CCID 4 is for experimental use, and uses TFRC-SP (RFC 4828), a variant of TFRC designed for applications that send small packets. CCID 4 is considered experimental because TFRC-SP is itself experimental, and is not proposed for widespread deployment in the global Internet at this time. The goal for TFRC-SP is to achieve roughly the same bandwidth in bits per second (bps) as a TCP flow using packets of up to 1500 bytes but experiencing the same level of congestion. CCID 4 is for use for senders that send small packets and would like a TCP- friendly sending rate, possibly with Explicit Congestion Notification (ECN), while minimizing abrupt rate changes. This memo defines an Experimental Protocol for the Internet community.", "pub_date": "August 2009", "keywords": [ "ccid 4", "congestion control identifier 4" ], "obsoletes": [], "obsoleted_by": [], "updates": [], "updated_by": [ "RFC6323", "RFC8311" ], "see_also": [], "doi": "10.17487/RFC5622", "errata_url": null }
