The race is on for leadership in network management.

Political fortunes can rise and fall

< quickly in these volatile weeks

of the Presidential primary campaign. The same dynamism is apparent in the race for leadership in enterprise network management. Last year, Sun Microsystems had the < undisputed lead with the SunNet Manager from its SunConnect subsidiary. Then Hewlett-Packard gained the edge when IBM endorsed its OpenView technology and key portions of the architecture were selected by the Open Software Foundation for its Distributed Management Environment (DME). Now Novell appears to have leapfrogged < into the top spot with its NetWare Management Systems (NMS). Designed for Windows and OS/2 environments, NMS lets network administrators manage NetWare LANs and attached devices throughout an enterprise from a single console. Sun and HP offer their network management

< hardware and software for other vendors to use as platforms for their own management applications. Accordingly, Novell could have built on HP's OpenView or SunNet Manager which employ a dedicated Unix-based console. Instead, it decided to create its own management system, using the Windows and OS/2 environments more familiar to its NetWare customers.

Sun is believed to still have the largest

< installed base with its SunNet Manager, which is primarily being used for LAN management. However, HP now has over 80 vendors developing applications for products on its OpenView platform, which is suitable for managing both LANs and wide area networks. IBM also licensed the OpenView technology

< for its new workstation-based network management system, AIX NetView/6000. The system runs under AIX on a RISC System/6000 and can manage any device attached to a TCP/IP #transmission control protocol internet protocol] using SNMP (simple network management protocol). NetView/6000 incorporates the

< graphical user interface and dynamic mapping from OpenView to handle fault, performance and configuration management. It can either run stand-alone or pass information to IBM's mainframe-based NetView through the AIX Service Point product. In addition, through its Vendor Enablement Program, IBM is working with a number of networking firms to ensure that their devices can be managed by NetView/6000. Novell's NMS has also attracted the

< support of over 60 third-party vendors who plan to use it as a base for managing their products. Also, under NetWare 3.11, NetWare servers already support SNMP and NetView, allowing enterprise-wide network management. In addition, Novell has established alliances with IBM and HP regarding network management and has talked with SunConnect about porting NetWare to Sun workstations. NMS offers vendors two ways to

< manage their products--through a NetWare Management Agent that the vendor would develop, or by importing an SNMP agent through a utility in the socalled NetWare Management Enhanced Map. NetWare Management Agents are NetWare


Loadable Modules (NLMs) that reside in each server, collecting statistics and other data from the server and attached devices and relaying them to the management console. The agents also alert the administrator to actual or potential Software development kits allow third

< parties to create products that can "register" with the NetWare agent. Once registered, the agent will know to collect data from these products as well as the NetWare servers. Novell is also supplying an SNMP agent as an NLM to run on a server and collect data on the SNMP-based devices attached to the network. The agents are polled by the NetWare Services Manager, a management console application that runs on a personal computer using Windows or OS/2 Presentation Manager. The NSM compiles and organizes data so the administrator can centrally monitor and control all the NetWare nodes. Novell says agents will also respond to polls from other systems, including NetWare Management Map, which a NetWare Management Map, which automatically discovers all devices on the network and maps them logically, giving a graphical representation of the entire network. The Windows version of NSM also

< supports the NetWare Management Enhanced Map, which allows users to scan in or create images of their building layouts. These can then be overlayed onto the logical map, linking objects with their physical location to simplify detection and repair of any malfunctions. The Enhanced Map also contains a

< utility that can manage any SNMP device. Despite the early success of NMS, it's

< expected that OpenView and SunNet Manager will continue to evolve and challenge for the top spot on the ticket for enterprise network management systems.
