Implementation of a Stream-Based IP Flow Record Query Language
Internet traffic analysis via flow records is an important task for network operators. There is a variety of applications, targeted at identifying, filtering or aggregating flows based on certain criteria. Most of these applications exhibit certain limitations when it comes to the identification of complex network activities. To overcome some of these limitations, a new flow query language has ...
متن کاملDesign of a Stream-Based IP Flow Record Query Language
Analyzing Internet traffic has become an important and challenging task. NetFlow/IPFIX flow records are widely used to provide a summary of the Internet traffic carried on a link or forwarded by a router. Several tools exist to filter or to search for specific flows in a collection of flow records, however the filtering or query languages that these tools use have limited capabilities when it c...
متن کاملFitting MMPP to IP Stream
Markov Modulated Posson Process (MMPP) is a good model of Internet traffic. We take an IP trace and fit an MMPP to it using an algorithm recently published in a Journal. It is observed that trace generated using the MMPP model of the original trace has a distribution similar to the original trace. This is seen in the form of a linear quantile-quantile plot. Average queuing delay with data trace...
متن کاملStream Descriptions and Content based Discarding in IP-Routers
There is a growing set of UDP based applications using inadequate or none congestion control algorithms (i.e., the flow doesn’t throttle back upon receipt of congestion notification). Such UDP applications include streaming applications like packet voice and video, and also multicast bulk data transfer [5]. Congestion avoidance algorithms in routers are not able to cope with these flows and thi...
متن کاملPerformance Analysis of Flow-Based Label Switching: The Single IP Flow Model
A closed-loop queueing model of flow-based label switches, supporting label reservation protocols of different label-setup and release policies, is presented. This model can emulate the behavior of TCP under the label switch when the maximum window size has been achieved and the packet loss rate is negligible. The label-setup policy is that the IP controller does not start to set up a label unt...
