As corporations seek to reduce costs, improve efficiencies, gain market share, and profit, they increasingly are looking to their own information technology systems as a means to these ends. Traffic engineering allows engineers to maximize network resources. It resolves the issue of having large amount of traffic on certain portions of the network while other portions go under-utilized. Traffic Engineering with MPLS provides readers with information on how to use MPLS traffic engineering and associated features to optimize network bandwidth. The book covers forwarding fundamentals, traffic engineering theory, protocol descriptions, deployment guidelines, configuration, show commands, and debugs. It is a one-stop reference for understanding MPLS traffic engineering and implementing it on the network. A comprehensive case study shows a complete MPLS traffic engineering deployment.
Eric Osborne, CCIE(r) #4122, has been doing Internet engineering of one sort or another since 1995. He joined Cisco in 1998 to work in the Cisco Technical Assistance Center (TAC), moved from there to the ISP Expert team and then to the MPLS Deployment team. He has been involved in MPLS since the Cisco IOS(r) Software Release 11.1CT days.
Ajay Simha, CCIE #2970, joined the Cisco TAC in 1996. He then went on to support tier 1 and 2 ISPs as part of Cisco's ISP Expert team. Ajay has been working as an MPLS deployment engineer since October 1999, and he has first-hand experience in troubleshooting, designing, and deploying MPLS.
