The Cisco Mobile Wireless Fault Mediator (MWFM) is part of the CiscoWorks2000 for Mobile Wireless bundle (See Figure 1) which is a suite of element manager software (EMS) applications that enhances the delivery of new mobile wireless services. Based on CiscoWorks2000, it addresses the element management requirements of mobile operators and provides fault, configuration, accounting, performance, and security (FCAPS) functionality as mobile operators transition their wireless service delivery networks from second-generation (2G) circuit-based traffic to 2.5G and third-generation (3G) IP-based services.
In this context, MWFM is a feature-rich device layer solution that provides alarm filtering and correlation of Cisco wireless support nodes such as the Cisco Mobile Wireless Router or the Cisco PDSNs/GGSNs and their neighboring Catalyst® switches. MWFM uses complex mathematics to solve the change-monitoring problem, allowing network-management products such as Fault Manager of Manager (MoM) to support networks that are experiencing the phenomenal growth imposed by the boom in mobile Internet traffic.

The Cisco MWFM discovery engine finds all Cisco mobile wireless nodes, such as PDSN, GGSN or MWR1900 and any Cisco Catalyst switches attached to the IP network, capturing not only what is present, but also the port-to-port connectivity between devices on the network. This information is stored in a database designed to allow rapid storage, retrieval, and updating of data concerning connectivity between devices.
Cisco MWFM consistently provides an accurate map of the network. Even as the network changes, ongoing passive discovery detects when new Cisco mobile wireless devices are added and triggers a partial rediscovery of that portion of the network.
Cisco MWFM uses a policy-based management system where all aspects of the network are controlled and administered from a single point. This approach relies on active object classes (AOCs) to monitor network elements and define polling requirements. AOCs describe how to identify devices, determine connectivity, and monitor the devices for problems.
Cisco MWFM can perform aggregated polling, which consolidates polling requests for multiple applications, thereby minimizing the unnecessary use of network and device bandwidth. To further minimize unnecessary polling, Cisco MWFM uses caching technology to store the most recent device information. Standard polling methods include ping and Simple Network Management Protocol (SNMP). Cisco MWFM monitoring also accepts SNMP traps and reads device syslog files.
For many service providers, the migration toward mobile Internet networks creates a unique management problem. Large investments in legacy systems must be leveraged while continuing the migration toward IP environments. In these mixed environments, the issue becomes how to transparently manage the mix of technologies while continuing to deliver the highest level of service availability. The flexible and open nature of Cisco MWFM provides off-the-shelf integration with popular Fault MoM, such as Cisco Info Center or HP OpenView.
Designed as an application system of CiscoWorks2000 Mobile Wireless networks, Cisco MWFM is uniquely capable of serving as the central fault monitoring component at the element management layer for Cisco GPRS, CDMA and mobile services solutions. For administrators, this means less time spent writing rules and building intelligence into the network management system and significant gains in network availability.
