Multi-Service IP MAN Solution

Multi-Service IP MAN Solution

This section describes the multi-service IP MAN solution.

Figure 5-3 shows how the NE40E is applied on a multi-service IP MAN.

Figure 5-3 Application of the NE40E on a multi-service IP MAN

An IP MAN consists of three layers: core layer, service control layer, and access layer.

The NE40E is usually deployed as the core or aggregation node on IP MANs. The NE40E is mainly deployed as the core, aggregation node, or service control node on IP MANs.

The core layer is responsible for high-performance and large-capacity data forwarding. It requires a simple network structure as well as secure and reliable transmission of multiple services. The IP/MPLS technology is deployed at the core layer, allowing the physical network to implement multiple logical service bearer planes through the MPLS VPN technology. To ensure network reliability, the core layer uses many reliability techniques, such as device-level reliability, network-level reliability, and inter-AS reliability. The core-layer devices have large capacities, high-density interfaces, and high forwarding performance, meeting the requirements of the core layer.

The NE40E provides the following functions to meet the IP MAN core layer requirements:

  • The NE40E has a powerful switching capacity. The interface capacity of a single system reaches 640 Gbit/s. The NE40E provides 100GE interfaces at line speed and high-density GE interfaces.
  • The NE40E provides powerful routing capabilities and various routing protocols. The NE40E supports IP/MPLS and provides multiple VPN solutions, such as BGP/MPLS L3VPN and MPLS L2VPN. In this manner, multiple services are carried over the logical bearer plane of the core network, and service isolation and security can be implemented.
  • TheNE40E supports Seamless MPLS. Seamless MPLS is a bearer technique that extends MPLS techniques to access networks. Seamless MPLS establishes an E2E LSP across the access, aggregation, and core layers. All services can be encapsulated using MPLS at the access layer and transmitted along the E2E LSP across the three layers. Seamless MPLS simplifies network provisioning, operation, and maintenance.
  • The NE40E supports inter-AS VPN Option A/B/C. This guarantees inter-AS service reliability.
  • The NE40E provides carrier-class reliability, such as redundancy of key modules and in-service patching. In addition, the NE40E provides various FRR techniques, such as IP FRR, LDP FRR, and TE FRR.

The service control layer supports user access management, security control, and service control and provides a platform for the operation of telecommunications services to implement user-level management and control.

The NE40E supports IPoE/PPPoE/L2TP user access and integrates functions of the conventional BRAS such as user authentication, call control, policy control, QoS guarantee, and security guarantee over various services. In this way, the requirements of the service control layer are met and the weakness of conventional routers and firewalls that cannot meet carrier-class operation requirements is overcome, greatly reducing the operation cost.
