The IP/Ethernet Trunk Module is typically used to interface a service aware media network with the underlying IP core network. By creating a media service overlay using MSRs from Net Insight, the network becomes aware of each individual media service. Each service can be provisioned, monitored and protected, not only as a member of a class of service, but individually, on-demand and on an end-to-end basis.
- Lossless routing. From ingress port to egress port, a Nimbra MSR never loses a single packet. Lossless routing is possible thanks to dedicated QoS allocation per service, together with Net Insight’s unique time synchronization.
- QoS enhanced links. At each hop, the Nimbra MSR performs specific tasks to improve the QoS of the underlying IP network. This functionality consists of Forward Error Correction to reduce packet loss, traffic shaping to facilitate resource allocation and resynchronization to reduce jitter and wander.
- Service-centric network management. In a Nimbra MSR network, each service can be provisioned, monitored and protected individually, on demand and on an end-to-end basis.
- 3 SFP ports for Optical or 10/100/1000 Ethernet
- Bandwidth granularity in steps of 0.5 Mbps
- Full multiservice support for video, audio and data services
- Advanced clock recovery. Automatic clock recovery circuitry that adapts to packet network jitter/wander levels, with automatic fallback to local or external reference.
- Performance management based on ITU-T G.826
The performance monitoring is done on actual data path traffic and does not require the extra overhead or equipment of external probing systems. Performance monitoring can be consolidated over time and/or topology to produce reports for SLA follow-up.
