Trace routes may show University Enterprise Routers have hops with High Latency/Loss
Staff from the Office of the Vice Provost for IT, Telecommunications and Network Services have been actively working on a problem with the University Enterprise Network. Periodically Line cards on 100G Interconnects have a high cpu utilization.
Staff at this point have done extensive testing and have determined that traffic transiting though the router links does not get affected by this issue and there should be no cause for concern or performance degradation.
IT professionals preforming trace-routes though the University Park UEN may see that the tool reports high latency and in some cases periodic loss on “Hops” that are UEN Distribution router themselves (Examples Computer3, Telecom8, Willard3, etc)
The exact cause is not know at this time, this condition has been suspected to have been happening for 6 or more months since the UEN hardware was moved to a new vendor. The current issue is being worked actively by OVPIT in ServiceNOW problem record PRB0040278. OVPIT is working with the vendor to see what can be done to remedy the condition.
IT Professionals that need help interpreting trace-route results or UEN performance issues are encouraged to engage the Operations Center for further assistance.
