Claim of US Patent No. 10,602,560

1. A method performed by a first network node, the method comprising:determining a first amount of resources associated with a usage of a first Multi Path Transmission Control Protocol (MPTCP) connection between the first network node and a second network node;
determining whether the determined first amount of resources meets a first criterion;
in response to determining that the determined first amount of resources meets the first criterion, initiating a second MPTCP connection between the first network node and the second network node in addition to the first MPTCP connection;
after initiating the second MPTCP connection, using both the first and second MPTCP connection to transmit data to or receive data from the second network node;
while using both the first and second MPTCP connection to transmit data to or receive data from the second network node, determining a second amount of resources associated with a usage of the first MPTCP connection between the first network node and the second network node;
determining whether the determined second amount of resources meets a second criterion; and
in response to determining that the determined second amount of resources meets the second criterion, terminating the second MPTCP connection.
