Examination of Free Capacity Based Load Sharing

Sophisticated traffic engineering (TE) methods are currently under development. The price for broad TE functionality is high, especially in complexity and scalability. Moreover, there are several specialised networks where simpler TE mechanisms are required because of computational or scalability limitations. Such a simpler TE solution is load sharing. Currently, the performance of load sharing is far less exploited than its real potential. This is due to the fact that thus far no sophisticated load sharing architectures have been defined and that the instability issues of dynamic load sharing have not fully been examined and solved. With our paper we aim to extend the understanding of instability issues of dynamic load sharing solutions.
