Are you preparing for the CCNP Certification BCMSN exam? If so, understanding the different QoS Service Types is essential to acing the exam. In this blog post, we’ll dive into the various QoS Service Types and explain why they are important for the BCMSN exam. We’ll look at the different types of QoS services available and how they are used in networks. Read on to learn all you need to know about QoS Service Types for the BCMSN exam.
Best Effort
Quality of Service (QoS) is an important concept for network engineers to understand when taking the BCMSN exam. In particular, QoS service types can be especially difficult to master. One of the most fundamental types of QoS is best effort, which does not guarantee any specific performance or quality of service. This type of service is often used in networks that don’t require specific performance levels, or where it isn’t possible to guarantee a certain level of service. Best effort is usually implemented in unmanaged networks where no priority or guarantees are needed.
Background
Quality of Service (QoS) is an important concept in networking. QoS is a set of service requirements that allow certain types of data traffic to be prioritized over others, ensuring that critical applications and services are delivered efficiently and reliably. QoS is especially important for networks that serve multiple users and/or applications, such as enterprise networks, where data traffic can vary greatly in type and amount. The BCMSN exam focuses on understanding the fundamentals of QoS and how it can be used to improve network performance. In this section, we will discuss the different types of QoS services available and how they can be used to maximize network performance.
Video
The most common QoS service type for voice traffic is differentiated services (DiffServ). DiffServ allows network administrators to classify traffic into specific categories based on the type of application and its requirements. This ensures that all voice traffic is given the highest priority, resulting in better call quality and improved overall user experience. Additionally, DiffServ can also be used for other applications such as video streaming and real-time gaming.
Another type of QoS service type is integrated services (IntServ). IntServ is used to provide guaranteed quality of service levels for all types of applications, including voice. It works by reserving resources in advance, thus ensuring that each application gets the appropriate amount of bandwidth and resources it needs to run optimally. IntServ is usually used in larger networks where more control over bandwidth allocation is needed.
Voice
The four primary service types used for Voice traffic are Priority Queuing, Weighted Fair Queuing, Class-Based Weighted Fair Queuing and Low Latency Queuing. Each service type provides different levels of priority for voice traffic and guarantees certain levels of quality. Priority Queuing provides the highest priority for voice traffic, followed by Weighted Fair Queuing, Class-Based Weighted Fair Queuing and finally Low Latency Queuing. The BCMSN Exam will require you to be able to configure and implement each of these service types in order to maximize the quality of Voice traffic on a network.
