TCP Overview

• Provides reliability, error checking, ordered packets in a stream

• Congestion control built in

• Internet could not survive without it

• Works well for most internet traffic, email, web browsing small ad-hoc transfers

File Transfer Issues with TCP

• Flow control limits transmission window, causes dead air with high latency

• Very aggressive in response to network congestion, cannot tune in application layer

• Result is less than ideal performance on wireless, satellite, or long haul links

• Can be tuned but still not ideal for many-one, one-many

TCP is a very serial process. Each packet of data must be received before a new packet is sent = Decreased transfer speed

UDP File Transfer Considerations

• Plays fair with other traffic on network

• 10 Gbps file transfer, single stream

• High performance for many small files

• Security, reliability, automatic resume

• Automation tools, SDK, central management
