On the Fair Coexistence of Loss- and Delay-Based TCP

Abstract

Abstract-Delay-based TCP variants continue to attract a large amount of attention in the networking community. Potentially, they offer the possibility to efficiently use network resources while at the same time achieving low queueing delay and virtually zero packet loss. One major impediment to the deployment of delay-based TCP variants is their inability to coexist fairly with standard loss-based TCP. In this paper we propose a simple strategy to make the fair coexistence possible and to ensure that delay-based flows will revert back to the delay-based operation when loss-based flows are no longer present. Analytical and ns-2 simulation results are presented to validate the proposed algorithm.

Experimental investigation of the google congestion control for real-time flows

“…The use of a delay-based approach, instead of the classic loss-based technique employed by the TCP, to transport delay-sensitive traffic is a long debated issue [1]. In fact, it is well-known that the probing phase employed by loss-based algorithms tends to fill the bottleneck queue and, as a consequence, flows can be affected by delays that are unacceptable for real-time communication [5].…”

Cooperative Regulation and Trading of Emissions Using Plug-in Hybrid Vehicles

“…This latter feature makes algorithms from this community attractive in a transportation context. Relevant ideas in this direction include the Kelly framework [20], RED [19,27], AIMD congestion control [18], to name but a few. In the next section we shall illustrate how some of these ideas, together with new vehicle types, can be used to great effect to manage aggregate vehicle emissions.…”

“…See for example [27], where RED is emulated in a distributed fashion. We will not repeat these stability discussions here.…”

Less-than-Best-Effort Service: A Survey of End-to-End Approaches

“…Some of these proposals, like Compound TCP [21], TCP Illinois [22] and RACC [23], are hybrid loss-and delay-based mechanisms, whereas others (e.g., FAST TCP [24], NewVegas [25], or CODE TCP [26]) are variants of Vegas based primarily on delays. 4 Though not specific to Vegas, there are also proposals, such as [27], [28], aiming at improving the coexistence of loss-based and delay-based congestion-controlled flows.…”
