Abstract :
The protocol-independent (π) family of ASIC devices, which we present in this paper, allows to build cost-effective IP routers and ATM switches capable of providing sophisticated Quality-of-Service (QoS) guarantees in the form of throughput, delay and jitter to individual flows or to aggregation of flows. The new chipset, which represents the evolution of the widely used ATLANTA chipset, comprises five devices. The devices presented considerable design and verification challenges, due to the complexity and required speed of the desired QoS functionality. To solve these challenges, we devised a number of design techniques, as well as a novel ad-hoc verification approach
