1) Write a java program to implement a simple File Transfer Protocol by using connectionless Socket that works as follows: At the client side, the file to be transferred is divided into units of 100 bytes (and may be less than 100 bytes for the last unit depending on the size of the file). The client transfers each unit of the file to the server and but there is no acknowledgment required from the server side. did not match with any Answers results.

Re: n.w
And for "connectionless Socket" you mean "datagram" (UDP) socket, isn't it? You need DatagramSocket/DatagramPacket from java.net package.Originally Posted by fikr
Yes, with datagram sockets you don't have any acknowledge by itself, packets can arrive, never arrive, arrive duplicated (for some networking reasons) and also, more important, arrive not in the same order as they are sent.
You must be very careful, at least (take this as a hint) put an incremental counter in each packet, so that the receiver can know the order of packets and also if some packet is lost. Otherwise a "File Transfer Protocol" in this way is totally pointless.
