Fig. 2 is the configuration diagram according to the Novel hot disaster tolerance network architecture of at least one embodiment of the application.Fig. 2 only schematically shows three service nodes 210.But those skilled in the art can know, and in actual applications, can use a large amount of service node 210, such as, but not limited to, hundreds of is several thousand nodes 210 even.Node 210 can be in the bank service site outlet, ATM atm device, client's self-inquiry terminal equipment, send cabinet etc.Wherein, all be equipped with corresponding WAN router for each node 210 in a plurality of service nodes, be used for connecting special line 215.It should be noted that at least unlike the prior art be that 210 of each nodes are equipped with wall scroll special lines 215.Special line 215 can be this area special line commonly used, such as, MSTP (based on the multi-service transport platform of SDH), CE(Carrier Ethernet).
Each node 210 by its corresponding to WAN router, use the wall scroll special line 215 access carrier networks 220 corresponding with this node, in two layers of transmission network pattern of carrier network 220 place's configuration " Y " types, bifurcated routes to corresponding operator's transmission equipment thus, and and then the operator's transmission equipment (not shown) by correspondence be coupled to two aggregation networks equipment 230 in the wide area network convergence-level, that is: data center's convergence device 230-1 and the convergence device 230-2 of Disaster Preparation Center on respectively.Carrier network can be the various access bearer networks of commonly using, such as, but not limited to, the access network that is provided by operators such as China Telecom or China Mobile.Node 210 access network used can be any type of access device, as the low end router of Cisco, H3C, the StarNet, Maipu.Wide area network aggregation networks equipment 230 can be any type of convergence device: as the middle and high end switch of Cisco, H3C, the StarNet, Maipu.Wherein, each service node 210 is by its special line 215 and two layers of transmission network pattern of Y type, can communicate with the wide area network aggregation networks equipment 230-1 of data center and the wide area network aggregation networks equipment 230-2 of Disaster Preparation Center simultaneously, rather than a time only communicates by letter with one of them.
Wide area network aggregation networks equipment 230 and then be connected to respectively data center server (or server cluster in the data center systems local area network (LAN) by the nucleus equipment 240 in the wide area network core layer, below these two concepts be used interchangeably) 250 and Disaster Preparation Center's system local area network in Disaster Preparation Center's server (or server cluster, below these two concepts be used interchangeably) 260.Particularly, the convergence device 230-1 of data center is connected to data center's core network system, and more specifically be connected to wherein data center server 250, the convergence device 230-2 of Disaster Preparation Center is connected to Disaster Preparation Center's core network system, and more specifically is connected to Disaster Preparation Center's server 260 wherein.Data center server 250 and Disaster Preparation Center's server 260 are in full accord aspect function, data, the service that provides.Simultaneously, data center and Disaster Preparation Center is interconnected by high bandwidth special line 270 on the wide area network core layer, with the disaster tolerance function between providing mutually.Therefore, data center server 250 and Disaster Preparation Center's server 260 can be active and standby each other.Although for the sake of clarity server 250 is called data center server in this application, server 260 is called Disaster Preparation Center's server, but do not carry out in actual applications specific differentiation, for service node 210, server 250(or 260) can be that data center server can be also Disaster Preparation Center's server.
Can be seen by Fig. 2, an embodiment according to the application, how on earth do not consider the setting of carrier network 220, as long as according to two layers of transmission network pattern of Y type architecture configuration, just can make single service node 210 via its WAN router only the convergence device 230-1(of data center by being coupled to correspondence on wall scroll special line 215 so that be connected to data center server 250) and the convergence device 230-2(of Disaster Preparation Center so be connected to Disaster Preparation Center's server 260).Thus, realized the network architecture of " Y " type, reduced the quantitative requirement to special line 215 at service node 210 places, that is, accessed respectively a node from two common special lines and be reduced to and only need the wall scroll special line.Make the network configuration below the wide area network convergence-level be simplified, improved the utilance of whole framework, and reduced the load of aggregation networks equipment.
Further, another embodiment according to the application, when needing to upgrade after the wide area network architecture laying is completed, for example from traditional cold standby, hot standby to dual-active, when the standby pattern of the calamity of living is upgraded more, do not need to increase the special line quantity that is coupled to carrier network 220 on existing single service node 210, that is, still only use an existing special line 215 between them.And only need to set up more multi-group data center or Disaster Preparation Center's architectural framework on wide area network convergence-level and wide area network core layer mirror image, make the wide area network core network device that is arranged in the same area be connected with the corresponding aggregation networks equipment in this zone, then by further disperseing transmission mode in carrier network 220 places configuration, and by the routing management on convergence-level, just the data Replica from service node 210 places can be backuped to data center or the Disaster Preparation Center that newly establishes.Thus, realized single service node is extended for by being coupled to more than one data center or Disaster Preparation Center on the wall scroll special line, such as but not limited to, on be coupled to two or more (three, four, etc.) data center or on be coupled to the center how alive of two or more (three, four, etc.).Thus, the upgrading of the standby pattern of calamity will can not increase service node special line quantity, realize dilatancy cheaply.
