VIRTUALIZED NETWORK INTERFACE FOR LOCKDOWN AND OVERLAY OF DATA IN TRANSMITTED PACKETS

摘要

A method and a system embodying the method for data lockdown and data overlay in a packet to be transmitted, comprising providing a first and a second masks comprising one or more position(s) and a data value at each of the one or more position(s); aligning the masks with the packet; comparing the data value at each of the one or more position(s) in the first mask with the data value at the one or more aligned position(s) in the packet; optionally replacing a data value at each of the one or more position(s) in the packet with a data value at the one or more aligned position(s) in the second mask; and providing the packet for transmission if the data value at each of the one or more position(s) in the first mask and the data value at the one or more aligned position(s) in the packet agree.

1. A method for data lockdown, comprising:
providing a first mask comprising one or more position(s) and a data value at each of the one or more position(s); aligning the first mask with a packet to be transmitted; comparing the data value at each of the one or more position(s) in the first mask with the data value at the one or more aligned position(s) in the packet to be transmitted; and providing the packet for transmission if the comparing indicates that the data value at each of the one or more position(s) in the first mask and the data value at the one or more aligned position(s) in the packet to be transmitted agree.
