• ISR吞吐性能问题


    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,厂商建议的WAN最大throughput,该建议应适合大多数企业和商业客户:

    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:
