Best Practices for Monitoring Distributed Service Provider Networks
Service providers are starting to capitalize upon the power of IT. Valuable technology like IP, SDN, NFV, IoT, and cloud networks are helping to modernize the existing infrastructure so that service providers can reduce costs and improve security. In addition, new architectures (like 4G and CORD) are available for wireless and wireline networks to help them transform as well. As the networks themselves change, network monitoring and network visibility capabilities need to change as well. A visibility architecture with network packet brokers (NPBs) can be used effectively to reduce costs, optimize user quality of experience (QOE), improve network security defenses, and support regulatory compliance initiatives.
Specifically, service providers can use NPBs to:
- Aggregate data from multiple sources (SPAN ports, taps, virtual machines)
- Lower the cost of data aggregation
- Filter out unnecessary data flooding to your security and monitoring tools to make them more efficient
- Load balance data across multiple tools to extend the life of those existing tools
- Perform packet trimming/slicing to improve network security and increase regulatory compliance
- Perform header stripping to make security and monitoring tools more efficient
- Take advantage of component automation to reduce costs and improve service efficiency
This document provides the basic information that service providers need to optimize their network visibility and monitoring architecture.
