Principles and key technologies of MSTP

With the growing demand for IP data, voice, image and other service transmission, the broadband technology of user access and the resident network has been rapidly popularized, and the large-scale construction of the transmission backbone network has also been promoted. Due to the drastic changes in the service transmission environment, the original metro area network with the main purpose of carrying voice can no longer meet the requirements of service transmission and aggregation in terms of capacity and interface capacity. As a result, MSTP (Multi-Service Delivery Platform) technology came into being.

MPLS is a multi-protocol label switching standard protocol proposed by Cisco in 1997 and formulated by IETF, which uses layer switching technology to organically combine Layer 3 technology (such as IP routing, etc.) with Layer 2 technology (such as ATM, Frame Relay, etc.), so that it can provide both point-to-point transmission and multi-point transmission on the same network. It can not only provide the best service of the original Ethernet, but also provide real-time switching services with high QoS requirements.

There is it in the library, you can take a look.

MSTP technology supports the dedicated line for key customers.

MSTPMSTP technology originates from SDH, after continuous development in recent years, has included PDH, SDH, POS, Ethernet, ATM, RPR, SHDSL, DDN and other technologies in one, it can not only realize the comprehensive transmission of metropolitan area network services through multi-service aggregation, but also realize service access and processing through its own adaptability to multiple types of services, which is very suitable for the development trend of the integration of various technologies of metropolitan area network, and has become a relatively complete metro network technology system.

From the perspective of the development status of the business and the application of MSTP technology on the Internet, in the MSTP transmission technology: POS technology can provide more reliable and efficient channel connection for IP interconnection; ATM ring network technology can realize ATM-based DSLAM sharing and aggregation; PDH and SDH access functions can efficiently handle a large number of TDM services. High-speed Ethernet interconnect technology enables reliable interconnection between a wide range of data devices. With the development of metro data services, data processing functions such as MSTP Ethernet aggregation and transmission technology and RPR dynamic packet ring network technology will be widely used in the near future.

We know that MSTP technology inherits the stable and reliable characteristics of SDH in terms of transmission function, and integrates the flexible and diverse service processing capabilities of the data network, which can be widely used in the access of large customer private lines, Ethernet access, DDN private lines and other services, and can play an increasingly important role in data metro services.

MSTP technology is capable of accepting special lines for large customers.

From the perspective of metro data service network requirements to provide customers with a full range of SLA services, MSTP has the ability to accept various high-level private line services and play a role in actual network applications. According to the SLA service principle of leased services, the carrier network should be able to provide services from the highest level to the lowest level to meet the needs of different types of customers for private lines. If some end users do not have a thorough understanding of the operating network and look at leased circuits with a distrust mechanism, then MSTP technology also has some characteristics that data networks do not have, such as security, transparency, and manageability, in solving the private line requirements of large customers.

For the real SLA-based VIP private line service, in addition to providing the data services that have been solved by the data network, MSTP also has high-level services with information transparency, bandwidth transparency, high security and manageability, which can more appropriately meet customer needs, thereby improving the comprehensive competitiveness of the network and avoiding the best war caused by IP network homogeneity. Therefore, from the perspective of the current situation of IP data network and the end user's perception of IP data network, organically combining MSTP technology with IP data network will become an ideal solution to realize the private line business of large customers in recent years.

Thanks if it helps!

1) At this stage, a large number of users still demand fixed bandwidth private lines, mainly 2Mbits, 10 100Mbits, 34Mbits, and 155Mbits. These leased line services can be broadly divided into fixed-bandwidth services and variable-bandwidth services. For fixed bandwidth services, MSTP devices integrate excellent bearer and scheduling capabilities from SDH, and for variable bandwidth services, they can directly provide end-to-end transparent transmission channels on MSTP devices to fully ensure the quality of service, and can make full use of MSTP's Layer 2 switching and statistical multiplexing functions to share bandwidth and save costs.

2) In the metro aggregation layer, the service aggregation from the edge node to the central node of the enterprise network is realized, which has the characteristics of many nodes, multiple port types, scattered user connections, and a large number of ports. Using MSTP networking, it can realize the aggregation or direct access of 10M, 100M, 1000M, and 2M/FR services of IP routing devices, support service aggregation and scheduling, comprehensive bearing, and good survivability. Depending on the network capacity requirements, you can select MSTP devices of different rate classes.

Combining the advantages of ATM and SDH, the service is integrated, the network layer is simplified, and the bandwidth utilization is improved.

Hello dear and happy to serve you. The answer to your question is as follows: MSTP stands for Multiple Spanning Tree Protocol.

It is a network protocol that is mainly used to implement multiple spanning trees in a switch network, thereby improving the reliability and performance of the network. The main implementation of MSTP includes the following aspects:1

Multiple spanning trees are supported, and each spanning tree can be configured independently to adapt to different network topologies and needs. 2.Spanning tree prioritization is supported, so that you can designate one spanning tree as the primary spanning tree and other spanning trees as backup spanning trees.

3.Supports port classification, which can divide switch ports into different types, such as root ports, design ports, and blocking ports, to adapt to different network topologies and requirements. 4.

When the network topology changes, MSTP can quickly recalculate the spanning tree to ensure the reliability and performance of the network. In general, the main implementation of MSTP is to implement multiple spanning trees in the switch network to improve the reliability and performance of the network bend cover.

It is based on the traditional SDH platform, which can simultaneously realize the access, processing and transmission of TDM, ATM, Ethernet and other services in the same branch, and provide a unified network management in the process. MSTP is formed by the technical improvement of SDH, in addition to all the functions that SDH has, it also has the following four functions. (1) It has the function of receiving people from TDM and ATM and Ethernet.

2) It has the transmission function of TDM and ATM and Ethernet, which can realize the point-to-point transparent transmission.
