MPLS VPN Mixed With MSTP Private Network Design And Implementation

With the further development of a large company, the original communication mode has already can’t meet the needs of the rapid development, and companies in the network quality, speed and security put forward higher requirements. MPLS VPN technology with high speed, flexible access and wide bandwidth multiplexing technology etc, is mainly used to have higher demand on network bandwidth video monitoring lines or lower to the network security requirements of small and medium-sized enterprise network requirements. MSTP technology with its traditional digital line protection of physical isolation, loop high security features, such as government, finance, military garrison the use of more users. Two network together to form a new kind of special line network, can provide large enterprises across the province, city or even nationwide now the high rate of bandwidth and high security network to provide solutions.This article from the principle of MPLS VPN and MSTP network technology, MPLS VPN research including the principle of MPLS VPN, MPLS label packet forwarding, MPLS VPN architectures, MPLS VPN routing, etc. MSTP technology introduction includes summary of MSTP, MSTP technology development, MSTP technology advantages and key technology of MSTP, etc. In the full study of two kinds of network analysis, on the basis of the two kinds of network, proposed the feasibility conclusion mixed together to form a private network for two kinds of networks after mixed private network construction has carried on the detailed argumentation, structured for two kinds of mixed to form a network message transfer and forward process after done. In the study found that both the network can provide good network support for the etheric business, and found that two types of network in some ways the supported business have similarities, theoretically verified the feasibility of the two together to form a network.After completion of the theoretical research, combining with the theory of knowledge, in the China PICC shandong province branch cross domain network forming process, using the hybrid network. In the process of the network sets up, the research on the network needs of customers first, on the basis of summarizing the research results, according to the mixed network model for the client network planning believe the network topology, in accordance with the requirements of the network topology and network design to achieve the required, selection of equipment. Determine the device type, each of the network devices in the network formed by planning data and configuration of equipment in accordance with the data plan. According to the network design, for the network can realize the function of the tested, before can completely reach the design requirements.In the process of the entire network to form, both can verify MPLS VPN and MSTP network can be combined with each other in private network construction. In MPLS VPN network as the cross-domain throughout the network transmission trunk, MSTP as a mixture of private network access for network to form a part this way, can reduce the original single use MSTP to form a network charges, and can also provide access to high speed, large bandwidth, can also reduce the single use of MPLS VPN network security risk.
