I have changed packet size to be 1400 on my production server and don't see any problem for now. I have not see javagames more than 358k till now. So as a temporary work around it's very good me. I don't have any other problem. But we provide access to our wap gw only to our customers, and we pretty sure that the network from them to us also let packets to be 1500 bytes.
Please provide me with your opinion if we such change in cvs Igor > -----Original Message----- > From: Stipe Tolj [mailto:[EMAIL PROTECTED] > Sent: Thursday, November 20, 2003 4:17 PM > To: Robert Hassing > Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] > Subject: Re: Problem with WAP-Gateway/File sizes > > > Robert Hassing wrote: > > > > Hi All, > > > > I have this problem with the WAP gateway I did setup. > > > > The problem is that a maximum of 254/255 packets can be > send concerning 1 > > file. > > This means that if I want to download a file with a size > higher as 143KB the > > transmission fails :-( > > > > The error I got is the following: > > > > In wapbox.log: > > PANIC: gwlib/octstr.c:1677: octstr_set_bits: Assertion > `value <= mask' > > failed. > > > > And in bearerbox.log: > > 2003-11-19 16:13:55 [7] ERROR: Couldn't send UDP packet > > 2003-11-19 16:13:55 [7] ERROR: System error 90: Message too long > > 2003-11-19 16:13:55 [7] ERROR: WDP/UDP: could not send UDP datagram > > 2003-11-19 16:14:05 [7] ERROR: Couldn't send UDP packet > > > > Is there a possibility to download files which are bigger > as appr. 143KB???? > > Robert, please don't cross-post to different mailing lists, we > consider this annoying! ;) > > ok, know regarding the size limitation. > > You are correct, Kannel implements WAP 1.2.1 features WTP-SAR > (segmentation and reassembly), which means a maximum of 256 segments > can be bound to one logical transmission. > > We would need a beast called ESAR (extended SAR) for having the > ability to pass "bigger chunks". > > This is known to be a "missing" feature, also for future aspects (ie. > for WAP GW proxying of big MMS) etc. > > Patches and contributions are highly welcome! -- you may consider > contacting the contributor of our WTP-SAR implementation and ask him > kindly if he has time and willing to contribute ESAR.
