Service availability is a crucial foundation element of QoS. The network infrastructure must be designed to be highly available before you can successfully implement QoS. The target for High Availability is 99.999 % uptime, with only five minutes of downtime permitted per year. The transmission quality of the network is determined by the following factors: •Loss—A relative measure of the number of packets that were not received compared to the total number of packets transmitted. Loss is typically a function of availability. If the network is Highly Available, then loss during periods of non-congestion would be essentially zero. During periods of congestion, however, QoS mechanisms can determine which packets are more suitable to be selectively dropped to alleviate the congestion. •Delay—The finite amount of time it takes a packet to reach the receiving endpoint after being transmitted from the sending endpoint. In the case of voice, this is the amount of time it takes for a sound to travel from the speaker’s mouth to a listener’s ear. •Delay variation (Jitter)—The difference in the end-to-end delay between packets. For example, if one packet requires 100 ms to traverse the network from the source endpoint to the destination endpoint and the following packet requires 125 ms to make the same trip, then the delay variation is 25 ms. Each end station in a Voice over IP (VoIP) or Video over IP conversation uses a jitter buffer to smooth out changes in the arrival times of voice data packets. Although jitter buffers are dynamic and adaptive, they may not be able to compensate for instantaneous changes in arrival times of packets. This can lead to jitter buffer over-runs and under-runs, both of which result in an audible degradation of call quality. Translation: Okay in this lab, we need to implement quality of service. Let’s have a look at router 1. On router 1, enter password of cisco type show run We can see some configuration on the router but there is no quality of service configuration on the router. So as an example, on this interface, no service policy has been applied. We don’t see any class maps or we don’t see any policy maps on the router. So conf t we’re told that we need to match a voice traffic using NBAR and specifically RTP. Let’s create a class map and I’ll use the name of voice. Now you can specify match all or match any. I’m not going to do that here but notice by default, match all is used. In this example, we’ve only got a single match statement. So that won’t make any difference. So what are we going to match? In this example we want to match a protocol. The protocol that we want to match is RTP. So we want to match Real Time Protocol. By doing that we are leveraging Network Based Application Recognition or NBARr on the router. We now need to match HTTP traffic using NBAR and we’re going to set the DSCP to AF 31. Let’s create another class map. In this case I’m going to match HTTP and again I’m going to say match protocol http Next step is to match ICMP traffic using NBAR. So class-map icmp You could use any names here but I’m simply going to match based on the protocol. So I’m going to make the class the same as the protocol. So as an example, I’ve created an HTTP class that’s matching HTTP. I’ve created an ICMP class that’s matching ICMP that have used the word voice to match RTP. You could use any descriptive name that you like for your class map. Okay so once we’ve created our class maps, the next thing we need to do is create a policy map and you need to give it a name. I’m going to call this mark. In the exam, follow the names that you’re told to use. But here we can use really any name that we want to. We then we need to match a class that exists. So we can’t just specify something like test. The class map test doesn’t exist. We need to specify a class that we’ve created such as voice and then we need to decide what to do with a voice traffic that’s matched. We’re told to set the DSCP to EF. So set ip dscp and notice here’s a list of DSCP values. This is very nice because we can see both the name as well as the binary representation of DSCP value.

Understanding Quality of Service Concept help you visualize how QoS used to prioritize Network Applications. Prioritizing certain traffic for delivery using Quality of Service, and how would you do this using UDP ports instead of TCP, will be discussed in details.
Start learning cybersecurity with CBT Nuggets. 🤍 In this video, Jeremy Cioara covers the Quality of Service (QoS) tools at your disposal in network environments. Many of these mechanisms perform similar functions but use different methods. Understanding the effect each tool is designed to have will allow you to know when to leverage the most appropriate approach in a given situation. QoS tools often have the same goals but approach a situation in various ways. This begins with classification, identifying different traffic types so a sysadmin can properly prioritize them. Marking is an optional phase of QoS, but can be an incredibly useful systematic approach that simplifies long-term network maintenance. Policing throttles down traffic, which is most often applied when you need to limit or eliminate peer-to-peer sharing. This is the only “anti-QoS” tool in our inventory. Shaping, on the other hand, is a much friendlier approach directed at traffic that needs to be managed instead of mitigated. Congestion avoidance is an efficient way to manage potential bandwidth overload. Arguably the most powerful QoS tool is queueing, which prioritizes packets based on predetermined protocols. 🌐 Download the Free Ultimate Networking Cert Guide: 🤍 ⬇️ 13-Week Study Plan: CCNA (200-301): 🤍 Start learning with CBT Nuggets: • Penetration Testing with Linux Tools | 🤍 • Intro to Networking | 🤍
🤍 Instructor Keith Edwards provides an in-depth exploration of the different aspects of queuing when it comes to network traffic congestion management. He will show you how queuing techniques are used with Cisco devices. Learn how class maps help identify types of network traffic, policy maps help identify how to treat traffic with QoS (Quality of Service) tools, and service policy command settings may be applied to one or more interfaces. He explains several different types of queuing techniques for Cisco devices including weighted-fair queuing, round robin queuing, priority queuing, and low-latency queuing.

