A new Request for Comments is now available in online RFC libraries. RFC 6897 Title: Multipath TCP (MPTCP) Application Interface Considerations Author: M. Scharf, A. Ford Status: Informational Stream: IETF Date: March 2013 Mailbox: michael.scharf@alcatel-lucent.com, alanford@cisco.com Pages: 31 Characters: 75704 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-mptcp-api-07.txt URL: http://www.rfc-editor.org/rfc/rfc6897.txt Multipath TCP (MPTCP) adds the capability of using multiple paths to a regular TCP session. Even though it is designed to be totally backward compatible to applications, the data transport differs compared to regular TCP, and there are several additional degrees of freedom that applications may wish to exploit. This document summarizes the impact that MPTCP may have on applications, such as changes in performance. Furthermore, it discusses compatibility issues of MPTCP in combination with non-MPTCP-aware applications. Finally, the document describes a basic application interface that is a simple extension of TCP's interface for MPTCP-aware applications. This document is a product of the Multipath TCP Working Group of the IETF. INFORMATIONAL: This memo provides information for the Internet community.
