摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received by a switch module having bridge elements and a routing table divided into slices of buckets, each slice having a respective property and including one or more buckets. If a routing entry for the source address is found in a first slice of a first set of buckets of the routing table responsive to a lookup request for the source address, and the property of the first slice satisfies a replication condition, then the routing entry is replicated to a second set of buckets of the routing table.

摘要： Systems and methods to communicate data frames are provided. A particular apparatus may include a first adapter having a first queue configured to store a data frame associated with a first priority. The adapter is configured to generate a first priority pause frame. A distributed virtual bridge may be coupled to the first adapter. The distributed virtual bridge may include an integrated switch router and a first transport layer module configured to provide a frame-based interface to the integrated switch router. The transport layer module may include a first buffer associated with the first priority. A first bridge element of the distributed virtual bridge may be coupled to the first adapter queue and to the first transport layer module. The first bridge element is configured to receive the first priority pause frame from the adapter and to communicate an interrupt signal to the first transport layer module to interrupt delivery of the data frame to the first queue.

摘要： An assignment constraint matrix method and apparatus used in assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device. The assignment constraint matrix is implemented as a plurality of qualifier matrixes adapted to operate simultaneously in parallel. Each of the plurality of qualifier matrixes is adapted to determine sources in a subset of supported sources that are qualified to provide work to a set of sinks based on assignment constraints. The determination of qualified sources may be based sink availability information that may be provided for a set of sinks on a single chip or distributed on multiple chips.

摘要： Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer, at least one packet interface, and an analysis assist layer. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis assist layer analyzes the packet to determine a reason code to assign to the packet. The analysis and bifurcation layer then analyzes the packet based at least in part on the reason code.

摘要： Techniques are disclosed for hash-based routing table management in a distributed network switch having multiple switch modules. Upon determining that an attempt to insert a first routing entry into a first hash table of the routing table has failed, a second routing entry, which exists in the first hash table, is attempted to be moved to a second hash table of the routing table. If the move attempt is successful, then the first routing entry is added to the location previously occupied by the second routing entry. If the move attempt is unsuccessful, then a third routing entry, which exists in the first hash table, is attempted to be moved.

摘要： A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address.
