“…Those solutions can be divided into software-based such as Driverdump [12] and Interrupt Coalescence (IC) technique [13], kernel patching [14] and hardware-based solutions such as Network Processor (NP) [8], [15], [16], and special purpose DAG card [10]. Some solutions try to build special purpose facilities, but those solutions are cost inefficient.…”

Abstract-This paper presents a reliable and complete traffic collection facility as a first and crucial step toward accurate traffic analysis for network characterization and user behavior. The key contribution is to produce an accurate, reliable and high fidelity traffic traces as the valuable source of information in the passive traffic analysis approach. In order to guarantee the traces reliability, we first detect the bottlenecks of the collection facility, and then propose different monitoring probes starting from the ethernet network interface and ending at the packet trace. The proposed facility can run without stop for long time instead of one-shot periods, therefore, it can be used to draw a complete picture of network traffic that fully characterize the network and user behavior. The laboratory experiments conclude that the system is highly reliable, stable and produces reliable traces attached with different statistics reports that come from the installed monitoring probes.

“…Commercial examples of network processors are the Intel IXP2350 [12], the EZchip NP-3 [13], and the LSI APP [14]. Network processors have been used in a number of scenarios to provide advanced packet processing functions ranging from simple forwarding [15] to complex functions like network measurement [16].…”

“…The congestion control mechanism of the sender will slow down the sending rate until buffer space becomes available. Packets are only forwarded when the downstream connection does not have too much outstanding data (lines [15][16][17][18]. Lines 20-26: If an ACK is received, then buffer space in the complementary flow (flow in the opposite direction, denoted by f ) can be released.…”

Active probe-based measurements are the foundation for understanding important network path properties such as SLA compliance and available bandwidth. Well-known challenges in active probe-based measurement include the logistics of deploying and managing host-based measurement infrastructures, the load that probe packets place on network resources, the inaccuracy of resultant measurements, and the relatively limited set of features that can be measured. In this paper, we argue that these challenges can be addressed through programmable, router-based support for active measurement. While commercial routers today have some basic capabilities for emitting probe packets, these mechanisms are minimal and do not allow the necessary flexibility in the kinds of probing that can be done. We describe a set of functional primitives that enable a wide range of router-based active measurements and would improve and simplify the ability to assess and understand network structure and dynamic network state. We discuss the associated resource requirements and implications of our approach related to configuration, security and privacy. Finally, we support and illustrate the powerful potential of our approach through a series of measurement scenarios and describe our ongoing efforts toward a Click-based implementation of our framework.
