Abstract: A method for network hardware table management includes: obtaining, by a network device table manager of a network device, a first feature table entry of a first feature table, where the first feature table entry comprises a first prefix and a first action to take for a first feature; obtaining, by the network device table manager, a second feature table entry of a second feature table, where the second feature table entry comprises a second prefix and a second action to take for a second feature; making a first determination that the first prefix and the second prefix include a common portion and that the common portion is an entirety of each of the first and second prefixes; and in response to the first determination, adding a combined feature table entry to a combined feature table.

Abstract: Methods, systems, and computer readable mediums for network hardware table management including obtaining, by a network device table manager of a network device, a first feature table entry published by a first feature; obtaining, by the network device table manager, a second feature table entry published by a second feature; making a first determination that the first feature table entry and the second table feature entry each comprise a common prefix; and based on the first determination, adding a first combined feature table entry to a combined feature table, the first combined feature table entry comprising the common prefix, a first feature action of the first feature table entry and a second feature action of the second feature table entry.

Abstract: Methods and systems are described for comparing values using an associative memory. An associative memory lookup is performed based on a key that comprises a first number, a second number, and a third number. The associative memory includes sets of mask rows that are configured such that the associative memory returns a result of true when the sum of the first number and the second number is equal to the third number. The result of the associative memory lookup is outputted. The associative memory configured in this manner may be used, for example, by a packet forwarding device to perform a zero-value boundary condition check or packet sequence check.

Abstract: The present disclosure relates to a reflector antenna arrangement comprising at least a first reflective metal surface and a signal feeding arrangement transition that is adapted to receive a signal feeding arrangement that in turn is adapted to transmit and/or receive electromagnetic radiation via the first reflective metal surface. The reflector antenna arrangement further comprises a common dielectric body comprising at least one dielectric material, to which common dielectric body the first reflective metal surface is attached in a fixed relation to the signal feeding arrangement transition with a certain distance between them such that said transmitted and/or received electromagnetic radiation at least partly is arranged to propagate through at least a part of the common dielectric body.

Abstract: The present invention relates to the field of arrangements in reflector antennas, and in particular to that part of this field that concerns reflector antennas that include subreflectors. The invention is concerned chiefly with an improved subreflector (5b) which when used in a reflector antenna (1) enables the antenna to obtain a radiation diagram with high suppression of side lobes in both the H-plane and the E-plane. The reflective structure of the subreflector (5b) includes at least two mutually different geometries (15, 17) that have been configured specifically to obtain radiation diagrams with good suppression of side lobes in both the E-plane and the H-plane.
