Juniper Networks Inks partnership With Aruba Networks

Juniper Networks is a technology company that belongs to the network industry and communications equipment. Recently, the company released its results for the second quarter of 2014. Spite of the good results, the company's shares a declining trend amid weak third quarter guidance. This development offers a decent entry point for investors to capitalize on undervalued stocks. The detailed analysis follows:

Business

Juniper offers network infrastructure products, which primarily includes routers and switches. It is also involved in the provision of network security products and services. More importantly, the company is offering products and services related to software defined networking (SDN). Its Contrail platform provides all the necessary components for network function virtualization (NFV). NFV and SDN are gaining popularity lately; it is a threat to specialized networking equipment manufacturers. Offering SDN and NFV solution is, I believe, Juniper's way of hedging against the risk posed by network virtualization technology.

Anyhow, the company generates most of its revenue from router-sales as they made-up around 50% of the total revenue in the year ended 2013. From a different classification perspective; product revenue, or PSD, was around 75% and service revenue, or SSD, was around 25% during the year ended 2013.Juniper Networks and Aruba Networks have signed a strategic agreement to deliver open, converged wired and wireless network solutions based on enhanced technologies.

The partnership includes both joint development efforts and go-to-market collaboration, with the goal of providing solutions for the toughest problems facing enterprises.As part of this effort, Juniper is enabling technology partners, like Aruba, to take advantage of Juniper's programmable silicon by making available key software elements and new programmable application programming interfaces (APIs) to enable the High-IQ enterprise - an open, smart approach to enterprise networking that allows customers to fundamentally transform the user and operator experience. This will help foster industry collaboration to accelerate innovation for customers and partners.

According to Canalys, a global technology research firm, the mobile device market is expected to reach 2.6 billion units by 2016. Efficiently and intelligently managing this influx of devices and traffic has become increasingly difficult and complex for IT departments. Additionally, the rapid adoption of business applications-such as voice-over-Wi-Fi clients - means more comprehensive orchestration is needed, requiring granular policy and performance management to ensure that key applications are secured and optimized.

Together, Juniper and Aruba are addressing these mobility market trends with product-level integration that leverages open protocols and open APIs on Juniper switches and routers, and contextual data on users, devices, applications and location available from Aruba's enterprise Wireless LAN (WLAN) products. With this integration, enterprises will be able to optimize application performance, enable mobility-centric security and policy, and reduce total cost of ownership by eliminating vendor lock-in.

Juniper Certification Exams for Routing and Switching Service Providers

In the Routing and Switching Service Provider certification path from Junos,you’ll find four levels of Juniper Networks Certification Exams available.The entry level certification prerequisite for any certification path from Juniper Networks is the Juniper Networks Certified Associate Junos (JNCIA-Junos).The associated exam for this credential is the JN0-101,and should be completed as an essential first step before pursuing any of the other Routing and Switching Service Provider certification exams from Juniper Networks.The professional skill validation exams offered in this career focus include exams at the specialist,Professional,and Expert Levels.Exams are as follows:

  • JN0-360 – Juniper Networks Certified Internet Specialist (JNCIS-SP)
  • JN0-660 – Juniper Networks Certified Internet Professional (JNCIP-SP)
  • JPR-960 – Juniper Networks Certified Internet Expert (JNCIE-SP)
While there are some similarities between the service provider exams in the routing and switching focus and the enterprise specialist exams in the same discipline,these two different Junos certification paths should not be confused.Enterprise exams focus on the professionals competencies required of internet professionals working for businesses, designing and implementing large scale networks for corporate or other big clients.
The Routing and Switching Service Provider exams,on the other hand, are designed specifically to validate the skills and expertise of professionals working with individual clients or in the smaller enterprise environments.Rather than documenting big picture routing and switching capabilities,these exams focus on the fundamental knowledge and required skills for completing smaller,less complex,and more personalized routing and switching design and implementation projects.Whichever certification exam you take,you’ll want to ensure you’re successful in passing on the first try.The best way to prepare for professional certification testing is to utilize practice exams and self-study tutorials.
