Multi Protocol Label Switching With Quality of Service in High Speed Computer Network
Multi protocol label switching is a method that directs data from one system node to the next based on short path labels rather than long network addresses in high-performance telecommunications association. It offers high scalability, end-to-end IP services having simple configuration and management for customers and service providers. It forwards packets in any system protocol, which are the building blocks of data transmitted over the Internet. Each packet has a header. In a non-ATM background, the header contains a 20-bit label, a 3-bit Class of Service and 1-bit label stack.
