Traffic classification plays an important role in many aspects of network management such as identifying type of the transferred data, detection of malware applications, applying policies to restrict network accesses and so on. Basic methods in this field were using some obvious traffic features like port number and protocol type to classify the traffic type. However, recent changes in applicat...

It has been understood for some time that arbitrary data, including the communications associated with malicious backdoors and Trojan horses, can be tunnelled by subverting the HTTP protocol. Although there are a number of demonstration programs openly available, the risks associated with this vulnerability have not been characterised in the literature. This research investigates the nature of ...

background: more than 20% of deaths from traffic crashes are related to pedestrians. this figure in tehran, the capital of iran, reaches to 40%. this study aimed to determine the high-risk areas and spatially analyze the traffic crashes, causing death to pedestrians in tehran.   methods: mapping was used to display the distribution of the crashes. determining the distribution pattern of crashes...

The increasing popularity of HTTP adaptive video streaming services has dramatically increased bandwidth requirements on operator networks, which attempt to shape their traffic through Deep Packet Inspection (DPI). However, Google and certain content providers have started to encrypt their video services. As a result, operators often encounter difficulties in shaping their encrypted video traff...

A key aspect of traffic classification is the early identification of individual flows which may utilise strategies such as ephemeral ports and transport later encryption to ‘hide’ on the network. This paper focuses on P2P and HTTP – the two main producers of network traffic – to determine the characteristics of their individual flows. We propose a heuristic based classification system to disti...

background and aim: injuries from traffic accidents are a major public health problem, and the third leading cause of mortality in people aged 1 to 40 years. each year 31.8 persons per hundred thousands of iranians are killed in car accidents. neighboring of north khorasan province with razavi khorasan, a province with a lot of pilgrims caused a large number of passengers travel via north khora...

This memo applies the Upgrade mechanism in HTTP/1.1 to employ Transport Layer Security (TLS) over an existing TCP connection. This allows unsecured and secured traffic to share the same well known port (in this case, http: at 80 rather than https: at 443). This also enables "virtual hosting," by allowing a single HTTP + TLS server to disambiguate traffic intended for several hostnames at a sing...
