Overview: This paper presents a framework for providing soft bandwidth-guarantees over a best-effort network. Such a guarantee is provided through the use of an elastic TCP-based tunnel running between ITMs. The target bandwidth could be dynamically adjusted to meet the needs of applications. The elasticity of the established tunnel is achieved by adjusting the number of open TCP connections between ITMs to a quiescent number, large enough to push back against crosstraffic.
