The “VoIP Does Not work” ProblemThe “VoIP Does Not work” Problem
Traffic After applying control
Priority and bandwidth guarantees ensure toll-quality VoIP performance
Lack of QoS results in poor VoIP performance
Traffic Before any control

Today’s Options Are LimitedToday’s Options Are Limited
The Existing Router Network– Good at “better, faster, cheaper” forwarding of packets – Packet-by-packet control (not application-aware)– Not designed for real-time traffic guarantees– Complex to configure
MPLS Backbone – Manages delay and jitter within the core– Last mile/access point (customer edge) must still be managed
Add More Bandwidth– Dual, separate links– Increase bandwidth

These are generally network-centric solutions

Bigger WAN pipes do not guarantee better performance – VoIP packets can still be impacted by data packets and the cost increases

Converged Access’ SolutionConverged Access’ Solution
Guarantees bandwidth availability and priority for:– Voice traffic
– Mission critical data applications
Dynamic bandwidth allocation ─ makes unused bandwidth available for other applications
Optimal bandwidth use ─ more calls and less bandwidth costs
Full traffic visibility

Case Study: TV Network Lowers Costs with High-Quality News Driven VoIP/Data Solution Case Study: TV Network Lowers Costs with High-Quality News Driven VoIP/Data Solution
Challenge:– Decrease long distance
phone bills caused by telephone infrastructure for news and sports events
– Moved from satellite based circuit-switched data network to an IP backbone eased data network complexity, but voice network was still “a nightmare”
– Converge Voice & Data networks to reduce costs, simplify tasks and enable quicker implementation

– Moved from satellite based circuit-switched data network to an IP backbone eased data network complexity, but voice network was still “a nightmare”
– Converge Voice & Data networks to reduce costs, simplify tasks and enable quicker implementation
Solution:– Traffic manager installed at
several events– Monitored and classified
traffic by application– Reported detailed profile for
each event– Helped qualify the overall
health of the network: Congestion levels, latency & overall utilization
– Built a typical profile for each type of event
– Generated policy templates to pre-load and deploy traffic manager

Case Study: TV Network Lowers Costs with High-Quality News Driven VoIP/Data SolutionCase Study: TV Network Lowers Costs with High-Quality News Driven VoIP/Data Solution
Results:– Reduced bandwidth required for events from several T1’s to a
single T1
• Up to 96 compressed VoIP calls on a single T1
– Improved response times for all Latency Sensitive Data traffic because of guaranteed bandwidth
• All Non-Business traffic is monitored AND capped
– Reduced by 10 fold the time for set-up/tear-down
– Extended converged data/voice implementation to ALL fixed sites, and added video onto the network
– Increased predictability of network
• Staff gained confidence in the ability to manage and control traffic at the session level, with great reliability and repeatability
