Viewing Endpoints
An endpoint is the place where communication ends on a particular protocol. For instance, there are two endpoints in TCP/IP communication: the IP addresses of the systems sending and receiving data, 192.168.1.5 and 192.168.0.8. An example on Layer 2 would be the communication taking place between two physical NICs and their MAC addresses. The NICs sending and receiving data have addresses of 01:00:5e:00:00:16 and 01:00:5e:01:01:06, making those addresses the endpoints of communication. You can see a graphical representation of this concept in Figure 5-7.
