“…Although a considerable amount of flow characteristics were observed and correlated, the authors did not use various definitions for an IP flow, considering only the traditional 5-tuple flow definition 2 . In a previous work of ours [22], we concluded that there is no substantial variation in the definition of a flow in most of the investigated related works. As a result of that, we decided to perform our analysis by considering various definitions for a flow [22].…”

Abstract-The advance on data transmission in optical networks has allowed data forwarding decisions to be taken at multiple levels in the protocol stack (e.g., at network and optical levels). With such capability, big IP flows can be moved from the network level and switched completely at the optical level over lambda-connections, where they get better Quality of Service (QoS). Meanwhile, the regular IP routing level is offloaded and can serve smaller flows better. With the continuous growing of traffic on the Internet, the selection of big IP flows can become difficult to be done by using current management approaches (conventional management and Generalized Multiprotocol Label Switching (GMPLS) signaling). The University of Twente (UT) is researching the use of self-management as an alternative to overcome this issue. In order to properly identify IP flows eligible to be moved to the optical level, the characteristics of these flows must be known, though. In this context, this paper analyses some of the characteristics of IP flows eligible to the optical level by observing their size, duration, throughput, and recurrence. In this analysis, we observe those characteristics while using various definitions for an IP flow as well as using different time intervals. The main contribution of this paper is to show the behavior of IP flows eligible for lambda-connections. Not in the least, we also show how this knowledge can be used in our self-management of optical networks approach.

“…There are many definitions of flow available in the literature [16,17] but we follow the IP Flow Information Export (IPFIX) working group of the IETF [18]. As per IPFIX, a flow can be defined as a set of IP packets passing through a monitoring point in a network during a particular time interval.…”

“…For example, a DNS request is usually sent using only one packet, so the resulting flow record can be exported almost immediately. However, some applications, e.g., video streaming, generate large number of packets over a period of time [13], therefore the inactive timeout should be longer. By analyzing the behavior of major application protocols we can make the flow cache management more effective.…”

Abstract. Deep packet inspection (DPI) and IP flow monitoring are frequently used network monitoring approaches. Although the DPI provides application visibility, detailed examination of every packet is computationally intensive. The IP flow monitoring achieves high performance by processing only packet headers, but provides less details about the traffic itself. Application-aware flow monitoring is proposed as an attempt to combine DPI accuracy and IP flow monitoring performance. However, the impacts, benefits and disadvantages of application flow monitoring have not been studied in detail yet. The work proposed in this paper attempts to rectify this lack of research. We also propose a next generation flow measurement for application monitoring. The flows will represent events within the application protocol, e.g., web page download, instead of packet stream. Finally, we will investigate the performance of different approaches to application classification and application parsing with a computational complexity in mind.
