Follow this procedure and the software file download for installing TCPIP protocol on DOS computers. Windows 3.11 Tcp Ip' title='Windows 3.11 Tcp Ip' />Youre getting warmer. Its almost 8. 5s without the IPSec and over 9s with it. Whats the big deal with a 1s difference Well, extrapolate that increase, lets say its 1. To put it another way, youve lost 1. You might think that these matters are pointless in our high bandwidth world but lets not forget that for the global majority, internet connectivity still looks like a 9. All these bits and Bytes matter to Facebook and Google too, when youre dealing with hyper scale connection and data rates, shaving off even 0. SPDY is a good example of efforts to help with this. Also, when I want to understand something, I really want to understand it. When someone technical complains about network performance, I like to have some real figures ready as to why they will never, ever get 1. Mb of data down that Fast Ethernet link in 1 second. It fills me with confidence knowing the answers I provide to questions of bandwidth and performance are not based on hypothetical fantasy albiet still caveated with plus application overheads.

By the way, if youre wondering why you cant shove that 1. GB file over a 1. Gb link at a decent speed, thats a whole other ballgame, very well explained by Brad Hedlund here. Skip to the end for the summary if you really cant face the math. Assumptions. The following assumptions have been made when formulating these calculations No retries, packet losses or other events occur. One way, one to one host communication data and overhead. An IP MTU of 1. 50. Bytes. A host TCP MSS of 1. Bytes. TCP IP packet headers of 4. Bytes no TCP optionsUse of a full duplex communications medium, i. Where division of the data into the maximum packet size results in a fraction, a packet for that remaining data must still be transmitted so we always round up when calculating the number of packets. Units of Measurement. The abbreviations used with the datatraffic values in this article are metric prefixes aka SI prefixes indicating decimal multiplication rather than binary prefixes based on powers of two where 1kbit 1. B 1,0. 00 Bytes 8,0. MB 1,0. 00,0. 00 Bytes 8,0. A few things to remember Serial line speeds are typically quoted using binary prefixes, so a 2. Mb E1 is actually 2. Mb using metric prefixes. Ethernet speeds are typically quoted using metric prefixes, so a 1. Mb Ethernet link is exactly that 1. Linux commands display file size information using metric prefixes. However, using a human readable or h switch normally results in output using binary prefixes which is rather confusing. Crystal Reports 9 Serial. Windows displays file sizes using binary prefixes. To make accurate calculations, view the file properties or use a command prompt to discover the file size in Bytes and apply the metric prefix. Most other storage systems use binary prefixes. Hard drive manufacturers typically use metric prefixes which means they appear smaller than specified when capacity is displayed using binary prefixes. Bits Bytes. Byte 8 bits. File sizes are normally quoted in Bytes. Linux commands display file size information in Bytes. Link speeds are quoted in Mb Megabits per second, not Mega. Bytes, thus ignoring all overheads itll take 8s to move 1. MB Mega. Byte over a 1. Mb Megabit per second Fast Ethernet link. Other Overheads. TCPIP handshake overheads have been ignored as these are negligible. Ethernet transmission overheads have been ignored too for now but Ill borrow some figures from Wikipedia in the summary to demonstrate how you can easily calculate that affect too. For the sake of simplicity Ive ignored Ethernets preamble, start frame delimeter and interpacket gap when calculating its overhead. Overhead Calculations. Ive used five data sizes here to demonstrate that the overhead remains fairly consistent as long as the amount of data exceeds the common IP MSS of 1. Bytes 1. B of Data. This might seem unlikely but programs such as Telnet and SSH transmit a packet for every character sent or received during a session. B can be contained in 1 packet not exceeding 1. Bytes the default TCP MSS1 x 4. Bytes of TCP IP headers equals a 4. Byte, 4,1. 00 TCPIP overhead. Thus, 4. 1Bytes of data is actually transmitted over the network. B of Data. 1k. B 1,0. Bytes can be contained in 1 packet not exceeding 1. Bytes 1,0. 00 1. Bytes of TCP IP headers equals a 4. Byte, 4 TCPIP overhead. Thus, 1,0. 40. Bytes of data is actually transmitted over the network. B of Data. 20k. B 2. Bytes must be split into 1. Bytes 2. 0,0. 00 1. Bytes of TCP IP headers equals a 5. Byte, 2. 8 TCPIP overhead. Thus, 2. 0,5. 60. Btyes of data is actually transmitted over the network. B of Data. 48. 0k. B 4. 80,0. 00. Bytes must be split into 3. Bytes 4. 80,0. 00 1. Bytes of TCP IP headers equals a 1. Byte, 2. 7. 4 TCPIP overhead. Thus, 4. 93,1. 60. Bytes of data is actually transmitted over the network. MB of Data. 1MB 1,0. Bytes must be split into 6. Bytes 1,0. 00,0. Bytes of TCP IP headers equals a 2. Byte, 2. 7. 4 TCPIP overhead. Thus, 1,0. 27,4. 00. Bytes of data is actually transmitted over the network. Summary. So, as demonstrated, for data payloads in excess of the common TCP payload maximum segment size the MSS of 1. Bytes, the TCP over IP bandwidth overhead is approximately 2. This equates to an efficiency of 9. However, keep in mind that for very small data payloads common with applications such as Telnet, TN3. 9 Paint Shop Pro 7 Full Version. SSH the TCP over IP bandwidth overhead can be higher than 4,0. If you add Ethernet and VLAN tagging into the mix see the calculations from Wikipedia here then the throughput of a 1. Mb link is 1. 00 X 0. TCPIP efficiency x 0. Ethernet with tagging efficiency which equals 9. Mbps, which I assume means the combined efficiency is 9. Add in your security protocol AES would drop the figure to 8. If youre not filling every packet to the brim you can imagine the loss can get even higher pretty quick. With HTTP for instance, a large number of headers, large cookie values, multiple cookies and the like can literally consume a further 2. If you are looking for an argument as to why you should use Jumbo frames in a LAN environment, I dont think there is one still, like I said, in some circles ever matters.
