Embodiment Construction

[0025] The operation and features of some preferred embodiments embodying the present invention are described below, and those skilled in the art will understand that the scope of the present invention is defined by the claims rather than by the description herein.

[0026] Referring now to these drawings, in particular figure 1 , depicts a block diagram of a data processing system in accordance with a preferred embodiment of the present invention. Data processing system 100 may be, for example, a desktop personal computer available from International Business Machines Corporation of Armonk, New York. Data processing system 100 includes processors 101 and 102 , which in the illustrative embodiment are each coupled to level two (L2) caches 103 and 104 , respectively, which are in turn coupled to system bus 106 .

[0027] Also connected to system bus 106 is system memory 108 and primary host bridge (PHB) 122 . PHB 122 connects the I / O bus to system bus 106, forwarding and / or s...

Abstract

A system and method for providing network communications between personal computer systems using USB communications. The disclosed USB networking hub allows multiple hosts to exist in a USB-based network. The networking hub includes an integrated virtual network adapter, which provided for communications among and between multiple hosts.

Description

field of invention [0001] This invention relates generally to computer system networks, and more particularly to networked personal computer systems. Still more specifically, the present application relates to computer networks using Universal Serial Bus based communications. Background technique [0002] Computer networking is, and has been, commonplace in industry for many years. The ability to connect many computer systems in a network, whether server / client or peer-to-peer, has become an indispensable tool in business and, more recently, has begun to enter users' homes. In order for computer networks to be available to as many people as possible, it is desirable to make setting up and operating a network as simple as possible. [0003] Current network equipment typically includes a network interface card (NIC), which is installed on each computer system and then connected to other computer systems. Even installing a NIC is out of the reach of most computer users, as i...
