The use of multimedia service applications is growing rapidly on the Internet. These applications are generating a huge volume of network traffic, which has a great impact on network performance and planning. For various purposes, obtaining information on multimedia service traffic is important. However, traditional analysis methods based on well-known ports cannot be used to analyze such traff...

quality of service (qos) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. the differentiated services architecture (diffserv) allows providing quality of service to users. the major diffserv premise is that individual flows with sim...

Draft traffic impact assessment (TIA) guidelines for various landuses in general, and for high traffic generating buildings in particular, were published in Iran in the middle of 2016. In formulating that report the Traffic Committee of the Iranian Building Engineering Order reviewed international experience, including that of Australia. Traffic impact assessment started in Australia in the 196...

Drivers in urban neighborhoods who patrol streets, seeking inexpensive on-street parking create a significant fraction of measured traffic congestion. The pool of drivers patrolling at any time can be modeled as a queue, where ‘queue service’ is the act of parking in a recently vacated parking space and queue discipline is SIRO – Service In Random Order. We develop a queueing model of such driv...

Traditionally, Internet service providers provide the same level of service (the so-called "best-effort" service) to all kinds of network traffic. For traditional non-real-time Internet traffic such as File Transfer Protocol (FTP) data, the best-effort service has not been a problem. However, the result of today's tremendous growth of Internet not only involves traffic increasing in volume, but...

priority queues have a great importance in the study of computer communication networks in which different types of traffic require different quality of service standards. the discrete-time non-preemptive priority queuing model with priority jumps is proposed in this paper. on the basis of probability generating functions mean system contents and mean queuing delay characteristics are obtained....

globally around 38 million people die each year as a result of non communicable diseases (ncds) in which 42% (~ 16 million) are premature deaths (below the age of 70). nine voluntary global targets were set by world health organization to control above mentioned premature deaths. iran added 4 more targets to it, including 20% reduction in the mortality rate due to road traffic injuries. the nee...
