Brett Lewis discusses redundant network design at the February 2009 1Velocity Breakfast Seminar on Business Continuity.
Network uptime becomes more critical every year. During an unforeseen service interruption, a redundant network automatically switches to an alternate route, protecting critical elements of the network. Learn the keys to keeping your mission-critical connectivity running as usual during outages with a truly diverse infrastructure.
2. Why ?
• Every organization, no matter what the industry,
faces significant risks when voice and data
communications are interrupted
▫ Productivity comes to a halt
▫ Transactions cannot be processed
▫ Critical applications go offline
▫ Employees can’t serve customers
▫ Liability and fraud exposure increases
3. What is redundancy ?
• “2” connections utilizing “2” diverse routes and
“2” separate carriers combining at the same
destination supplying a single service.
4. Facts about Carriers
• 85% of all municipal carriers share the same
middle mile ingress and egress conduits and
connections.
• 95% of all municipal carriers share the same last
mile switching and terminations.
• 98% of all Tier 3 Internet Carriers use the local
municipal carriers for last mile access.
5. 2 Internet Carriers
• Two carriers that have diverse egress routes out
of the local area
• Two carriers that have diverse ingress routes to
your location.
7. 2 WAN Carriers
• Two carriers that can scale their capacity to
become the primary carrier at any moment.
• Two carriers that are not subject to the same
environmental impacts.
▫ Line cuts
▫ Rain
▫ Weather
▫ Construction
10. Summary
• True redundancy requires 2 of all core services
with a single destination
• 85% of all carriers share conduit and leased line
• Utilizing different connectivity and networking
technologies can assist in creating a truly
redundant network.
