TCP/IP communication is currently restricted to a single path per
connection, yet multiple paths often exist between peers. The
simultaneous use of these multiple paths for a TCP/IP session would
improve resource usage within the network and, thus, improve user
experience through higher throughput and improved resilience to
network failure.
Multipath TCP provides the ability to simultaneously use multiple
paths between peers. This document presents a set of extensions to
traditional TCP to support multipath operation. The protocol offers
the same type of service to applications as TCP (i.e., reliable
bytestream), and it provides the components necessary to establish
and use multiple TCP flows across potentially disjoint paths. This
document defines an Experimental Protocol for the Internet
community.
This document is a product of the Multipath TCP Working Group of the IETF.
EXPERIMENTAL: This memo defines an Experimental Protocol for the
