In the last RTFM we saw how IP packets are transmitted across the network. Here, we tackle Ethernet and see how packets are encapsulated and used. To explain fully the way in which IP packets are ...

it is essential to learn about the protocol layers (see OSI model). The IP layer 3 breaks apart the data being transmitted into variable length packets, known as "Ethernet frames," up to 1,500 ...

Comparing MACsec and other secure communication protocols As shown in Figure 1, MACsec operates at the data link layer on Ethernet frames and can thus protect encapsulated payloads from upper layer ...

Consequently, the 10GbE test functions related to switching and routing are similar to those on more mature protocols such as POS (Packet over SONET/SDH) and lower speed Ethernet. This includes the ...
