Abstract	Several packet marking-based mechanisms have been proposed to manage congestion in multistage interconnection networks. One of them, the MVCM mechanism obtains very good results for different network configurations and traffic loads. However, as MVCM applies full virtual output queuing at origin, its memory requirements may jeopardize its scalability. Additionally, the applied packet marking technique introduces certain delay to detect congestion. In this paper, we propose and evaluate the Scalable Early Congestion Management mechanism which eliminates the drawbacks exhibited by MVCM. The new mechanism replaces the full virtual output queuing at origin by either a partial virtual output queuing or a shared buffer, in order to reduce its memory requirements, thus making the mechanism scalable. Also, it applies an improved packet marking technique based on marking packets at output buffers regardless of their marking at input buffers, which simplifies the marking technique, allowing also a sooner detection of the root of a congestion tree.
