Alcatel-Lucent TPSDA 2.0 Steals Microsoft's Thunder

Alcatel-Lucent has introduced IPTV application awareness into its Triple Play Services Delivery Architecture (TPSDA) 2.0. It will add flash storage to its edge routers, its switches, and its access nodes that will support fast channel change, packet retransmission, and targeted ad insertion.
  • For fast channel change the last few minutes of every multicast channel will be stored in the network and the new channel will be started immediately, eliminating the latency that typically occurs today. Alcatel-Lucent said that HD channel change time will be reduced from several seconds to well under a second.
  • For packet retransmission the network will store enough packets to immediately service the packet retransmission request.
  • For ad insertion targeted ads will be stored and inserted in the network.

If the service provider uses Alcatel-Lucent access nodes, these functions can be provided in the access network. These functions can also be provided in the Alcatel-Lucent switches or edge routers for service providers using Alcatel-Lucent's TPSDA 2.0 architecture.

Alcatel-Lucent has also discussed plans to increase the amount of storage in these network elements in order to support rewind TV and video on demand delivery.

TPSDA 2.0 can support these functions for service providers using access nodes from other manufacturers by implementing them in the switches and edge routers.

Microsoft has not announced any support for these network capabilities.

This is an interesting announcement. It enables middleware companies other than Microsoft to support fast channel change. This includes both the Alcatel-Lucent MiView and OMP middleware as well as other middleware from companies such as Thomson and Orca. This approach to fast channel change will eliminate one of Microsoft's most competitive features.

This approach will give service providers new flexibility in managing the bandwidth demands from an IPTV service, especially as more and more on demand and personalized services are provided. I think the flexibility that it gives in placing storage in the network will improve the ability of service providers to optimize their networks.

From the information at BBWF I can add some information.

TPSDA has over 50 (55?) deployments worldwide for IPTV services. only a minority of which are Alcatel Lucent Middleware or Microsoft.

Alcatel Lucent also have a highly scalable "server" approach that can be mixed in or used with non TPSDA IPTV deployments.

Interesting stuff.

Finally, Alcatel+Lucent is back on track and focusing on their core business and strength. What a Thunder!
