A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the TCP Maintenance and Minor Extensions WG of the IETF. Title : Datacenter TCP (DCTCP): TCP Congestion Control for Datacenters Authors : Stephen Bensley Dave Thaler Praveen Balasubramanian Lars Eggert Glenn Judd Filename : draft-ietf-tcpm-dctcp-10.txt Pages : 16 Date : 2017-08-28 Abstract: This informational memo describes Datacenter TCP (DCTCP), a TCP congestion control scheme for datacenter traffic. DCTCP extends the Explicit Congestion Notification (ECN) processing to estimate the fraction of bytes that encounter congestion, rather than simply detecting that some congestion has occurred. DCTCP then scales the TCP congestion window based on this estimate. This method achieves high burst tolerance, low latency, and high throughput with shallow- buffered switches. This memo also discusses deployment issues related to the coexistence of DCTCP and conventional TCP, the lack of a negotiating mechanism between sender and receiver, and presents some possible mitigations. This memo documents DCTCP as currently implemented by several major operating systems. DCTCP as described in this draft is applicable to deployments in controlled environments like datacenters but it must not be deployed over the public Internet without additional measures.
