Taking a conceptual approach, it describes:
Telecommunications (T1 hierarchy and encoding, QAM modems, DSL, ADSL, twisted pair standards, coaxial cable, fiber optic technology and encoding, SONET protocol), network architecture (comparison of OSI model and TCP/IP suite, peer-to-peer communication, Berkeley (BSD), client server model, sockets, system calls, network topology), wide area networks (ATM, Frame Relay, FDDI, ISDN), local area networks (cyclic redundancy check, HDLC, Ethernet, gigabit Ethernet, token ring), and the Internet (TCP/IP, RIP,OSPF, IDRP, PPP, RTP, address masks, interface layer, SNMP, ASN.1).
Excerpt
Network architecture is an abstract concept. It is also an important one. First, we will develop the concept of a protocol, because protocols are important building blocks of network architectures. In fact, a network architecture is sometimes defined as a system of protocols. Next, we will describe network topologies and show how they relate to network architectures. Finally we will give a more rigorous and complete definition of network architecture.
