What Is A Network Service Level Agreement

Many SLAs meet the specifications of the Information Technology Infrastructure Library when applied to IT services. A customer service level agreement exists between the provider and an external customer. An internal SLA resides between the vendor and its internal customer, it can be a different organization, department, or location. Finally, there is a vendor SLA between the vendor and the vendor. The SLA can define parameters such as service type, data throughput, and expected performance level in terms of delay, error rate, port availability, and network availability. Response time to system and/or network repairs can also be included in the SLA, as well as financial penalties for non-compliance. Reliable network operations are essential for operators to provide their customers with service level agreements (SLAs) regarding system availability and promised quality levels. Violation of these safeguards may result in severe penalties. It is therefore highly desirable to integrate an early warning and proactive protection mechanism into the network.

This can allow network operators to know when network components begin to deteriorate and preventive measures can be taken to avoid serious disruptions [33]. SLAs can also be used internally to indicate what network users can expect from IT staff and network-related procedures. The key elements of a service level agreement are: SLAs come from network service providers, but are now widely used in a number of IT-related areas. Industries that have implemented SLAs include IT service providers and managed service providers, as well as cloud and Internet service providers. The wired network consists of an IP/Ethernet service that uses a high-bandwidth multi-10 Gb backbone to provide customers with 100 Mbps, 10 Gbps, 10 Gbps wired Ethernet service on a common two-way broadband infrastructure. The types of SLA metrics required depend on the services you provide. Many elements can be monitored as part of an SLA, but the scheme should be as simple as possible to avoid confusion and excessive costs on both sides. When choosing metrics, review your operations and decide what is most important. The more complex the monitoring system (and the repair system associated with it), the less likely it is to be effective because no one has the time to properly analyze the data. When in doubt, opt for a simple collection of metric data.

Automated systems are best because expensive manual collection of measurements is unlikely to be reliable. Figure 21.31. (A) Types of defects typically encountered in commercial fiber optic networks. (B) Comparison of defect detection rates and proactive response times of data-based methods and conditions for the types of defects MENTIONED in point A ) [73] This section should describe the process by which actual service levels are monitored and compared to agreed service levels, as well as the frequency of monitoring. A brief description of the data collection and extrapolation processes should be included and how users should report problems to IT. Contract Overview – This first section defines the basis of the agreement, including the parties involved, the start date and a general introduction of the services provided. DELAY delay measures describe the time it takes to transport data from one end of the network to the other. Measuring delay involves three interrelated elements: access line speed, frame size, and wide area network (WAN) delay. .
