Network Switches

Technology Overview

Learn how network switches work to manage local-area network (LAN) traffic patterns, software applications, and hardware devices for maximum performance.

Network Switches

Make Your Network Efficient, Reliable, and Secure

As your business grows, innovative network switches can protect your investment while preparing you for the future.

Network switches are at the core of all networks. They provide high-speed connectivity to applications and communications systems, and efficiently and securely transmit bandwidth-intensive data, voice, video, and wireless applications. Local-area networks (LANs) rely on network switches to manage traffic patterns, support new services, and optimize application performance.

To meet current and future network requirements, network switches should offer the following functionality:

  • Application Intelligence: Today’s network switches must recognize many types of applications. They also should be able to help secure and set priorities for applications running on the network to provide the best user experience.
  • Unified Network Services: Network switches can now apply security, scalability and services consistently across the network. Network switches combine the best elements of wireless networking and wired networking to connect to any resource or person through any device.
  • Nonstop Communications: Network switches can prevent communication interruptions through existing features and capabilities like redundant hardware, non-stop forwarding, in-service software upgrades (ISSU), and software modularity.
  • Virtualization: By supporting dynamic resource and service utilization over a shared infrastructure, network switches allow businesses to adopt new services on a common, virtualized network. This helps to enable highly secure access to network resources for guests and contractors, and provides department segregation for business compliance.
  • Integrated Security: Network switches are the first line of defense against internal security attacks. They also prevent unauthorized users from entering the network. Security services provided by network switches include Network Admission Control and integrated security service modules that help enable virtual private networks, firewalls, intrusion prevention, intrusion detection, and other security services.
  • Operational Manageability: IT staff needs the ability to remotely configure and monitor network devices from a central location. They also need to automate responses with embedded event management, and use real-time diagnostic management tools to troubleshoot the LAN and apply changes.
