In this paper, we study how to provide dependable network processing through multi-core based network processors (NPs). We present the performance analysis results of an NP based network system and motivate our research. We propose to use the redundant cores available in an NP to handle faults. We outline a fault-tolerant (FT) task model specifically for NP based applications and describe our implementation...
With the explosive growth in Internet traffic, requests have been overloading Web servers. Many ISPs and search engines employ a server cluster to build a cost-effective, scalable, and reliable server system. To make such a distributed-server system transparent to clients, architects usually place a switching device with one virtual Internet protocol (VIP) address in front of the server cluster as...
Deep Packet Inspection (DPI) refers to examining both packet header and payload to look for predefined patterns, which is essential for network security, intrusion detection and content-aware switch etc. The increasing line speed and expanding pattern sets make DPI a challenging task. Network Processors (NPs) are chosen to perform DPI due to their packet processing performance and programmability...
