Multi-tiered Virtual Local area Network (VLAN) domain mapping mechanism
A system maps network messages between a customer Virtual Local Area Network (VLAN) domain and a provider VLAN domain. Specifically, one or more ports of an intermediate network device includes frame mapping logic and may further include a plurality of highly flexible, programmable mapping tables. In accordance with the invention, a received frame associated with a customer VLAN is mapped to a provider VLAN that is selected as a function of the frame's customer VLAN and the particular port on which the frame is received. The frame may also be mapped to a provider CoS value that is selected as a function of the frame's customer CoS value, customer VLAN and the port on which the frame is received. The provider VLAN designation and provider CoS value may be appended to the frame. Forwarding decisions within the provider domain are based, at least in part, on the frame's provider VLAN designation and provider CoS value.

Quantization-based data embedding in mapped data
ActiveUS7376242B2Reduce errorsReduce the impactUser identity/authority verificationSpeech analysisAlgorithmComputer science
Novel methods and systems for quantization based data embedding and reading in host signals, such as image, audio and video signals. To embed auxiliary data in a host signal, an embedder maps the host signal from a first domain into a mapped signal in a second domain that is robust to a class of amplitude modifications that are order preserving. The embedder performs quantization based embedding of auxiliary data into the host signal using quantization bins derived from the second domain that are robust to the amplitude modifications. The mapping improves the robustness of the data embedding method by increasing the chances that the embedded data can be recovered by an auxiliary data reader after amplitude modifications. A related embedding method projects the mapped signal unto a vector, and specifically, a pseudorandom vector. It performs quantization based embedding on the projected signal. The use of this projection provides added robustness of the embedded data to noise and other forms of distortion.
