Multiple Listend-Routerd Pairs

You can enable multiple listend instances using multiple Listend-Routerd pairs (MLRP).

MLRP provides the capability of using multiple NICs to capture data in a load-balanced environment. You can configure your DNCA to use MLRP with multiple NICs to improve packet capturing performance and increase scalability to meet the demands of your network traffic. MLRP takes advantage of multiple NICs by creating multiple instances of the routerd process. Each routerd process requires one CPU core to operate. Each routerd process actively routes the flow of incoming network traffic from a listend process to the reassd processes. Each listend process is paired to one routerd process and can process 1 Gigabit per second of traffic. The ability to route the network traffic to multiple reassd processes removes the need to manually segment and distribute the captured traffic to prevent queuing. Balancing the network traffic to multiple reassd processors enables the DNCA to take advantage of using multiple NICs to receive and process large amounts of network traffic.
