描述 Description

The StrataXGS® Trident 4 series is a family of Ethernet switches designed to address performance, capacity, and service requirements for next-generation data center and cloud computing environments as well as high-bandwidth enterprise and mobile network applications. The Trident 4 architecture delivers complete, user-programmable forwarding and instrumentation capabilities at a very high port density, while maintaining minimum power, latency and board footprint.Trident 4 has extensive features to address the rapidly increasing scale of data center network deployments and distributed computing applications. These features include flexible in-band and streaming telemetry, large scale forwarding databases with flexible allocations to allow tailoring to the required application, and support for the latest in datacenter protocols.To enable high network utilization, Trident 4 features a wide variety of load balancing and congestion management technologies including Dynamic Load Balancing, Dynamic Group Multipathing, Resilient Hashing, Latency-Based ECN marking, and Elephant Flow detection/re-prioritization.Trident 4 is programmed using the NPL high-level language.  For more information on NPL, please visit https://nplang.org/.
