A Research on MPLS Switch Architecture Based on ATM;

Since multicast traffic exhibits an increasing proportion of traffic on the Internet,switch architecture and scheduling policy must afford good support for multicast traffic.

Scheduling algorithms make a great impact on the performance and implementation complexity of switch architecture.

OPNET-based traffic source model for switching fabric in high-speed routers;

Research and discussion on switching fabric of broadband switch;

Latency of multi-ary hypercube switching fabric in the terabit router;

iSLIP algorithm is easily implemented in hardware and accomplishes convergence by no more than log_2N times, but it has not high efficiency in burst communication; it is suitable for small and middle scale high speed switch fabrics.

Analysis of scalability of the switch fabric;

Double input sharing is introduced into the switch fabric of grouping 15×15 crossbar with fan out of five.

VHDL level simulation is very important and indispensable in designing switch fabric.

The rapid developing of data services and the increasing of fiber capability request the switching structure of the optical network to have more intelligence, bigger switching capability, lower rate of backup and less cost, which the traditional optical network can t provide.
