Enclosed is a draft of a proposed activity on traffic stats and metric. Through many discussions, the idea has evolved and developed around an idea to conduct a large scale effort of stat collection and analysis on a European Scale. Over the past few months, we have collected information on current activities throughout Europe in this area, and this draft reflects many of your thoughts and ideas on how to carry out such a project. This document is a draft and comments are encouraged. Some of the ideas and deliverables are not complete (software suggestions) need further input and insight in order to define/refine them in full and as a first step, it is proposed to proceed on the wg-qmn list. Cheers, Ariel --------------------------- original document --------------------------------- Project name: TERENA Task Force on European Traffic Studies Justification The problem of network traffic growth prediction may be attributed to a plethora of difficulties associated with network operation. There is one common ground, however, that which is the end result: performance. Many TERENA members currently collect basic statistics on their own network's performance and traffic flows. Typically, this includes measurement of throughput, delay and availability. However, the only baseline against which networks evaluate performance is their own past performance metrics. There is no data available for national level comparisons with other networks' performance. It is increasingly vital for both users and providers to provide information on end-to-end performance. Such information is beyond the realm of what is currently undertaken by individual networks. The project objective is to collect and analyze data which will enable focusing on the causes of decreased performance and proposing corrective actions. These activities include the development a mechanism and structure for collecting statistics of traffic loads on an end-to-end international level, measurements of delays, flow capacity and packet loss information. Objectives The vacuum created in national-level statistics/metric collection has significantly complicated planning by member countries and service providers. While details traffic and performance measurements are essential to identifying the causes of network problems and formulating corrective actions, it is trend analysis and accurate network/system monitoring which permit network managers to identify "hot spots", predict problems before they occur and identify ways to avoid them by efficient deployment of resources and optimizing of network configuration. As the explosive growth and dependence on the Information Infrastructure continues, it is critical that mechanisms be established to enable infrastructure planning and analysis. This proposal describes a possible mechanism for undertaking a project to concentrate current efforts. It is proposed to address these problems on two levels of relevance: 1. significance to analysis of network performance 2. relevance to Internet settlements These activities will include cross-European measurements of total traffic through specific links and the mapping of reachable destinations covered by a route, Delay measurements, flow capacity, continental averages of hops, and rate of packet loss monitoring. Deliverables: … Software kit for all participating members - for total trafic stats: TCP dump samples, router stats, Network Probe Daemon - for delay measurments: ping-based utilities, Treno , - for packet loss stats: To be discussed - Hope counts: traceroute … Report: TF-ETM Guidelines for setting up a Stats-collection operation compatible with the rest of the project - guidelines for peering - topology of participating links … Web site concentrating the European statistics collected - General database with all raw data - various "views" of the data - analyzed data, patterns, related papers, ongoing work etc … Report: Summery of network patterns and problems identified by the stats collection - … Final report on Stats: analyzed results of the metrics and guides for immediate possible corrective steps. … Results of traffic model: A predictive report on network patterns and identification of necessary deployment of resources to meet these challenges Resource Requirements: ?
