With the widespread popularity and rapid development of Internet, the network is becoming more complex. Analysis of network node behavior can be crucial for network management and service provisioning. In this paper, we conduct the detailed measurement analysis of the network node (NN) traffic characteristics based on a large-scale data set collected from an enterprise network traffic monitoring device,...
The router buffer sizing problem is a vital problem to the performance of the Internet. The traditional rule-of-thumb is that the router buffer size should be equal to the bandwidth-delay product (BDP) of a link. Recent studies show that the router buffer size can be significantly smaller than the BDP without causing negative impact on the TCP performance in the Internet. But a fundamental assumption...
The Internet has recently been evolving from homogeneous congestion control to heterogeneous congestion control. Five years ago, Internet traffic was mainly controlled by the standard TCP AIMD algorithm, whereas Internet traffic is now controlled by many different TCP congestion control algorithms, such as AIMD, CUBIC, CTCP, and FAST. However, there is very little work on the performance and stability...
Peer-to-peer (P2P) technology greatly scales up traditional Internet streaming service. However, the philosophy that peers help one another distribute video content produces a large amount of cross-ISP P2P traffic. Newly proposed ISP-friendly P2P mechanisms reduce the cross-ISP P2P traffic by using locality-based peer selection methods with which peers tend to connect to other peers in the same ISP...
With the rapid progresses in the interconnection of national power systems in China, its scale grows fast, its dynamics becomes more and more complex, and the faults of the power grid could significantly damage the national economy. In event of electrical faults, some switches may be opened or closed to modify the configuration of the power systems and avoid the loss of synchronization among multiple...
This paper presents a mechanism to manage a dynamic group in an automatic way for sending Group IM (instant message) based on presence service in IMS system. Presence technology is gaining significant interest nowadays. It can show the user's presence information in real time. Presence based services are driving new business opportunities and changing every aspect of our daily life, especially in...
In IETF, mobile IPv6 signaling and data must be protected by IP security association, while IKEv2 is recommended to make dynamical IPSec security association maintenance. But when mobile node bootstrapped in foreign net work or handover to a new network, IKEv2 cannot get information about MIPv6 to negotiate right IP security associations, which will incur bootstrap failure and long handover delay...
