asynchronous transfer mode (ATM) technology came into being in order to discuss why wireless ATM makes any sense or not. ATM technology is the result of efforts to devise a transmission and networking technology to provide high-speed integrated services: a single infrastructure for data, voice, and video. It evolved from the wide area into the local area, and then into the access loop. The foll...

High-performance wide-area networks are required to interconnect clusters of computers connected by local area and metropolitan area networks. Optical fiber technology provides long distance channels in the multi-gigabit per second range. The challenge is to provide switching nodes that handle these data rates with minimum delay, and at a reasonable cost. In this paper, we describe a packet swi...

Programming distributed applications is already potentially difficult, although tools exist to aid in their creation. Applications developed to communicate over local area networks can expect to enjoy highly reliable communications with minimal latency. However, such applications may no longer continue to perform as expected if moved to a wide-area network environment, due to the reduced perfor...

Software-defined network (SDN) is one of the most predominant technologies for networking in existing and next-generation networks. Therefore, this paper conducted to introduce a survey researchers who are interested exploiting dynamic tunneling technique optimize software-defined wide area (SD-WAN). The main purpose not only investigate related works with SD-WAN but also classify work accordin...

Network Transparency in Wide Area Collaborations

We describe a system to record and analyze ‘‘raw’’ Frame Relay and point-to-point T-1 packets. The data are captured by ‘‘eavesdropping’’ on the HDLC transmit and receive lines between the router and CSU/DSU. Analysis of the data provides circuit and application utilization information on a one-second or shorter time scale. Routine and custom reports are accessible through Web interfaces to pro...

the proliferation of information and communications technology (ict) along with the incremental growth in the use of cloud services, enterprise network and data center technologies in recent years, have caused unprecedented expansion of computer networks. however, the existing network architecture was not well designed to meet the requirements of today's needs. one of the most important pr...
