Many data center applications have deadline requirements, which pose a requirement of deadline-awareness in network transport. Completing within deadlines is a necessary requirement for flows to be completed. Transport protocols in current data centers try to share the network resources fairly and are deadline-agnostic. Recently several works try to address the problem by making as many flows meet...
The separation between edge and core addresses has been proposed to address the scalability problem of the Internet routing system. One main challenge is to design an efficient mapping mechanism for the two address spaces. The layer structure is attractive because of its scalability and simple index mechanism, while existing layered mapping system lacks a clear structure study and faces serious deployment...
Internet routing system is the fundamental components of Internet. As the Internet growth, Internet routing system is facing the scaling issues of global routing table expanding due to the wide use of multi-homing, traffic engineering, and mobility. Existing proposed solutions need to change host protocol stack or routing architecture, hence, no incentive for practical deployment. In this paper, we...
In this paper, we study how to select a high performance end-to-end path in multi-hop cognitive wireless networks. Due to the time-varying spectrums and undetermined activity of primary users, path selection in cognitive wireless networks is much harder than that of traditional wireless networks. To attack this problem, we propose a novel routing metric, called WHAT (Weighted Hop, spectrum-Awareness,...
Without proper receiving buffer assignment, Concurrent Multipath Transfer (CMT) could result in either not being able to achieve aggregate bandwidth or being a waste of memory resources. This paper analyses buffer requirement for CMT and find that receive buffer requirement is linearly correlated to ratio of round trip time of different path. Based on buffer requirement analysis, this paper proposes...
The current Internet addressing architecture does not verify the source address of a packet received and forwarded. This causes serious security and accounting problems. Based on the drastically increased IPv6 address space, a "source address validation architecture" (SAVA) is proposed in this paper, which can guarantee that every packet received and forwarded holds an authenticated source...
For pt.1 see ibid., p.54-59 (2005). This work spawned an effort in the IETF to develop a generalized method for routing and tunneling different address families across uniform IPv4 or IPv6 backbone networks. Inspired by the CERNET2 effort, the IETF softwires working group has introduced a framework for a solution that offers a generalized, network-based capability for routing and tunneling multiple...
