neutron N版qos介绍

作者：吕嘉伟

QOS的配置

使系统支持qos的配置：

1.修改neutron-server的neutron.conf配置

# vim /etc/neutron/neutron.conf

service_plugins = neutron.services.qos.qos_plugin.QoSPlugin

2.修改neutron-server的ml2_conf.ini配置

# vim /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]

extension_drivers=qos

3.修改ovs-agent配置

# vim /etc/neutron/plugins/ml2/ml2_conf.ini

[agent]

extensions=qos

4.配置policy.json使所用用户都有使用qos策略的权利（以下配置均为默认，可不配置）

# vim /etc/neutron/policy.json

"get_policy": "rule:regular_user",

"create_policy": "rule:regular_user",

"update_policy": "rule:regular_user",

"delete_policy": "rule:regular_user",

"get_policy_bandwidth_limit_rule": "rule:regular_user",

//设置带宽限制的权限，默认只有管理员能够设置、删除带宽限速

"create_policy_bandwidth_limit_rule": "rule:admin_only",

"delete_policy_bandwidth_limit_rule": "rule:admin_only",

"update_policy_bandwidth_limit_rule": "rule:admin_only",

"get_rule_type": "rule:regular_user",

//设置dscp规则的权限，默认只有管理员能设置、删除dscp限速

"get_policy_dscp_marking_rule": "rule:regular_user",

"create_dscp_marking_rule": "rule:admin_only",

"delete_dscp_marking_rule": "rule:admin_only",

"update_dscp_marking_rule": "rule:admin_only",

"get_rule_type": "rule:regular_user",

5.重启neutron-server和ovs-agent

QOS使用

针对tcp

例1 为端口创建策略及带宽限速规则

# neutron qos-policy-create bw-limiter
