Cisco ISR G2 WAN speed with Services

[iskoy.istem]

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.

What does this specs mean? Does this mean that the maximum bandwidth (WAN/Internet speed) it could cater would be just up to 75 Mbps? Thanks! I'm confused...

Hi Joseph,

    You can check the ISR G2 performance from the document I provided. It would be the highest performance that the router can do without services. Just test forwarding.  As per your question Cisco 2900 series can support up to 75 Mbps (Forwarding-Rate) with concurrent services such as routing protocol, NAT etc.

Appreciate the quick reply. Thank you for the document. So 75 Mbps is the maximum transfer bandwidth from port to port with all services activated?>

Hi Joseph,

    The document doesn't specific that it can do with all services. We sometime don't know where the magic number is. In this case there are many models in Cisco 2900 series. You might get the different results when testing between models because of hardware performance. Cisco says that you might get up to 75 Mbps forwarding rate when enabling services concurrently.

HTH,

All manufacturers "fudge" their claim.  As a rule-of-thumb, get the total WAN speed value and divide it by 4.  This will tell you the "real world" speed in half duplex (you divide by 2) and encryption (you divide this by 2 again).

Hope this works.
