Abstract:
1. A method of providing data from a first network to a second network, the method comprising: receiving, by a gateway node, a first packet from the first network; determining, by the gateway node, whether the first packet includes state information; converting, by the gateway node, TCP protocol transport layer information of the first packet into User Datagram Protocol (UDP) transport layer information if the first packet includes TCP protocol-specific state information; generating, by the gateway node, a control message including context information regarding the conversion of TCP protocol transport layer information into UDP transport layer information if the first packet includes TCP protocol-specific state information; transmitting, by the gateway node to the first network, a TCP protocol-specific state-related response in response to receipt of the first packet if the first packet includes TCP protocol-specific state information which requires a TCP protocol-specific state-related response; transmitting, by the gateway node to the second network, the converted first packet to the second network if the first packet includes TCP protocol-specific state information, wherein the transmitting occurs subsequent to the transmitting of the TCP protocol-specific state-related response if the first packet includes TCP protocol-specific state information which requires a TCP protocol-specific state-related response; transmitting, by the gateway node to the second network, the generated control message including context information regarding the conversion of TCP protocol transport layer information into UDP transport layer information if the first packet includes TCP protocol-specific state information; and transmitting, by the gateway node to the second network, the first packet if the first packet does not include TCP protocol-specific state information.
