MPLS VPN QoS design

In addition to the dual role of quality of service (QoS) in the private WAN and branch networks (managing packet loss and jitter), the role of QoS over the Multiprotocol Label Switching (MPLS) virtual private network (VPN) may be expanded to include the following:  Shaping traffic to contracted service rates Performing hierarchical queuing and dropping […]

Zoom, Orbit, Pan in SketchUp

In this part of the SketchUp tutorial, I’m going to show you how to rotate around the scene, pan across the scene and zoom in/out in SketchUp by using your mouse. This is a necessary skill you need to dominate in SketchUp environment because you’re going to work in a virtual 3D space. When you […]

Designing QoS for Campus networks

The primary role of quality of service (QoS) in rich-media campus networks is not to control latency or jitter (as it is in the wide-area network [WAN] or virtual private network [VPN]), but to manage packet loss. In today’s campus networks, endpoints are connecting to the network at Gigabit Ethernet (GE) speeds, and it takes […]

Bandwidth Reservation with RSVP

The quality of service (QoS) tools including marking, policing, and shaping mechanisms, have primarily been differentiated services (DiffServ) tools. DiffServ mechanisms provide bandwidth guarantees (at various levels of rigidity), but none of them provides bandwidth reservations. Guaranteed implies that the bandwidth is there when needed, but it is not set aside (or reserved) for a specific application or flow. […]

Congestion Management and Avoidance with QoS

Congestion management tools, including queuing tools, apply to interfaces that may experience congestion. Whenever packets enter a device faster than they can exit, the potential for congestion exists and queuing mechanisms apply. It is important to note that queuing tools are activated only when congestion exists. In the absence of congestion, packets are sent as […]

policing algorithms in QoS

There are different variations of policing algorithms, including the following: Single-rate two-color Single-rate three-color Dual-rate three-color This article analyzes each of the above algorithms in detail. If you are not familiar with the concept of QoS policy read “QoS Policing and Shaping” article. Single-Rate Two-Color Policers The original policers implemented use a single-rate, two-color model […]

Preferences and Tray Panel in SketchUp

In this part of SketchUp tutorial series, I’m going to talk about two places in SketchUp that you need to know about, before even starting to draw anything. The first one is the “Preferences” window which contains some of settings for the SketchUp program and then, the “Trays” which holds the most important dialog boxes […]

QoS Classification and Marking

The first step in implementing a quality of service (QoS) policy is to analyze and identify the traffic that is to be treated by some set of actions. Once determined, the packets belonging to the traffic class are usually marked by writing a value into a header field so that the traffic classification analysis happens […]

QoS Tools and Packet Headers

A fair amount of literature exists on QoS concepts, technologies, and features. Therefore, the purpose of this article is not to reiterate in depth how each of these tools work, but to provide a quick overview of the key tools available and to show how these tools interact with each other. This section will walk […]
