MULTIPATH TCP IN HYBRID ACCESS NETWORKS

摘要

A method is disclosed for exchanging data over a TCP connection (234) between a client node (100) and a networking node (103). The TCP connection comprises a primary MPTCP subflow (122) between a customer premises equipment, a HCPE (101), and a hybrid access gateway, a HAG (102). The method comprises, by the HCPE, converting (410, 413) first TCP segments (401, 406) to first MPTCP segments (402, 405) of the primary MPTCP subflow and vice versa, and using destination address information of the first TCP segments as destination address information of the first MPTCP segments, and using source address information of the first MPTCP segment as source address information of the first TCP segments. The method further comprises, by the HAG, converting (411, 412) second TCP segments (403, 404) to second MPTCP segments (402, 405) of the primary subflow and vice versa while preserving source and destination address information.
