The next phase of wireless expansion will focus on extending coverage to faculty office areas and conference rooms. This phase of the project will include optimization of existing wireless systems which will improve performance and capacity in all buildings. Optimization is expected to be iterative, as power is optimized new coverage gaps may emerge. The ultimate goal is to improve performance and cover all areas identified for wireless coverage with 802.11n capacity within 18 months.
We will begin construction of a second fiber path from all academic buildings on campus to the data center in Curris business building. Each building except houses will receive 12 additional strands of singlemode fiber. This second fiber path will expand fiber resources at UNI and allow Network Services to protect network service in the event of a core node failure or a data center failure. In conjunction with this project, building network connectivity will have improved fault tolerance with the intention of providing greater resiliency and reduced service impact due to building router failure. We will also improve protection of our Internet service providers and relocate ISP demarcation to secure data centers.
In response to requirements to increase bandwidth to support protecting UNI data assets, support server virtualization, and improve security the network equipment in UNI data centers will be upgraded to support 10 gigabit connectivity. This project will also improve network fault tolerance, reduce impact of scheduled maintenance on service, and enable storage and voice convergence. Many systems will be upgraded prior to Aug 2013, remaining systems will be upgraded by Jan 2014. New firewall systems will be installed July 2013 and phased into service over the following 15 months.
Our UNI campus network, which spans every academic building on campus, is migrating to a new network topology. This change is being driven by several factors chiefly the scheduled demolition of Baker hall, which is currently the center of our fiber topology. This migration will free scarce IP addresses to enable our next generation network refresh designed to improve network performance, reliability and security. The first phase of the project is to coordinate the subdivision of the UNI campus subnet. In conjunction with the subdivision we will coordinate migration of devices in the lower half as well as assign a new gateway address and subnet mask to all campus network devices. The second phase involves migrating campus buildings to dedicated subnets begins in May '12. In conjunction with these efforts ITS is installing and migrating to a new fiber plant, in preparation for the Baker demolition. Additional details and resources concerning the project can be found on the ITS Network Engineering support site. Update 6/1/13, several buildings remain to move CBB, BAK, East Bartlett.
