50 Halloween 2001CNRC50 Closets Electronics Network switch. UPS.

51 Halloween 2001CNRC51 A Core Router Cisco Catalyst 6509 Redundant MSFC/2 router w/Supervisor II MSM->MSFC->MSFC/2 Concentrates several building hubs with gigE uplinks. Dual gigE uplinks to dual core L2 6509s Dual Power supplies w/dual UPS. Some generator backup (working on more).

52 Halloween 2001CNRC52 A Core Switch Catalyst 6509 Two of them at opposite sides of campus One’s currently on generator power Eight gigE uplinks from the eight switch/routers We might put routers in these too.

53 Halloween 2001CNRC53 Older Network & Routers FDDI backbone ATM OC-3 cloud Only thing left is two WAN DS-3 links. 7507s for WAN, FDDI, ATM Dual 100baseFX into core (for now) Temporarily gigE (due to bug in port channel support between 7507/6509).

54 Halloween 2001CNRC54 Routing Protocols Interior routing: EIGRP Would like to stop being Cisco zombies and run OSPF one day. Exterior routing: BGP vBNS, Abilene NYSERNet schools & routers Applied Theory, Uunet, RCN All 6509 routers speak iBGP w/egress routers

55 Halloween 2001CNRC55 Conversion “Issues” Had to convert right-angle 25pr telco connectors to straight-in! Had to convert 15A outlets to 20A. Long vs. short-haul GBICs. Expensive MM to SM conditioning cables. Pulled a lot of new SM fiber. Fiber testing: Plug and Pray.

56 Halloween 2001CNRC56 Conversion “Issues” MSMs vs. MSFCs vs. MSFC/2s MSM: limited ACLs; No Appletalk routing. MSFC: too little RAM to run iBGP. DoS caused by unrestrained fast hosts on a fast network (p2p apps, etc.). Shaping outbound dorm traffic to 50 Mbps cost of Smartnet service contract.

57 Halloween 2001CNRC57 Outline A little about Columbia Wide area Internet[2] connections Metro area inter-campus network Main campus network Gigabit Ethernet experience Advanced networks and applications Future plans

58 Halloween 2001CNRC58 Advanced Networks & Applications Video Conferencing Voice over IP Multicast Wireless b IPv6 CDNs Network Management

59 Halloween 2001CNRC59 H.323 video conferencing Internet2 Commons just starting up. Member of Videnet (www.cavner.org) Zydacron Z340, Z360 & COMstation. Cisco (Radvision) ISDN (H.320) gateway. Tandberg Codec 5000/RADvision VIU-323 Polycoms just work.

60 Halloween 2001CNRC60 MPEG2 conferencing Litton CAMVision 2 Full D1 720x480 video 48 kHz 384 kbps stereo audio 15.4 Mbps Amnis, Minerva, VBRICK

61 Halloween 2001CNRC61 Voice over IP Have a few Cisco phones. Telecom dept is deploying Siemens phones on a very limited basis. SIP (Session Initiation Protocol) is taking over the world. Switching our Cisco phones over to SIP cuz it’s cool and runs on a real OS.

62 Halloween 2001CNRC62 Multicast CGMP/IGMP snooping on Catalysts Cisco/Borg Collective at work. PIM sparse mode. MBGP, MSDP w/Abilene, vBNS, NYSERNet, Cornell. IGMPv3 & SSM soon. Main apps: Norton Ghost, Video

63 Halloween 2001CNRC63 Multicast A few conferences so far IPTV 2.0 and Osprey-100 card (H.261) In parallel with RealProducer G2. IPTV 3.0 and an Optibase MPEG2 D1. Used for several music events (MPEG1) and Virtual Internet2 Member Meeting 10/2-5. Does MPEG2 but viewers are licen$ed.

64 Halloween 2001CNRC64 Multicast Would rather be using a real operating system. Many equivalent apps that use multicast but that don’t work with each other (Real, WMT, vic/vat/IPTV, videocharger, Litton, etc.) Need to learn a lot about video production.

65 Halloween 2001CNRC65 Wireless b Central outdoor campus spaces covered. Putting them in lounges, libraries, classrooms, Lerner, and so on. Roof-to-roof applications for backhoe protection and near-campus buildings. Linked NYAM across Central Park.

66 Halloween 2001CNRC66 Campus bldgs: Wireless LANs IEEE b deployed on small scale today. Not as fast as wired Ethernet. Applications: Outdoors. Conference rooms. Lecture rooms.

67 Halloween 2001CNRC67 IPv6 IPv6 via NYSERnet/Abilene IPv4 tunnels. Global /48 assigned by NYSERNet. EUI-64 addressing (MAC address) Wireless subnet CS, AcIS subnets More as requested Bind9 IPv6 on curta.cc.ip6.columbia.edu

69 Halloween 2001CNRC69 Performance Management Surveyor NLANR Active Measurement Probe (AMP) NLANR PMA (OC3mon) – optical splitter Cricket Sampson Aperserv

70 Halloween 2001CNRC70 Performance Management Policy routing Forcing non-I2 connector traffic to I1. CS I1 vs. I2 comparison project. QoS Shaping of outbound commodity traffic. Fair queuing. Security NBAR attempting to label Code Red, etc.

71 Halloween 2001CNRC71 Outline A little about Columbia Wide area Internet[2] connections Metro area inter-campus network Main campus network Gigabit Ethernet experience Advanced networks and applications Future plans

72 Halloween 2001CNRC72 Future Plans New Construction K-8 th /Bway New School of Social st /Morn Expansion to apartments? Many are already passed by our fiber. Several have 1 st floor networks for offices. Fiber routes pass UTS, MSM, I-house. Fiber routes to academic buildings are via apartments

73 Halloween 2001CNRC73 NYC Dark Fiber Project NYSERNet built & owned or leased. Fiber ring around Manhattan, parts of Bx. Cost target: <= current OC-3 local loops. 36 initial potential connectors Universities, Hospitals, Museums, NYPL Vendor-neutral ISP colo hotel(s) possible Even more important post-9/11.
