Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method of in empty switching domain, carrying out automatic routing.
Background technology
Along with the continuous increase of Internet scale, various network services are fallen over each other to emerge in large numbers, and advanced multimedia system emerges in an endless stream.Because real time business is comparatively responsive to characteristics such as network transfer delay, delay jitters, when sudden high FTP being arranged on the network or contain the business such as HTTP of image file, real time business will be subjected to very big influence; On the other hand, multimedia service a large amount of bandwidth that accounted for, like this, the key business that existing network need guarantee just is difficult to be transmitted reliably.So various QoS technology are arisen at the historic moment.IETF has advised a lot of service models and mechanism, to satisfy the demand of QoS.
Wherein, multiple application and service and broadband multimedia services based on door, being included as the ordinary residence user provides the online game of abundant Video/Audio stream, VOD (video request program), video multicast, multimedia interactive, high bandwidth requirements, for the business user provides video conference, long-distance education, VPN, has Leased line that QoS ensures, IP Hotel etc., become the important content of broadband operation.
Operator and the user of enterprises and institutions have the higher degree of awareness to ethernet technology and end-to-end ethernet technology.Ethernet technology becomes one of major technique of building unification of three nets, metropolitan area network future, and Ethernet service will have great development space; At these users, the VPN/VPDN special line scheme of multiple modes such as V-Switch, GRE, L2TP, MPLS has been proposed.
The empty exchange of intelligence (intelligent V-switch) technology is mainly used in to set up to be stablized; practical; economic operation level Metro Ethernet; can realize that QoS guarantees; network security protection; functions such as carrier-class network operation and management; possesses user management based on number; certain mobility; the core business managerial abilities such as centralized management that professional open management is chargeed; provide and comprise intelligent two laminar flow amounts scheduling; the LAN special line; professional and service such as IP flow planning; the present deficiency of network on pure two layers of ability filled up in its appearance, and the construction of new period metropolitan area network is had important effect.
The V-Switch system is different from above-mentioned traditional technology, and the notion of its inlet port VLAN adopts the VLAN exchange, and networking is simple and practical.
As shown in Figure 1, the logical level and the functional mode figure of V-Switch system have been provided.It comprises: service control layer, connection key-course and bearing capacity layer.By described three-decker, described V-Switch system possesses perfect ethernet vlan exchange and scheduling feature, the means of service dispatching and foundation, adjustment flexibly, and abundant and extendible two layer service providing capabilities, perfect oam instrument and information.
As shown in Figure 2, be the networking schematic diagram of V-switch system.VSC is positioned at bearer control layer, and passes through the RCIP protocol interface between service control layer and other VSC, and passes through the COPS+ protocol interface between the logical bearers net.
Can realize the V-Switch distributed computing technology by described V-switch networking schematic diagram:
(1), professional control register technique: the user is engaged in registering in the enterprising industry of SCR by dynamic or static mode according to actual needs.SCR has write down user data, comprises physical location, authority, charging authentication, interface capability information etc., notifies SCR or initiatively carry out associative operations such as resource bid, modification, release to VSC by SCR when customer call.
(2), the V-Switch control technology: exchange resource in the maintaining network, comprise equipment, interface, link, VLAN, be that Business Stream selects service path, distributes the Vlan resource, reclaims operations such as resource.Sequence of operations such as the required resource bid of carrying out of user, release, modification all need to be issued to DRE (Date Relay Entity by explorer; Data Relay Entity) on the equipment.VSC bears functions such as the establishment of connection of VLAN exchange end to end, maintenance, dismounting, CDR generation as the bearer control layer in the intelligent virtual exchange system structure, is the control nerve of V-Switch system.
(3), VLAN switching technology: be responsible for the resource control information that issues according to VSC by DRE, carry out the forwarding of actual Ethernet service stream.Need simultaneously the change in resources information of this equipment is reported VSC equipment.
The technical scheme of prior art one related to the present invention is to determine service path by the method for static routing (staticRouting), has determined a node in case it is meant, the routing table of this node of static defining then, and this node will no longer change.In other words, most economical route is not according to the time.
In the process of implementing static routing, node need not to repeat routing algorithm, therefore at the networking initial stage, under the very little situation of network size, static routing is the most effective routing mechanism, and it does not consume any bandwidth and finds route or communicate with other routers, realizes fairly simple.
Yet the condition that need suppose to influence the formulation of table by said method is constant.This hypothesis is effectively sometimes, because cost normally calculates according to the data rate between distance and intermediate node.Capital equipment upgrading only and equipment migration, otherwise these parameters are constant.
In fact, the communication flows of every network link always changes along with the variation of time, and network node also might break down.Along with the variation of network state, original excellent route may become very bad route.Condition is changed slow in reacting, just become the shortcoming of static routing maximum.And, arrive the appearance of destination redundant path along with the increase of network, use the workload of static routing can become big.Any variation of transmission line availability must manual be found and will be programmed to route in router or the wide area network.The characteristics of wide area network are that topology is complicated, provide many possible paths, this situation absolute demand dynamic routing.In wide area network complexity, that have multipath, use static routing, the purpose of route redundancy is destroyed.
Just because of this, so adopt dynamic pathfinding mode usually, the technical scheme that the prior art relevant two promptly occurred with the present invention, it adopts hop-by-hop route thought among the IP to realize Vswitch to connect routing mechanism in the territory of each VSC in the key-course, and its basic thought is:
Be each DRE configuration service route in the territory, VSC is routing table of each DRE simulation, carry out route for each input grouping independently, routing iinformation can pass through user's static configuration, also can dynamically obtain, VSC uses this algorithm to select the VLAN interface resource that bearer service connects in the territory as bearing bed in the process of carrying out professional route, be professional routed path (may also be referred to as the carrying routed path), concrete performing step is as follows:
Step 1, for initial VSC, find inlet DRE according to calling number, the DRE information that will enter the mouth adds has searched during DRE gathers, simultaneously user entry VLAN interface information is noted.
The a certain VLAN interface of step 2, selection joint access DRE.Can select at random, also can select according to activating conditions such as situation, route priority, bandwidth demand as station address, VLAN interface.
Step 3, judge whether the other end DRE of this VLAN interface is the called outlet DRE in this territory, if then search and finish; If not, then continue execution in step 4.
Step 4, write down the other end DRE of this VLAN interface, and check whether this DRE has added in the set, in this way, then abandons this time searching, and gets back to step 2; If no, be starting point then with this DRE, select all VLAN interfaces of contiguous DRE, repeating step 2 then.
By the technical scheme of above-mentioned prior art two as can be seen, there is following defective in it:
The route one by one that technique scheme adopts need be routing table of each DRE node maintenance, for bigger VSC management domain, its DRE that administers may be a lot, and therefore the routing table of required maintenance will be big especially, thereby cause routing table look-up speed slower, be not easy to Operation and Maintenance.
