Trends and Challenges
ITU-T Y.2011 defines the NGN network architecture, the network functions are two levels, service layer and transport layer, corresponding to the service layer and provide a platform for all kinds of service processing capabilities, network transport layer corresponds to the function of service transport functions, this standard framework laid the basis for bearer network.
With the process of all-IP evolution trends, operators must meet the requirements of next-generation network to provide service rapidly, support multi-service, easy to add new services, high scalability and low cost demands. Traditional network architecture using "chimney-type" model of network construction, based on "different services, different transmission" concept to achieve, has been unable to meet the development needs of a new era, in this condition, a "different services, uniform transmission "concept of a new horizontal hierarchy of the bearer network was born.
-
Bearer network definition: Refers to the network that handle the transmission of all types of services, to provide information transmission from the end to service platform as the bearer network, With the horizontal hierarchy, can provide all services for the general public structure and functional implementation modules;
-
Bearer network functions: In the middle of the process of handling a variety of services, the integration data layer user access authentication control, statistical multiplexing switching, packet routing and optical transmission layer multiplexing, routing, with high survivability, intelligent control plane, unified network management and monitoring plane
-
Significance of bearer network concept: The bearer network concept is a natural evolution of network development, represents technology integration, equipment integration, management integration, control integration and the development trend of network convergence, FMC;
-
Advantages of bearer network concept: Satisfy the requirements of next-generation network to provide service rapidly, support multi-service, easy to add new services, high scalability and low cost demands.
-
ZTE Bearer Network Strength: ZTE Bearer Network Solution adopts Uni-Bearer as the unifying concept, covering all parts of the bearer network, including the Uni-Backhaul, Uni-Metro and Uni-Backbone solutions
Customer Benefits
-
Unified network planning: Bearer network covers the optical layer and data layer, making the network planning can be highly integrated, fully support a unified platform for bearing a variety of services, easy to future evolution
-
Unified control plane: Bearer network made the concept of a unified control plane, making the network more intelligent for the future, fully oriented towards quickly provide services.
-
Unified Network Management: Bearer network covering the last mile, access aggregation and core backbone network applications locations, support a variety of technologies, the optical layer and electrical layer integration, and provides unified management for efficient customer network operating guarantee.
-
Reduce TCO: Unified bearer network-based network planning, unified control plane, and the concept of a unified network management, to meet the operators to rapidly service provisioning, support multi-service, easy to add new services, high scalability and low cost demands full account of the lower TCO, ease to ensure the customer network sustainable development.
