Large-scale TCP models using optimistic parallel simulation
Garrett Yaun, Christopher D. Carothers, Shivkumar Kalyanaraman · 2003
Internet data traffic is doubling each year, yet bandwidth does not appear to be growing as fast as expected and thus short falls in available bandwidth, particularly at the "last mile" may result. To address these bandwidth allocation and congestion problems, researchers are proposing new overlay networks that provide a high quality of service and a near lossless guarantee. However, the central question raised by these new services is what impact will they have in the large? To address these and other network engineering research questions, highperformance simulation tools are required. However, to date, optimistic techniques have been viewed as operating outside of the performance envelope for Internet protocols, such as TCP, OSPF and BGP. In this
