- Analyzing TCP Flow Arrivals
- This paper studies the TCP flow arrival process, starting from the aggregated measurement at the TCP flow level taken from the campus network. After introducing the tools used to collect and process TCP flow level statistics, the statistical properties of the TCP flow inter-arrival process are analyzed. It creates different...

- Oscillations With TCP-Like Flow Control in Networks of Queues
- This paper considers a set of flows passing through a set of servers. The injection rate into each flow is governed by a flow control that increases the injection rate when all the servers on the flow's path are empty and decreases the injection rate when some server is congested....

- TCP Westwood Simulation Studies in Multiple-Path Cases
- Best-effort traffic has been the dominant traffic type in the Internet, and TCP has been playing the major role for carrying such traffic. Internet is again moving toward more reliable and robust network services including QoS. Provisioning multiple paths as backup routes is one of the feasible solutions to designing...

- Network Monitoring Using Traffic Dispersion Graphs (TDGs)
- Monitoring network traffic and detecting unwanted applications has become a challenging problem, since many applications obfuscate their traffic using unregistered port numbers or payload encryption. Apart from some notable exceptions, most traffic monitoring tools use two types of approaches: keeping traffic statistics such as packet sizes and inter-arrivals, flow counts,...

- Flow-Slice: A Novel Load-Balancing Scheme for Multi-Path Switching Systems
- Multi-Path Switching Systems MPS are intensively used in the state-of-the-art core routers. One of the most intractable issues is how to load-balance traffic across its multiple paths while not disturbing the intra-flow packet orders. In this paper, based on the studies of tens of real Internet traces, a novel scheme...

- Dimensioning of Wireless Mesh Networks With Flow-Level QoS Requirements
- This paper studies dimensioning of wireless mesh networks with elastic traffic subject to flow-level performance constraints. The objective of the dimensioning is to provide order-of-magnitude estimates of the required transmission resources in the network. The results can be used to evaluate the feasibility and sensitivity of a given network scenario,...

- Dynamic Load Balancing Without Packet Reordering
- Dynamic load balancing is a popular recent technique that protects ISP networks from sudden congestion caused by load spikes or link failures. Dynamic load balancing protocols, however, require schemes for splitting traffic across multiple paths at a fine granularity. Current splitting schemes present a tussle between slicing granularity and packet...

- Modeling Internet Backbone Traffic at the Flow Level
- Modeling the Internet traffic is an important issue. It is unlikely that one will be able to understand the traffic characteristics, predict network performance (e.g., for QoS guarantees or Service Level Agreement definition), or design dimensioning tools without analytical models. The successful evolution of the Internet is tightly coupled to...

- Securing SMTP Message Flow Between Different Exchange Server 2007 Organizations
- It is necessary to protect SMTP traffic between different Exchange Servers. Securing SMTP traffic between different Exchange 2007 organizations is much simpler than in previous versions of Exchange and one don't need a complicated solution like implementing IPSEC between these Servers. This paper shows how to secure SMTP message flow...
