摘要： Access control lists (ACLs) permit network administrators to manage network traffic flowing through a networking element to optimize network security, performance, quality of service (QoS), and the like. If a networking element has multiple ACLs directed towards different types of network optimization, each ACL may return a separate action set that identifies one or more actions the networking element should perform based on a received frame. In some cases, these action sets may conflict. To resolve the conflicts, a networking element may include resolution logic that selects one of the conflicting actions based on a predefined precedence value assigned to each action in an action set. By comparing the different precedence values, the resolution logic generates a new action set based on the actions with the highest precedence value.

摘要： A method, a system, and a computer program product is disclosed for identifying a quality of service (QoS) classification of a packet in a network by a network processor. The method comprising: providing a table wherein a priority value with a maximum of N values is used as an index into the table to retrieve a QoS classification having a maximum of M values with M less than N; receiving a data packet in a stream of data packets; extracting at least two priority indicator values from the packet; converting the at least two priority indicator values into a priority value; utilizing the priority value as an index into the table; extracting the entry in the table corresponding to the priority value as the QoS classification of the packet; and utilizing the QoS classification for subsequent processing of the data packet.

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. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, where the routing table is divided into slices of buckets, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions and properties of the slices.

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： 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.

摘要： Techniques are provided for cached routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry, based on a set of hash functions. Upon accessing the generated routing entry in the modified routing table responsive to a subsequent lookup request for the source address, the set of caches is modified to include the generated routing entry.

摘要： Systems and methods to forward data frames are provided. A particular method may include receiving a data frame at a distributed virtual bridge. The distributed virtual bridge includes a first bridge element coupled to a first server computer and a second bridge element coupled to the first bridge element and to a second server computer. The distributed virtual bridge further includes a controlling bridge coupled to the first bridge element and to the second bridge element. The controlling bridge includes a global forwarding table. The data frame is forwarded from the first bridge element to the second bridge element of the distributed virtual bridge using address data associated with the data frame. A logical network associated with the frame may additionally be used to forward the data frame.
