SMARTER WAYS

OF NETWORKING

CISCO SYSTEMS, THE WORLDWIDE LEADER

IN END-TO-END NETWORKING SOLUTIONS,

PROVIDES THE BROADEST RANGE OF

SOLUTIONS FOR TRANSPORTING DATA, VOICE,

AND VIDEO, WITHIN BUILDINGS AND OFFICES

AROUND THE WORLD.

TODAY, NETWORKING SOLUTIONS ARE AN

ESSENTIAL PART OF BUSINESS. CISCO CAN

HELP ASSURE THE HIGHEST LEVELS OF

SECURITY, RELIABILITY, AND PERFORMANCE,

BECAUSE THE SAME CISCO TECHNOLOGY

THAT IS POWERING THE VAST MAJORITY OF

TODAY’S BUSINESS NETWORKS WORLDWIDE

IS ALSO POWERING OURS.

END-TO-END SOLUTIONS

CISCO OFFERS ROUTERS, SWITCHES, SECURITY DEVICES, VPNs,

WIRELESS LANs (WLANs), AND THE SOFTWARE NECESSARY TO

INTEGRATE EACH ELEMENT INTO A SECURE, PRODUCTIVE, RELIABLE,

AND EASY-TO-MANAGE NETWORK. THIS UNIQUE END-TO-END

SOLUTION PROVIDES THE SIMPLICITY EVERY BUSINESS NEEDS.

>

Integrated, end-to-end security—To safeguard confidential business data, a Cisco network provides enhanced security that protects the network from internal and external threats.

An integrated security solution also simplifies security management and greatly reduces the total cost of ownership of the network.

>

High network availability—A Cisco network helps ensure the reliable network access and maximum uptime that companies depend on to support new users, open new offices, deploy new services, extend their networks to customers and partners, support a more mobile workforce, and more. Cisco switches and routers include support for network and link redundancy, dynamic routing, automatic failover, and redundant power for improved fault tolerance and network availability.

>

Predictable performance—Intelligent end-to-end management maximizes the availability and performance of critical applications.

Cost-conscious small and medium-sized businesses (SMBs) can maximize WAN bandwidth to serve more users and conduct more business over the Internet without upgrading to more expensive WAN facilities.

>

Ease of use—Cisco’s intuitive end-to-end Web-based management helps keep administrative expenses down—even as the network expands.

>

Cost-effectiveness—An end-to-end solution approach reduces complexity and network management costs. Modular and scalable products help reduce costs of future expansion.

>

Investment protection—Customers can receive trade-in value for existing Cisco products against the purchase of new Cisco products.

GLOSSARY

100BASE-FX – 100-Mbps fixed uplink configuration

1000BASE-T – The Gigabit Ethernet standard (1 gigabit is 1000 megabits per second) using four pairs of Category 5 (CAT-5) and above Unshielded Twisted Pair (UTP) copper cables.

Advanced Encryption Standard (AES) – A new encryption algorithm that is set to replace the DES algorithm. It uses a secret key of variable length (128 to 256 bits) to provide symmetric encryption for data in the IP Security (IPSec) suite of protocols.

Asymmetric Digital Subscriber Line (ADSL) – A technology for transmitting digital information at high bandwidth on existing phone lines to homes and businesses. Provides a continuously available, “always on” connection.

Bridge – Connects one LAN to another using the same protocol.

Cisco IOS Software – The standard operating system used by all Cisco internetworking solutions. It provides a solution that is secure, highly resilient, easy to manage, scalable, and flexible, enabling new technologies to be deployed quickly and without heavy reinvestment. Cisco IOS Software is the most widely used internetworking operating system, providing further assurance of interoperation and reliability

Data Encryption Standard (DES) – A widely used encryption algorithm that has been used as a default for the last 20 years.

There are two principle key lengths, 56-bit for DES and 168-bit for

Triple DES (3DES). DES is accepted as being unbreakable except by brute force (trying every key permutation), and is part of the suite of IPSec protocols.

Demilitarised zone (DMZ) – A computer host or small network inserted as a “neutral zone” between a company’s private network and the outside public network. A DMZ prevents direct access to servers storing company data and provides greater security than a firewall.

Ethernet – The most widely installed LAN technology. The most common Ethernet systems are 10BASE-T, providing transmission speeds of up to 10 Mbps.

Firewall – A security system designed to protect a network against external threats, such as hackers.

Gigabit – A transfer rate of 1000 Mbps.

Gigabit interface converter (GBIC) – An optical or copper transceiver for flexible connections, up to and including gigabit speed, over different types of media.

IEEE – The Institute of Electrical and Electronics Engineers, notable for developing national and international standards.

IEEE 802.11

– The formal standard for the wireless networking protocol.

Integrated Services Digital Network (ISDN) – A set of standards for digital transmission over ordinary telephone copper wire and other media.

Intranet – A private network created within a business or organization.

Intrusion detection system (IDS) – A security countermeasure that monitors data traffic and events, looking for signs of intruders.

GLOSSARY

(CONTINUED)

IP Security (IPSec) – A suite of protocols that provides authentication, integrity, and encryption algorithms.

LAN – A group of computers and associated devices sharing a common communications line or wireless link and typically sharing the resources of a single processor or server within a small geographic area (within an office building, for example).

Megabits per second (Mbps) – Data transfer speed measured in multiples of 1 million bits per second.

Modular (chassis) switch – An upgradable switch with flexible capabilities.

Quality of service (QoS) – For optimum efficiency, the QoS component of Cisco IOS Software enables networks to control and provide predictable service to numerous applications, allocating priority, dedicating bandwidth, and controlling jitter and latency.

Router – A device that moves data between different network segments and can look into a packet header to determine the best path for the packet to travel. Routers can connect network segments that use different protocols. They also allow all users in a network to share a single connection to the Internet or WAN.

Small Form Factor Pluggable (SFP) – A flexible port on Cisco Catalyst switches that can be configured with different types of copper or

Fibre uplinks (sold separately).

Stackable switch – A switch that can stack several physical units together to make a single logical entity.

Switch – A device that improves network performance by segmenting the network. When a switch port receives data packets, it forwards those packets only to the appropriate port for the intended recipient.

This capability further reduces competition for bandwidth between the clients, servers, or workgroups connected to each switch port.

Uplinks

• High-speed link to the backbone, server, or router.

• Copper uplinks are based on CAT-5 cabling and above, and can be used for distances of up to 100 meters.

• Fiber-optic uplinks are used for greater distances, or where copper is not practical.

VPN – A secure tunnel across the Internet through which data, video, and voice traffic can be transmitted.

WAN – A network that connects devices over great distances, such as geographical regions. A WAN often connects two or more LANs.

See also LAN.
