Report: Network line cards may limit IPTV delivery

Design and performance limitations of network line cards, the components that connect telecom switches and routers to end-user access lines, may limit efforts by telecom network operators to deliver advanced services such as IPTV to homes and businesses, according to the latest report published by the subscription research service Light Reading Insider.

The 26-page report, “IP Network Line Cards: Next-Gen Challenges,” analyzes the relationship between emerging network requirements and IP network line card design.

Delivery of IPTV and other multimedia services is pushing performance requirements beyond what the current generation of IP network line cards can deliver, the report said.

Silicon design cycles are not yet aligned with market demands, resulting in a time-to-market lag that will continue to pose problems for makers of line cards and the telecom equipment manufacturers they supply.
