Poster 2: IP Telecom Network (IPTN)
Introduction of Datacomm technologies innovated by Huawei

As a member of major international communication standard organizations
and forums such as ITU-T, IETF, MPLS, RPR and ATM, Huawei has been actively
participated in 39 international standardization organizations and submitted a
mass of proposals focusing on the development of IP Network, such as
HoPE(Hierarchy of Provider Edge Device in BGP/MPLS VPN)
and
Building
Carrier-Class IP Networks
.
As we all know, the telecommunications network of the next generation will
inevitably be a multi-service intelligent network with IP technology as its core, and
this will be an inevitable result of the development of both technologies and
industries.
Viewed from the point of technologies, the traditional telecommunications
network can no longer meet the requirements of further development, and the
current Internet is defective in terms of operation management and service
providing capability, whereas IP telecom network based on IP technology +
telecom-level operation requirements will be the next development direction.
Viewed from the point of industry development, all the factors of defection of
the original technologies, changes of service environment, the downturn of voice
services, the upturn of data and integrated services, and that new carriers are
liable to use new technologies, have promoted the evolution of telecom network
of the next generation to IP telecom network.
Based on such analysis, Huawei put forward the theory named “IPTN”- IP
中英文日报导航站
中英文日报导航站
Telecom Network which be received by ITU-T as the drafts of Next Generation
Network.
Huawei’s IP telecom network solutions apply the call management
experiences of telecom networks to IP networks and implement the dynamic QoS
policy management of call-based real time network bandwidth and service priority
adjustment, which greatly improves the service quality of the IP base network.
As shown in the above diagram, the basic network layer will be divided into
two different logical networks, i.e., the IP telecom network and Internet, by means
of resource separation via the MPLS technology. 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 Router
As 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 4
th
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 5
th
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. Huawei’s high-end routers all base on NP technology
and Huawei has been the spokesman of the 5
th
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
中英文日报导航站
中英文日报导航站
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 organization——IETF.
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 China
This 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
中英文日报导航站
中英文日报导航站
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 3G…
Poster 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.
