Network Management

This process aims to provide reliable networking. It does this through continuous and consistent knowledge of network availability and health. It uses automated monitoring of all network resources, automated correlation of data, automatic notification of trouble, and rapid diagnosis and resolution of network availability problems.

Tasks

Skills

Provide first-level network support using selected tool-sets

Evaluate health of network and perform level one analysis

Define the processes and procedures for network monitoring

Enforce network usage standards—bandwidth requirements

Monitor OLTP and other transactional systems from a network view

Familiarity with networking protocols and topology

Understanding of SNA and IP network protocols

Knowledge of IP and SNMP

Knowledge of network devices and relationships

Staffing

Best Practices

Metrics

Highly automated network monitoring systems in place

Integrated presentation of network status information to differing operational groups

Use of monitoring to drive automation, notification, and problem management applications

Ongoing documentation and evaluation of network topology, performance, standards, configuration, change control, faults, and accounting.

Ratio of personnel versus infrastructure elements (such as IP addresses)

Percent of events processed automatically

Network up-time (availability), component availability

Network latency, data delivery rate, throughput

Number of chronic problem groupings

Mean time to isolate a link failure, repair it, and restore service

Process Integration

Futures

Configuration management

Problem management

Better assessment of business operational impact of network problems

Consolidation all resource-centric data (event, problem, asset, change)

Directory-enabled network management (for example, directories with policy content to drive quality of service tuning of network flows)

Better discovery technology for deriving device relationships
