Fy ‘08 NETWORK PLANNING TASK FORCE First Strategy Discussion 10.1.07
NPTF Meetings – FY ‘08 • 1:30-3:00pm in 337A Conference Room, 3rd floor of 3401 Walnut Street • Process • Intake and Current Status Review – July 16 • Agenda Setting & Discussion - September 17 • Strategy Discussions - October 1 • Security Strategy Discussions - October 15 • Strategy Discussions - October 29 • Prioritization - November 5 • FY’09 Rate Setting – November 19
Proposed NPTF Meetings – “FY ’09” • February 18-Operational review • April 21- Planning discussions • June 2- Security strategy session • July 21-Strategy discussions • August 4- Strategy discussions • September 15- Preliminary rates/security • October 6- Strategy discussion • November 3- FY’10 Rate setting
Today’s Agenda • Strategy Discussions • Next Generation PennNet • UPS for network electronics • Integrated Communications • Intrusion-Detection
Next Generation PennNet-Gig Connectivity & Building Redundancy • Goals • Gig enabled closet electronics • Gig to every building • Redundant Gig connectivity • Current Status • Approximately 60% of switches 10/100/1000 enabled • By the end of FY ’08, most switches will be 10/100/1000Mbps • 62 buildings with Gig Ethernet
Strategic Approach: NGP • Diversify the PennNet Routing Core • Move out of College Hall (Largest Single Point of Failure) • Construct 5 Network Aggregation Points (NAPs) • Redundant High Speed Connectivity between NAP locations • Highly Available Core Network Infrastructure • Relocate Campus Building Uplinks to Local NAP • Provide High Speed Uplinks to Buildings (where infrastructure can support this now, single-mode fiber/conduit build outs sometimes necessary) • Provide Redundancy Uplinks to Campus Buildings • Five Connectivity Models • Based on Building Criticality (University Business) • Number of User Connections • Infrastructure Availability
Diversify PennNet Routing Core • Five NAP locations completed and in operation • NAP locations have redundant and diverse 10 gig feeds. • NAPs connect local buildings that have fiber and pathway. • 62 buildings have gigabit Ethernet service • College Hall node room will house a core router for next two years (until all NAP to building feeds are in place) • Will reduce catastrophic disaster recovery time from 2 weeks to under 2 hours. • Will provide infrastructure foundation for next generation data, voice and video services. • Eastern NAP feasibility study pending construction timeline.
Building Connectivity Models 1 & 2(Dual Feeds to separate NAPs, each with either diverse or overlapping pathways)
Building Connectivity Model 3 (Each Building has 1 uplink to a separate NAP and one link to each other.)
Building ConnectivityModel 4 (Building has 1 uplink to each Building Entrance Router in the local area.)
Building Connectivity Model 5 (Building has 1 uplink to a Building Entrance Router.)
Building Connectivity Model 5a (Building has 1 uplink to a Building Entrance Router with dual feeds.)

Redundancy (UPS) • As we move towards data, voice and video IP-based systems and services that all rely on electrical power, how much protection should we do and can we afford? • We have back up generators and UPS in the 5 NAPs. So theoretically they should not go down. • Building power is not 99.999 from Peco/Facilities. • While we do not have solid historical data, we began recording data on power outages beginning in March 2007. • Since March 21,2007 the campus has had 52 hours of outage due to power loss in 36 buildings. (Not including a 64 hour outage to Nursing LIFE) • Generally, outages are either very short (blip) or 1+ hours.
Redundancy (UPS) • It costs about $2700 per location to install UPS (assuming the UPS has 25 minutes of battery time and no other wiring closet work need to be done). • Cost of $1100.00 per 15 minutes additional battery time • Rough ongoing costs would be approximately $900/yr per location. • N&T manages over 600 wiring closets on campus • Annual cost would be about $540K
Redundancy (UPS) • Alternatively, we could just do UPS on the building routers. • There are only 100 of these locations. • Without UPS, a short electrical blink causes them to reboot, forcing a 5-10 minute outage. • This would mean for that duration, there would be no services that require the network including phones. • Annual cost $90k • Are you interested in this? Is it worth spending this much to protect against 25 minutes of outage?