Fig. 3 is the framework method flow chart according to the Novel hot disaster tolerance network architecture of at least one embodiment of the application.In step 310, build " Y " type network architecture as shown in Figure 2 on service node and aggregation networks equipment, build the data center of complete mirror image/Disaster Preparation Center's wide area network architecture, and the wide area network core layer of data center and Disaster Preparation Center is interconnected by the high bandwidth special line.In step 320, use the dynamic routing technology to carry out intercommunication in equipment in wide area network core layer and wide area network convergence-level, typical dynamic routing technology comprises, such as but not limited to, ospf (Open Shortest Path First, OSPF) agreement and or road information protocol (Routing Information Protocol, RIP), etc.In step 330, be used for " Y " type special line transmission network pattern of each service node in Virtual network operator place's configuration.in step 340, when each service node uses " Y " type special line with data communication during to the data center of the first line of a couplet and Disaster Preparation Center, the place uses link detecting and floating static router in the wide area network convergence-level, the difference of pointing to destination network segment by route realizes the shunting to data: if service node is intended to communicate by letter with data center, (for example directly data are routed to the aggregation networks equipment of data center, the wide area network aggregation networks equipment that is used for data center), if service node is intended to communicate by letter with other service node, or be intended to communicate by letter with Disaster Preparation Center, (for example data are routed to the aggregation networks equipment of Disaster Preparation Center, the wide area network aggregation networks equipment that is used for Disaster Preparation Center).
An embodiment according to the application, the network equipment in wide area network convergence-level and the place's use of wide area network core layer does not need to customize especially, so long as can support convergence device or the core layer equipment of link measuring ability, can access " Y " type network architecture of the application.Thus, greatly improve the compatibility of " Y " type network architecture, can directly apply to present most of convergence-level and the core layer equipment used, need not further device upgrade.
Another embodiment according to the application, aggregation networks equipment place in the wide area network convergence-level, periodically (as per second 1-3 time) each service node is carried out link detecting, and be combined with the floating static router technology, automatically and in real time issue and to reach route, delete unreachable route, realize the real-time switching of the convergence device of the communication link that breaks down or fault and remove; Meanwhile, the service node WAN router also detects with two wide area network convergence routers of same period (as per second 1-3 time) to the link upper end, if one of them convergence router has fault, can automatically route handoff be arrived another convergence router, thereby guarantee the consistency of route.
The embodiment that also has according to the application, full symmetric due to " Y " type network architecture of disposing, by checking the cost value (overhead value) of every route on the wide area network core layer, can judge the state of every link in " Y " type network architecture and the symmetry of every link, needn't carry out inspection on each aggregation networks equipment thus, improve detection efficiency.For example, at first be the wide area network nucleus equipment (such as, switch) to each aggregation networks equipment (such as, convergence router) a different double-digit cost value is set, can distinguishes the route of a certain service node by which aggregation networks equipment issue by the routing table of wide area network core; Then a three-figure cost value is set between the wide area network nucleus equipment of data center and Disaster Preparation Center; Data center's wide area network core is acquired the route of two same network segments by dynamic routing protocol, select little (the double-digit cost) of cost value to enter routing table; If have large (three-figure cost) route of cost value in any wide area network kernel route table, illustrate to have asymmetric route in network.In the network environment of aggregation networks equipment more (double-digit cost can support 1-99 aggregation networks equipment), by the said method asymmetric point in fixer network rapidly, namely produce the aggregation networks equipment of asymmetric route.This characteristic can detect the validity of the standby network of calamity in real time, and need not to detect by drilling.
If necessary at each service node 210(Fig. 2) locate to consider node redundancy, can build two " Y " type network configurations.Fig. 4 is the configuration diagram according to two " Y " type network architectures of at least one embodiment of the application.Each service node can have the backup node of host node and redundancy.Host node and backup node are all by being linked to data center and Disaster Preparation Center separately on " Y " type network architecture.Thus, realized the network configuration of two " Y " types.Each data center or Disaster Preparation Center can be positioned on different geographical position, and it is interconnected to use the high bandwidth special line to carry out looped network between these data centers and Disaster Preparation Center, thereby have greatly increased redundancy and the reliability of the network architecture.
