Comparing with the present technology, the utility model has the advantage of rapid intercommunication of south and north networks, meeting the requirement of shanghai majority high-end clients and pair doublewire IDC server trusteeship.
Description
Technical field
The utility model relates to telecommunications, Netcom, and UNICOM's three nets interconnect, and particularly the telecommunications network communications and liaison lead to the control device that three nets interconnect.
Background technology
The present situation of China's Mainland operator is that the north mainly is that Netcom is solely big at present, south mainly is that telecommunications is solely big, owing to the exchanging visit of the user between two networks all must be by ChinaNet-Backbone and the key platforms of CNC-Backbone two big cores, reason owing to history and common interest, bottleneck problem between the two big backbones exists always, and seriously influenced southern and northern user's service quality, the CDMA business of networking customer group of adding CHINAUNICOM is also very huge, because each tame telecommunications benefits of operators collision problem, the present situation that causes southern and northern user " to connect and obstructed; logical and not smooth ", and southern and northern internet exchanging visit traffic carrying capacity is very big, my company complies with trend of the market, in time release based on telecommunications, Netcom, the business platform that UNICOM's three nets interconnect is started north and south interworking service pattern.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of advantages of simplicity and high efficiency telecommunications network communications and liaison control device that logical three nets interconnect for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: the control device that logical three nets of telecommunications network communications and liaison interconnect, it is characterized in that, this device comprises communication network, Netcom's network, UNICOM's network, the telecommunications egress router, Netcom's egress router, UNICOM's egress router, first core switch, second core switch, first interface router, second interface router, described communication network is connected with the telecommunications egress router, described Netcom network is connected with the Netcom egress router, described UNICOM network is connected with the UNICOM egress router, described telecommunications egress router, Netcom's egress router, UNICOM's egress router respectively with first core switch, second core switch connects, described first core switch, second core switch respectively with first interface router, second interface router connects.
Compared with prior art, the utlity model has following advantage:
(1) prohibits in telecommunications and open under the situation of eBGP, realized the implementation method of the quick intercommunication of southern and northern network, satisfied the most of high-end customer in Shanghai and the needs of two-wire IDC trust server;
(2) satisfy the cdma security client of fast access trustship that dial up on the telephone at telecommunication server;
(3) provide the design philosophy of core redundancy.
Description of drawings
Fig. 1 is the structural representation of the control device that interconnects of logical three nets of the utility model telecommunications network communications and liaison.
Embodiment
As shown in Figure 1, the control device that logical three nets of the utility model telecommunications network communications and liaison interconnect, this device comprises communication network, Netcom's network, UNICOM's network, the telecommunications egress router, Netcom's egress router, UNICOM's egress router, first core switch, second core switch, first interface router, second interface router, described communication network is connected with the telecommunications egress router, described Netcom network is connected with the Netcom egress router, described UNICOM network is connected with the UNICOM egress router, described telecommunications egress router, Netcom's egress router, UNICOM's egress router respectively with first core switch, second core switch connects, described first core switch, second core switch respectively with first interface router, second interface router connects.
Two core switch all run two layers, participating in route, have not quickened the surface speed forwarding of packet.Reduce 1 simultaneously and jump, make the user have only double bounce just to go out in the dmtnet net, the hop that has reached network optimizes.
The Cisco4507 switch is not participating in the OSPF route.User ip is by heavily distributing subnets in the DMTNET territory at ospf.Access-layer router is in the configuring static default route, and by inserting 163 cisco3845 router default static, the default-information oringnate by ospf is put on couple in router cisco7304 and other access-layer routers.Adjust on flow load to two switch by arbitrary first line of a couplet interface configuration ip ospf cost value at access-layer router.
After 163 line interruption, how outflow is forwarded to cnc or unicom, by to issue orders:

After 20.101.23.101 ping was obstructed, its static routing disappeared.Point to the CNC route of floating so this moment and just be put into every router of Access Layer by ospf, make access-layer router still can converting flow to cnc or uninet
After the chinaNET link down, how to control the data packet flow of returning?
At first by heavily announcing identical ip, the prefix of equal length is to CNC or UNINET, secondly by following configuration (needing the CHINANET webmaster to do on its cisco GSR router)
ip?sla?monitor?1
type?echo?protocol?ipIcmpEcho?202.101.23.102

ip?route?21.5.144.0?255.255.255.0?20.101.23.102?name?dmtnet?track?1
When 20.101.23.102 ping was obstructed, its static routing disappeared automatically, and the relevant route in the bgp also can disappear so.Can acquire relevant bulletin route this moment from CNC and UNINET, and flow can be returned by CNC or UNINET.
Because RX-8 mainly offers IDC user and uses, receive that by iBGP the routing table in the each province and city of Netcom and UNICOM reaches the visit ip of China Netcom and selects Netcom's outlet, UNICOM's outlet is selected by visit CHINAUNICOM, default route is still pointed to chinanet, reaches the automatic selection of optimal path of routing traffic outgoing direction.
By identical IP block, China Telecom is announced in the IP address of same prefix length, China Netcom, and the eBGP neighbours of CHINAUNICOM influence inbound traffics.Outflow is accurately controlled by iBGP and PBR.
Connect the router of cnc, set up the iBGP neighborhood with two 7304 access-layer routers or more access-layer router, whole route table items that the China Netcom each province and city have just been arranged on such 7304 routers, and whole routing tables of the AS9800 of CHINAUNICOM, default route is from the dynamic acceptance of the router of chinane outlet, and the implementation method command statement is as follows:
