What is DiffServ QoS model?
Differentiated services or DiffServ is a computer networking architecture that specifies a simple and scalable mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks. ... The DS field replaces the outdated IPv4 TOS field.
What is expedited forwarding?
The expedited forwarding (EF) per-hop behavior assures that any traffic class with EF's related DSCP is given highest priority and is not queued. EF provides low loss, latency, and jitter. Use the EF DSCP when assigning priority to customers or applications with a premium SLA. ...
What is IntServ and DiffServ?
Quality of Service architectures for wireless networks: IntServ and DiffServ models. ... IntServ uses the per-flow approach to provide guarantees to individual streams, while DiffServ provides aggregate assurances for a group of applications. Both these models have been designed to work for wired networks.
What is DSCP classification?
A Differentiated Services Code Point (DSCP) is a packet header value that can be used to request (for example) high priority or best effort delivery for traffic. Packets with EF codepoint values are typically guaranteed highest priority delivery. ...
