Use Available Network Resources Efficiently

By using network virtualization solutions, network resources can be deployed and managed as logical services, rather than physical resources. As a result, companies can:

  • Enhance enterprise agility.
  • Improve network efficiency.
  • Reduce capital and operational costs.
  • Maintain high standards of security, scalability, manageability, and availability throughout the campus design.

Network virtualization solutions can consolidate multiple physical networks into one virtual network. They can also logically segment a single physical network into multiple logical networks. Partitions can be added to rapidly scale the network for business needs.

Cisco Catalyst switches, including the Catalyst 6500, 4500, 3750, and 3560 Series, can adopt the LAN Virtualization framework to improve efficiencies and save on costs even as technical requirements increase.

Cisco network virtualization solutions address three important aspects of network virtualization:

  • Access control
  • Path isolation
  • Services edge

Access control provides secure, customized access for individuals and groups to protect the Enterprise LAN from external threats. Complementary features include:

  • Port authentication using standards such as IEEE 802.1x for strong connections between authorized users and VPNs.
  • Cisco Network Admission Control (NAC), to minimize security risks by removing harmful traffic.

Path isolation maps validated users or devices to the correct secure set of available resources (virtual private network, or VPN). Cisco offers three path isolation solutions:

  • Generic routing encapsulation (GRE) tunnels create closed user groups on the Enterprise LAN to allow guest access to the Internet, while preventing access to internal resources.
  • Virtual routing and forwarding (VRF)-lite, allows network managers to use a single routing device to support multiple virtual routers.
  • Multiprotocol label switching (MPLS) VPNs also partition a campus network for closed user groups

Services Edge provides access to services for a legitimate sets of users and devices, by using centralized policy enforcement to:

  • Minimize capital and operational expenses.
  • Share service modules across all partitions of the network.
  • Rapidly deploy policies and services across the whole network.
