Utility
Network device supporting multiple operating systems to enable optimized use of network device hardware
19 Jul 22
A method for managing a network device that includes a network operating system (NOS) and a third-party network operating system (3PNOS) includes detecting a 3PNOS state change in a 3PNOS database managed by the 3PNOS, translating the 3PNOS state change into a network device state change, storing the network device state change in a state database managed by the NOS, in response to the storing: detecting a change in the state database by a NOS agent executing in the NOS, initiating, in response to detecting the change in the state database, an update to hardware on the network device by the NOS, wherein the 3PNOS does not directly manage the hardware.

Utility
Multi-result lookups
21 Jun 22
A method for network hardware table management includes: obtaining, by a network device table manager of a network device, a first feature table entry of a first feature table, where the first feature table entry comprises a first prefix and a first action to take for a first feature; obtaining, by the network device table manager, a second feature table entry of a second feature table, where the second feature table entry comprises a second prefix and a second action to take for a second feature; making a first determination that the first prefix and the second prefix include a common portion and that the common portion is an entirety of each of the first and second prefixes; and in response to the first determination, adding a combined feature table entry to a combined feature table.