Integrated Communications (IC) • IC involves integrating several communications applications toward improved productivity for staff, faculty and students: • PennNet Phone and Voicemail • Instant messaging • Desktop video • Linking these applications together, and to University information (online directory, calendars, etc) puts more control in the hands of our user community • It also allows user communication preferences to be taken into account.
PennNet Phone • Goals • To convert 25,000 analog voice customers to Integrated Communications (VoIP, Voicemail, etc.) over the converged IP network with added functionality and lower costs in 5 years or less. • Status • We currently have about 1400 PennNet Phone users. • Redundant servers and gateways • Full service monitoring 24x7 • New feature releases about twice a year • New phone equipment being rolled out by early 2008.
PennNet Phone • Issues • We have had some long-term problems with the PRIs from Verizon and the Cisco gateways that have caused known problems with transferring some calls, some caller ID, etc. • Next steps • We believe we have the PRI problems resolved. • We tested the new gateway code yesterday. • The new code release comes out in late October. • If all goes well, we could have improved call transfers in production in November.
Instant Messaging • Goals • Users at Penn report that they are using Instant Messaging (AIM, Yahoo Messenger, Skype and Google Talk) today for business purposes. • Our goal was to provide them with an alternative that • Provides improved privacy and security • Is able to make use of Penn identity information • Can be integrated with other Penn communications elements
Instant Messaging • Status • The same open standard, open source technology used by Google Talk, "jabber" (based on the XMPP protocol family) is being deployed and used in a pilot mode at Penn today • It provides controlled data path (need not leave campus when two on campus users chat) • It provides identity assurance (uses Penn's authentication system, and Penn's naming scheme) • It has so far proven to be low cost to operate and highly reliable. • Next steps • Pilot to a larger audience over the next 3-4 months • Full rollout at no cost to current PennNet phone and email customers by end of FY’08.
Voice mail • Goals • Roll out version 1.0 of new voicemail in early 2008 (possible late January). • Key reasons for change • Today’s Octel Voicemail system is old and expensive to support (vendor EOL/EOS) • It does not have good disaster recovery capabilities • In a failure, we could be out for at least 12 hours • Message recovery would be incomplete. • The new system can recover rapidly with very complete data • The new system is designed for the new PennNet Phone service to be used throughout Penn in the next few years • A migration by all users to the new voice mail system now brings us back to "one voice mail community"
Voice mail Differences • There will be differences in features and functionality • In some cases, the new voice mail system will be less feature rich • But it will allow PennNet Phone users some very advanced online access to messages and features • Web access to settings • Both telephone and email access to messages
Voice mail Timing • New voicemail is in production use now for 1400 PennNet Phone users • New voicemail is in pilot now for 100 campus users of traditional phones • For most traditional phone users, rollout is being targeted for early 2008 (possibly late January) • For advanced voicemail applications, migration will take place in late spring or early summer CY2008 • eg., Menus, Transfer Mailboxes, Listen-only mailboxes
Desktop Video • Goals • Easy, low cost desktop video conferencing for when audio or IM is insufficient • Status • No work being done towards a Penn service. But desktop client tools are maturing. • Issues • Maturity, complexity, cost • Next steps • Wait a little longer
Intrusion Detection (Perimeter & PennNet Core) • We deployed Arbor Networks peakflow in 2005 • A network management tool that provides some ID functionality for PennNet perimeter and core. • We use it for a wide range of analysis, including attack signatures, but also traffic characterization and ISP peering analysis. • We are able to share info across institutions so that we can recognize an attack before it reaches Penn. • Upgrades are mostly software which is covered by our current contract.
Intrusion Detection(Local level/subnet) • Host-based intrusion detection is available today for every major operating system • ISC is committed to having a strategy for local intrusion detection systems, as well as recommendations and product offerings before network-based IDS becomes required in any security policy. • It is likely that this would be in FY’09. • We are currently looking at a few products • Tipping point (meeting with them tomorrow) • Arbor - Peakflow x • Snort-widely deployed open source IDS • Bro-open source IDS developed at LBNL by Dr. Vern Paxson, a noted TCP/IP researcher. • A local IDS could be deployed alongside, and access “mirrored” traffic from, a building entrance device.
