Optimizing Internet Connection

braint — Tue, 25 May 2010 13:20:19 +0000

To achieve maximum performance from the computer, it is advisable that the internet connection be optimized. There are some ways that this can be achieved. A TCP Optimizer is a utility that may be downloaded from the Internet that effectively aids in the optimization of the internet connection. This can be done by selecting the “Optimal Settings” option and selecting the “Apply Changes” option so as to optimize the connection.

The optimization of the connection of the internet can be of essential benefit if it is carried out correctly. When the internet connection is tweaked, the amount of data that is received and sent will be defined and this will then help the user in knowing how to configure the system to accept the changes without the system and internet connection being slow. Although sometimes the optimizing can be negative with the desired results not being obtained or give drastic changes, it is one of the ways that improve the web browsing and downloads and this then makes it easier for work.

The main reason for altering the connection of the internet is because the internet may be slower than expected. When optimized carefully, the broadband speed increases and if it fails, the service provider may be alerted so that the problem may be rectified.

Latency, Bandwidth Delay Product & TCP Window

This article highlights on the TCP/IP factors and concepts on networking, which decides the most favorable TCP Receive Window. The factors are Bandwidth Delay Product, Latency and the TCP Window. TCP Window represents quantity of data that is outstanding, which is not acknowledged by the receiver and is able to be in a network. Following the data amount being sent, the sending party has to stop and wait for confirmation from the receiving party that something has been received. Because of this, the value is perhaps the only important setting when tuning and adding speed to the broadband connection of the internet. When the ‘handshake’ stage of the TCP begins, there is the negotiation of the TCP Receive Window every time.

The unique standard of the DARPA of TCP/IP has the RWIN or TCP Window, which limits at 64K. This is because the headers of TCP has 16-bits only for the value of RWIN, as well as 2^16=64K. The limits had to be attended to and the year 1992, saw a ‘TCP Options’ header annex, added by the RFC 1323, which permitted the expansion of the maximum size of the TCP Window, by including another byte to be like a ‘scale factor’ to the value of the RWIN. Latent or RTT is the rate of each data transfer, the same as TCP being largely determinable by the speed.

Additionally, the delay should be considered or the Round Trip Time, RTT, of every data packet. Every occasion a client PC requests a question to a server, there is the delay of the RTT until a response has been received. Data packets travel via several routers that have high traffic, which are sometimes congested and the light speed is always a limitation. The major distance on Internet communication is also considered. Bandwidth Delay Product or in short known as BDP, verifies the data amount that may be in movement in a network, the same as the RWIN.

The BDP is a bandwidth available product as well as the RTT or latency. It is a concept that is very important in a protocol that is window-based like the TCP, in the same way the throughput is obligated by this BDP. The TCP Window and the BDP limit the bandwidth connection and the latency of the product. The latency/RWIN value cannot be exceeded by a transmission. To be able to determine an optimal TCP Receive Window, utilize simply on of the recommended values of the SG TCP Analyzer.

Bits, Bytes and Bandwidth Quick Conversions

In the world of data communication, there is regular use of a specific kind of metric system to describe particular components and rates of computing actions. When dealing with the rate of data transfer, the bit is the base unit and it is a single binary digit that is equivalent to 1 or 0. A kilobit or kb represents 1000 bits as well as being equivalent to 10^3 bits while the megabit or mb is represents 10^6 or 1000,000 bits. The highest bit unit is the Gigabit or Gb which is 10^9 bits or 1,000,000,000 bits. Kilobits are normally used to measure the quantity of data being transferred per second within two telecommunication points. The value is represented as kilobits per second or Kbps.

The unit usually used when describing data storage or memory size, is the byte and one byte (b) is equivalent to 8 bits. Similarly, one kilobyte is equivalent to 1,024 bytes. Owing to computer architecture being in binary form, the bytes have to be exponents or multiples of two. Most manufactures of hard disks and newer models of BIOSes make use of decimal megabytes or 10^6, and this means that one kilobyte is 10^3 bytes or 1000 bytes.

Bandwidth is used as a measure of data amount that is able to be transmitted via a connection in a certain amount of time. It is sometimes referred to as the data transfer rate or baud rate and is represented in bits per second or bps. One kilobit in this case is equal to 1000 bits of bandwidth. DSO or Digital signal O is the standard used transmission of to the standard used transmission rate that is digital form and its rate 64 kbps. This is the bandwidth for standard telephone channels. 64 Kbps has a DSO multiple of 1 while a data rate of 128 Kbps has a DSO multiple of 2.

An illustration of bandwidth calculation is as follows; 1 byte has 8bits therefore if a PC receives 5KB of data or 5000 bytes per second, then it acquires 40,000 bps. This is calculated to by multiplying 5000 bytes by 8 bits which is equal to 40,000 bps or 40kbps. Bandwidth is related to capacity and it could be affected by the cables used for connection. The cables have a certain capacity which can allow transmission of only a particular amount of data. Bits, bytes and bandwidth are all related in one way or another and to get the value of each, the appropriate conversions should be carried out.

Internet Connection Speed

braint — Mon, 10 Aug 2009 08:58:42 +0000

Internet connection speed refers to the rate at which the amount of received and transmitted data by a specific user or computer spreads across the internet. This is all the inbound and outbound traffic in a computer. Bandwidth is commonly referred to as network bandwidth or digital bandwidth in computer science and networking and it is measured in bit/s. The more there is exchange of data in the networks the higher the energy that is taken up by a particular computer or user.

This means there may be numerous data exchange going to and from the computer that it may not be able to handle all of them. This will then result in the computer becoming very slow. The best way to make the computer and the bandwidth not to drag or clog the network is to have bandwidth usage caps that regulate the users from receiving and transmitting a lot of data. When this is done, the internet connection speed will cease to be slow and other users will not be impaired in their usage of the internet.

Internet service providers or ISPs can be able to track the bandwidth usage by checking how much data is passing through a specific connection or by recognizing the operation of specific machines. There are other software as well that can be able to monitor the internet bandwidth usage to allow the user to minimize and let the machine function at a faster rate.
