Benefits of technology

This patent describes a method for protecting electronic components against damage caused by excessive current flow through certain connections. It suggests using a special type of communication called Hot Swap Protocol, which allows the ports adapter to communicate with the host computer without interrupting any data being transmitted over it. By doing this, the device's performance will improve while still maintaining its functionality.

Problems solved by technology

This patent describes a problem where conventional port adapters cannot handle specific types of protocols like SPI-4 bus without being limited to certain options. Additionally, these adapters require complex hardware configurations and processes, which makes them difficult to scale up to new standards.

Abstract

A port adapter for connecting zero or more network interfaces to a host system having a SPI-4 bus is disclosed. The port adapter comprises zero or more network interfaces; a SPI-4 bus coupled to a host system to provide a communication channel between the host and the network interfaces; a control bus coupled to the host system for controlling and monitoring the port adapter; and interface logic that interfaces the SPI-4 bus and the control bus to the network interfaces. Methods are provided for selecting and using one of a small plurality of different packet formats for various networking technologies, so that the port adapter can hide details of the technology that it handles from the host system, and for operating the host system's SPI-4 bus at one of several speeds based on bandwidth requirements of the port adapter.
