GENI Internet2 Switch URN Renaming

Internet2 plans an effort to migrate from SDN to MPLS in the AL2S backbone. The implementation of MPLS is to be verified by the ability to exchange GENI experiment traffic both via stitching or OpenFlow Over stitching after the upgrade has taken place. (Validation covered in sections x.x.)

This effort also includes a task to rename AL2S Switches from sdn-sw to rtsw. The renaming effort impacts: 1) GENI Aggregates, 2) Stitching Computation Services and 3) GENI Monitoring 4) Numerous wiki pages capturing network connectivity details. Thus is the bulk of the effort covered in all sections below.

Impacted Sites

The renaming effort impacts 26 AL2S switches whose URN is to be changed. Only 9 AL2S switches that are to be renamed have have stitching sites and require updates to GENI Aggregates, GENI Stitching Computation Service and GENI Monitoring. The AL2S switches with GENI Stitching sites connected are:

Old URN New URN
sdn-sw.alba.net.internet2.edu rtsw.alba.net.internet2.edu
sdn-sw.ashb.net.internet2.edu rtsw.ashb.net.internet2.edu
sdn-sw.bato.net.internet2.edu rtsw.bato.net.internet2.edu
sdn-sw.houh.net.internet2.edu rtsw.houh.net.internet2.edu
sdn-sw.jack.net.internet2.edu rtsw.jack.net.internet2.edu
sdn-sw.loui.net.internet2.edu rtsw.loui.net.internet2.edu
sdn-sw.phil.net.internet2.edu rtsw.phil.net.internet2.edu
sdn-sw.pitt.net.internet2.edu rtsw.pitt.net.internet2.edu
sdn-sw.star.net.internet2.edu rtsw.star.net.internet2.edu

The 9 AL2S switches above have 23 GENI aggregates whose advertisement is to be reconfigured (1 AL2S +22 GENI Sites) to pick up the name change. Following are the details for the AL2S switches that will be reconfigured and tested along with the number of ports configured for switching and the switching sites associated with those ports.

  1. Switch sdn-sw.star.net.internet2.edu has 4 stitching ports, some with multiple sites:
    • et-1/0/0.0 -> uchicago-ig, wisconsin-ig, wisc-clab[1], umich-ig
    • et-7/0/0.0 -> northwestern-ig
    • et-8/0/0.0 -> savi
    • et-9/0/0.0 -> illinois-ig
  1. Switch sdn-sw.pitt.net.internet2.edu has 1 stitching port:
    • et-4/0/0.0 -> psc-eg[1]
  1. Switch sdn-sw.phil.net.internet2.edu has 1 stitching port:
    • et-3/0/0.0 -> rutgers-ig
  1. Switch sdn-sw.loui.net.internet2.edu has 1 stitching port with multiple sites:
    • et-3/0/0.0 -> uky-pg, uky-ig, ukypks2-ig, ukymcv-ig
  1. Switch sdn-sw.jack.net.internet2.edu has 1 stitching port with multiple sites:

  1. Switch sdn-sw.alba.net.internet2.edu has 1 stitching port:
    • xe-5/2/2.0 -> uvm-ig
  1. Switch sdn-sw.ashb.net.internet2.edu has 1 stitching port:
    • et-3/0/0.0 -> vt-ig
  1. Switch sdn-sw.bato.net.internet2.edu has 1 stitching port:
    • et-8/0/0.0 -> ullafayette-ig

[1] Test SCS only. All other sites apply to both Test and Production SCS.

URN Renaming Procedure

1. Generate Ticket and check for conflicts with upcoming events

2. Review Affected Stitching Endpoint
