CAnet 4 Plans

• Many universities deploying campus CEF networks
  and extending ROADM into campus
• UBC, Carleton, McGill, UoToronto, OttawaU,
  UdMontreal
• ROADM network allows us to place all active DWDM
  gear at campus
• Core of network is solely optical
• We are expecting big demand from individual
  researchers and departments for their own 10G/40G
  circuits directly connected to wavelengths on
  CAnet 4
• We also planning wavelength swaps with NYSERnet,
  MiLR, ORANO, NLR and others
• We only charge incremental costs for wavelength
• 20K per year per end for 10G
• 30K - 40K per year per end for 40G
• UCLPv2 software now available to allow users to
  manage their own lightpath topology both on and
  off campus

Problem

• Universities and Telephone companies face the
  same problem of small number of heavy users
  consuming expensive Internet bandwidth
• University solution is to cap bandwidth from
  dormitories and/or block types of traffic
• Telecom solution is to build a two tiered
  Internet or doing volume capping
• A high speed un-congested channel for the telco
  traffic particularly aimed at carrying video
• Universities can play a leadership role in
  piloting new last mile (hundred feet)
  architectures that address problems of
  dormitories
• May serve as possible model for telcos
• University students are ideal early adopters and
  were instrumental in diffusion of the Internet
  throughout larger community

7
One possible solution

• Following is example of one possible solution
• There may be others- this is not intended to be
  definitive or exclusive
• Work with a few universities on a small number of
  pilots where interested students can lease or
  control dedicated fiber/copper to university colo
  point
• They can directly peer with other students in the
  dormitory across a white light switch or user
  controlled VLAN switch and/or
• Connect to service providers of their and/or
  setup point to point user controlled VLANs to
  other students across Internet 2, CAnet 4,
  GLORIAD, GLIF, SURFnet, i2Cat, KREOnet, etc
• Primary application would be collaborative video
  such as YouTube and/or CineGrid

What is user controlled networks?

• Tools that allow user to do their own layer 1
  layer 2 configuration and management e.g.
• University of British Columbia transmorgifier
• HEAnet (Ireland UCLP deployment) links VLANs with
  MPLS tunnels
• Not a new idea many overlay networks work like
  this e.g. Skype, Kazaa, BitTorrent
• In essence we want to extend peer to peer overlay
  network to physical domain
• By extending user control to physical network,
  user can control their own routing and bandwidth
• Big advantage is that provider of physical
  facility cannot do packet filtering or blocking
  at layer 1
• UCLP in addition allows users to manage virtual
  routers, switches, server nodes so that they can
  do their own routing and topology
• UCLP is a generic peer to peer network management
  tool for creating underlay networks as opposed
  to overlay networks

return signal

Passive Optical Splitter or UCLP Ethernet switch

Service provider can be several km away
University Colo Node
Active laser optional CWDM on student computer
User Controlled or Owned Fiber

Policy Neutral University Colo

• Two possible models
• Simple splice case that contains RPON only direct
  mapping of all fibers from student doms to all
  service providers fibers or
• Cabinet that also contains optical OXC or
  Ethernet switches (each provider has their own
  OXC) to optimize service providers fiber
  utilization
• Customers laser signal is split with RPON or
  across Ethernet switch to all service providers
  in the colo
• PON technology allows 16, 32 and 64 split
• Split ratio determined by power of customers
  laser and distance
• LX GBIC 10 kms about 200 in small quantities
• Customer contracts with service provider of their
  choice
• Selected Service provider then provides return
  signal to customer from their CO
• Service providers in colo agree to use different
  colored lasers for return signal
• One service provider can be a lightpath across
  GLORIAD/GLIF

11
Advantages for student

• One time very small cost for UNLIMITED bandwidth
  forever to university colo
• Cross connect to service provider of their choice
  or research network(s)
• NO or very low monthly Internet service fees for
  connection to content providers or connection
  across research networks
• Participate in new global collaborative models
  such as YouTube.com, MySpace or CineGrid
• Direct connection to content and application
  providers
• Student installs transceiver or simple media hub
  at their computer
• Media hub with CWDM for about 200 which includes
  laser, Gbe transceiver etc

How it would work

• A few selected students in university dorms would
  be given UCLP software and access rights to a
  subset of optical/VLAN switches on campus and
  backbone network
• Participating institutions would have to deploy
  RPON or layer 2 ethernet switch which supports
  UCLP at network connection point to lightpath
  networks and transit IP networks
• Could be done at campus or at regional transit
  exchange
• Students would be encouraged to establish their
  own layer 1 peer to peer networks linking their
  servers together as well as those of YouTube and
  CineGrid
• Initially small STM-8 1G lightpath(?) would be
  allocated across partner networks which would be
  partitioned into smaller STM-1 lightpaths for
  student networks
• Rather than building a mesh network the students
  would be encouraged to deploy virtual routing or
  layer 7 routing at various nodes to minimize
  lightpath meshing
• But actual logical network architecture and
  topology would be decided by students

Background material

• it only takes about 10 BitTorrent users bartering
  files on a node (of around 500) to double the
  delays experienced by everybody else.
