ViBE - Voice over IP BandWidth Enhancement

ViBE Overview

The Problems Associated with Broadband ( ADSL ) Links and Voice


On the face of it, broadband should be a medium which is ideally suited for linking multiple sites for the purposes of voice and data, as well as VoIP links to external telephony providers. However, there are some very real problems associated with using voice and data over an ADSL network.

  • The asynchronous nature of ADSL means that there is much lower bandwidth upstream when compared to down. Since voice calls are by their very nature symmetrical in terms of bandwidth requirements, the number of simultaneous conversations that can be maintained is limited by the much slower upload speed ( typically 256Kbit/s. )
  • Voice information can be compressed ( using similar techniques to MP3 music compression ) to use only 8kbit/s per call. However, due to the way in which it is packaged to be sent over a broadband network, the reality is that each call will use at least 42kbit/s – significantly higher.
  • In order to allow voice and data to share the same network, QoS has to be employed. Standard QoS techniques do not work very well for voice carried over links with less than about 1000Kbit/s, and are not ideal even well above that. The effect of this is that voice information gets delayed because it has to wait for a free slot on the link in order to be sent – since peoples voices do not generally incorporate such delays this causes issues with voice quality.
  • In addition, standard QoS techniques can not allocate more than 70% of the available link bandwidth reliably. This means that on a standard broadband link, three calls is the absolute maximum that can sensibly be achieved, and the quality of those calls will still suffer where data is present.
  • On a standard BT Wholesale broadband link, no QoS can be applied in the download direction.
  • Broadband is usually part of a public or at least shared network, making security a concern.


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.


ViBE Deployment

ViBE - Service Provider Deployment


For ViBE to be deployed in a service providers infrastructure there are two seperate elements. The CPE which consists of a small footprint, diskless PC with dual LAN ports. This device sits between the DSL router and the LAN switch and captures all traffic. The device simply strips out all repetitive data before sending the payload to the router in as small a size as possible. In the core of the network, a Server based platform (or multiple platforms if resilience is required) is deployed to rebuild the traffic and deliver it on to its destination. This may be another Vibe link as part of a private network, an IP telephony provider or any form of data to any internet location.

ViBE - Enterprise Deployment


In a Point to Point scenario, a ViBE CPE device is installed at each location and is able to support up to 100 concurrent calls (G729a) on a 2mb circuit while still supporting data. Smaller devices are available for link speeds of 256k,512k or 1mb if required. For multi-site networks, a larger server device can be installed at the central site to service many remote CPE units. This type of deployment is sized on number of devices and concurrency of calls.

ViBE - CPE platform


The ViBE CPE platform is deployed between the edge router and the LAN. It captures all VoIP traffic and strips out the repetitive transport inherent with VoIP getting a G729a call down to 8.1k from it's original 29.6k on Ethernet or 42.4k on ADSL. Once processed, the VoIP is sent to the central ViBE platform in a significantly reduced state to be rebuilt and sent on to the PBX or IP Centrex platform. The CPE device will in addition improve the availability of bandwidth for all other data applications ensuring links are fully utilised.

Example


ViBE Point to Point Network Solutions


Deployed as a Point to Point solution in your enterprise ViBE technology enables your iPBX to truly function as intended.

Patent pending ViBE VPN QoS and compression technology guarantees voice quality by ensuring that VoIP traffic is efficiently and effectively prioritised at byte level within your network. Using ViBE technology also means that you no longer need as much expensive bandwidth to carry VoIP traffic between your VoIP enabled PBX and remote office locations.

ViBE virtually eliminates packet overhead, reducing the bandwidth required by a codec to its original size. In fact ViBE is so efficient that it can allow a 256K data link to carry 28 simultaneous G729 calls.

In SIP Trunking applications the use of ViBE technology can allow an existing PRI to be replaced with a single 256K ADSL circuit. Gone are the days of high cost leased lines or SDSL circuits, VoIP replacement of PRI circuits becomes a truly cost effective and viable alternative to traditional ISDN30 and ViBE allows a 'peace of mind' failover option via Basic Rate ISDN data circuits.

