Exploiting the IPID Field to Infer Network Path and End-System Characteristics
نویسندگان
چکیده
In both active and passive network Internet measurements, the IP packet has a number of important header fields that have played key roles in past measurement efforts, e.g., IP source/destination address, protocol, TTL, port, and sequence number/acknowledgment. The 16-bit identification field (IPID) has only recently been studied to determine what information it might yield for network measurement and performance characterization purposes. We explore several new uses of the IPID field, including how it can be used to infer: (a) the amount of internal (local) traffic generated by a server; (b) the number of servers in a large-scale, load-balanced server complex and; (c) the difference between one-way delays of two machines to a target computer. We illustrate and validate the use of these techniques through empirical measurement studies.

Because of rapidly rising network traffic, ISP providers are trying to create new network structures and extend more resources to control the growth of demands. It is important to efficiently split the network bandwidth among different sources so that each user has enough bandwidth. Traffic engineering is used to achieve this goal. Performing reliable and efficient network ope...
متن کاملOn Exploiting Long Range Dependency of Network Traffic in Measuring Cross Traffic on an End-to-end Basis
In this paper we present three theoretically grounded methods: prediction, reconstruction and interpolation, for measuring cross traffic on the bottleneck link of an end-toend path. The objective is to infer cross traffic as accurately as possible, while not injecting a significant amount of probe packets into the network. In the prediction-based method, we take advantage of the LRD characteris...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
متن کاملAS Path Inference by Exploiting Known AS Paths
Inferring AS-level end-to-end paths can be a valuable tool for both network operators and researchers. A widely known technique for inferring end-to-end paths is to perform traceroute from sources to destinations. Unfortunately, traceroute requires the access to source machines and is resource consuming. In this paper, we propose two algorithms for AS-level end-to-end path inference. The key id...
متن کاملDesign of an Intelligent Controller for Station Keeping, Attitude Control, and Path Tracking of a Quadrotor Using Recursive Neural Networks
During recent years there has been growing interest in unmanned aerial vehicles (UAVs). Moreover, the necessity to control and navigate these vehicles has attracted much attention from researchers in this field. This is mostly due to the fact that the interactions between turbulent airflows apply complex aerodynamic forces to the system. Since the dynamics of a quadrotor are non-linear and the ...
