摘要： Various techniques can be used to handle frames within multi-stage switching fabric. For example, in one method, a frame and an associated frame header are received at a switching fabric stage. The associated frame header includes a first field and a second field. The method selects one or more fabric points of exit within the switching fabric stage, based on the second field. The first field is used to select one or more other fabric points of exit within another switching fabric stage, and thus two different fields within the associated frame header specify fabric points of exit. The method then sends the frame to the selected fabric points of exit within the switching fabric stage.

摘要： A self-adjusting load balancing among multiple fabric ports. A plurality of first values is received in response to receiving a first frame, wherein each of the first values is related to a quantity of data stored in a respective one of a plurality of buffers of fabric ports. First identifiers are also received, each of which corresponds to a respective one of a first subset of the plurality of buffers. A subset of the first identifiers is selected based on one or more of the first values. Thereafter one of the first identifiers contained in the selected subset is selected. Ultimately the first frame is transmitted to the buffer that corresponds to the selected one of the first identifiers.

摘要： A method for receiving packet data at a communication channel and transmitting the packet data over serial links of the communication channel. The packet data is sliced into n-bit data portions which are concatenated with a header prior to transmitting an n-bit portion across one of the serial links of the communication channel. The header includes a CRC to provide improved error detection.

摘要： An integrated circuit monitors the most active traffic flow rates on a communications network by using a leaky bucket model having a variable fill rate. As a switch receives packets, the packet identifications are sampled. A sampled packet identification is compared to record identifications in a table of identifications. If the sampled and record identifications match, an activity value for the packet identification is increased by an amount inversely proportional to an activity value associated with the record identification. If the sampled and record identifications do not match, the activity value is decreased. Record identifications are removed from the table when the activity value decreases to a specified level. New sampled identifications are added to the table if empty records exist.

摘要： A method, system, and apparatus to transmit replicated multicast packets over a plurality of physical network links that are combined into one logical channel or link so that the replicated multicast packets are distributed over more than one network link is disclosed. It is further disclosed that distribution over the network links is accomplished, in part, through analyzing the multicast packet for information other than ethernet addresses. Such information can include a tag header including destination interface information.
