UDP (USER DATAGRAM PROTOCOL) Connectionless, and unreliable protocol in the transport  layer Provides very few error recovery services Offering a direct way to send and receive datagrams over an  IP network Used in stream media, VoIP UDP header has 8 Bytes in size

ADVANTAGES OF UDP No Handshaking Procedure in UDP prior to data  packet transmission Therefore data can be delivered sooner Its connectionless

ADVANTAGES OF UDP (CONTINUE) Simple: no connection state Each  UDP  segment  handled  independently  of  others Small segment header No  congestion  control:  UDP  can  blast  away  as  fast as desired

Unformatted text preview: TCP (TRANSMISSION CONTROL PROTOCOL) Connection oriented, and reliable protocol in the transport layer Offers error correction due to flow control Most commonly used protocol on the Internet, such as FTP, SMTP, POP3, HTML TCP header has 20 Bytes in minimum size ADVANTAGES OF TCP The operating system does all the work. you just sit back and watch the show. Guarantees three things: that your data gets there, that it gets there in order, and that it gets there without duplication Routers may notice TCP packets and treat them specially. They can buffer and retransmit them TCP has good relative throughput on a modem or a lan DISADVANTAGES OF TCP The operating system is inefficient TCP waste bandwidth, time TCP cannot be used for broadcast or multicast transmission....
