TMPP for Both Two MPTCP-unaware Hosts
draft-xue-mptcp-tmpp-unware-hosts-01
Abstract
Transparent MPTCP Proxy(TMPP) is an introduced network-based
function, which is under MPTCP architecture. It can help two MPTCP-
unaware hosts enjoy multipath support, and can be extensively used
both in the access networks and operators' networks. Meanwhile, in
MPTCP architecture with TMPP, TMPP needs to modify the received
packets and transmit them again(just like gateway in NAT
environment). In this document, we also discuss the guarantee for
data transfer on TMPP's side. The consideration of data transfer can
be expanded to the MPTCP architecture with proxy.
