Comparison: Cisco ISR vs ASR - So sánh Router Cisco ISR và ASR

Cisco manufactures a wide variety of Routers Cisco that are suitable for small-scale and large-scale computing environments.
Two of Cisco’s primary router lines fall under Aggregation Services Routers (ASR) and Integrated Services Routers (ISR), which are designed for distinct routing needs of different customers.
Today, we will be comparing Cisco's ASR and ISR router series, learn which options would best benefit your company. Let's dive in.





ISR Routers Models
Cisco ISR series includes:
• ISR 4000 Series
• ISR 1000 Series
• ISR 800 Series
• ISR 900 Series
• ISR 1900 Series
• ISR 2900 Series
• ISR 3900 Series
The ISR series routers are made for less computing-intensive environments, they use Cisco’s IOS operating system, as opposed to IOS XE or IOS XR, and have a small footprint in comparison to the ASR. They also have lower maximum Ethernet speeds. For example, the ISR 4000 supports up to 10 G Ethernet.

ASR Overview

The ASR series includes:
• ASR 900 Series
• ASR 1000 Series
• ASR 5000 Series
• ASR 9000 Series
Cisco created the ASR 9000 series for communications carriers and service providers as it runs on IOS XR, whereas the 900, 1000, and 5000 series run on the IOS XE system. Cisco’s IOS XR operating system is designed for Cloud-scale networking and allows for software image upgrades and module changes without impacting operations.
