Abstract:
1. A method for inserting a middlebox in an existing network connection, comprising: monitoring network state information in a network connection between a client device and a server device; determining that the network connection between the client device and the server device is idle with a processor; creating a first connection entry at the middlebox for the client device and a second connection entry at the middlebox for the server device, where the first and second connection entries are initialized using state information gathered by said monitoring after determining that the network connection between the client device and the server device is idle; and activating redirection of the network connection between the client device and the server device after determining that the network connection between the client device and the server device is idle, such that the middlebox manages the created first connection entry and second connection entry to replace the network connection and mediate the connection between the client device and the server device.
