METHOD FOR NETWORK COMMUNICATION PAST ENCRYPTION DEVICES

摘要

This disclosure is directed to techniques for providing communication between devices in different networks wherein the communication must first pass through an encryption mechanism and the devices do not have the stand-alone capability to encrypt or decrypt the communication. According to these techniques, an adapter may determine certain fields in a data packet that remain unencrypted when the data packet passes through the encryption mechanism. The adapter may then process those fields in such a way that, when the data packets are received by a second adapter, the second adapter may read those fields and obtain information.

主权项

1. A method comprising:
processing, with a first protocol adapter positioned within a first network, a first data packet to insert a first message within a set of one or more pass-through fields of the first packet, wherein the first network is separated from a second network by a first encryption device and a second encryption device that securely communicate packets through an intermediate network in encrypted form, wherein the one or more pass-through fields are located in a portion of the first data packet that remains unencrypted when the data packet is processed by the first encryption device; sending, with the first protocol adapter, the first data packet to the first encryption device; receiving, with a second protocol adapter positioned within the intermediate network and between the first encryption device and the second encryption device, the first data packet in encrypted form; reading, with the second protocol adapter, the first message from the set of one or more pass-through fields; and performing, with the second protocol adapter and responsive to the first message, an end-to-end quality of service admission protocol.
