Introduction
Twenty-first century communications will be dominated by intelligent high-speed information networks. The rapid growth of high-speed networks has led to many technological as well as social developments. As the networks supporting these services shift from the experimental phase to commercial operation, the pricing of limited resources will become an important problem. In this paper, statistical Multiplexer with QOS parameter control is implemented using VLSI design technologies. In communications systems by far the most common form of multiplexing is that of time division multiplexing (TDM). In this technique, the entire capacity of the shared transmission medium is allocated to each source in turn for a short duration sufficient for the source to transmit a brief burst of information of fixed length. The packets transmitted over a channel result from simultaneous active connections, each sending its packets as part of a communication among two or more hosts. The packets of the different connections are intermingled on the link — for example; a packet is transmitted for one connection, then a packet for a second, another for the first, then two packets in a row for a third, and so forth. This intermingling is referred to as “statistical multiplexing” [1].
Efficient use of available bandwidth without sacrificing quality is a prime concern for any broadcaster or operator. A statistical multiplexing system takes advantage of the variable bit-rate nature of data and the statistical probability that not all channels will peak in bit-rate demand at exactly the same time. This technique allocates bandwidth to input channels in response to their needs and try to providing the better quality of service (QoS); high-speed cha...

Enclosed is a rough high-level conceptual view of the communication channels. This is very preliminary as we don't what suitable devices we can use for multiplexers, demux, and converters. The idea is to design a full-duplex serial com link between point A and B. The bandwidth is limited in the copper wiring (telephone line) probably would not go any higher than 115 kbps using a modem a constraint distance of 5 miles.
Multiplexing will gather the data from the source host and give that data some header information. This data will be created into segments by demultiplexing and then be sent to the 3rd layer (Network layer). So to summarize multiplexing will gather data and give it header information and demultiplexing will create segments and sent them to the network layer. Now with flow control that will relate with multiplexing, mainly because it can take multiple data streams and combine them into one shared stream, making that a form of data flow control. Now as far as error checking that will relate to the frames of the data. The logical link control will use a frame check sequence (FCS) to check the frame to see if there is any problems with it. If it detects an error during the frame check sequence then the frame will be discarded and the data will be passed on to the network layer. With this all being said this will mainly be used in the OSI model since the logical link control is the sub-layer for the data link layer. (The other sub layer being MAC) Without the logical link control or 802.2 then the data link layer wouldn’t function

Lab 1 demonstrates the capabilities of congestion control algorithms implemented by Transmission Control Protocol (TCP). It provides three scenarios to simulate these algorithms and will later compare the results.
In this lab, we used Transmission Control Protocol (TCP) which is a connection oriented protocol, to demonstrate congestion control algorithms. As the name itself describes, these algorithms are used to avoid network congestion. The algorithms were implemented in three different scenarios i.e. No Drop Scenario, Drop_Fast Scenario and Drop_NoFast Scenario.
After compression, the structure data, audio and video must be multiplexed. A number of compressed TV signals are combined by a multiplexer and put unto a shared transition medium. This is done by one of the two possible kinds of multiplexers that result in either a transport or a program stream, which is suited for secure transmission paths since it can contain large amounts of information. In addition multiplexing can be done using various methods. Time division multiplexing allocates a distinct time interval for each channel in a set; with the help of synchronization and a fixed interval order the channels take turns using the common line.
My knowledge of engineering is reasonable and includes transformer substations, power plants, power distribution and transmission systems, industrial motor control and PLC programming, protective relay coordination, FACTS devices, grounding systems, Matlab programming and project management. In addition, I possess practical experience performing power flow, short-circuit and relay coordination analyses while using a power system modelling software such as ETAP, EDSA, DigSilent and CYME. Consequently, the aforementioned experience and solid engineering education along with your training will allow me to provide support to operating and new

Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.

The uses of Digital Signal Processing in communications has become so large scale that nearly any form of analog communication is considered obsolete. Today, nearly any form of communication used, aside from verbal communication, relates to Digital Signal Processing. Some of the more prominent uses for DSP in communications are; local area networks, cell pho...
A high speed Internet connection is required to stream video. The Netflix Help Center recommends an Internet connection speed of 5.0 Megabits per second (Mbps) for HD video ("Internet Connection Speed Recommendations") Today most American households have access to broadband speeds capable of high-definition video. According to Anne Neville of the National Telecommunications and Information Administration, 98% of Americans have access to broadband speeds of six megabits per second and 83% to speeds of twenty five Mbps or more (Neville). These speeds are more than adequate for HD quality video streaming. With the current broadband initiatives in place this should continue to improve in coming years, along with the possibility of even greater speeds. Beginning in November 2013, Cox Communications began offering increased Internet connectio...

It has been observed from the feedback of current users that Jio bandwidth fluctuates a lot because of uneven demand –supply gap and this leads to questioning about reliabity of the services provided by the Jio.
