Class of Service COS Class of Service is a mechanism for designating different priorities to network streams. Routers will maintain separate queues for different priority streams and based on the policies installed in the router, streams will be routed according to their priority if the router is faced with congestion on a link. N3 has a range of Classes of Service defined in its QoS Policy, in order that N3 Customer who use Catalogue Service that are QoS enabled can classify their applications to an appropriate Class of Service to support the most efficiently utilisation of their available network bandwidth.
Community of Interest Network COIN COINS are established via an intelligent network design for a community of sites with similar business needs. They can cover both Local and National Programme needs, although are usually more oriented to meet defined local needs. They can be purely local initiatives, including full local funding or they can deliver combined needs, both local and National Programme, in which case the National Programme will contribute to the costs, whilst ensuring the design will satisfy the National Programme Service Levels for at least the National Programme part of the design.
