ABSTRACT:
Safe and efficient passing of information from a forwarding-plane to a control-plane is provided. The information can be passed from a forwarding-plane process to a control-plane process without having to modify the control-plane process and without requiring the processes to pass information via shared memory. The information is encoded in the forwarding-plane process. The encoded information is passed to the operating system, wherein the operating system interprets the encoded information and reports the information to the control plane process. The present invention can be advantageously utilized in passing multicast events from a forwarding-plane process to a control-plane process. Multicast events can be passed from a forwarding-plane process to a control-plane process without having to modify the control-plane process and without requiring the processes to pass messages via shared memory.
