to service control layer, can realize functions such as soft switch; And each router that belongs to bearer network.Management domain of the corresponding management of each bandwidth broker device can carry out communication between each bandwidth broker device.
Referring to Fig. 2, each Bandwidth Broker inside comprises: user traffic interfaces is used for carrying out two-way communication with service server, main frame/user and network operation; The territory interface is used for carrying out communication with the bandwidth broker device in other territory; The territory inner joint is used for the router in the control and management territory; Also comprise database, simple strategy service module, routing iinformation module, network management interface and policy interface; In Bandwidth Broker, record a large amount of static state and the multidate information of the configuration information of the topology information that comprises all kinds of SLA configuration informations, physical network, router and policy information, user authentication information, current resource obligate information, network seizure condition information etc., simultaneously, Bandwidth Broker also records routing iinformation, in order to establish user service flow path and cross-domain downstream bandwidth manager position.
In the prior art, the bandwidth broker device on the bearer control layer is basically to the process of setting up of the route in the bearer network layer, just according to the routing table computing service request of each router the path of process.Therefore, in case the information on each router in territory has renewal, for example carry out new professional or professional upgrade etc., the bandwidth broker device on the bearer control layer also will upgrade thereupon, may cause the instability of network reservation like this; And Bandwidth Broker needs the dynamic routing information in minute book zone, has the frequent problem of routing table update, causes the instability of network reservation easily; Even more important a bit is, the bandwidth broker device can't be realized carrying out strategy path selecting according to for example service priority, source address and destination address and current factors such as network traffics, thereby can't satisfy some special routing needs, also just be difficult to satisfy the quality of service requirement of the pairing business of these routings.
In the prior art, also there is routing scheme in multiple other territory that comprises the Rich QoS scheme that other operators provide, though these schemes have simple tactful route implementing mechanism, the complicated network structure, the construction cost height is difficult to adapt to the needs of large scale network.
