A configurable switching fabric port is disclosed having, in a particular configuration. A first interface that employs port interface resources and leaves at least one interface resource dormant and a second interface utilizing the dormant resource. One particular fault non-tolerant architecture, the RapidIO System, is specifically addressed. One implementation of this system incorporates transmission and reception ports configurable as 16 and 8 bit interfaces. In the 8-bit configuration, an 8-bit interface incorporates the least significant 8-bits of signal resources. Further, in the reduced, or 8-bit configuration, the most significant port interface resources of the 16 bit port are surplus.

Method and system for providing fault tolerance in a network

A buffer management system for cooperating with a packet based switching system is proposed. The purpose of this system is to reduce traffic congestion, ameliorate its effects, provide fairness to each data source, and to increase functionality while respecting advantageous system characteristics. Fabric output buffers include an arbitration function, a quality of service function, and are associated with individual routing tables. The system uses shallow logic that allows for single clock cycle operation even at high clock speeds. In order to provide for system control of bandwidth, sources with bandwidth practices counter to system interests are addressed. Where there is a conflict of sources over a resource, the buffer management system arbitrates traffic to resolve conflicts in a timely manner while fairly allocating traffic share using a weighted round robin arbitration scheme.
