今天过了一眼IceHouse Neutron新增加的Blueprint(https://blueprints.launchpad.net/neutron/), 先一睹今后Neutron的样子。我将看起来重要一点的blueprint前面加[*]了, 包括重要的特性，以及对于工程师来说必须关注的代码重构。

1，[*]为运行在同一个host上的vm或port灵活的分配带宽，https://blueprints.launchpad.net/neutron/+spec/support-rate-limiting
2, 为neutron client指定http timeout, https://blueprints.launchpad.net/neutron/+spec/specify-neutronclient-timeout
3, 支持定义哪些外部external networks可以被哪些tenant所共享，https://blueprints.launchpad.net/neutron/+spec/sharing-model-for-external-networks
4, 允许为Security Group定义差分服务点DSCP(Differentiated Services Code Point，即利用IP头部的TOS字段实现服务优先级别),
举个例子：针对tcp协议目的端口是22的数据包打上dscp标签0x2A: iptables -A POSTROUTING -t mangle -p tcp –dport 22 -j DSCP –set-dscp 0x2A