By using lower cost dedicated ADSL links to carry VoIP traffic, ViBE enabled point to point links can normally be installed much quicker than leased line or SDSL circuits and will show significant cost savings, even in year one. Over the life of your new iPBX ViBE could save you tens of thousands of pounds in expensive leased line circuit costs.

For organisations that already have leased lines between sites and would like to use these for VoIP traffic, ViBE provides a method of maximising existing investment by reducing the amount of bandwidth required for the added VoIP traffic, and by implementing ViBE QoS over the circuit, can guarantee the quality of the voice calls.

Where a single new VoIP enabled PBX is being used to replace older multiple PBX installations, and there are no established data links between sites, ViBE allows the use of lower bandwidth and therefore more cost effective technologies. Through its ability to use ADSL links, ViBE can dramatically reduce the lead time for installation when compared with leased line circuits.

ViBE can even be deployed between a company and its employees working from SOHO locations and using VoIP telephony over ADSL. Unlike the QoS options found on some ADSL modems a ViBE enabled ADSL modem works with a ViBE server device to control data both to and from the remote site ensuring VoIP data is efficiently and effectively prioritised, guaranteeing voice call quality while the ViBE IP VPN continues to allow online access to company information.

To deploy ViBE Technology requires a minimum of one ViBE Point to Point Server device and either a ViBE router or ViBE enabled ADSL modem at the remote site.

Voipex point to point devices for ViBE range from a simple low cost ViBE enabled ADSL modem for SOHO applications, through medium sized routers and servers for leased line applications, to high end ViBE server appliances for installation in sites that need to support multiple leased lines and possibly many SOHO users.


ViBE For VoIP PBX Resellers


Deployed as a point to point solution between sites, or over a SIP trunk connection, patent pending ViBE technology reduces bandwidth requirement so effectively that a single 256K ADSL circuit can carry 28 G729 calls with no loss of call quality. In fact ViBE guarantees voice quality by ensuring that VoIP traffic is efficiently and effectively prioritised at byte level, reducing jitter and preventing call break-up. ViBE technology gives you the edge when it comes to ensuring call quality at a competitive price.

In SIP Trunking applications the use of ViBE technology can allow an existing PRI to be replaced with a single 256K ADSL circuit. Gone are the days of high cost leased lines or SDSL circuits, VoIP replacement of PRI circuits becomes a truly cost effective and viable alternative to traditional ISDN30 and ViBE allows a “peace of mind” redundancy option via Basic Rate ISDN data circuits.

For organisations that already have leased lines between sites and would like to use these for VoIP traffic, ViBE provides a method of maximising existing investment by reducing the amount of bandwidth required for the added VoIP traffic, and by implementing ViBE QoS over the circuit, can guarantee the quality of the voice calls.

Installing ViBE within a customer's existing infrastructure alongside a new VoIP enabled PBX could mean the difference between cost effective, guaranteed quality calls and a system that works most of the time - but never during that crucial sales call.

dynamically allocates bandwidth as it is required and provides byte level QoS over the circuit. ViBE can also allow you to offer higher bandwidth, higher quality codecs without having to sacrifice too much bandwidth.

For the customer ViBE can be integrated into a number of existing ADSL modems and broadband routers so that the cost of implementation is kept down.

By using ViBE ISPs can now offer a cost effective and quick to implement alternative to traditional leased lines for VoIP applications. Using uncontended ADSL tails and routing within a ViBE enabled network it is possible to offer a service that competes directly with SDSL or leased lines but is quicker to install and more cost effective.

Because ViBE provides true QoS in both directions it is Ideal for home workers who need to use VoIP telephony over ADSL and still need to access company information over the Internet at the same time.

A single ViBE server appliance can pay for itself in under 4 months and allow an ISP to generate significant extra revenue.
