Document History

Solution Description

The Cisco Wireline Video/IPTV Solution, Release 1.1, supports both broadcast video and video on demand (VoD) for the wireline market. This enables operators that use digital subscriber lines (DSL) and fiber to the neighborhood (FTTN) to offer not only video but also voice over IP (VoIP) and data (Internet access)—collectively referred to as "triple play"— over their existing infrastructure, now intelligently optimized for video service.

Document Version	Date	Notes
1	06/06/2006	This document was first published.

Note The first release of this solution was referred to as the "Cisco Gigabit-Ethernet Optimized IPTV/Video over Broadband Solution." The solutions are the same.

Figure 1 presents a generic view of the Cisco Wireline Video/IPTV Solution transport architecture. The shaded area shows the scope of solution testing and documentation. The solution uses a Gigabit-Ethernet (GE) transport network consisting of the following:

•

A super headend (SHE), where live feeds for the broadcast video service are located

•

A video switching office (VSO), where aggregation routers (ARs) that aggregate local or remotely attached GE DSLAMs are located

The regional access network, or RAN, consists of distribution, aggregation, and access layers. There is one SHE per region or network, and one VHE per metropolitan area. A distribution edge router (DER) provides transport for video traffic between the IP/MPLS core network and the VHO. The BRAS can either be colocated in the VHO or not. The real-time encoder encodes and compresses analog signals. The VHO, in turn, is connected to the VSOs through one or more ARs. The customer premises equipment consists of residential gateways, or RGs. (RGs are also referred to as home access gateways, or HAGs.)

Open Caveats—Release 1.1

•

CSCef28346—Long IGMP join latencies for multicast with the Cisco Catalyst 6000 series and Sup 720 have been seen with Cisco IOS Release 12.2(18)SXE and later releases.

Workaround—Use static joins, as described in "Effect of Multicast on Channel-Change Performance," in Chapter 3, "Solution Transport Architecture," of the Cisco Wireline Video/IPTV Solution Design and Implementation Guide, Release 1.1.

•

CSCsc16554—When the IGMP limit (state limit) feature is used with Source Specific Multicast (SSM) and source mapping, the feature does not work under all conditions.

When SSM is used and the client supports only IGMP version 2, source mapping is required. IGMPv2 messages cause the active group counter to increment properly. However, when the receiver sends an IGMPv2 leave message to the router, the active group counter (set by the ip igmp limit command) does not decrement. Consequently, all subsequent IGMP joins are denied.

•

CSCse09084—IP unnumbered is a requirement in DSLAM aggregation networks where numbers of VLANs are aggregated into one IP subnet. An option to add Dynamic Host Control Protocol (DHCP) host routes as connected routes is available in Cisco IOS. However, when "connected" mode is used, the clear ip route command causes DHCP host routes to be deleted permanently.

Workaround—Execute shut, then no shut, on the Layer 3 switched virtual interface (SVI).
