sorry for the late reply, the systems are not readily accesable to me.

I will try to answer the questions here

- network cards are configured to be auto on speed and on flow control
- one single switch used for B1, B2 and B3
- one firewall for the whole B company, no specific configs for the OSR systems
- don't know how to get errors on the network, should I just run
Code:
netstat -s

the output is quite lengthy, which section should I post here?


- traceroute outputs:
From B1 to A (slow)
Code:
traceroute to 12.222.222.2 (12.222.222.2), 30 hops max, 40 byte packets
 1  11.22.33.50 (11.22.33.50)  0.807 ms  0.635 ms  0.684 ms
 2  123.22.23.1 (123.22.23.1)  3.913 ms  4.078 ms  3.943 ms
 3  123.22.23.13 (123.22.23.13)  3.780 ms  4.198 ms  4.057 ms
 4  123.22.23.14 (123.22.23.14)  7.287 ms  6.699 ms  7.058 ms
 5  12.222.222.2 (12.222.222.2)  6.731 ms  6.942 ms  6.553 ms

From B3 to A (fast)
Code:
 
 traceroute to 12.222.222.2 (12.222.222.2), 30 hops max, 40 byte packets
 1  11.22.33.50 (11.22.33.50)  1.089 ms  0.857 ms  0.768 ms
 2  123.22.23.1 (123.22.23.1)  4.759 ms  6.764 ms  9.643 ms
 3  123.22.23.13 (123.22.23.13)  27.320 ms  13.411 ms  3.507 ms
 4  123.22.23.14 (123.22.23.14)  6.998 ms  7.296 ms  6.751 ms
 5  12.222.222.2 (12.222.222.2)  6.911 ms  9.518 ms  37.746 ms

They look very similar to me.

Please tell me what else is needed to pinpoint the problem?
Thanks in advance.

esreverse

ESREVERSE:(1)							   User Commands						     ESREVERSE:(1)

NAME

       esreverse - reverse an es stream

SYNOPSIS

       esreverse [switches] <infile> <outfile>

DESCRIPTION

	      TS tools version 1.11, esreverse built Nov 11 2008 17:15:47

	      Output a reversed stream derived from the input H.264 (MPEG-4/AVC) or H.262 (MPEG-2) elementary stream.

	      If output is to an H.222 Transport Stream, then fixed values for the PMT PID (0x66) and video PID (0x68) are used.

   Files:
       <infile>
	      is the input elementary stream.

	      <outfile> is the output stream, either an equivalent elementary

	      stream, or an H.222 Transport Stream (but see -stdout and -host below).

   Switches:
       -verbose, -v
	      Output additional (debugging) messages

       -quiet, -q
	      Only output error messages

       -stdout
	      Write output to <stdout>, instead of a named file Forces -quiet.

       -host <host>, -host <host>:<port>
	      Writes  output (over TCP/IP) to the named <host>, instead of to a named file. If <port> is not specified, it defaults to 88. Implies
	      -tsout.

       -max <n>, -m <n>
	      Maximum number of frames to read

       -freq <n>
	      Specify the frequency of frames to try to keep when reversing. Defaults to 8.

       -tsout Output H.222 Transport Stream

       -pes, -ts
	      The input file is TS or PS, to be read via the PES->ES reading mechanisms

       -server
	      Also output as normal forward video as reversal data is being collected. Implies -pes and -tsout.

       -x     Temporary extra debugging information

   Stream type:
	      If input is from a file, then the program will look at the start of the file to determine if the stream is H.264 or H.262 data. This
	      process may occasionally come to the wrong conclusion, in which case the user can override the choice using the following switches.

       -h264, -avc
	      Force the program to treat the input as MPEG-4/AVC.

       -h262  Force the program to treat the input as MPEG-2.

	      TS tools version 1.11, esreverse built Nov 11 2008 17:15:47

	      Output a reversed stream derived from the input H.264 (MPEG-4/AVC) or H.262 (MPEG-2) elementary stream.

	      Write output to <stdout>, instead of a named file Forces -quiet.

       -host <host>, -host <host>:<port>
	      Writes  output (over TCP/IP) to the named <host>, instead of to a named file. If <port> is not specified, it defaults to 88. Implies
	      -tsout.

       -max <n>, -m <n>
	      Maximum number of frames to read

       -freq <n>
	      Specify the frequency of frames to try to keep when reversing. Defaults to 8.
