MPLS implementation for the Linux kernel

There is an increased demand for new functionalities of the network equipment. Smaller companies that develop such functionalities build their products based on the open-source solutions. Linux is currently the most popular open-source operating system and thus the majority of products are based on it. As MPLS is becoming indispensable in the network core, the need for more stable version of MPLS for Linux becomes evident. Thus, this work focuses on the improvement of MPLS implementation for Linux kernel. It presents architecture and performance of this implementation. Its performance is compared to the performance of IP packets forwarding and existing MPLS implementations.
