Technical Specifications

The BCM5703CKHBP21 supports 10/100/1000 Mbps Ethernet speeds. It includes TCP/IP checksum offload, which reduces CPU overhead by performing checksum calculations in hardware. Large Send Offload (LSO) further reduces CPU utilization by segmenting large TCP packets into smaller frames. Receive Side Scaling (RSS) distributes network traffic across multiple CPU cores, improving performance on multi-core systems. Wake-on-LAN (WoL) support allows remote systems to be powered on over the network. The controller also supports virtualization technologies such as VMware NetQueue, enhancing network performance in virtualized environments.
