Cisco vs juniper ?

Cisco: "Depending on how may ports and what speed you need you're going to pay more for Cisco per port. That being said, I highly recommend Cisco. The feature set is outstanding, and they're rock solid from a reliability standpoint."

Juniper: "Juniper switches have higher reliability and speed which are relatively cheaper than the Cisco switches which had dominated the market over the years. Juniper specializes on their equipment, for the purposes of hyper fast and dedicated heavy weight transmissions per day."

Cisco, I mean there is no need to the question dude, it's very obvious

Best

Cisco is more famous, reliable and best known brand and one of the leading name in the industry.

Cisco because their certifications are more popular and their commands are easier

Cisco is more popular, more efficient and more desired

I never heard about juniper, so i will choose Cisco

Cisco Because Cisco offers a variety of products and the wide range of tools is one of the main advantages of using Cisco. Cisco offers tools such as video conferencing, web conferencing and virtualmeeting spaces, helping businesses of all size cut costs. Multiple phone calls can be make withinthe network, which is another cost-saving factor. Various solutions packages, such as CallManager, Unity, CCME and IPCC (which offer various levels of connectivity and virtual-meeting software) are networking tools that help businesses save money Cisco also uses the latest technologies and doesn’t have any ties to “legacy” technologies

I will answer with just one word (CISCO)

In the data center, the Cisco vs. Juniper argument will hinge on which company has the more compelling unified data center fabric architecture: Cisco's Unified Computing System or Juniper's single-layer Stratus

It's been an ongoing debate for much of the last 14 years -- Cisco or Juniper? Increasingly, that argument will hinge on which router manufacturer has the more compelling unified data center fabric architecture: Cisco's Unified Computing System or Juniper's single-layer Stratus.

The Battle Between JUNOS and IOS

The argument began in 1996 with Juniper's founding; until then, Cisco had ruled the router roost in both the enterprise and service provider markets since its founding in 1984.

But with the growing importance of the Internet, venture capitalists and unhappy Cisco customers sunk money into the idea of forming a start-up to build a better mousetrap, specifically for service providers. Juniper's first year was nurtured with early investments from the Anschutz family (Qwest's majority stakeholder), AT&T, Ericsson, Lucent, Nortel, Siemens/Newbridge Networks, 3Com and UUNET. IBM agreed to develop custom ASICs for Juniper's Internet routers, the first of which was the M40.

With all the heavyweight backing, Juniper became and is still Cisco's most formidable challenger in service provider routing. The company gradually attained a roughly 30% share of the $8 billion market, virtually all at Cisco's expense, and has been the technological darling of some bitheads over the past decade for the purity – or purpose-built specialty – of its silicon and software.

This remains Juniper's chief differentiator from Cisco. Cisco was viewed as a packager of enterprise-class products that were being deployed in more demanding service provider requirements. Cisco's dominance and ubiquity in routing made many of its customers hungry for an alternative.

Cisco isn't standing still. It's been re-energized by the emergence of Juniper and the recent gains of Alcatel-Lucent in service provider edge routing. In 2009, Alcatel-Lucent leapfrogged Juniper's nine-year hold on the No. 2 market share position in the service provider edge, according to Dell'Oro Group.

And Cisco still holds the lion's share of the enterprise and service provider router market, with a customer base that's mostly loyal to its incumbency. But it is Cisco and Juniper that try to leapfrog each other technologically in the service provider core and edge. Right now, the multi-chassis core race pits Cisco's Carrier Routing System against Juniper's T Series for tens – even hundreds -- of terabits supremacy.

Juniper is taking the battle to enterprise data centers and cloud computing environments. Emboldened by its success in carrier routing, Juniper unveiled enterprise Ethernet switches two years ago in an attempt to become a credible alternative to Cisco's dominance in that market, too. The company believes it can carve a niche in the elite networking arenas of financial trading, high-performance computing and other demanding enterprise environments just like it did in service provider routing.

In the data center, both companies are surrounding themselves with high-profile partners to help push their competing visions: Cisco with EMC and VMware, and Juniper with IBM. At stake, just as in service provider routing, is a multibillion dollar opportunity – $85 billion in private clouds by 2015, according to Cisco – to become the primary supplier of next-generation data centers, further entrench new and existing customers, and lock its rival out of lucrative, big ticket accounts.

Yes, I agree with the guys - Cisco
