Abstract
A networking system, and more particularly an interface management subsystem, offers logical interface abstraction for networking system software. The networking system generally transmits data via a hardware interface. All software components in the control and forwarding plane use a Logical Interface (LIF) that is a logical representation of the hardware interface. A mapping occurs between the LIF and hardware interface used to transmit the data. Each LIF is represented by an LIF identifier used to store and retrieve logical interface records to and from shared memory accessible to all protocols and applications in the control and forwarding plane. The efficient storage and retrieval of such logical interface records allows for a global unique view of network interfaces, avoidance of data replication in each networking system software application's memory space, etc.
