Abstract
This paper reports on the comparison of recovery strategies in MPLS-TE experimental testbeds. We focus on alternative notification mechanisms and compare different end-to-end recovery techniques. A measurements campaign has been performed in two different trials based on commercial routers and PC/Linux boxes. In the former an inbuilt signaling-based mechanism provides remote fault notification to the edge routers while in the latter a prototype of IGP flooding-based mechanism has been implemented. We investigate the impact of the alternative fault notification schemes and present a performance evaluation distinguishing different components of the overall recovery time. We believe that the ideas and experimental insight contained in this work will be helpful to other people involved in standardization and implementation of MPLS-related recovery techniques.
