Service-oriented router (SoR) is a new router architecture for providing rich services to Internet users by utilizing useful information extracted from network traffic. In SoR, stream reconstruction and selection is a fundamental process for providing the services in the application layer. After real-time reconstruction of stream data, SoR used a software character string analyzer to extract important required information. One of the promised services is a router-level network intrusion detection system. Because a network consists of hundreds of thousands of data streams, achieving an intended throughput while analyzing these stream data is a critical problem. We propose an acceleration method of string matching based on a heterogeneous system consisting of a CPU and a graphics processing unit. In addition, we designed and implemented a task controller that improves the distribution of POSIX-thread-based processes so that string matching can be performed concurrently depending on the status of the string matching system.<\/p>\n","protected":false},"excerpt":{"rendered":"
