  • Maintaining network compatibility
    Patent number: 8165157
    Abstract: A method for improving network compatibility, the method including but not limited to the following: receiving a first-protocol data-link layer packet having a first-protocol address, the first-protocol data-link layer packet encapsulating a network-layer packet bound for a network layer entity native to a second-protocol data link layer environment, directly translating the first-protocol data-link layer packet to at least one second-protocol data-link layer packet encapsulating at least a part of the network layer packet, where the at least one second-protocol data-link layer packet has addressing including a pre-defined second protocol companion address of the first-protocol address, and transmitting the at least one second-protocol data-link layer packet into the second-protocol data-link layer environment. Hardware and/or software can effect the foregoing referenced method.
