How ViBE Technology Helps
Vibe ( Voice over IP Broadband Enhancement ) solves these problems in several important ways:
- Quality of Service is implemented in a completely different way to traditional methods, being much more suited to slower links.
- Voice is no longer treated as simply another type of data which happens to have a high priority. Instead, it is treated as a data stream with very specific requirements not only in terms of priority, but also in terms of spacing between packets.
- The bandwidth budget required is reduced to that of the compression format used, so that a G.729 call really does only use 8Kbit/s over the ADSL link rather than the 42Kbit/s which is more usual. Rather than a maximum of three calls, twenty-eight calls are now practical on a single broadband line.
- Voice and data can readily coexist on a single link. Data transfer rates are not compromised by the fact that voice is present. Classes of data can be given their own share of available bandwidth in a much more granular way than traditional QoS.
- Sites that have Vibe links can be joined together to form private networks, which means that security is easier to control.
- Backup links can be implemented which can be activated without losing calls in progress.
- Much more of the capacity of the link can be used.
- Future development of the technology will allow multiple links to be used as a single large bandwidth connection, offering a viable alternative to costly private circuits.
