Abstract: 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.

Abstract: A method includes classifying signaling messages to be transmitted from a mobile communication terminal 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. 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.

Abstract: A method includes, in a mobile communication terminal, detecting degradation in communication quality between the terminal and a serving base station 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 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.

Abstract: A meter module for use in a network device comprises conformance circuitry configured to: access a first memory device storing a conformance indicator that indicates whether a permitted rate of packet traffic has been exceeded, and classify packets received at the network device based at least in part on the conformance indicator. Sampling circuitry is configured to, responsively to the conformance circuitry classifying the packets: sample events associated with at least some of the received packets, and generate indicators of the sampled events. Update circuitry is configured to: access a second memory device, slower than the first memory, to update a number of tokens stored in the second memory device, and access the first memory device to update the conformance indicator when the updated number of tokens indicates that the permitted rate of packet traffic has been exceeded.

Abstract: In a method for processing network packets, a network packet is received at an ingress port. Before the network packet has been completely received at the ingress port, a first data structure representing the network packet is generated based on a received first portion of the network packet, and the first data structure is processed at a packet processor of the network device. Processing the first data structure includes making a forwarding decision for the network packet. A second data structure representing the network packet is generated and, after the network packet has been completely received at the ingress port, at least one or more non-forwarding operations are performed with respect to the network packet using at least the second data structure.

Abstract: 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.

Abstract: In a method for processing packets in a network device, a first packet is received at a first port of the network device. A first set of bits, corresponding to a first set of bit locations in a header of the first packet, is extracted from the header of the first packet. A first set of processing operations is performed to process the first packet using the first set of bits. A second packet is received at a second port of the network device. A second set of bits, corresponding to a second set of bit locations in a header of the second packet, is extracted from the header of the second packet. A second set of processing operations is performed to process the second packet using the second set of bits.
