Comet SoftwareComet VIAThe VIA, proposed by Compaq, Intel and Microsoft, introduces anew network API that defines each user process a protected, directly accessible Virtual Interface (VI) to network hardware. Though VIA is originally proposed for System Area Networks and it does not care about IP, the core idea is also useful in the IP processing, because it eliminates the OS overhead and makes a network adapter closer to each user process. Furthermore, IP processing in the Comet network adapter enables any protocols to be carried on the Gigabit Internet, the most widely used commodity network, without a penalty of packet encapsulation overhead.
Current SoftwareMany applications can be used under various OS which operatesComet. We made the firmware which runs on two PC/AT compatible machine and one engineering workstation. The firmware includes the drivers which operates each network interface card (NIC). PC/AT compatible machine is equipped with 200 MHz Pentium Pro and 128 MB memory running on BSD/OS with 32 bit, 33 MHz PCI bus. The workstation is equipped with 250 MHz UltraSPARC running on Solaris 2.6 with 64 bit, 66 MHz PCI bus. In handing over the data between OS and Comet, GCD (Generic Comet Driver) is driven internally in the independent form of operating systems.
