Network QoS for vNICs
Oracle’s network Quality of Service (QoS) provides administrators the ability to treat
packets differently, based on the type of traffic. This chapter explains how to
configure a QoS policy and apply it to virtual resources. It contains the following
sections:
■ “QoS Terminology” on page 191
■ “Network QoS Services” on page 193
■ “QoS Operations Overview” on page 193
■ “QoS Feature Matrix” on page 195
■ “QoS Default Sets” on page 195
■ “QoS Custom Sets” on page 197
■ “ACLs With QoS and Application QoS” on page 202
■ “Disabling QoS on a vNIC” on page 205
■ “Application QoS With Ingress 802.1p and IP Precedence Mapping” on page 206
■ “DSCP Mapping on 10GbE Cards” on page 207
Network QoS profiles, like most objects in the Oracle Fabric Interconnect, have
“Naming Conventions” on page 8.
QoS Terminology
Requirements can be expressed in terms of committed/peak information rate,
committed/peak burst size, application flows, traffic direction, and network delay
incurred by an I/O module. QoS ensures traffic differentiation during congestion
periods. The behavior of one type of traffic should not affect the observable
characteristics of another type of traffic. A policer restricts the amount of bandwidth
to a set rate. All traffic transmitted or received above a defined threshold is dropped.