Translation: In this packet tracer lab, you need to configure Quality of Service or QoS In this lab we’re going to cover quality of service topics such as matching traffic, marking traffic, doing something with the traffic such as providing a minimum bandwidth guarantee. Now in the real world, you would follow a quality of service policy document. In other words, you would decide which traffic types are important in your network and then allocate bandwidth accordingly or implement quality of service mechanisms such as policing, shaping, queuing and others based on your quality service policy document. In this lab, we’re going to implement a basic quality of service policy. So that you can get familiar with class maps, policy maps, service policies and other commands used for quality of service in CISCO environments. On router 1, you’re going to match traffic using NBAR or Network Based Application Recognition and then you’re going to mark the traffic with DSCP values or Differentiated Services Code Point values. In addition you’re going to use queuing on the egress interface. In other words on serial a 0/1/0 to prioritize voice traffic over other traffic types. Voice traffic will be in a priority queue HTTP and ICMP traffic will be given a minimum bandwidth guarantee. You need to do configuration on both router 1 and router 2. On router 1, you firstly need to match traffic. You need to match a voice traffic using NBAR and specifically RTP traffic or Real Time Protocol. You need to set the DSCP to EF for matched packets. So you’re going to match a voice traffic using NBAR and then mark the packets using DSCP and to set the marking to Expedited Forwarding or EF. You need to match HTTP traffic using NBAR and set the DSCP to AF 31 or shared forwarding class AF 31. ICMP traffic should be matched using NBAR and you need to set the DSCP to AF 11.......

Free CCNA Routing | Part 7 - Introduction to QoS Welcome to the Free CCNA Training Course. This series is for anyone who wants to build on their basic network skills, and even pass the CCNA 200-301 exam. Section 2 of this series covers Layer-3/Routing. This covers topics like general routing, routing protocols, OSPF, and QoS (Quality of Service). The website has additional links for further study to take you to the next level. Links are at the end of the description. In this video, we’re going to cover: 0:00 Overview 0:37 What is QoS? 3:48 Application Traffic 7:21 Classification and Marking 15:14 Cisco’s MQC 22:48 MQC - Markings QoS (Quality of Service) is a set of tools that help us to tune the network. If there’s congestion on the network, QoS can prioritize important traffic (such as voice and video) over unimportant traffic. It can also be used for rate-limiting (shaping or policing). Real-time traffic needs to be delivered steadily and on time. Other traffic types, like HTTP, are not as concerned with steady delivery. There are four traffic characteristics that we need to be aware of: Bandwidth - The amount of traffic to transfer, in bits per second Loss - The amount of traffic that doesn’t make it to its destination Latency - The time it takes to get traffic from one endpoint to another (similar to RTT) Jitter - The variance in latency Each device makes its own QoS decisions. This is called Per Hop Behaviour (PHB). Even so, all devices must work together to reach a common goal. One way they can make it easier on each other is to mark packets. This makes it easier for other devices to classify traffic and decide how to handle it. In a modern network, marking happens in the DSCP (DiffServ) field within the IP header, or in the CoS field in the Ethernet header. Older networks will use the ToS header in the IP header. QoS is configured on a Cisco router using their Modular QoS CLI (MQC). This is just the configuration hierarchy that the configuration is organised into. Interesting traffic is identified in a class-map. This may use an access-list or NBAR to help identify traffic. Then policy-maps apply actions to the traffic in these classes. And finally, a service-policy applies the policy-map to an interface, in an in or out direction.

Dans cette vidéo, nous allons explorer ce qu'est la qualité de service (QoS) et pourquoi vous voudrez peut-être l'implémenter sur vos réseaux Cisco. La qualité de service (QoS) est un mécanisme utilisé dans les réseaux informatiques pour gérer les différents types de trafic et assurer que chaque type de trafic obtient le niveau de service approprié. Cela peut inclure des fonctionnalités telles que la priorisation du trafic, la réservation de bande passante et la gestion des congestions pour éviter que certains types de trafic ne nuisent à la performance du réseau. Il existe plusieurs raisons pour lesquelles la QoS peut être importante dans un réseau informatique. Tout d'abord, elle peut être utilisée pour assurer que les applications critiques, telles que les appels téléphoniques ou les transactions financières, obtiennent suffisamment de bande passante pour fonctionner de manière fiable. En outre, elle peut être utilisée pour gérer les congestions de trafic et éviter que le réseau ne soit saturé. Enfin, la QoS peut être utilisée pour répartir équitablement les ressources du réseau entre différents utilisateurs et applications.

Download a free trial of LiveAction: 🤍 Take LiveAction for a Test Drive: 🤍 Quality of Service (QoS) is a suite of technologies used to manage bandwidth usage as data crosses computer networks. Its most common use is for protection of real-time and high priority data applications. QoS technologies, or tools, each have specific rolls used in conjunction with one another to build end-to-end network QoS policies. This video describes the first steps in the QoS process: - the three common classification methods involved - marking and differentiation process - best practices involved surrounding DSCP marking values - how hardware-based QoS marking works - Cisco QoS capabilities syntax
