摘要： Techniques to load balance traffic in a communication network include a network switch or device having an interface to receive a data unit or packet. The network device includes a hash value generator configured to generate a symmetric key from an initial key that is based on the packet, and configured to generate a hash value based on the symmetric key and the packet. The hash value may be optionally modified to load balance egress traffic of the network device. The network device selects an egress link or port, such as by determining an index into an egress table based on the (modified) hash value. The techniques described herein allow packets or data units of a particular flow to travel in both directions along a same path through the communication network.

摘要： Techniques to load balance traffic in a network device or switch include a network device or switch having a first interface to receive a data unit or packet, a second interface to transmit the packet, and a mapper to map between virtual ports and physical ports. The network device includes hash value generator configured to generate a hash value based on information included in the packet and based on at least one virtual port. The hash value may be optionally modified to load balance egress traffic of the network device. The network device selects a particular virtual port for egress of the packet, such as by determining an index into an egress table based on the (modified) hash value. The packet is transmitted from the network device using a physical port mapped to the particular virtual port.

摘要： In a method for processing data packets in accordance with a timing protocol, a data packet that includes i) a checksum and ii) a timestamp is received. The timestamp is modified to generate a modified timestamp and a checksum trailer value is determined to maintain correctness of the checksum in the data packet having the modified timestamp. Additionally, at least a portion of a field of the data packet is set to the checksum trailer value, where the field is defined by the timing protocol for use other than a checksum trailer.

摘要： Techniques to avoid polarization in a communication network include a network switch or device having a first interface to receive a data unit or packet, and a second interface via which the packet is transmitted from the network device. The network device includes a hash value generator configured to generate, using a depolarizer, a depolarized key from an initial key (where the initial key is based on contents of the packet and the depolarizer is unique to the network device), and to generate a hash value based on the depolarized key and the packet by using a hash function that is common to all network devices in the network. The hash value may be optionally modified to load balance egress traffic of the network device. The network device selects an egress link or port, such as by determining an index into an egress table based on the (modified) hash value.

摘要： A packet processor is described that performs keep alive message processing using a bifurcated aging table approach. The packet processor includes an aging table, a binding module and an aging daemon. The aging table includes a plurality of records corresponding to a plurality of network links supported by the packet processor. Each record in the aging table is used to track an aging status of a corresponding network link. The binding module associates a received message with a record in the aging table based on information in the received message. The aging daemon scans the aging table, updates the aging status of each network link, and determines that a network link has failed when the updated status for the respective network link exceeds a predetermined threshold. In an embodiment, the aging table includes a base aging table that uses a first number of bits to track the aging status of each network link and an extended aging table that uses a second number of bits that is larger than the first number of bits to track an aging status of a network link on which a number of not received keep alive messages exceeds a threshold.
