Abstract
Using one set of processors for downloading (and associated processing of) signature data corresponding to security application, and using another set of processors for forwarding/switching. The associated processing may include decompression of the data, authentication (hash computation and verification). Due to the use of separate processors for signature downloads, the forwarding throughput performance of a switching device (e.g., gateway/router) may not be impeded at least substantially during signature data download. Similarly, an out-of-band connection can also optionally be used for signature download.
