lambda service path

IP service path

day to day lightpath use
Day-to-day lightpath use
  • Part of lambda capacity statically configured for IP production traffic
    • Router-to-router SONET circuits between Amsterdam and Chicago for SURFnet and others (e.g. NSF link)
    • Link & interface state monitored by SURFnet NOC
  • Part of lambda capacity for lightpath research community
    • Changed on weekly/monthly basis upon request
    • Has a ‘test’ status; is hardly monitored by NOC
application for a lightpath
Application for a lightpath
  • Researchers can apply for a lightpath by an e-mail to netmaster-optical@surfnet.nl
  • Information in the application should include:
    • Test purpose
    • End points A and Z [CERN, StarLight, Stockholm]
    • Interface type [1GbE: SX or LX, 10GbE WAN PHY]
    • Number of lightpaths needed
    • Lightpath capacity in multiples of SONET STS-6 (311Mb/s):[STS-6 / STS-12 / STS-24 / STS-48 / STS-192] *
      • Full GbE capacity: STS-24 *
    • VLAN ID (if applicable)
    • Start date, end date
    • Contact details (e-mail, phone)

* Bandwidth granularity depends on transport equipment, e.g. Cisco ONS15454

day to day operations 1
Day-to-day operations (1)
  • SURFnet NOC manages production network plus NetherLight
    • Part of NetherLight has production status
    • NetherLight test circuits get lower priority than SURFnet5 IP network
  • Some learning curve to get NOC engineers familiar with transport (SONET) troubleshooting
    • ONS15454 network operations: craft terminals only
  • DWDM link to Dwingeloo (ASTRON): very stable, no pro-active management of optical system yet
    • DWDM (ONS15252) craft terminal is not very user-friendly
day to day operations 2
Day-to-day operations (2)
  • International lambda network monitoring
    • SNMP monitoring by NOC for SONET alarms and port errors
    • BER level monitoring on ONS15454 SONET ports
      • BER parameter is part of SLA with carriers
    • GbE ports: errors mostly attributable to LAN troubles
    • No IP traffic monitoring possible on SONET ports
      • ONS15454 cannot look inside SONET circuits, only provide overall quality information (BER, errored-seconds etc)
  • No trouble with clocking observed yet
    • SONET network should have one master clock
    • ONS15454 internal Stratum III clock is sufficient, no external clock needed
day to day operations 3
Day-to-day operations (3)
  • Layer0: optical cross connect
    • Calient Photonic Cross Connect, automated patch panel
    • Research status only, managed by University of Amsterdam
    • Topology discovery difficult
  • Layer1: SONET layer
    • Very flexible GbE path setups on +- biweekly basis
    • 10G end-to-end also possible, for couple of months at a time
    • Multi-domain setup works very well by building half-circuits
    • ONS15454 networks from Canet and SURFnet pre-wired at StarLight
what did we learn need to work on
What did we learn / need to work on
  • Point to point lambdas are a powerful service
    • High-performance research groups are pulling at us after getting a taste of 10GE all-the-way…
  • Straightforward to build a hybrid network architecture on top of optical:
    • Some lambdas to interconnect your IP prod. routers
    • Some lambdas for new high speed few-to-few usage
  • Current optical-electrical-optical equipment can allocate sub-lambdas to individual applications
    • Ethernet-over-SONET based, this will get more advanced soon (we need to learn what LCAS can do here)
  • Management is still cumbersome, learning curve for all of us
    • How to make this dynamic? Or self-provisionable…?
