Introduction to TCP/IP
- Basic notions. TCP/IP architecture. Networking standards.
- Services and protocol. Communication mechanisms.
- Connection-oriented versus datagram communication.
- Client-server model.
- RFCs. What is IETF?
IP protocols
- Using the physical networks. From Ethernet to SDH/SONET.
- Network addresses.
- Address classes.
- What a netmask is. How to use it.
- Routing principles. Routing tables. Static versus dynamic routing.
- Subnetting. What for. How to implement them.
- ICMP protocol. How to use it.
- The ping and tracert commands. How to use them.
- DHCP protocol. How to implement it.
Hands-on work
Setting up a basic IP network with Ethernet and Windows or Linux workstations. Using ICMP, observing traffic. Setting up DHCP servers and clients. Setting up a DHCP relay.
IP on Lan/Man/Wan
Transport layer : TCP and UDP
- Application addresses: Transport port numbers.
- TCP: Connection-oriented transport protocol. When to use it.
- Setting up a connection. Numbering scheme, acknowledgement and retransmission, Flow control.
- UDP: Connectionless transport protocol. When to use it.
- The socket interface. Network application design principles.
Hands-on work
Observing TCP-based transfers and UDP-based transfers.
Interconnecting IP networks
- Routers. Functions implemented on a router. Translation addresses and/or port numbers (NAT, PAT).
- Comparing routers with switches.
- Routing. Dynamic versus static routing. Interior Gateway Protocols (IGP: RIP-distance vector routing, OSPF-link state ro
- IP switching. How to make IP routing faster: from proprietary tag switching techniques to MPLS.
Hands-on work
Designing and implementing several IP subnetworks. Choosing netmasks, setting up routers. Using RIP and OSPF.
TCP/IP applications
- Domain Name System. Design principles. How to set up and test a DNS server.
- File Transfer Protocol. How it works. Security aspects.
- Another file transfer protocol: Trivial File Transfer Protocol. How it uses UDP.
- WWW HTTP and related techniques.
- Mail related protocols: Pop, Imap, Smtp. How to avoid Spam.
- Remote access protocols: Telnet, rlogin, ssh. What is SSL.
- Sharing resources: NFS, SMB and other protocols.
- Multimedia applications.
Hands-on work
Observing FTP transfers from a command-line client or a browser. Comparison with TFTP transfer. Using Telnet and HTTP.
TCP/IP network management
- What is a network management system: manager and agents.
- Using SNMP (SNMP V1, V2c, V3. SMI. MIBs).
- Analysis tools.
Hands-on work
Monitoring traffics. Basic SNMP use.
Towards IPv6
- Why to get ready for IPV6.
- Adresses and adressing structure.
- Statically versus dynamically assigned adresses. Using DHCPv6.
- IPv6 migration : using dual stacks, tunnels.
Hands-on work
Setting up the IPv6 stack on a Windows workstation. Assigning static adresses. Observing Iv6 packets.
TCP/IP security
- What is IPSec.
- Building VPNs.
- Firewall, proxy-servers, NAT and PAT.
