comparison of Juniper JUNOS vs. Cisco IOS

Take a look at the JUNOS operating system, which is what really differentiates Juniper Networks from Cisco’s IOS.

Here, we summarize the reasons why some technical engineers chose JUNOS for our own network.

Modular vs Monolithic OS: JUNOS is a true modular operating system. Each JUNOS process runs on its own protected memory, so if a daemon encounters a problem, it can be re-started independently. When these types of events occur in monolithic OS environments, the outcome is usually a full system crash.

Single Train Software: JUNOS single train software runs all Juniper routing, switching and security products. With a single cohesive operating system, Juniper releases quarterly updates, making updates a planned event. Compare that to what people are saying about managing Cisco’s IOS versions!

OPEX Summary:

1. With a single release train, education costs and new feature implementation times are significantly reduced.
2. The stability of the JUNOS platform dramatically reduces down time.
3. The logical design and consistency of the JUNOS CLI reduces configuration time.
4. Configuration change mechanism s are designed to “human proof” the network from disasters.
5. Administrators can safely make configuration or policy changes remotely, without worrying about losing connectivity.

A recent study conducted by Lake Partners Strategy Consultants concluded organizations experienced the following time savings in the following categories:

• Troubleshooting 54%
• Upgrades and Planned Events 23%
• Duration of Unplanned Events 30%
• Frequency of Unplanned Events 24%

So, in a side by side comparison between Cisco’s IOS and Juniper’s JUNOS, it was no contest. This is the reason most of the technical team prefers Juniper.
