As stated in RFC 3286: "...endpoints must manage the conversion between bytes sent and received and TSNs sent and received, since TSN is per chunk rather than per byte". How does this affect the congestion control algortihm? ...
Is there a generic IP device name for windows similar to "eth0" used by Linux and Solaris? I am attempting to monitor SCTP traffic, which appears to be successful passing the ip address, but this means for every machine to use this application would changing to use the host address. Thanks ...
I am considering using SCTP instead of TCP for a p2p app written in C. Should I do it? Also how does the speed of SCTP compare to the speed of TCP? EDIT: I found that SCTP can be tunneled over UDP with the only problem being tunneled SCTP is not interoperable with untunneled SCTP. ...
I am planning to use SCTP for a embedded Linux project. Anybody has some comments on SCTP usage, mostly in one-to-many mode? Did it beat using a home-made UDP-based equivalent solution? I control the network environement and all devices involved, so compatibility is not an issue. ...
Hello Everyone, I'm working on a p2p app that uses hash trees. I am writing the hash tree construction functions (publ/4 and publ_top/4) but I can't see how to fix publ_top/4. I try to build a tree with publ/1: nivd:publ("file.txt"). prints hashes... ** exception error: no match of right hand side value [67324168] in function ...
I recently checked out the book "UNIX Network Programming, Vol. 1" by Richards Stevens and I found that there is a third transport layer standard besides TCP and UDP: SCTP. Summary: SCTP is a transport-level protocal that is is message driven like UDP, but reliable like TCP. Here is a short introduction from IBM DeveloperWorks. Honest...
Hi I'm using the experimental asio sctp library. (code.halssoftware.com/index.php/p/boostasiosctp/source) It's pretty easy to use like the other networking stuff in asio. The one problem I have is that I want to use the PPI field in SCTP data chunks - but I can't figure out how to get that information from the asio sctp interface. It ...
Hello, I'm looking for a .NET implementation of the SCTP protocol. A component or a C#/F# source code would be preferred, however if no such thing is available a VB.NET source code could probably work too. The project I'm working on is targeting the .NET Framework v3.5 but anything that works with .NET v2 to v4 is welcome. ...
What kind of SCTP support is there on various Windows versions? ...
Hi, I'm trying to get SCTP to work. I wrote a simple client and server and tested it with localhost(127.0.0.1 as server). it works perfectly, the server bind a port , listen and accept a socket and the client connect to the server and send it a message. When I set up my sctp server in a remote server(eg. 192.168.0.200) , the client get...
SCTP has native multi-homing support which if I understand it correctly will automatically reroute your packets over a secondary NIC if the primary interface goes down. I duplicated this functionality with TCP by writing a custom routing deamon to modify the routing tables if my primary NIC goes down. I would like to try using SCTP ins...
This is related to the question: SCTP with Multihoming as a Drop In Replacement for TCP I have a simple echo client / concurrent server app that ran perfectly fine using TCP. I could pipe a file to stdin on the client and the client would receive all the data back, call select which would return 1 indicating the socket was readable, t...
Hi, I am developing a walkie-talkie application for Android, and would like to know whether RTP and/or SCTP is natively supported in the latest version of android SDK. From whatever I have dug-up so far, the answer is no. It seems that support for SCTP is coming in JDK 7. But then, I am not sure how this will work with my android de...
Hello What configure options a should use to compile mpich2 (ver 1.1.1p1 or 1.2.1p1) with sctp ?

hello, I try to make an ss7 application using openss7 and sctp. I made some simple application using SCTP. the part of the source code is like below : sock_srvr = socket(PF_INET, SOCK_DGRAM, IPPROTO_SCTP); if ( sock_srvr == -1 ) { perror("socket"); exit(0); } and it return socket: Protocol not supp...
hello, is there anyone who have tried openss7?. I cannot find /dev/bssap, where can i find it ?. Thanks. ...
Hello everyone, is there anyonve have used openss7 before ?. well, I am trying to implement MTP with mtpi interface. so i use I_LINK to link between M2PA and MTP. But I got some error, ioctl invalid argument. Do you have some suggestion for me ?. Thanks. your answer will be very helpful for me. int a1 = open("/dev/sctp_n", O_RDWR...
Hello, is there anyone in this forum who have experience with openss7 before ?. Or maybe stil developing with openss7 ?. I need to discuss something, since it's difficult to find the solution... ...
We have an application that uses two types of socket, a listening UDP socket and an active SCTP socket. At certain time we have scripts running on the same machine that have high IO activities (such as "dd, tar, ..."), most of the time when these IO heavy applications run we seem to have the following problems: The UDP socket closes T...
Hello everyone, I have downloaded this m3ua package from http://sourceforge.net/projects/m3ua/ and i have been getting this error while doing make sctp: struct sctp_event_subscribe has no member named sctp adaptation layer Any clues? Thanks! ...
