The module sets up a QoS tunnel over the IP/Ethernet infrastructure over which it will multiplex the different services. The bandwidth of the QoS tunnel used by the module can be set by the operator enabling an optimal use of the network infrastructure, which is important in particular for last mile connections. The available capacity can then be allocated to the respective services multiplexed over the QoS tunnel, such as DVB-ASI at a granularity of 0,5 Mbps. An adapted SMPTE2022/COP Forward Error Correction scheme is implemented to protect the link from errored or dropped packets.
- 6 SFP port for Optical or 10/100/1000 Ethernet
- Bandwidth granularity in steps of 0.5 Mbps
- Full multiservice support for video, audio and data services
- QoS Multicast support
- Advanced clock recovery
- Comprehensive protection options
- Performance management based on ITU-T G.826
The module can be used in any existing Nimbra 600 product and co-exist with other available Nimbra trunk modules and may therefore be used for a seamless migration from SDH/ SONET to a packet based network infrastructure. It provides Forward Error Correction (FEC) to mitigate packet losses and uses advanced clock recovery functionality for preserving the QoS in terms of jitter and wander over the packet network.
The combination of service re-routing capability based on link performance and the ability to transport media services over both IP and optical links makes the Nimbra platform a unique solution for introduction of media services. As the broadcaster requirements for different media feeds may vary a lot depending on resolution, coding and usage, the operators ability to deploy an optimal mix of IP capacity and optical links will be key to differentiating the service offering based on QoS aspects. The Nimbra platform with its new 6 x IP/Ethernet Trunk Module offers just this freedom of choice for selecting the right transport for the right service.
