Why Use Cisco Network Systems?

Why Use Cisco Network Systems?

The Answer

Cisco has been central to many historic changes in technology and its use. Now, when the technology industry is going through a period of dramatic change, Cisco remains the market leader in multiple areas, such as routing and switching, unified communications, mobility, and security. The company helped catalyze the industry’s move toward IP, and, now that it is fully under way, Cisco is at the center of fundamental changes in the way the world communicates.
Based not only on its technical prowess, but also its financial stability, commitment to innovation, and dedication to its customers, Cisco enjoys a reputation as one of the top companies in the world.

Commitment to Innovation

Even more so than its financial history, Cisco is proud of its reputation for innovation. This reputation is caused in part by the Cisco development strategy of “build, partner, and acquire.”

• Cisco develops most of its products internally, using a deep pool of global engineering talent. With one of the largest research and development budgets of any technology firm (more than $4 billion), Cisco invests heavily to enable over 16,000 Cisco engineers working in more than 1100 labs worldwide to develop new products and technologies.

• Cisco also understands the value of partnering and has sought to include primary partners at every phase of the product and technology lifecycle, from concept through delivery.

• Having originated as a “startup,” Cisco recognizes that smaller companies often develop new and valuable technologies. To continually enhance its portfolio of leading-edge products and technologies, Cisco has acquired more than 110 carefully chosen innovative companies since its inception.

Cisco understands and addresses the unique requirements of each place in the network:

• Campus: Market factors are causing a shift in corporate structures. Reduced time to market translates to a greater need for interaction throughout a company. And as these companies become more adept and more dependent on technologies for this interaction, the network must provide a platform that enables and promotes enhanced communication and collaboration.

Cisco provides a platform designed for collaboration with the Campus Communication Fabric, which enables application proficiency, secure multimedia communications, improved productivity and innovation, business continuity, and efficient operations over a flexible infrastructure.

• Branch/WAN: Historically, branch users have not been given the same priority as users at headquarters, enduring less-than-optimal response times, receiving a subset of services, and experiencing downtimes that are not tolerated at headquarters. But this is changing. Because of the increased number of acquisitions and mergers, along with the focus on local presence and global expansion, remote office workers have gained significant importance in the equation for business success. Today’s branch users require the same consistent delivery of services and applications as headquarters users.

• Data center: The rapid proliferation of new applications combined with the increased complexity of these applications mean that IT managers require data center architectures that are more resilient, more adaptable, more manageable, and capable of serving users across geographically dispersed locations.

Cisco data center solutions are built on the principles of consolidation, virtualization, and automation to provide the security, availability, manageability, and optimized application delivery that enable superior service delivery and application performance.

Network Systems Components

When you look closer into each of these network systems, you find components that are industry leaders in their own right. Cisco provides one of the most robust, intelligent lines of integrated services routers, along with one of the most comprehensive, feature-rich portfolios of network switches.

Routing

Cisco routers allow organizations to build a foundation for an intelligent, self-defending network, featuring best-in-class security services and routing technologies for a low total cost of ownership and a high return on investment. These routers offer:

• Industry-leading services densities, bandwidth, availability, and performance options for maximum configuration flexibility and scalability for the most demanding networking environments

• Superior services performance and investment protection

• An integrated systems approach to embedded services that speeds application deployment and reduces operating costs and complexity

For the branch, Cisco provides a portfolio of routers designed for secure wire-speed delivery of concurrent wireless, data, voice, and video services with superior investment protection. Cisco integrated services routers embed security, mobility, LAN switching, and voice services inside the router as a single resilient system for ease of deployment, simplified management, and lower operating costs. They also support leading-edge WAN technologies, such as:

• Optimized Edge Routing (OER), which helps enable intelligent network-traffic load distribution and dynamic failure detection of data paths at the WAN edge

• Group Encrypted Transport (GET) VPNs, a highly-scalable, tunnelless form of virtual private networking

• Wide-Area Application Services (WAAS), which combine application acceleration technologies with WAN optimization techniques

In addition to convenience, the Cisco integrated services routers provide investment protection. The integrated design enables a 70 percent reduction in operational expenses when compared to deploying multiple overlaid components in a branch to achieve the same services. Additionally, the modular design of the Cisco integrated services routers allows for easy integration of new services as well as the expansion of existing ones.

Switching

Cisco offers a comprehensive portfolio of intelligent network switches, with a continuously expanding suite of intelligent services and advanced technologies to strengthen, simplify, and extend the value of the network infrastructure. As a leader in switching technology innovation, Cisco is constantly developing new ways to enable its customers to get more from their network infrastructure. Many Cisco innovations have evolved into industry standards, including Cisco EtherChannel ® (now the 802.3AD standard), Power over Ethernet (now the 802.3af standard), Multiple Instance Spanning Tree (now the 802.1s standard), and Interswitch Link (now the 802.1q standard).
Cisco Catalyst switches are based on a superior design that employs a centralized architecture, which simplifies expansion and upgrades. They also use application-specific integrated circuit (ASIC) technology, which is better suited than merchant silicon (used by many other switch vendors) for the delivery of advanced features.
Additionally, Cisco Catalyst switches provide:

• Superior service delivery from the wiring closet to the core, from the data center to the WAN edge with 10/100/1000 to the desktop, Fast Ethernet through 10 Gigabit Ethernet connections, and predictable wire-rate switching performance (even with QoS enabled)

• High level of availability with In-Service Software Upgrade (ISSU) and hot-swappable modules, which enable easy upgrades without service interruption, and nonstop forwarding with stateful switchover (NSF/SSO), which reduces the mean time to repair (MTTR) by allowing extremely fast supervisor switchover that is virtually transparent

• Exceptional scalability through options such as virtualization, which provides for the centralization of services and security policies while preserving the high-availability, manageability, security, and scalability benefits of the existing campus design (centralized management and security),

• Superior security with integrated support for identity-based access control and Cisco Catalyst integrated security features, as well as firewall and intrusion detection modules

• Industry-leading support for converged applications, including voice, video over IP, and mobility
