As DiffServ model is much more scalable than IntServ, it works much better in big network deployments. IntServ works well on small domains, where the number of flows and the size of the network is controlled. The reason about the improvement in scalability is given by the fact that Diffserv nodes can process traffic more easily than IntServ ...

DiffServ es un modelo de Servicio QoS Distribuido. La reserva y asignación de recursos se distribuye entre todos los routers del dominio DiffServ, lo que permite una mayor flexibilidad y eficiencia en el proceso de enrutamiento.

What is QoS? Network Quality Issues (Congestion & Slowest Link Rule) Delay Types Steps to create QoS QoS Models (Best Effort , IntServ (RSVP) ,DiffServ) QoS commands Classification & Marking Layer 2 Marking Layer 3 Marking Network Based Application Recognition (NBAR)

Feb 16, 2023 · Per Hop Behaviors are standardized methods for handling traffic at each hop in a DiffServ-"enabled" network. Assured Forwarding is a PHB in DiffServ that provides bandwidth assurance and class-based dropping of packets to avoid congestion.

So PHB, Per Hop behavior. The correct answer is A set of techniques for traffic shaping. The term PHB refers to how a node will treat traffic having the same Differentiated Services Code Point (DSCP) values. The DiffServ model itself does not specify how PHBs must be implemented.

Jul 20, 2023 · The EF PHB, a key ingredient of DiffServ, supplies this kind of robust service by providing low loss, low latency, low jitter, and assured bandwidth service. EF can be implemented using PQ, along with rate-limiting on the class (or BA). When implemented in a DiffServ network, EF PHB provides a virtual leased line, or premium service.

I want to share some brief notes about two protocols used for setting up the LSP in MPLS enabled core networks: LDP and RSVP. Both protocols have some important differences that should be understood to dig deeper into protection and restoration mechanisms as well …
