Multi-user LAN packet generator

摘要

A packet generating Ethernet testing device is provided with a microprocessor for generating packets. A packet memory is provided which stores the generated Ethernet packets. A packet forwarding device is connected to the packet memory and to the microprocessor. A MAC bus is connected to the packet forwarding device for forwarding packets to the bus and receiving packets from the bus. A plurality of media access controllers (MACs) are connected to the MAC bus for controlling an output of Ethernet packets from the packet memory. A physical layer connection is provided connected to each of the media access controllers. A media interface is connected to the physical layer. The media interface is connected to a port of a device to be tested for injecting Ethernet packets into the device to be tested. The packet generating Ethernet testing device preferably also includes another MAC bus and another plurality of media access controllers connected to the another MAC bus. A physical layer connection is provided for each of the another plurality of media access controllers. A media interface is connected to the physical layer of the another plurality of media access controllers.
