1 Alternative Backbone Technology Presented by: Joseph Piscetta, William Hoffman, John Finneran, Bonnie Judge, Shawn McCaffrey, Andrew Jobs, Shane Behmer

2 Alternative Backbone Technology Villanova University plans to replace existing campus telephone system Withdrawn from market – End of Life 5 years ago Parts are difficult to obtain Circuit Switched Network Establishes a dedicated connection between two users before they may communicate Packet Switched Network Packets are routed between users over data links shared with other traffic Optimizes the use of bandwidth available in a network

3 Current Data Network New Technologies being Evaluated Would allow phone calls to be delivered over a packet switched network like our data network They require that the data network have a high degree of fault tolerance The current data network does not have the degree of fault tolerance that we need The University needs to improve its network’s redundancy before any upgrades to the phone system are made

4 Alternate Path Commuting into New York City Many alternate paths Used Simultaneously Active/Active Load Balancing Resembles a Packet Switched Network Minimizes time it takes to pass through the network Increases the strength of communication

5 Wireless! Our solution calls for the use of Wireless Technology Wireless technology will enable Villanova University to gain the redundancy needed to support a Packet Switch Network Is this technology feasible for Villanova University?

11 Wireless Technologies Radio Frequency (RF) Uses radio waves to send a signal. Not affected by normal weather patterns. Can use reserved frequency. Signal needs to be tightly focused. Free Space Optics Uses lasers to communicate between two points. Subject to interference by rain or snow. Line of sight more of an issue.

12 Radio Frequency Bridgewave GE60x Operates on 60GHz Unlicensed Frequency Highly secure, narrow antenna beamwidths $24,900 per link with installation Used as Primary Campus Link The only problem I have encountered was a severe snowstorm which caused the link to go down but I imagine that would be the case with any such system. Seattle had the rainiest season on record this past November but that did not affect the link.- Clint Dicus, Network Engineer, Seattle University GigaBeam WiFiber Operates on 80GHz Licensed Frequency $50,000 per link with installation Used at Dartmouth as primary hospital link. GigaBeam's support has been phenomenal. They do not want to see any hiccups with their service and are out here if there is one. If there is an occasional outage is it very brief and due to very bad weather. – David Bucciero, Director of Dartmouth Technical Services

13 Free Space Optics MRV Communication- TereScope 5000 MRV was the early leader in FSO with 6000 installed links. $32,000 per link, including installation Used at schools such as: New York University UCLA Canon- Canobeam DT-130 Fifteen years in FSO optics, $50 billion dollar company. Installation and maintenance arranged by Canon. Due to lack of information sharing, we were unable to fully evaluate Canon

14 Conclusion AHP Model Multiple wash criterion Lack of separation between alternatives Wireless vs. Wired Cost of digging vs. wireless installation No longer an emerging technology Good feedback & references
