3Com TokenLink VelocityTM XL PCI Network Interface Card manual Parallel Tasking II technology

4GLOSSARY

Parallel Tasking II technology

A proprietary PCI bus master interface developed by 3Com that builds on the earlier Parallel Tasking architecture to achieve faster data transfer rates and lower CPU utilization.

Parallel Tasking II technology removes any limits on the size of the data bursts across the PCI bus.

PCI

Peripheral Component Interconnect. The PCI 32-bit bus provides a processor-independent data path between a PC’s central processing unit (CPU) and high-speed peripheral devices. The PCI bus supports multiple peripheral components and add-in cards at a peak bandwidth of

132 MBps, which is up to 10 times faster than that of ISA, EISA, and MCA PC buses. PCI provides full Plug and Play support for automatic NIC configuration in the PC.

promiscuous mode

A method by which a NIC receives and forwards all network packets that arrive, regardless of the node to which they are addressed. This feature allows easy identification and resolution of network problems.

token ring

A network that employs a ring topology and passes tokens for ring access.
