The IP telecom network will bear guaranteed telecom-level services, while the Internet will bear the traditional and free Internet.The RM (resource management server) concept is introduced into the bearer control layer, so as to realize management over regional network topology and resources. When receiving a request from the service platform for resources, the RM will decide, according to the regional network topology and resource usage, whether to accept the call, thus implementing CAC (Connection Admission Control). The QoS of the entire network can be guaranteed for cross-region services via coordination between RMs.The CMCC IP backbone network, which introduced in WCDMA stand, is an application to the concept of IPTN.Poster 3: The 5th Generation RouterAs we know, the router technology have past five generation.The first generation router based on fixed interface and centralized structure. All the work done by a central CPU. The second generation make the interface modularized, and it is more flexible then first generation. All these two kinds of routers have the same character, in one aspect that it is flexible for every thing done by CPU, which means that new feature can be easily added by software upgrading. On the other hand, for centralized structure, the performance can not be guaranteed. So, the third generation routers based on the distributed structure have one CPU in each service board. It improves the whole performance of the router.And then the forth generation router coming with ASIC technology have one ASIC chip in each service board and have more advanced performance than CPU because of its hardware. But just about its hardware, it is not flexible enough. Especially with the rapid development of IP technology, new service and features come one day after another. If the core router based on four generation, you have to change hardware when you want to add some new features and services such as MPLS, QOS and so on. Juniper is the spokesman of the 4th generation router. AS we all know, Many GSR from other vendors, if you need MPLS service, you have to replace the old line card with a new one, this will severely affect the service, and waste a lot of cost.The 5th Generation Router which use NP (network processor) to instead of the ASIC on the board. It has the advantage of both CPU and ASIC with good flexibility and high performance. You only need software upgrading for some new service, even from IPV4 to IPV6. Huaweis high-end routers all base on NP technology and Huawei has been the spokesman of the 5th generation router.Poster 4: Hierarchy of Provider Edge Device (HoPE)As we know, in the deployment of BGP/MPLS VPN, the PE(Provider Edge) device should maintain all the VPN routes of the VPNs which it belong to. If there are many VPNs attaching to a PE, and the capacity of PE is somewhat limited, then the bottleneck will be encountered.Another problem is that the current BGP/MPLS VPN model is something of a “Plane Model” where the demand of the performance of the PE device are all the same no matter which layer the PE device is belongs to. However, the typical network is Core-Convergence-Access(Edge) layered model, and the performance of the device is high in Core Layer and low in Access Layer, and the scale of network is large in Access Layer and small in Core Layer, the routes are converged in every layer. So in current Plane Model, when PE device extends to the edge layer, it has to maintain more VPN routes, which makes it difficult to extend the PE device to edge layer.Concern this problem, based on our rich experience on MPLS technology, Huawei propose a new solution for MPLS deployment which of the draft have already submit to the international organizationIETF.In this solution, we defines a model of Hierarchy of Provider Edge Device in BGP/MPLS VPN, where Hierarchy of Provider Edge Device can be composed of several PE and each PE plays the different part and partake the function of the normal PE(RFC 2547 PE). We call this model as Hierarchy Model in which the demand of performance in Routing and Switching is strict to the PE device in higher layer, loose to the PE device in edge layer. One HoPE can be composed of one SPE and several UPEs connected with the SPE, or be composed of one high-level SPE and HoPEs connected and build up a new HoPE. This build is called nesting of HoPE.This solution have been used by a lot of big account and accepted with high praise.Poster 5: CMCC National IP Bear Backbone in ChinaThis poster is the IP bearing network for CMCC. Huawei use 55 sets NE80/40 and soft-switch equipments to help CMCC to build up the National IP backbone Network. This IP backbone network is the most advance IP Telecom Network and the biggest capacity NGN IP Bear Network in the world.There are two planes in this network. The Plane A is responsible for NGN service, and the Plane B is responsible for VPN service and NGN NM service. They can work together and backup each other. When one plane failed, the service can switch over to the other plane less than 25ms, which does not impact the voice connection.This network has borne all the long-distance trunks of CMCC. Because the next generation network have to bear all the services, including voice, data, video, etc, so IP will be the core of the next generation network. And IP Bear Backbone is the base of all the next generation telecom network, such as NGN and 3GPoster 6: IZB Financial Backbone Network in Germany IZB is a financial operator in Germany. As we know the most impartment requirement in financial network is reliability, security and stability. After strictly testing, IZB select NE40 to build their backbone network because of its carries-class features and abundant services can satisfy all the requirements. This network helps IZB to provide the services, such as MPLS VPN, VoIP, to their customers.III. Introduction of Quidway Full Series ProductsThe 5th Generation Routers feature the performance of an ASIC and the flexible service support of a CPU. Designed with carrier-class ideas and featuring high reliability and perfect line speed forwarding performance, NetEngine series routers play important roles in national backbone and metropolitan backbone networks.NetEngine 5000E Terabit Core RouterThis is the highest router of Huawei. Exploiting the thinking derived from the 5th Generation router, NE5000E take use of two kinds of forwarding engine, one based on ASIC and the other based on NP, to leverage the requirement from both powerful performance and flexible service.A single chassis supports the line-speed switching of up to 64 10G-interfaces or 16 40G-interfaces. The switching capacity can reach 1.28Tbps, and the forwarding performance of the system can be 1600Mpps with single chassis.NE5000E supports maximal 64 chassis stack to scale the system switching capacity up to 80Tbps without service interruption and the forwarding performance can reach 100Gpps.Huawei is the one of few suppliers who can provide Terabit router in the world.NetEngine 80 Core RouterHighlightsi) NP-based IP core router, Carrier-class high Availabilityii) Forwarding capability:400M pps; Switch fabric: 512G bpsiii) Perfect Diffserv QoS Functionality and Feature-rich services provisioniv) Flexible upgrading for service: NSR, IPV6 and etc.v) Pass the compatible standard test with main-stream equipsNetEngine 40 Series Universal Switching RouterHighlightsi) NP-based IP universal router, Carrier-class high Availability, deliver 48M pps throughoutii) Perfect integration of Router and Ethernet Switchiii) Supports MPLS L2/L3 VPN and QoS functionalityiv) Abundant interfaces: GE, FE, POS155M/622M/2.5G, cPOS155M, RPR2.5G, ATM155M/622M, E1, E3v) Flexible upgrading for service: NSR, IPV6 and etc1) General informationNE40 series USR are a series of high-end routers.
