Bandwidth Aggregation Will Not Solve Emergency VoIP Problems

There are several advantages to linking disparate network bandwidths to provide an aggregate that is more cost effective than traditional business class bandwidth prices.

The concept—known as adaptive private networking, in which varying speeds and types of network elements are used to create a reliable set of links—is being employed by a regional 911 service provider in the metropolitan Phoenix area of Maricopa.

By using Talari Networking equipment to consolidate links into a virtual WAN, the provider has been able to improve network legacy performance without paying for additional bandwidth.

Future links in the process are likely to include consumer links of 10 megabits per second of broadband service, which can be procured at less expensive rates than business-class frame relay service.

Other possibilities include the consolidation of independent systems with traffic control system and county networks, which can ideally facilitate a redundant system with greater reliability and capacity than that of traditional bandwidth service.

The process of using several independent networks with minimal sharing of physical infrastructure can eliminate isolated points of failure while maintaining routes for failover and increased availability.

“Be ready to start leveraging your relationships with different stakeholders,” said the technical manager of Arizona’s Maricopa Region 911 service, who spoke on condition of anonymity.
