Network anomalies such as packet reordering and delay spikes can result in spurious retransmissions and degrade performance of reliable transport protocols such as TCP and SCTP. Past research showed that in certain networks or paths, such anomalies were fairly common. The result was a series of proposals (Eifel, DSACK-based, F-RTO) targeted towards making a(More)
In this paper, we describe the approaches taken in the 4WARD project to address the challenges of the network of the future. Our main hypothesis is that the Future Internet must allow for the fast creation of diverse network designs and paradigms, and must also support their co-existence at run-time. We observe that a pure evolutionary path from the current(More)
One of the primary principles of Software Defined Networking (SDN) is that representing networks as a collection of simple abstractions implemented as an API - rather than as a collection of standardized and proprietary protocols and command line interfaces - will lead to networks that are easier to build and manage. Application of this principle has(More)
Page 1 (12) Abstract—In the current Internet, TCP’s congestion control is performed end-to-end, possibly assisted by simple and limited congestion feedback mechanisms in routers such as Explicit Congestion Notification (ECN) or Random Early Detection (RED). In order to control network traffic more accurately by reducing or even preventing congestion in(More)
