تبديل الوسوم المتعدد البروتوكولات (MPLS)

As the Internet growing at a high pace, the technology has had to adapt constantly to new demands for increased bandwidth. In addition to the traditional services currently provided, new services have been developed and deployed, which have strained the resource of the existing Internet infrastructure. Moreover, with the implementation of Internet protocol version 6 (IPv6), carriers and service providers struggle to find efficient and speedy methods to forward packets and provide guaranty for quality of service (QoS), class of service (CoS), traffic engineering, and support virtual private network's (VPN's). MPLS, which at the beginning was a way to enhance the speed of router's forwarding, emerged as a new standard technology to provide the above-mentioned services. This study provides a detailed analysis of the existing technology behind MPLS and its components, mechanism and applications.
