Minei I., Lucek J. MPLS-Enabled Applications: emerging developments and new technologies

John Wiley & Sons Ltd, 2005. – 435 p.
Multi-Protocol Label Switching (MPLS) began in the mid-1990s with just two modest design objectives. The first was a better integration of ATM with IP by providing a single IP-based control plane that could span both ATM switches and IP routers. The second objective was to augment the IP control plane with some additional functionality, namely traffic engineering using constraint-based routing that was already present in the ATM control plane.
The aim in writing this book was to describe the latest developments in MPLS. The field is moving so fast that some new applications of MPLS have already been deployed in production networks, yet are not described anywhere in book form.
