6 Core Capacity Planning and Traffic Engineering

This chapter addresses core capacity planning and how traffic engineering can be used as a tool to make more efficient use of network capacity.

6.1 Core Network Capacity Planning

Capacity planning of the core network is the process of ensuring that sufficient bandwidth is provisioned such that the committed core network SLA targets of delay jitter, loss, and availability can be met. In the core network where link bandwidths are high and traffic is highly aggregated, the SLA requirements for a traffic class can be translated into bandwidth requirements, and the problem of SLA assurance can effectively be reduced to that of bandwidth provisioning. Hence, the ability to assure SLAs is dependent upon ...
