Architecture of a 100-Gbps network processor for next generation video networks

As the escalating demand for bandwidth continues, 100-Gigabit networks mark the new frontier to be ventured by networking equipment vendors. Network processors (NPUs), fast emerging as key components in 10-Gigabit platforms, will also empower the 100-Gigabit platforms. However, packet processing at these line rates presents significant challenges to network processor designs. The most important driving factor for the exploding bandwidth demand is video traffic. Supporting video traffic imposes even further challenges due to its real time and low jitter requirements. These challenges are amplified when attempting to construct a network with IPTV-grade capabilities. In order to address these challenges it is crucial for the routers, and the network processors in their cores, to be video aware and demonstrate special treatment for this demanding traffic.
