LOS ANGELES—This is the second installment of a contribution from Jim DeFilippis on SDI versus IP. For Part 1, see “Which Switch is Which?” The second tale-of-the-tape issue is delay or latency. There ...

Interconnect standards such as PCI Express, Hyper Transport and Rapid IO have several common features such as packet based transmission, flow control for buffer space management, data integrity checks ...

The use of IP for audio and broadcast transport applications has gained increasing attention as the quality of service (QoS) of packet switched networks continually improves. The lure of reduced costs ...

Packet queues are a core component of any network stack or device. They allow for asynchronous modules to communicate, increase performance and have the side effect of impacting latency. This article ...

It’s a common benchmarking practice to take multiple measurements of throughput or latency, each using a different packet size. There’s no one right answer as to which packet size represents the ‘best ...

Breaking an IP datagram (packet) into pieces in order to be sent across a transmission link with a frame size smaller than the datagram. Performed in a router, the header of the original IP packet is ...

The purpose of the network layer is to help route messages between different local networks. Central to this layer is the concept of exclusive network addresses, where every terminal connected to the ...
