bing 1.3.5

bing is an application written by Pierre Beyssac which measures the RAW bandwidth of a remote network link. Let me ad some precisions. By "remote" I mean a link not directly connected to your computer. For instance you can measure the bandwidth of a link between you ISP and the rest of the internet. By "RAW" I mean that you can measure the intrisic bandwidth of the link not whats left once the other users have taken their share. So even if a link is saturated and you can only get 1KBps out of it bing will be able to tell you whether it is a 128Kbps link or 256Kbps or more. Now dont expect miracles.
bing uses ICMP of course ! bing sends Echo Request packets of different sizes and analyses the resulting RTT change. RTT vary a lot from one measure to the other so bing has to make multiple measures each being measured as accurately as possible and then it takes the minimum RTT for each host and packet size. For more information on bing have a look at the Readme file.
There are two versions of the source. The version 1.0.4 is the latest stable official release which was developped by Pierre Beyssac but it only runs on Unix. The version 1.1.3 is a derived development release which I ported to Wind32 platforms. Eventhough this is a developpement release I think it is stable enough to be used instead of the 1.0.4 release. For the users of the 1.1.2 release on Win32 I really recommend the upgrade to this 1.1.3 release as I greatly improved the precision of the RTT measurements.
Enhancements:
- Putting some Win32 code back in.
- Update of the bing man page.
- Update of the Readme file.
- Enhanced the makefile.
