Bandwidth Profile Algorithm
Bandwidth profile is the enabler of service assurance
Green frames must be delivered per the performance objectives in the SLA
Yellow frames may be delivered but without performance assurance
Decoupled verification of the bandwidth profile rates parameters [CIR-EIR] and burst parameters [CBS-EBS] is imperative
Troubleshooting and automated diagnostics using constant, bursty and a mix of constant and bursty test traffic
Best Effort Parameters
Reporting the exact measured values instead of a simple Pass or Fail [RFC 2544-Y.1564]

Control Protocols handling and verification is a very extensive process and is susceptible to human error
Layer 2 Control Protocols
Each CE 2.0 service EPL, EVPL, EP-LAN, EVP-LAN, EP-Tree, EVP-Tree has its specific requirements for handling L2CPs
35 stateful protocols per service
Service OAM Fault Management
Each CE 2.0 service must be transparent to the Continuity Check, Loopback and Linktrace protocols at the subscriber and test MEF levels
5 stateful protocols at 2 MEG levels

A SERVICE PROVIDER PERSPECTIVE
WITH INTEGRA TELECOM
Before SAMTEST, at the time of turn-up if a failure happened (about 93% of the time) the amount of time spent troubleshooting using a scaled back version of RFC2544 was enormous
As we transition to using the fully automated SAMTEST CE 2.0 test suites, testing and troubleshooting time has been reduced by almost 75%
SAMTEST assisted troubleshooting and automated diagnostics features definitely bring us faster time to revenue
And, the test reports aligned with CE 2.0 greatly simplifies the discussion with our interconnection partners
Typically turning-up 30 E-Access services per month
About 2 of them PASS on the first test iteration and the rest of them FAIL.

BEYOND PERFORMANCE
MONITORING
The main difference between plain old Ethernet services and ‘Carrier Ethernet’ Services is the Quality of Service
But… is performance monitoring sufficient to assure quality of service ?
No…
With all the new high definition and real- time applications offered on Carrier Ethernet networks, its important for service providers to:
Be alerted when performance thresholds are about to be exceeded
Receive auto-diagnostics allowing them to take action and avoid SLA violations

Equipment vendor independent
Real time monitoring of all performance metrics
FD, MFD, IFDV, FDR and FLR
Standards based
Frame sizes, rates, intervals
Alarm generation when SLA thresholds are about to be violated
Auto-diagnostic tests for quick fault isolation and correlation
Multi-layer portals
