Acceptable Bit Error Rate
need a tool software or otherwise (preferably software) that will allow me to test Bit Error Rates on an Ethernet Network. I am using a software tool that I did not write and do not have access to the source of to introduce Bit Errors into an Ethernet Network. I am currently trying to test to see whether this software does what it actually is supposed to do, so that it can be used in some network simulations. I know bit error rate measurement there are hardware testers like the FireBERD but it would be great if someone had some software that could do it. Although based on what I'm reading here http://www.wireshark.org/faq.html#q7.9 I don't have much hope. networking wireshark packet-loss share|improve this question edited Aug 19 '11 at 17:38 Diogo 19.8k47117193 asked Aug 19 '11 at 17:22 rhololkeolke 243312 If you have a Mac handy, it might be worth trying Wireshark on that. I've never seen Wireshark capture CRC data on any Windows machines. –sblair Aug 19 '11 at 18:21 add a comment| 5 Answers 5 active oldest votes up vote 2 down vote If you're running *NIX you can check /proc/net/dev to see stats about errors. It's vague about what errors, but according to this post on Stackoverflow it does record CRC errors. share|improve this answer answered Aug 19 '11 at 18:49 charlesbridge 936611 This is interesting and potentially useful, however, the errors are at a packet level and I need something that will give me errors on the bit level. In our initial testing we were using Wireshark and looking at packets that we knew were incorrect and trying to count bits. Obviously this is not going to work for a lot of packets so we need software that can detect errors on the bit level and give us statistics based on them. –rhololkeolke Aug 22 '11 at 16:32 add a comment| up vo

to another. Systems for which bit error rate, BER is applicable include radio data links as well as fibre optic data systems, Ethernet, or any system that transmits data over a network of some form where noise, interference, http://superuser.com/questions/325328/how-to-test-bit-error-rates-on-ethernet-networks and phase jitter may cause degradation of the digital signal. Although there are some differences in the way these systems work and the way in which bit error rate is affected, the basics of bit error rate itself are still the same. When data is transmitted over a data link, there is a possibility of errors being introduced into the system. If errors are introduced into the data, then the integrity of the system may be compromised. http://www.radio-electronics.com/info/rf-technology-design/ber/bit-error-rate-tutorial-definition.php As a result, it is necessary to assess the performance of the system, and bit error rate, BER, provides an ideal way in which this can be achieved. Unlike many other forms of assessment, bit error rate, BER assesses the full end to end performance of a system including the transmitter, receiver and the medium between the two. In this way, bit error rate, BER enables the actual performance of a system in operation to be tested, rather than testing the component parts and hoping that they will operate satisfactorily when in place. Bit error rate BER definition and basics As the name implies, a bit error rate is defined as the rate at which errors occur in a transmission system. This can be directly translated into the number of errors that occur in a string of a stated number of bits. The definition of bit error rate can be translated into a simple formula: If the medium between the transmitter and receiver is good and the signal to noise ratio is high, then the bit error rate will be very small - possibly insignificant and having no noticeable effect on the overall system However if noise can be detected, then there is chance that the bit error rate will need to be considered. The main reasons for the degradation of a data channel and the correspondin

The bit error ratio (BER) is defined as the probability that a bit is received in error when, between transmission and reception, one or more bits are changed (e.g., a binary 0 is transmitted and a binary 1 is received). This measured ratio is affected by many factors, including noise, interference, distortion, attenuation, and jitter. Depending on the telecommunication protocol, BER requirements might vary from 1x10-6 to 1x10-12.

It will coexist with currently active techniques like non-return-to-zero (NRZ). Let’s take a closer look at the principles behind BER testers (BERTs) and the challenges that the key players in the market are facing—along with the products they are offering to cover the need for data transmission using different forms of signal modulation.
