Abstract
A packet data flow processor applies a first level of Data Over Cable Service Interface Specification (DOCSIS) processing to packet flows that are not from trusted sources, and applies a second level of DOCSIS processing, simpler than the first level, to packet flows from the trusted sources.
Claims20
A packet data flow processor comprising:
- logic to apply a first level of Data Over Cable Service Interface Specification (DOCSIS) processing to packet flows that are not from trusted sources;
- and
- logic to apply a second level of DOCSIS processing, simpler than the first level, to packet flows from the trusted sources.
A packet data flow processing method, comprising:
- determining if a packet data flow is from a trusted source;
- activating logic to perform a first level of Data Over Cable Service Interface Specification (DOCSIS) processing on the packet data flow if it is not from a trusted source;
- and
- activating logic to perform a second level of DOCSIS processing on the packet data flow, the second level of processing simpler than the first level, if the packet from is from a trusted source.
