High Availability Networks

Mitel MiVoice MX-ONE that is a communication system offering real time voice capability requires a high availability network. Mitel recommends that partners and customer follow the best practice in the market regarding high avail- ability network design. A well-designed network reduces considerably the risk of failure, and it increases the uptime of whole solution.

A robust network can be built using mechanisms/techniques that are very well known in the market. For instance, some mechanisms/techniques that need to be taken in consideration are to build a layered Local Area Network (access, distribution and core layers), reduce the broadcast domains, enable QoS, avoid single point of failures and use redundant paths. Furthermore, basic techniques like Spanning Tree Protocol, Rapid Spanning Tree Protocol, Virtual Router Redundancy Protocol, Link aggregation (bonding) are highly recommended when building a redundant network for MiVoice MX-ONE. Additionally, use redundant network devices and make sure that switches and routers have duplicated power supply.

Moreover, when Service Node, Media Gateways and IP telephones are deployed over WAN (Wide Area Network) be sure to make it as much available as possible. Always try to avoid common WAN single point of failures, use a second link, preferable via a second provider and enable end to end QoS.
