摘要： In a memory device having a set of memory banks to store content data, at least two requests to perform respective memory operations in a first memory bank in the set of memory banks are received during a single clock cycle. It is determined that one or more of the at least two requests is blocked from accessing the first memory bank. In response to determining that the one or more of the at least two requests is blocked: redundancy data associated with the first memory bank and different from content data stored in the first memory bank is accessed, and, without accessing the first memory bank, at least a portion of the content data stored in the first memory bank is reconstructed based on the redundancy data associated with the first memory bank. A first requested memory operation is perfomied using the content data stored in the first memory bank, and a second requested memory operation is performed using content data reconstructed 1 ) without accessing the first memory bank and ii) based on the redundancy data associated with the first memory bank.

摘要： A network address associated with a packet is obtained at a search engine of a network device. The search engine includes a plurality of Bloom filters that represent prefixes of respective lengths in the routing table. Respective Bloom filters are applied to respective prefixes of the network address to determine a set of one or more prefixes for which a match potentially exists in the routing table. A number of accesses to the memory are performed using prefixes in set of prefixes, beginning with a longest prefix and continuing in decreasing order of prefix lengths until a matching entry is found in the routing table, and routing information for the packet is retrieved. If the number of performed memory accesses exceeds a threshold, the routing table is adapted to reduce a number of memory accesses to be performed for subsequent packets associated with the network address.

摘要： A packet being processed by a network device is parsed by a programmable processing unit executing computer readable instructions stored in a non-transitory computer readable storage medium. Parsing the packet includes identifying one or more protocol layers within a header of the packet, identifying respective locations of protocol headers within the header of the packet, and providing the respective identified locations of protocol headers within the header of the packet to a hardware key generator block. A lookup key corresponding to the packet is generated by the key generator block using the respective identified locations. Generating the lookup key includes extracting, using an identified location of a protocol header, one or more fields from the corresponding protocol header. The lookup key is provided to a lookup engine. A lookup operation with respect to the packet is performed by the lookup engine and based on the lookup key.

摘要： In a method for processing network packets, a network packet is received at an ingress port. After at least a first portion of the network packet has been received, but before the network packet has been completely received, a first data structure representing the network packet is generated based on the first portion, the first data structure is processed, and the network packet begins to be selectively forwarded to a first one or more egress ports, or selectively not forwarded to any egress port, responsively to processing the first data structure. A second data structure representing the network packet is generated and, after the network packet has been completely received, the second data structure is processed, and the network packet is selectively forwarded to a second one or more egress ports, different from the first one or more egress ports, responsively to processing the second data structure.

摘要： In a method for performing an exact match lookup in a network device, a network packet is received at the network device. A lookup key for the network packet is determined at least based on data included in a header of the received network packet. A hash function is selected, from among a plurality of possible hash functions, at least based on a size of the lookup key, and a hash operation is performed on the lookup key using the selected hash function to compute a hashed lookup key segment. A database is queried using the hashed lookup key segment to extract a value exactly corresponding to the lookup key.

摘要： A method includes, in a mobile communication terminal (24), detecting degradation in communication quality between the terminal and a serving base station (28) during establishment of a call via the serving base station. During the establishment of the call via the serving base station, the terminal searches for an alternative base station (28) that is suitable for establishing the call. Upon finding the alternative base station, a switch is made to establish the call via the alternative base station.

摘要： A method includes classifying signaling messages to be transmitted from a mobile communication terminal (20) into one or more classes, wherein each class corresponds to a respective event relating to the terminal and specifies the signaling messages that become irrelevant when the event occurs. The signaling messages are queued for transmission in a queue (40). In response to detecting an occurrence of a given event, the irrelevant signaling messages are removed from the queue based on the class specifying irrelevant signaling messages corresponding to the given event.
