| 9.1.6 | Network layer

The Network Layer provides connectivity and path selection between two end systems (original source and final destination) that may be located on geographically diverse networks. Network Layer addressing provides addressing for the original source address and the final destination address, i.e. in TCP/IP these are the IP addresses. These addresses do not change along the path. Examples of Network Layer protocols include: IP (Internet Protocol) Novell's IPX (Internetwork Packet Exchange)
