What Does Cisco Attract You?

Cisco provides a network that can securely and reliably handle all types of traffic, throughout the entire network, over virtually any media, while providing consistent service delivery to all users.

Cisco is proud of being a recognized worldwide leader in networking. Now, when the technology industry is going through a period of dramatic change, it 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.

Innovation, something indispensable, helps Cisco and famous companies win customers’ praise. And this reputation is caused in part by the Cisco development strategy of "build, partner, and acquire." Beyond corporate innovation, Cisco also helps to shape innovation throughout the industry by actively participating in virtually every group concerned with networking standards.

To be simple, as a company whose own success depends on its network systems, Cisco fully understands this relationship. In today's environment of mergers, acquisitions, and global expansion, businesses now require network systems that enable technology innovation and business-critical services not only at the headquarters, but across geographically disparate corporate campuses, throughout the branches, and out to remote workers. Cisco can provide an end-to-end network, composed of systems specifically designed to address the unique needs of each place in the network, connected by a common infrastructure and a common operating system and manageable from a central location as a single, cohesive entity.

Because Cisco envisions the network as a whole, it designs and develops products, technologies, and solutions that provide business benefits across the entire network. Consider, for example, the enablement of advanced technologies. Advanced technologies, such as voice over IP (VoIP), require the support of intelligent network services. Although many networking vendors support these services, the level and methods of support often vary from one device to another and from one place in the network to another, making configuration and interoperation difficult. With Cisco network systems, intelligent network services, such as quality of service (QoS) and encryption, are consistently supported and preserved across the entire network, enabling the same secure and high-quality service delivery regardless of whether the user is at headquarters or in a local branch.

Cisco applies this same broad view to network management, providing tools to manage the network as a whole. For example, the Cisco integrated services routers use 802.1ag to provide end-to-end service manageability. Another example is the Cisco Network Application Analysis (NAPA) Solution, which also takes a holistic approach to management, providing an end-to-end view as it monitors and analyzes the entire network to optimize the relationship between application performance and network resources.

Moreover, Cisco understands the relationship between all elements of the network: that an improvement in management or security capabilities can often mean a decrease in performance. Cisco is constantly looking for innovative ways to eliminate these types of tradeoffs. One such innovation is the Cisco Catalyst 6500 Supervisor Engine 32 Programmable Intelligent Services Accelerator (PISA), which eliminates the tradeoff by providing hardware acceleration of intelligent services, such as stateful application intelligence and day-zero security services, at multigigabit speeds.

In most cases, the network of a company or organization is not a single island. It is likely made up of multiple networks, including one or more campuses, some number of branches, remote teleworkers, and one or more data centers, all connected through a WAN or MAN. These businesses and organizations require solutions that work across the entire network, throughout all "places in the network."

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.

Cisco gives branch users an equal status with the Empowered Branch, which integrates the widest set of services and applications while optimizing their interoperability and performance for a consistent branch experience. At the WAN headend, Cisco offers services aggregation solutions that combine virtualized services integration, bandwidth optimization, and application intelligence to provide secure, intelligent routing of applications across the enterprise WAN.

• 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 You Need to Know

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.

At the headend, Cisco offers an extensive WAN and MAN aggregation platform portfolio, which also provides a comprehensive set of highly secure, concurrent, and integrated services. Cisco services aggregation routers provide exceptional performance with aggregation speeds of up to 2 Mpps and support for as many as 16,000 Point-to-Point Protocol (PPP) sessions and 5000 VPN sessions per chassis. For optimization, these routers also support Network-Based Application Recognition for application optimization and OER. To help ensure the security of your network, these routers include support for IP Security (IPsec) encryption, an integrated stateful firewall, and support for identity-based access control.

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), and Power over Ethernet, which simplifies the addition of new endpoints

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

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

For your business growth and success, this network should be a Cisco network.
