The IESG has approved the following document: - 'DCCP Extensions for Multipath Operation with Multiple Addresses' (draft-ietf-tsvwg-multipath-dccp-23.txt) as Proposed Standard
This document is the product of the Transport and Services Working Group. The IESG contact persons are Gorry Fairhurst and Mike Bishop. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-tsvwg-multipath-dccp/ Technical Summary DCCP communications as defined in RFC 4340 are restricted to a single path per connection, yet multiple paths often exist between peers. The simultaneous use of available multiple paths for a DCCP session could improve resource usage within the network and, thus, improve user experience through higher throughput and improved resilience to network failures. Use cases for Multipath DCCP (MP-DCCP) are mobile devices (e.g., handsets, vehicles) and residential home gateways simultaneously connected to distinct networks as, e.g., a cellular and a Wireless Local Area (WLAN) network or a cellular and a fixed access network. Compared to existing multipath protocols such as MPTCP, MP-DCCP offers special support for latency-sensitive services with different requirements for reliability and in-order delivery. This document specifies a set of extensions to DCCP to support multipath operations. The protocol offers the same type of service to applications as DCCP and provides the components necessary to establish and use multiple DCCP flows across different paths simultaneously. Working Group Summary There was discussion about whether the requirements as represented by ATSSS from 3GPP would be addressed by this spec or by other means. It was not the responsibility of the IETF to decide on the different technologies that might be used, and there was support for progressing this specification as one alternative that could be realised. Document Quality There is one fork of the Linux tree that includes support for this extension. This was demonstrated at IETF Hackathons and the results reported to the TSVWG.
