Enhancing the performance of an operational network, at both traffic and resource levels, are major objectives of Internet engineering.
This is accomplished by addressing traffic performance requirements, while utilizing network economically and reliably.
An important objective of Internet traffic engineering is to facilitate reliable network operations [RFC-2702].
This results in a minimization of the network to service outages arising from errors, faults and failures occurring within the infrastructure.
A goal of the service provider, therefore, is to enhance the properties of the network while taking economic considerations into account.
