Switching Devices Avoiding Degradation of Forwarding Throughput Performance When Downloading Signature Data Related to Security Applications

摘要

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.
