摘要： A universal network interface controller (UNIC) is provided for interfacing a host computer to a switch fabric, a packet network, or both. The UNIC includes ingress transmit logic designed to transmit switch fabric data in memory associated with the host computer to a switch fabric. The UNIC further includes egress receive logic designed to receive switch fabric data from the switch fabric to store the received switch fabric data in the host memory associated with the host computer. As an option, the ingress transmit logic may be further designed to transmit packet network data in memory associated with the host computer to a packet network, such as Ethernet, and the egress receive logic may be further designed to receive the packet network data from the packet network and to store the received switch fabric data and the received packet network data in the host memory associated with the host computer.

摘要： Certain aspects of a method and system for an adaptive queue and buffer control based on monitoring and active congestion avoidance in a packet network switch are provided. When memory from a memory source is not available for allocation to one or more adaptive queues in a network device, such as a network switch, the TCP window size associated with the one ore more adaptive queues may be reduced. The window size may be reduced to a target size by utilizing one or more reduction steps, wherein the reduction steps may be programmable. When portions of the memory source become available for allocation to the adaptive queues, the window size may be increased. The window size may be increased to a target size by utilizing one or more increase steps, wherein the increase steps may be programmable.

摘要： A system for encoding data in a multilane communication channel may include at least one processor operable to generate, from existing control characters in a character set, expanded control characters utilized for controlling the data in each lane of the multilane communication channel. Each lane of the multilane communication channel may transport the data in a similar direction. The at least one processor is also operable to control at least one of the lanes of the multilane communication channel using at least one of the generated control characters. If a first control character of the existing control characters is a start-of-packet control character, the at least one processor is then operable to select a second control character from any other of the generated expanded control characters, and to indicate a start of a packet using the selected second control character for at least one of the lanes.

摘要： Aspects of the invention utilize a secondary communication channel to conduct flow control at the word level. As a result, the overhead associated with flow control can be reduced, as well as the risk of buffer overflow. In one embodiment, embedded flow control information is encoded as reversed running disparity codes in each transmission lane. Additional control symbols may be coded by grouping a series of specially coded data words or inspecting a selected data word at regular intervals.

摘要： Aspects of the invention may include a method for encoding data in a multilane communication channel. The method may include generating from existing control characters in a character set, an expanded control character which may be utilized for controlling data in each lane of the multilane communication channel. The expanded control character may utilize spare link bandwidth. At least one of the lanes may be controlled using at least one of the generated existing control characters. If a first control character is an alignment character, a second control character may be selected from any other existing control characters. The first control character may be combined with the second control character to generate a third control character. Each of the combinations of the first and second control characters may represent an expanded control character. The existing control characters may be a configuration character, an idle character or an encapsulation character.

Aspects of one method may include pre-allocating packet buffers from a pool of packet buffers in a network switching device based on anticipation of a type of application data being handled by a particular port of the network switching device according to packet classification and tracking. The buffers may be dynamically allocated and deallocated from the pool of packet buffers for a particular port of the network switching device based on changes to the application data.
