IPTV Bearer Network Solution

IPTV Bearer Network Solution

This section describes the IPTV bearer network solution.

Figure 5-2 shows how the NE40E is applied on an IPTV bearer network.

Figure 5-2 Application of the NE40E on an IPTV bearer network

This solution has the following characteristics:

  • The IPTV bearer network and the original MAN access network share the same platform. The IPTV bearer network is therefore integrated with the entire network architecture of carriers.
  • The NE40E at the core layer is used to build an MPLS VPN and construct the logical plane for various services. In addition, the NE40E forwards data at a high speed and provides high-performance QoS.
  • The BRAS at the service control layer is deployed as follows:

    • In the early phase of IPTV service deployment, normal services and IPTV services access the same BRAS for distribution. Not much modification must be done on the entire network, and new services can be launched quickly.
    • As large-scale services develop, dedicated IPTV BRASs are required. Broadband access services access the original BRAS; IPTV services access the dedicated IPTV BRAS. In this manner, IPTV services are isolated from other services, and the requirements of high-volume IPTV traffic are satisfied. In addition, the powerful control capabilities of the BRAS ensure secure access of IPTV services. IPTV services and other services are then distributed on Layer 2 aggregation devices.
