The Wireless Campus project is a research and development initiative jointly performed by the ""CSP"" Italian Information Communication Technology research centre and the ""Environment Park"" technology park. Its primary objective consists in deploying an 802.11b compliant Wireless Local Area Network (WLAN) inside the technology park and other regional sites, both to sustain a real distributed environment scenario of service and create a permanent research laboratory on mobile networks technologies. The plant is projected as a distributed network including a core hot-spot (in Environment Park) that has aggregating function for other hot-spots in regional territory, all connected through a cabled backbone to the primary one.
This paper focuses on passive measurements of TCP traffic, main component of traffic. In particular, it proposes a heuristic technique for the classification of the anomalies that may occur during the lifetime of a connection. Since TCP is a closed-loop protocol that infers network conditions and reacts accordingly by means of losses, the possibility of carefully distinguishing the causes of anomalies in TCP traffic is very appealing and may be instrumental to the deep understanding of TCP behavior in real environments and the protocol engineering.
