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• Withdrawn from market End of Life 5 years ago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

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 networks
  redundancy before any upgrades to the phone
  system are made

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?

Analytical Hierarchy Process

• Goal Create a reliable, low-cost point to point
  redundancy system efficiently and effectively
• Evaluation
• Technological Architecture
• Cost
• Implementation
• Training
• Vendor Viability

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.

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 causedthe link to go down but I
  imagine that would be the case with any
  suchsystem. Seattle had the rainiest season on
  record this past November butthat 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

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
