Multi-Service Transport Platform (MSTP) technology, based on the SDH platform, can simultaneously realize the access, processing and transmission of services such as TDM, ATM, and Ethernet. It is a multi-service transport platform that provides unified network management.
With the development of the times, a variety of network transmission forms appear in network applications, such as file, video, image, and data transmission, resulting in a certain area of network capacity that cannot meet a large number of service transmission requirements. To deal with this problem, MSTP not only provides nodes for various forms of network services and realize mutual transmission between platforms but also provides unified management to promote the normal operation of business.

○   The transmission network provides end-to-end bandwidth rate guarantee;

○   Using Ethernet access mode and bandwidth can be flexibly adjusted.(provide 2M to 10G access bandwidth options);

○   Multi-service bearer function: transparent transmission of upper-layer services, capable of bearing multiple services such as voice and video;

○   Flexible networking: support star network, ring network, point-to-point connection, multi-point aggregation, etc.;

○   Each transmission channel is physically isolated, which effectively prevents outside intrusion and ensures strong communication confidentiality;

        Based on the key technologies of the IP/MPLS protocol, IP RAN is an end-to-end service bearer network composed of the CN2 backbone layer. IP RAN is mainly geared towards mobile service bearers and provides service bearer networks with Layer 2 and Layer 3 channels.

○   End-to-end IP reduces network complexity and simplifies network configuration;

○   Using Ethernet access mode and bandwidth can be flexibly adjusted.(provide 2M to 10G access bandwidth options);

○   Adopt dynamic addressing method to realize automatic route optimization in the bearer network;

○   The dynamic three-layer networking mode can better meet the requirements of multi-service integration;

○   Network-wide OAM management and hierarchical end-to-end QoS to realize intelligent management of network policies;

        PTN is a packet transmission network technology designed for the burstiness of packet traffic and the requirements of statistical multiplexing transmission. It takes packet service as the core and is applied to multi-service environment. PTN can support two-way point-to-point connection channel and is suitable for various coarse and fine-grained services. It has the advantages of multi-service, high reliability, manageability and clock synchronization.

○   Support point-to-point, point-to-multipoint, and multipoint-to-multipoint services;

○   Using Ethernet access mode and bandwidth can be flexibly adjusted.(provide 2M to 10G access bandwidth options);

○   It supports ring network protection, link protection, linear protection and link aggregation;

○   It adopts an end-to-end QOS design, which can provide refined load-bearing and perfect grading quality assurance;

○   It inherits the end-to-end management capabilities of SDH, which is convenient to manage and easy to maintain;
