Recent Developments

• Coachella Valley Fiber Project Extension into
  University of Arizona, Arizona State University
• CSU Campus Access Infrastructure Project

4
Coachella Valley Fiber Project

• 3.4M grant to build diverse fiber ring through
  Coachella Valley (Palm Springs)
• Supported by backbone redesign to resolve Los
  Angeles single point of failure
• The backhoe can be your friend!

Fiber along the tracks
7
Extending Reach

• Extending reach requires placing equipment in
  remote amplification/repeater huts
• Huts are in remote areas, often difficult to find
• Agua Caliente (Gillespie, AZ)

8
Hunting for the hut

CSU Campus Access Infrastructure

• CSU Systemwide Initiative
• Greatly Improve Campus access to Backbone
• Multiple paths from campus to backbone
• Dramatic increases in network bandwidth
• Managed Fiber and/or Managed GigE as available

10
Looking to the Future

• CalREN-DC Upgrades
• CalREN-HPR XD Upgrades
• CalREN Optical Backbone Planning

11
CalREN-DC Upgrades

• CENIC is working on an equipment replacement plan
  to upgrade/update the DC backbone
• Requirements developed by DC-TAC
• Engineering plan under development by CENIC Core
  Engineering staff
• Proposal will be introduced Wed Afternoon

CENIC Peering Success Story

• gt 70 Networks
• gt 130 Peering Sessions

14
Major Peering Milestone!
CENIC Peering exceeds paid transit volume

CalREN-HPR XD Upgrades

• HPR-TAC has been working on network requirements
  document
• Board XD committee providing input as XD
  requirements
• HPR-TAC design sub-group working on drafting
  HPR/XD future design
• Presentation/discussion Thursday, March 16

17
CalREN Optical Backbone

• CalREN Optical Backbone based upon Cisco 15808
  and 15454 DWDM platform
• 15808 End-of-Life announced February 2010
• Defines significant event for completion of
  implementation of new optical backbone
• Re-design of optical backbone to begin after
  development of DC and HPR designs
• Review of recent optical developments to begin
  this summer
• 40Gb lambdas, ROADM, electronic dispersion
  compensation, etc.

18
Operations Status

• Ticket Survey Results
• Inventory Documentation Project
• Failure Analysis, Performance Predictors

19
Ticket Survey Results

• Response time met or exceeded expectations (93)
• Received communications in a timely manner (93)
• Time to resolution exceeded or met expectations
  (91)
• Satisfied or very satisfied with service (93)

20
Ticket Survey Results
21
Ticket Survey Results

• Higher ratings (gt91) correlate closely with
  initial and early communications between NOC
  Engineers and respondents.
• Lower ratings (85-88) correlate with closing
  communications. Communications primarily via
  email scored lower ratings.
• These observations helped us to identify areas
  for improvement
• NOC Engineers will be coached to enhance email
  communications, particularly in the areas of
  thoroughness and articulation.
• To address perceptions of impatience and
  follow-through, our procedures confirm through a
  ticket update prior to the ticket resolve
  notice that the support requester does not have
  any outstanding questions or concerns, and that
  he or she agrees the problem is resolved.

22
Inventory Project Status

• Inventory data stored in MySQL database
• Assets polled nightly
• Email to NOC if polled differs from stored
• Display Asset Info
• This is an ongoing focus for CENIC

23
Failure Analysis

• FIT (Failures in Time)
• Failures in 1,000,000,000 hours
• Failures and replacements tracked in inventory
• Mean Time to Repair is critical factor in network
  availability

24
9s of Reliability

• Chart plots reliability against FIT (log scale)
  and MTTR
• Shows what is necessary to achieve 3-9s up to
  6-9s of network availability

25
Unavailability of Systems

• Parallel
• Up U1 U2 Un
• Serial
• Us U1 U2 Un

26
Flow of an Optical Path
27
Fiber Availability (per 1,000 miles)

• Industry Standard
• 1.5 cuts per year
• Vendor A
• Goal is 0.5 cuts per year
• Actual (2003) 0.69 cuts per year
• MTTR goal of 6 hours
• FIT 78,623
• Unavailability 0.0471738 (99.95 availability)

28
Applying FIT MTTR

• Must track operational hours BY COMPONENT
  (in-service to out-of-service) as components
  added/replaced
• Each failure tracked BY COMPONENT
• Down time tracked BY COMPONENT, identify if
  traffic affecting or not
• MTTR could actually vary by component
