LAN UPGRADE

IRKUT CORPORATION

GOALS AND OBJECTIVES

  • BUSINESS OBJECTIVE

    To ensure uninterrupted network operation and guaranteed availability of business applications.

  • IT OBJECTIVE

    To optimize of the use of cable systems and active network equipment; to ensure equipment compliance with new service quality requirements for the transmission of various types of traffic; to increase the LAN’s manageability and fault tolerance.

SOLUTION

  • The network is built on active network equipment Nortel Enterprise Solutions (part of Avaya since December 2009). ERS 8610 switches form the network core.

IMPLEMENTATION

The modernized LAN is based on a modular principle which ensures the scalability of the system. The network architecture is designed using double-center star topology, which eliminates single points of failure, given that equipment at the network core level and server connection level is redundant on a 1+1 principle.


Two server farms were implemented using Gigabit Ethernet technology to connect primary information resources and backup data processing centers. The server farms were connected to the core using 10Gigabit Ethernet and SMLT technologies. The use of SMLT technology makes communication between data centers possible at the second level of the ISO OSI model, enabling the creation of distributed systems clusters.

PROJECT RESULTS

A modern, scalable network infrastructure, enabling the interaction of about 4500 users. The use of new generation active network equipment provides the opportunity for further systems development, so as to better implement services, and ensures durability in an environment prone to changing information security requirements.

CUSTOMER REVIEW

This project made it possible for us to increase our LAN’s fault tolerance and provides us with the ongoing possibility of developing new IP telephony and video conferencing-based telecom services to keep in step with improvements in the quality of data transmission services. The solution enabled us to entirely rid ourself of operational failures at both the core and network distribution levels (i.e. network equipment based failures), given that there is now no single point of failure.
