Next-generation multiplay networks are voice, data, and video networks that support personalized media and interactive IP television (IPTV) services along with communications services such as voice over IP (VoIP) and Internet data transmission. These services place extreme demands on network scalability, quality of service, security, and bandwidth resources. JUNOS software provides support for configuring various broadband video architectures in a multiplay network.
Although the overview in this chapter discusses more than one video network model, the example focuses on one specific video network architecture that incorporates a video services router running JUNOS software Release 8.3 or later. To understand this chapter, you should be familiar with Broadband Remote Access Server (B-RAS) operation on Juniper Networks routers, as well as standard Internet Group Management Protocol (IGMP) configurations.
For more information about B-RAS configuration, see the JUNOSe Broadband Access Configuration Guide. For more information about IGMP configuration, see the JUNOS Multicast Protocols Configuration Guide or JUNOSe Multicast Routing Configuration Guide. You can obtain these manuals at:
