“…Častým problémom je napríklad určenie tých bodov siete, v ktorých môžu byť merania uskutočnené [4]. Ďalší problém predstavuje pojem času, ktorý má silný vplyv na presnosť výsledkov meraní [4,25]. Primeraná časť týchto problémov bola za posledné desaťročie úspešne vyriešená.…”

“…Agregácia je zabezpečená vytvorením záznamov o tokoch, ktoré pozostávajú z informácií o kľúčových charakteristikách sieťovej prevádzky. Tieto záznamy sú pravidelne exportované pre rôzne účely, ako monitorovanie prevádzkových charakteristík, účtovanie alebo správa sietí [3,25,26]. Smerovače od spoločnosti Cisco sú schopné, prostredníctvom vlastného protokolu Netflow [3], vytvárania takýchto záznamov o tokoch, ktoré obsahujú dôležité štatistiky o prevádzke sietí.…”

“…In [20], Wolf et al propose Distributed Online Measurement Environment (DOME), a distributed system of passive measurement nodes equipped with Intel IXP2400 network processors. Their work includes header anonymization schemes with performance of flows up to 500 Mbit/s of minimum-sized packets (64 bytes), as compared with full line-rate capability of both Endace DAG cards and our solution.…”

Abstract-Network measurement both as diagnostic and within measurement-based techniques of traffic engineering and management, alongside network measurement for security has maintained the needs of researchers and network operators for the ongoing development of measurement tools for traffic monitoring/characterisation and to support Intrusion Detection Systems (IDSs). Many such tools capitalise on the pricing of commodity hardware by operating on general purpose architectures. Many are based on the well known libpcap API, a de facto standard in this area. Despite the many improvements that have been applied to packet capturing, packet-monitoring implementations still suffer from either: performance flaws on commodity hardware due mainly to unresolvable hardware bottlenecks, or costly and inflexible niche systems. To address such issues, the paper proposes a system architecture based on the cooperation of NetFPGA and a general purpose host PC. The NetFPGA is an open networking platform accelerator that enables rapid development of hardware-accelerated packet processing applications. The objective is to combine the high performance of a hardwareoriented solution with the flexibility of general purpose PCs.

“…In many network measurement scenarios, data is collected in a distributed fashion to obtain a broader view of the state of the network than can be achieved with a single measurement point [25]- [27]. Utilizing multiple measurement systems raises a number of challenges that are related to the issue of sampling: (1) Data collected from different measurement nodes needs to be merged into a single coherent "view;" (2) Synchronization between system needs to be considered to ensure the results are consistent.…”

Abstract-The increasing complexity of the Internet demands continued improvements to measurement techniques and data analysis methods to aid our understanding of network operation. The availability of accurate measurement data is necessary in many areas ranging from attack detection, novel pricing schemes, buffer dimensioning and switch design to general network management. In this paper, we develop a theory for accurate and unbiased Internet traffic measurement using the tools of Poisson random sampling. We show how this approach helps in storing, managing, and aggregating data from different sources with independent clocks and sampling rates. We present results that show that stochastic sampling maintains important information about network measurements that would be lost when using conventional uniform sampling.
