Engineering a multiservice IP backbone to support tight SLAs

This paper describes technologies that enable IP service providers to offer tighter service level agreements for IP performance, in order to create competitive advantage and better serve their customers. The SLA parameters that need to be tightened are defined and then the technologies that should be considered are described, together with the decision criteria on where each technology should be used. This paper is based upon current best practise and includes results from both lab testing and deployment experience. The specific technologies discussed are differentiated services, fast IGP convergence, and traffic engineering. Consideration is given to how these technologies should be deployed and operated.
