In the last issue we started following a packet's journey from the wire up to the higher levels of network stack processing. We left the packet at the end of layer 3 processing, where IP has ...

Was wondering if anyone could shine some light on the behavior of packets, is the payload (MTU) of a jumbo frame always 9000 - or up to that value. + What happens when it hits the lower MTU Emulex ...

The current IP address scheme of 32-bit words is fast becoming inadequate. It would appear that 2 32 = 4 294 967 296 combinations of addresses should be enough for everybody, but in practice this is ...

Often we discuss errored packets that are dropped without understanding the underlying techniques that determine why the packets are discarded. There are checks for errors at several protocol layers.

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 ...

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 ...
