Internet Protocol
- IP Addressing
- IP addressing requires more thought and effort to learn as compared with data-link addressing
- IP defines flexible options of how addresses must be grouped together
- IP hosts include every traditional PC, every
phone, and every tablet computer
- IP Routing
- IP routing functions relies heavily on the other other two functions, using routers, the
LANs and WANs connected to the routers, and the IP addresses that identify the hosts
- The routers have the responsibility to know to know the
locations of all the host IP addresses in the TCP/IP network
- IP hosts and IP routers forward (route) IP packets through a TCP/IP network
- Layer 3
Functions
- IP routers have an IP routing table with useful routes for IP routing to work
- Most routing protocols exist as TCP/IP standards as defined in various RFCs
- Routers build their IP routing table in two ways, through
static configuration or with dynamic routing protocols
- TCP/IP
Model
- The TCP/IP network layer completes functions in a TCP/IP network
by defining how to forward packets betweek any two hosts
- The TCP/IP network layer delivers data from end to end through the network
- Every new term, standard, protocol, and address is
related to some physical layer or data link layer
