Middleboxes in private networks have been known to change packets in many ways, making it hard to design protocol extensions that work for the large majority of Internet users. Addressing the need to know what such middleboxes do, we introduce a tool called fling ("flexible ping"). fling can carry out (almost) any kind of protocol dialogue between a server and a client based on a simple...
Most Internet communication uses the Transmission Control Protocol (TCP) at the transport layer. TCP carries out many tasks, including reliability, flow control and congestion control. Congestion control is a mechanism that is concerned with the path between two hosts, but TCP instances operate for separate communicating processes (as identified by port numbers). This means that multiple TCP connections...
RINA, the Recursive InterNetwork Architecture, is a novel “back to basics” type approach to networking. The recursive nature of RINA calls for radically different approaches to how networking is performed. It shows great potential in many aspects, e.g. by simplifying management and providing better security. However, RINA has not been explored for congestion control yet. In this paper, we take first...
