Abstract: Methods and systems for implementing virtual processors are disclosed. For example, in an embodiment a processing apparatus configured to act as a plurality of virtual processors includes a first virtual program space that includes a first program execution memory, the first program execution memory including code to run a non-real-time operating system capable of supporting a one or more non-real-time applications, a second virtual program space that includes a second program execution memory, the second program execution memory including code to run one or more real-time processes, and a central processing unit (CPU) configured to operate in a first operating mode and a second operating mode, the CPU being configured to perform operating system and application activities using the first virtual program space for the first operating mode without using the second virtual program space and without appreciably interfering with the one or more real-time processes that are running in the second operating mode.

Abstract: A processing core includes a packet classifier, implemented in a single processing core, configured to classify incoming data packets into first data packets of a known data packet flow and into second data packets of an unknown data packet flow, a first path thread, implemented in the single processing core, configured to process ones of the first data packets at least by forwarding the first data packets to a destination that corresponds to a previously determined destination associated with the known data packet flow, and a second path thread, implemented in the single processing core, configured to process a received second data packet at least to determine a new data packet flow for the second data packet.

Abstract: A network device has a packet input unit, a checking unit, and a discovery unit. The packet input unit is configured to receive ingress packets. The checking unit is configured to determine whether identifying characteristics of received ingress packets match stored identifying characteristics of a packet flow that is stored in a memory, to perform a network action when the identifying characteristic of the received ingress packet matches the stored identifying characteristic. The discovery unit is configured to intercept an egress packet received from the control plane processor, the egress packet corresponding to the received ingress packet, to determine one or more differences in selected portions of a header portion of the received ingress packet resulting from processing at the control plane processor, and to store in the memory a new network action based on the one or more differences.
