Cisco Mpls Network Solution Specifically Detail - Cisco, Mpls Private Network, Network-it Industry

Expertise in the power network, with the Network The rapid development of processor technology

, 2.5G or 10G wire-speed routing ports have been no problem to find, MPLS MPLS applications have gradually turned to other traffic engineering and MPLSVPN. Cisco MPLSVPN power special network solutions, MPLS traffic engineering technology as a major management of network traffic, reduce congestion, to some extent guaranteed QoS IP network, an important tool.

MPLSVPN special network architecture as "meridians", played the role of the connection. Following is a typical tree our special network solutions (Inner Mongolia Electric Power special network solutions), for example, from multiple perspectives.

In this solution, the biggest advantage of using MPLS backbone network traffic can be improved. Traffic Engineering is such a process: the availability of resources, current and expected flow of the management point of view, for data routing. The data required for service level and quality of the elements of this process is. Traffic Engineering can be controlled, the administrator monitor the network status, and routing of traffic, when the fault occurs, to provide additional resources to compensate.

Traffic Engineering to help network providers the maximum possible use of available resources; spread the burden of data link layer link; also allow some links to be retained to ensure that traffic levels and the number of special services to users. In the past, in order to meet these demands, network providers have to increase their physical network devices. The MPLS provides a good way to avoid the use of constraint-based routing to allocate network resources and the problems brought about.

The other hand, the power of information in the Cisco solution, MPLS labeled with pre-configured with the third layer in the core equipment of information exchange correspond to the table so that each Switch Automatically to each packet corresponding to the correct IP business. Switching table is precomputed, so no need to reprocess each packet relay section. This program can not only distinguish the type of business, such as the "best effort" the daily electricity business (information query, communicator, etc.) and the key tasks (such as power marketing, professional scheduling, etc.) to distinguish the application.

The same time the power of Cisco MPLS solution highly scalable. Use different strategies for MPLS packet distribution mechanisms for marking, it will forward the packet IP header and the content separate. Tag have meaning only in the local, and their large-scale networks can be reused many times; therefore, mark used almost impossible. This feature for achieving QoS, VPN and traffic Siu-level management and other advanced IP services is very important.

In the settlement enterprise interconnection, providing a variety of new business, MPLSVPN power enterprises will become more favorable, as in the IP network operators to provide an important means of value-added services. Technology can be used MPLSVPN the existing IP network broken down into separate logical network, this logical separation of network application may be changing: can be used in a separate upstream and downstream enterprises to solve the power interconnection at all levels, and different work sectors separate interconnection can also be used to provide new services when --- as for the IP telephony has opened a dedicated VPN, in order to solve shortage of IP network address, QoS assurance, and new business issues.
