SRAM-Based Network Search Engine Features Up to 8 Million Flow Entries

The Questflo 98TX1100 from Marvell is a static random access memory (SRAM)-based network search engine that can flexibly manage, deliver, and secure up to 8 million service and virtualized flows. With deterministic throughput and latency regardless of bandwidth, packet size, and search lengths, the products support next-generation flow-based services for mobile devices and the Internet of Things (IoT). They are typically used with a network packet processor that features standard high-speed Interlaken (ILK-LA) interfaces, Ethernet packet processors, or a customized ASIC or FPGA-based solution to scale the level of service processing.

They also feature 2.4 searches per second, deterministic throughput of 1 clock cycle per search and fixed low latency from 80b to 640b keys, and multi-port configuration for device and resource sharing. Typical applications include carrier and enterprise service/edge routers, security appliances, network probes, data center switches, servers, load-balancers, and software defined network (SDN) and network functions virtualization (NFV) platforms.
