Example for Connecting to the CDN Server to the IPTV Network Through Two Switches That Form a Dual-Node Cluster on the Ring Network

Example for Connecting to the CDN Server to the IPTV Network Through Two Switches That Form a Dual-Node Cluster on the Ring Network

Solution Overview

With the rapid development of IPTV services, the IPTV platform needs to provide services to a growing number of users, who in turn raise increasingly high requirements on the reliability of the IPTV live broadcast service. IPTV is a type of video service, which means that end users have extremely high requirements on service continuity. Therefore, service continuity must be ensured during routine maintenance as well as in key event assurance and major version upgrade assurance.

Figure 3-118 shows the networking diagram of the broadcast and television network in a region. To ensure the quality of live TV, the live streams sent by the broadcast and television multicast source server must be first forwarded to the MRF transcoding server for transcoding and then forwarded by the transcoding server to receivers. The transcoding server is connected to the IPTV network through two switches that form a dual-node cluster on the ring network, thereby improving network reliability.

  • Normal forwarding path for multicast streams sent by the multicast source server: Core -> PE1 -> LSW1 -> CDN -> Transcoding server
  • Normal forwarding path for multicast streams transcoded by the transcoding server: Transcoding server -> CDN -> LSW1 -> PE1 -> AGG -> ACC1 and ACC2
  • Normal forwarding path for unicast streams sent from the recording server to a receiver: Recording server -> CDN -> LSW1 -> PE1 -> AGG -> ACC1 or ACC2
Figure 3-118 Video traffic forwarding path in the scenario when the CDN server is connected to two switches that form a dual-node cluster on a ring network

Configuration Notes

In this example, Core, PE1, and PE2 are modular switches, and the other devices are fixed switches. All S series switch models can be used in this example.

Networking Requirements

Figure 3-119 shows the IPTV network diagram in a region. A receiver can watch live TV programs and catch-up TV programs. The network requirements are as follows:

  • Multicast live streams sent by the multicast source server are first forwarded to the CDN server for transcoding and recording and then forwarded to receivers.
  • Receivers can also order catch-up TV programs in unicast mode.
  • Layer 3 multicast, L2/L3 mixed multicast, and IGMP snooping are deployed to forward multicast traffic.
  • OSPF is used to implement traffic forwarding at Layer 3. LSW1 and LSW2 establish neighbor relationships with PE1 and PE2 respectively in area 1 of OSPF process 1. Core establishes neighbor relationships with PE1 and PE2 in area 0 of OSPF process 1.
  • MSTP is deployed between CDN, LSW1, and LSW2 to prevent loops; VRRP is deployed on LSW1 and LSW2 to improve network reliability.
  • To ensure access security, traffic policies are configured on LSW1 and LSW2 to restrict the access of multicast source servers.
