A system and method for data stream processing. Two or more instances are connected as a topology, wherein at least one of the instances is a spout and at least one of the instances is a bolt. The topology is submitted to a scheduler, wherein the service scheduler receives resource offers from a cluster manager representing computing resources available on one or more of cluster nodes and determines resources to accept and computations to run on the accepted computing resources. The topology is scheduled as one or more jobs, wherein each job includes two or more containers, including a first container and a second container, the first container including a topology master and the second container including a stream manager and one or more stream processing system (SPS) instances, wherein each SPS instance represents one of the instances in the topology.

Stream processing at scale

A system and method uses messages and traps to identify routers to selectively request information about tunnels on a network in order to maintain tunnel information about a network to minimize the impact of maintaining such information.

System and method for identifying tunnel information without frequently polling all routers for all tunnel information

A system and method collects information for VPN traffic from non edge routers that are coupled to edge routers and identifies the path the traffic took and the customer corresponding to the VPN. The system and method also identifies the ingress router coupled to the non edge router from which the traffic was collected. The system and method may assign identifiers to route targets.
