MPLS has emerged as the new networking layer for Service Providers throughout the world. For many Service Providers and enterprises MPLS is a way of delivering new applications on their IP networks, while consolidating data and voice networks. MPLS has grown to be the new default network layer for Service Providers and is finding its way into Enterprise networks as well. As opposed to the other books from Cisco Press on MPLS, this book will focus on the building blocks of MPLS (forwarding packets, LDP, MPLS and QoS, CEF, etc.) and not on a specific MPLS applications (MPLS VPN or MPLS Traffic Engineering). MPLS Fundamentals will provide readers with a basic understanding of MPLS and its applications. Readers will receive a comprehensive overview of all the aspects of MPLS, including its applications and a perspective on the future of MPLS. Additionally, the reader will be initiated into the world of MPLS and after reading the book, will be able to make a decision about which MPLS application or network design fits his or her needs.
