ShowNotes: Non-Stop Networking

- December 17, 2009 - 2 Comments

Welcome to the Show Notes for TechWiseTV 57: Non-Stop Networking.

If a security breech is your worst nightmare, a network outage is probably a close second in today’s no-excuses business environment. How can you ensure continuous availability in this era of limited IT budgets? How do you achieve true redundancy without adding complexity and cost?

TechWiseTV shows you how to architect a non-stop borderless network by taking advantage of the technologies you probably already have. Discover how you can strengthen your network’s resiliency and performance by addressing its four critical areas: the core, distribution, access, and branch layers.

Learn the difference between availability and reliability and why it matters. Explore solutions that will enable you to better monitor the health of your network and minimize the impact of events that are most responsible for downtime. Find out how you can move beyond the outdated notions of five-nines reliability and achieve true non-stop performance as we teach you how to:

  • Turn on virtual switching in your network core and get rid of at least three redundancy protocols, effectively doubling your capacity
  • Increase system resilience with non-stop forwarding and stateful switchover
  • Make your wireless LAN even more resilient and robust while reducing your management burden
  • Take advantage of Dynamic Multipoint VPN to simplify branch-to-branch connectivity and reduce deployment and access costs

 


Segment 1: If the Network Fails and Nobody Notices…

The Cost of Downtime

Segment 2: Core Layer: Virtual Switching on the Cisco Catalyst 6500

Guest: Vimala Veerappan

Product Page

What is a Virtual Switching System?
A VSS is network system virtualization technology that pools multiple Cisco® Catalyst® 6500 Series Switches into one virtual switch, increasing operational efficiency, boosting nonstop communications, and scaling system bandwidth capacity to 1.4 Tbps. At the initial phase, a VSS will allow two physical Cisco Catalyst 6500 Series Switches to operate as a single logical virtual switch called a virtual switching system 1440 (VSS1440).

In-Service Software Upgrade

ISSU allows customers to virtually eliminate planned outages for full image software upgrades or downgrades. It provides the means to upgrade or downgrade the Cisco IOS® Software in a Cisco Catalyst 4500 E-Series switch with redundant supervisors. ISSU is an administrator-initiated process of CLI commands issued in a specific order.

Segment 3: Access Layer: Self-Healing Wireless

Cisco M-Drive technology helps the transition of business wireless technology to the 802.11n standard by providing a set of tools that deliver the robust, scalable wireless foundation required to realize the true potential of mobility. These tools include:

• Cisco ClientLink technology to raise uplink and downlink performance of existing 802.11a/g equipment

• Automated configuration and powering of access point

• Advanced capabilities to select data rates, adjust power, and manage QoS for access points
