The subject specification comprises techniques employing multi-stage multi-layer switches for packet switching using fully shared buffers with a scalable switch fabric. A switch component includes a set of input modules (IMs) of switches that receive packets and are associated with a set of central modules (CMs) of switches that are associated with a set of memories. The switch component includes a second set of CMs associated with the set of memories, the second set of CMs being associated with a set of output modules (OMs) that can provide packets as output. A switch management component controls switching of the packets between the IMs and first set of CMs to the memories during a first switching phase, and switching of the packets from the memories to the second set of CMs to the OMs for output during a second switching phase, based on a defined scheduling algorithm.

Lookup techniques are described, which can achieve improvements in energy efficiency, speed, and cost, of IP address lookup, for example, in devices and systems employing ternary content addressable memory (TCAM). The disclosed subject matter describes dividing a route table into several sub-tries with disjoint range boundaries. In addition, the disclosed subject matter describes storing sub-tries of a route table between a TCAM and a faster and less costly memory. The disclosed details enable various refinements and modifications according to system design and tradeoff considerations.

Efficient lookup methods for ternary content addressable memory and associated devices and systems

A WLAN communication system and algorithm that adaptively changes the data transmission rate of a communication channel based on changing channel conditions. The WLAN communication system or algorithm has two modes being a searching mode and a transmission mode. Furthermore, the WLAN communication system or algorithm incorporates an additive increase, multiplicative decrease (AIMD) function into the rate adaptation algorithm.
