ISR吞吐性能问题
作者：互联网
ISR大致可以分几类：
Cisco 860、880、890
ISR1800 (fixed)、1800 (modular)、2800、3800 Series
ISR1900、2900、3800、3900 Series
ISR4K
每一代的设备，设备的性能肯定都不一样，本摘要，将主要记录ISR的吞吐性能问题。
1、下图主要体现的是800 Series和1900、2900、3900 Series，常见建议的WAN最大throughput：
该参数，基本也可以从Datasheet中查询得到，如1900和2900：

|
High performance with integrated services |
● The Cisco 1900 Series enables deployment in high-speed WAN environments with concurrent services enabled up to 15 Mbps. |
Table 1. Key Features and Benefits of the Cisco 1941 Integrated Services Router Series
|
High Performance with Integrated Services |
● The Cisco 1900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 25 Mbps. ● Multi-Gigabit Fabric enables high bandwidth module to module communication without compromising routing performance. |
Table 1. Key Business Benefits of the Cisco 2900 Series Integrated Services Routers
|
High Performance with Integrated Services |
● The Cisco 2900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 75 Mbps. ● A MultigiGabit Fabric (MGF) enables high-bandwidth module-to-module communication without compromising routing performance. |
2、下图主要针对ISR4K的WAN throughput：
Datasheet中也有记录：
