Course No.：11120780
Title：Data Communications and Computer Networks
Class Hours/Week: 1.5-1 Credit：2
Category：Elective
Prerequisites：Digital electronic technology
Audience：Undergraduates
Teaching manner：Online and with multimedia
Course objectives and basic requirements:
Students who complete the course should be able to demonstrate the abilities of doing the following:
a) Explain the basic principles and the implementing mechanisms of data communications and computer networks.
b) Explain the conceptions of the network engineering.
c) Build, configurate，maintain and manage the primary network protocol systems.
d) Establish application services based on INTERNET.
Course introduction:
Firstly, the course proposes an analysis model about data communications and computer networks, namely the architecture of computer networks. The course elaborates the definition, arithmetic, analysis model and control strategy of the protocols according to their physical layer, data layer, network layer, transport layer and application layer. The principle and the process of implementation of the current primary Internet network application are introduced in the course, which also describes the developing trend of network technique at last.
Syllabus and lecture schedule:
1. Summary, the classification of network, primary performance index, network architecture (2 class hours)
2. Basic concept of physical layer, digital transmission, channel multiplex, synchronous optical network (2 class hours)
3. Basic concept of data link layer, the control protocols and analysis of data link layer (4 class hours)
4. Summary of LAN, working principle of Ethernet, VLAN, Fast Ethernet, WLAN (2 class hours)
5. Structure of WAN, datagram and virtual circuit, packet forwarding, congestion control (1 class hours)
6. Network interconnection, IP, sub-net designation, control message protocol, routing protocol,
IP multicast, VPN and NAT, IPv6 (6 class hours)
7. Transport protocol, UDP, TCP, flow and congestion control (5 class hours)
8. Application layer, DNS, FTP principle, DHCP, SNMP (1 class hours)
9. RTP, IP phone, multi-protocol label switching, Access network (1 class hours)
