摘要： A method for bypassing a Cable Modem Termination System (CMTS), the method includes: receiving, by a session manager, an encrypted Security Association Identifier (SAID) and an encrypted Traffic Encryption Key (TEK) that are associated with unicast transmission from the CMTS to a cable modem. The encrypted SAID and the encrypted TEK are upstream transmitted from the cable modem. Providing to an edge device, over a secured link a representation of the SAID and a representation of the TEK. Receiving by the edge device information that is associated with the SAID and should be downstream transmitted to the cable modem. Encrypting, by the edge device, the information by the TEK to provide encrypted information. Transmitting, by the edge device, the encrypted information to the cable modem while bypassing the CMTS.
