Information Centric Networking (ICN) is seen as a promising solution to re-conciliate the Internet usage with its core architecture. However, to be considered as a realistic alternative to IP, ICN must evolve from a pure academic proposition deployed in test environments to an operational solution in which security is assessed from the protocol design to its running implementation. Among ICN solutions,...
Service function chaining provides a new service deployment model that delivers the traffic along the predefined logical paths of service functions with no regard of network topologies or transport mechanisms. The traffic path of service functions needs to be recovered at failure of the service functions but it may incur a signaling delay among control-plane and data-plane components. In order to...
Queue management is an important part to provide better service of buffer at the Internet router. Active Queue Management (AQM) technique is used to improve the network performance like link utilization, delay, fairness and packet loss rate. In this paper we explore the impact of buffer size and round trip time (RTT) on AQM router where TCP Reno is used as transport protocol in single bottleneck dumbbell...
The Low Extra Delay Background Transport (LEDBAT) protocol is a recently standardized protocol that aims to offer a scavenger service (i.e. the goal is to exploit the remaining and unused capacity of a link). LEDBAT is a delay-based protocol mainly defined by two parameters: a target queuing delay and a gain. The RFC 6817 provides guidelines to configure both parameters that strongly impact on the...
The resource of DTN (Delay Tolerant Network) is constrained and its links are unstable, so the states of network can't be fed back in time to the source node of data. The rate control mechanism and window mechanism of congestion control can't solve the congestion problem of DTN. The paper has proposed A DTN Congestion Control Mechanism Based on Distributed Storage (DCM). When the congestion of a DTN...
Measurement studies of the Internet topology have revealed that the degree distribution exhibits a power-law attribute. That is, the probability P(k) that a node has k outgoing links follows P(k) ~ k-gamma. However, it is known that the power-law degree distribution alone does not determine traffic-level behaviors in Internet topologies. In this paper, we investigate packet-level delay behavior of...
