ViBE
Key Features
Key features include:
- Customised QoS, designed for voice
Existing QoS was designed to manage bandwidth as best as possible for multiple applications, it falls short of being able to cope with real time requirements such as voice. ViBE addresses this issue by using custom methods to guarantee quality of service for real time applications. - Reduced bandwidth requirements
G.729 calls require 42kbps of bandwidth when transmitted over a broadband link due to overheads, whereas the actual voice data only needs 8kbps. ViBE removes many of these overheads and maximises the bandwidth usage. - VPN support
ViBE can be configured to create one or more virtual private networks between several sites, ensuring that your voice and data remain secure. - Resiliency control
ViBE can intelligently control resiliency options on the IP network in order to ensure continuity of calls. ViBE will detect a network failure in less than one second and take remedial action. - Multiple IP link bonding
Multiple links can be bonded efficiently, so for example, two standard 512Kb / 256Kb broadband lines could be used to manage 50 simultaneous calls at the same time as having 512Kbits/s of upload data (available Q4 2007). - Reduced call jitter
Average call jitter across the WAN is reduced to the order of 1ms whether or not data is present on the same link. This compares with more than 100ms of jitter typically found on a standard broadband connection. - Reduced call latency
End to end latency is reduced, especially in the presence of high data loads. With standard broadband, end to end latency can easily rise above 100ms, causing conversations to become disjointed. ViBE completely eliminates this problem. - Link quality monitoring
Optional reporting generates statistics such as the number of simultaneous calls over time, link latency, uptime, and packet loss, as well as call jitter (available Q4 2007).
