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. […]
