摘要： Frame contained destination information may be used by a switch to identify an appropriate output port for a given frame without performing a table access operation. This reduces the processing requirements of the switch to enable the switch to handle frames more efficiently. The frame contained destination information may be contained in the frame's local destination MAC addresses (DA) such that a portion of the DA directly indicates, for each switch that handles the frame, an output port for that switch. Different portions of the DA may be used by different switches, depending on where they are in the network hierarchy. Large switches may also use sub-fields within their allocated portion in the DA to identify internal switching components. A location resolution server may be provided to store and distribute IP and MAC addresses and respond to local ARP requests on the local domain.

摘要： Device-wide performance guarantees may be implemented in a network element using a pull forwarding scheme by using separate proceses on the network element communicating via handshake signals to enable coordination between the aspects of the network element. One class of processes execute at the ingress queues, a second class of process execut at junction points, and a final class of processes execute at the egress ports. The combination of these separate processes leads to the correct scheduling of frames in a device-wide manner as if there were a centralized scheduler with complete information about all queued frames. As a result, the performance guarantees of the intended scheduling algorithm are preserved and are provided in a device-wide manner. The scheduling algorithms that are supported include round-robin, deficit round robin, negative deficit round robin, weighted round robin, and strict priority.

摘要： An edge device is used to support a backbone provider bridging network to facilitate interconnection of a plurality of networks. The edge device is coupled between the backbone and a first one of the networks, and is operable to encapsulate data units received from the first network with a header, and to forward the encapsulated data unit to the backbone. The header is indicative of a tunnel that is used to support traffic from the first network to a second network over the backbone. The edge device also de-encapsulates data units received from the backbone that are destined for the first network.

摘要： FIFOs may be implemented in shared memory using linked lists and interleaved linked lists such that any individual FIFO can dynamically use any free memory location. The system may be implemented in hardware efficiently and does not pre-allocate memory to any FIFO, so that the whole shared memory may be used by any one of the FIFOs. The maximum physical size of a FIFO is then limited only by the size of the physical memory and not by the number of FIFOs sharing the same physical memory or by any mechanism for pre-allocating physical memory to the FIFOs. The linked lists contain data words, each data word containing a data field and a reference to a subsequent free memory location. A subsequent data word may be enqueued to the FIFO at the last referenced free memory location. A dequeue operation returns free memory locations to the free memory pool. Multiple linked lists may be interleaved to accelerate reading of data words from the FIFO.
