Abstract: A method is disclosed for exchanging data over a TCP connection between a client node and a networking node. The TCP connection comprises a primary MPTCP subflow between a customer premises equipment, a HCPE, and a hybrid access gateway, a HAG. The method comprises, by the HCPE, converting first TCP segments to first MPTCP segments 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 second TCP segments to second MPTCP segments of the primary subflow and vice versa while preserving source and destination address information.
