CISCO VERSUS JUNIPER

It is very difficult to say YES to a Product of One OEM and No to the Product of another OEM especially in the case where in the OEM’s are of the likes of CISCO or JUNIPER. BOTH ARE EQUALLY COMPETENT AND HAVE THE MATURED LINE OF PRODUCTS.

 

 DEPLOYMENT WISE, JUNIPER IS MOST SUITABLE FOR THE CORE-LAYER OF THE NETWORK WHEREAS CISCO IS MOT INTO THE ACCESS-LAYER OF THE NETWORK.

PRODUCT LINE WISE, CISCO IS A WIDEST RANGE OF THE PRODUCT NOT ONLY IN THE FIELD OF R&S BUT ALSO IN COLLAB, WIRELES, DATACENTER, SERVICE PROVIDER, SECURITY, SDN , CLOUD , STORAGE & SERVERS ETC. FROM PIN TO PLANE, CISCO IS INTO EACH AND EVERY PRODUCT LINE OF THE NETWORK.AS COMPARE TO CISCO, JUNIPER IS MORE FOCUSSED ON R&S , SECURITY AND WIRELESS ONLY. BUT WE CAN SAY LIKE THIS.. WE ALSO NEED TO UNDERSTAND OR KNOW THE CISCO IS MORE THAN 2 DECADE OLD ORGANIZATION WHEREAS JUNIPER IS A JUST DECADE OLD…..

OPERATING SYSTEM WISE, IOS(CISCO-IOS) traditionally is a monolithic operating system, which means it runs as a single operation and all processes share the same memory space. Because of the latter feature, bugs in one operation can have an impact on or corrupt other processes. In addition, if a user wishes to add features or functions to the operating system, IOS has to be deactiviated while a completely new version with the desired features is loaded.JUNOS(JUNIPER OPERATING SYSTEM), on the other hand, was constructed as a modular operating system. The kernel is based on the open source FreeBSD operating system, and processes that run as modules on top of the kernel are segregated in exclusive, protected, memory space. Users thus can add features and functions to the version of JUNOS running on their systems without disabling the entire operating system — a characteristic known as in-service software upgrades that also enhances uptime and availability.

The goal of Cisco’s New-IOS Variant — IOS XR, IOS XE and NX-OS — is to overcome the monolithic limitations of the traditional IOS while addressing critical needs for increased uptime and availability in the service-provider core and edge, and enterprise data center, respectively. All these operating systems are modular, in that IOS services run as modules on top of a Linux-based kernel (in IOS XE and NX-OS), or as a third-party Portable-Operating-System-Interface (POSIX)-based real-time kernel (in IOS XR).

As for the processes themselves — establishing VPNs and security, assigning QoS, constructing MPLS label-switched paths, routing IP protocols, supporting multicast, and establishing IP addressing, among others — IOS and JUNOS are virtually identical. They both support industry standards specified for these tasks while going beyond the standards with proprietary techniques for their own equipment.

WE AT EIIT, IN OUR OR CCNA VERUS JNCIA PROGRAMS, INVITES GUEST FACULTIES WHO ARE FROM INDUSTRY WHICH EXPLAINS THE REAL-TIME SCENARIOS DEPLOYEMENT IN MORE PRACTICAL MANNER SO THAT CANDIDATE GOT TO KNOW HOW THEY NEED TO DEAL WITH SITUATION WHERE THEY ARE IN SUCH KIND OF ENVIRONMENT.
