A Statistical Analysis of Network Parameters for the Self-management of Lambda-Connections

Abstract: Abstract. Network monitoring plays an important role in network management. Through the analysis of network parameters (e.g., flow throughput), managers can observe network behavior and make decisions based on them. The choice of network parameters although should be relevant for each specific objective. In this paper, we focus on the analysis of network parameters that are relevant for our self-management of lambda-connections proposal. This proposal consists of an automatic decision process to offload large … Show more

“…Our goal here is to observe which set of these parameters are relevant estimators to predict flow size. For that, we introduce a statistical methodology to validate our goal [55]. The following subsections present how network data was collected to our experiment as well as how our statistical methodology is comprised.…”

“…Since these decisions can be slow and error prone, we envision a move towards self-management approaches, which automatically move IP flows to lightpaths on the fly [6][7][8]. Network operators would only be required to initially configure the self-management process with decision policies, such as setting thresholds and priorities.…”

“…In [17], the authors characterize big flows by observing their size, duration, throughput (rate), and burstiness, as well as by examining their correlation considering the traditional 5-tuple flow definition: group packets with the same source and destination IP addresses, same transport protocol, and same transport protocol source and destination port numbers. Alternatively, [1] proposes a novel set of parameters to predict the traffic volume generated by elephant flows, which are summarized in Table 1. Note that volume prediction is employed in the self-management approach to reduce the cost of high-volume flows staying at the IP level, in terms of consumption of network resources, by detecting them in a timely manner so that they can be transferred to the optical layer.…”

“…This way, data flows can traverse IP/optical networks through either an optical path or a chain of routing decisions at the IP layer, where IP routers are interconnected with fiber links [1]. This is especially interesting for large flows for two reasons.…”
