Hi all, I'm working on a large file transfer(P2P) in UDP air application. I want to connect client and server using TCP. Can anybody tell me how to connect both both in TCP. Thank you.
If my applications run on a same computer or even on different computers in a same LAN and need intense and quick communication, it seems illogical for me to use text-encoded web services and HTTP. I could possibly use IP/TCP/UDP sockets and invent my own protocols, but believe there is a standard way for .Net applications to send/receive object…
I'm writing an iphone apps that receive data from an udp socket i can dispay what i receive using NSDATA description but is in hex format and for example it look like this:

We use socket.send(packet) function in java to send a "packet" to a given port.
My problem is that i have to send a packet to a shutdown system using UDP protocol.
The problem with send() function is that first it verifies whether the host IP is
multicast or not. Now my local area network is of broadcast type. So i am having …

I have software, the software should communicate with gprs devices. So i want to write a protocol, TCP, UDP communication code.
Can any one give some idea for writing a source code and some sample code also.
I'm doing an educational project in which 1) I record voice commands on a separate device and after appropriate processing etc... 2) I send 16-bit samples encapsulated in UDP packets over Ethernet to the PC.
After receiving the packets and "extracting" data (samples) from them, I need to assemble the samples to a WAV…

Can one use recvmsg() to obtain the IP_TOS field of every incoming packet or does it just show the IP_TOS value that is set for the particular socket. If not, does anyone know of a solution to obtain the IP_TOS values of every incoming packets. I am using a UDP application and therefore do not get to view the…
