篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ISR吞吐性能问题相关的知识,希望对你有一定的参考价值。

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

该参数,基本也可以从Datasheet中查询得到,如1900和2900:

Table 1.       Key Features and Benefits of the Cisco 1921 Integrated Services Router

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:

三种性能级别:

Platform Factory Default Performance License Boost License
4451 1Gbps 2 Gbps @ 19% CPU 4 Gbps* @ 35% CPU
4431 500Mbps 1 Gbps @ 18% CPU 4 Gbps* @ 62% CPU
4351 200Mbps 400 Mbps @ 17% CPU 2 Gbps* @ 45% CPU
4331 100Mbps 300 Mbps @ 16% CPU 2 Gbps* @ 53% CPU
4321 50Mbps 100 Mbps @ 8% CPU 2 Gbps* @ 68% CPU
4221 35Mbps 75 Mbps @ 8% CPU 1.4 Gbps @ 94% CPU

 

 Datasheet中也有记录:
