Ethernet Demarcation Solution
Introduction
Mingoa's semiconductor IP provides high performance hardware ideally suited for deployment in low
cost NIDs. It polices the traffic into the network and provides OAM and SLA
monitoring of traffic across the network. It provides demarcation between
customers' and carrier networks, and at hand off points between carrier networks.
It polices and monitors the network without degrading the background data flow,
and provides high degree of visibility into the operation and performance of the network.
This cost effective solution polices traffic into the network via an integrated MEF10
based QOS processor. In addition it monitors Ethernet performance against agreed
Service Level Agreements (SLAs) to five-nines degree of accuracy. It measures Frame Loss,
Frame Delay and Frame Delay Variation using ITU Y.1731 standardised messaging. It
detects and isolates faults using 802.1ag CCM and Loopback messaging.

Benefits of Hardware versus Software OAM
Traffic policing using dedicated hardware provides a low cost and accurate solution.
Performance Monitoring using hardware time-stamping and in-line packet counters
gives accurate measurements of Frame Loss, Frame Delay and
Frame Delay Variation. This achieves five-nines level of accuracy that is not easily
guaranteed with software based solutions.
Hardware based OAM supports the detection of faults on multiple services (EVC) in
11.5ms using 3.3ms messaging rates. This enables switchover to backup services
within the 50ms standard set by SONET. This performance is beyond the capability
of most cost effective software solutions.
