Why do we need QOS (Quality of Service) (Tagalog) | Free CCNA Tutorials for Beginners Philippines

Ang QOS (Quality of Service) ay isa sa mga topics na covered sa bagong CCNA 200-301 curriculum.

Isa yan sa mga importanteng element sa isang network na mataas ang traffic volume.

Ano ba yang QOS?

Ano yung relevance nyan sa network setup mo?

Kung naga-aral ka para sa CCNA mo, or interesado ka sa mga network techologies - itong video na ito will give you an overview sa Quality of service na yan

Love all your tutorial videos, they are very informative and easy to understand. By the way I attended your Cisco training before in QC. Kudos to the way of your teaching! 👏🏻

Been checking Youtube for some Cisco reviews, and came to this channel and I subscribed. Very good on the explanations, although medyo nabitin kasi putol, or do I have to pay to access more explanations? hehehe. Adding more to what ms Elen pointed out is the default queuing mechanism for routers is called "tail-drop" and it's applied to both the ingress/egress side on the router interface. Kapag puno na yung queue for the ingress/egress side of the interface, next packets coming in would be dropped (tail-drop). That's why we apply QoS to prevent this lalo na kung affected yung mga maliliit and delay-sensitive applications like VoIP, IP-based videos, etc. Dun na papasok yung QoS through traffic classification (UDP ba or TCP, or learning the application itself using NBAR), marking (DSCP or IP-precedence, MPLS-experimental naman if MPLS-based), traffic conditioning, policing or shaping, congestion avoidance (RED or WRED), queuing and scheduling, etc. QoS should classify traffic based on the following classifications: real-time or high priority (we put in VoIP and video here, or any other apps that we consider as delay-sensitive), mission-critical (voice-signalling, SAP or some database traffic), and best effort (internet traffic and others deemed not critical).

Hi po, Mam Elena. Ask ko lang po kung yung Cisco Wireless section po ba ng CCNA ay pwedeng magamit pag ang magiging work mo ay RF Engineer/Wireless Engineer/Telecommunications Engineer? Or talagang pang-Network Engineer/IT Professional lang po talaga yung CCNA certification? Ano pong pinagkaiba ng CCNA (Cisco Certified Network Associate) sa CWNA (Cisco Wireless Network Associate)? Saka ask ko na din po pala kung meron po kayang mga remote work/remote jobs na mahahanap sa engineering dito sa 'Pinas or sa abroad. Ang mga kalimitan ko po kasing nakikitang mga remote jobs/remote work ay Software Engineer, Technical Support Engineer at Customer Support Engineer. Salamat po.
