document number revision Seamless integration of data services over unused capacity SCU - SPARE CAPACITY UTILIZATION SCU - Spare Capacity Utilization - adds the capability of utilizing all left-over capacity after allocation of premium services, to be used for elastic data services, thus combining guaranteed service for premium services with full utilization of the network links. The Nimbra MSR provides a guaranteed QoS for premium services such as video and audio in order for broadcasters and media network operators to provide the best possible service with simple SLAs for their customers. There is however also a need to use the spare capacity that is left-over when the premium services have allocated their capaci- ties, for elastic services such as LAN traffic, background file transfers etc, in order to have best return on the investment on the infrastucture cost. SCU solves this by enabling all un-used capacity on a network link for Ethernet traffic without impacting the premium services in any way. By using SCU it is thus possible to combine the guaranteed properties for premium services with 100% utilization of the network links. Besides using the functionality to fill the network links with elastic Ethernet traffic when not using the links for premium services, it can also be used to activate redundant capacity that is normally not used. SCU combines guaranteed QoS properties for premium services with 100% utilization of the network links. TECHNICAL SPECIFICATIONS Feature license activated functionality in NimOS Maintenance: Remote software download Supported hardware:Nimbra 390/380/320/310 (IP & SDH) Nimbra 600 (IP & SDH) (Nimbra 600 requires Ethernet Access plug-in module installed in the node) Function: Pre-emption of one ETS channel (the “SCU-ETS channel”) over one trunk link hop by all other services. Pre-emption means that the SCU-ETS channel adapts its capacity to allocate all free bandwidth on the trunk link at all times. By connecting several SCU-ETS channels using Forwarding Functions, a layer 2 Ethernet network is formed. This layer 2 network support CoS and VLAN separation through the Forwarding Functions and have variable capacity links. Net Insight AB • Phone +46 (0)8 685 04 00 • Configuration: Committed and Excessive capacity limits for the SCU-ETS channel. Usage conditions: One unicast SCU-ETS can be enabled per trunk link. The SCU-ETS channel must terminate in a Forwarding Function on each side of the trunk link. Capacity can not be pre-empted over the backplane of an MSR, only on the trunk links, which may limit the usable capacity in some configurations. Ordering Information: NPM0047-3SCF Spare Capacity Utilization Feature license, Nimbra 300 NPM0047-6SCF Spare Capacity Utilization Feature license, Nimbra 600 One license is needed per SCU-ETS terminating node, irrespective of the number of SCU-ETS channels that terminate in that node.
