Abstract: An interrupt coalescing scheme for high throughput TCP offload engine and method thereof are disclosed. An interrupt descriptor queue is used, that TCP offload engine saves TCP connection information and interrupt information in an interrupt event descriptor per interrupt. Meanwhile the software processes an interrupt by reading interrupt event descriptors asynchronously. The software may process multiple interrupt event descriptors in one interrupt context.
Abstract: High-speed networking application equipments with a layer-2 to layer-7 hardware search engine and method are with flexibility and performance improvement. The multi-layer switches/routers, network address translation (NAT) gateway, firewall/VPN router and network attached storage (NAS) may use the search engine for fast and efficient search requirement.
