Planning the address space and using DHCP protocol for the allocation of network addresses. Implementation of solutions for traffic routing in the networks and establish connection with other networks: OSPF and BGP. Configuration of redundancy and load distribution on network interface layer: STP, MSTP, and on network layer: HSRP, VRRP. Configuring redundancy and load distribution on application layer:  DNS load balancing, PROXY servers. Monitoring enterprise networks’ performances: Cacti, MRTG. Implementation of VPN service at the network interface layer: PPTP, on the network and application layer: L2TP, IPSec. Configuration of multimedia services in a company computer network: SIP, Asterisk, CallManager, middleware platform. Designing network solutions for multicast traffic. Configuration of virtual machines and network interfaces in Linux and cloud environment: OpenvSwitch, Open Daylight, Open Stack, Mininet. Designing data center of a company: TIA 942. Evaluation of the developed solutions. 

The aim of this course is to enable students for independent designing, realization and using infrastructure and service of computer networks in e-business of a company.
