Appl. No.:

09/492265

Inventors:

Yi-Hsien Hao - Saratoga CA, US
Scott McDaniel - Villa Park CA, US
John K. Lenell - Huntington Beach CA, US
Andrew M. Naylor - Costa Mesa CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 12/28

US Classification:

370392, 370412

Abstract:

Memory structure, and packet-based switch including the memory structure, having Address Resolution Table and Packet Data Buffer table employing a shared memory. Transmit Descriptor Table also may share memory. Address Resolution Table can be implemented with direct mapping, for which destination address key direct-mapped address search may be used. The memory structure and switch implement an IEEE Std. 802. 3 communication protocol via multiple ports.

Abstract:

A network interface device for use with a host computer that includes a host processor and a memory, and which is configured to concurrently run a master operating system and at least one virtual operating system. The device includes a bus interface that communicates over a bus with the host processor and the memory, and a network interface, which is coupled to send and receive data packets carrying data over a packet network. A protocol processor is coupled between the bus interface and the network interface so as to convey the data between the network interface and the memory while performing protocol processing on the data packets under instructions from the at least one virtual operating system, while bypassing the master operating system.
