General Motors Corp’s Mountain View, California-based Hughes LAN Systems and Hewlett-Packard Co have announced a joint development effort to produce an integrated multi-port probe for hubs. The project will incorporate Hewlett-Packard’s LanProbe II segment monitor into Hughes’ Enterprise Hub. According to Hughes, the Enterprise Probe will simplify the management of distributed networks and reduce maintenance costs by enabling network managers to monitor and control all segments of an enterprise hub network from a centralised management station. The Enterprise Probe software will run as an application on both the Windows and Unix versions of the Hughes 20/20 software, reports Hughes. The Enterprise Probe Ethernet Module will cost $2,000, while the Token Ring Module will be priced at $3,000. An MS-DOS version of the Enterprise Probe software will cost $4,500. They will all be available in the fourth quarter, 1994. Hughes has also announced a new set of network management applications for Hewlett-Packard’s Unix-based OpenView system. The applications, which are intended to manage Hughes Enterprise Hubs and Virtual local networks, provide a graphical system for the management of enterprise networks, says the company. The Hughes 20/20 Enterprise Hub Manager for Hewlett-Packard’s OpenView Unix system will cost $6,000 and will ship in the fourth quarter, 1994. Hughes says it will continue to market its Monet SNMP-based network management system for multi-vendor, enterprise-wide networks.
