Abstract

Ethernet networks are evolving from the enterprise to the carrier thus facing new demands and requirements. Therefore, a set of new control approaches are being defined for Ethernet. Amongst these, IEEE 802.1aq Shortest Path Bridging (SPB) aims to assure the transmission of unicast and multicast frames on the shortest path in a bridged network. Three protocols have been proposed for the control of SPB. This paper provides an extensive analysis of these proposals based on simulations focusing on protocol convergence time, which is a key attribute of carrier grade networks. The simulation model was created based on recent measurements. Furthermore, the analysis presented in the paper provides reference for further development of Ethernet control protocols.
