Ternary Content Addressable Memory (TCAM) is becoming very popular for designing high-throughput forwarding engines on most of today's high-end routers. Despite its capability for line-speed queries, it is very power hungry and capacity inefficient. Many recent research efforts, such as CoolCAMs and SmartPC, were proposed to reduce power consumption by constructing a pre-classifier to activate TCAM...
Network packet classification is an important functionality provided by modern Internet routers for enabling many network applications such as quality of service, security and differentiated services. Decision-tree based schemes are the most well-known algorithmic solutions for packet classification. But most of them, such as HiCuts and HyperCuts, suffer from memory explosion problem due to uncontrolled...
Network packet classification is a key functionality provided by modern routers enabling many new network applications such as quality of service, access control and differentiated services. Using ternary content addressable memories (TCAMs) to perform high-speed packet classification has become the de facto standard in industry. However, despite their high speed, one major drawback of TCAMs is their...
To achieve the monitoring and control function of traffic signal lights, a system using PLC with Ethernet function as its controller is developed. The local control program is based on IEC61131-3 standard language and the remote control program is based on LabVIEW. OPC Server realizes the data communication between controller and remote control program. This system with web camera installed in the...
