Hi there! I hope someone is kind enough to help me with the following query:
I've read in a book that User Datagram Protocol does not segment the data. Is this true? I find this odd because if that's the case, does UDP send all data in one big chunk? Furthermore in a previous edition of this same book by the same author, he mentions that UDP does indeed segment data. I will be most grateful if someone can clear up this confusion.
Thank you in advance.
Hi, The UDP protocol does not garantee delivery of data, with that said UDP does provide check sum. Yes it does segment data if I remember correctly the MTU is 1500bytes. UDP receives data from the application process attatches destination and source port numbers fields, add additional needed fields and passed the SEGMENT to the network layler. Have a look at the link below.
