ViBE has always been available as a standalone VPN technology enabling full QoS to be offered across a variety of connectivity types including ADSL. Customers now wishing to deploy ViBE as part of an existing or new MPLS network can now do so with version 3’s enhancement delivering Policy Based Routing and the ability to configure multiple virtual connections to a ViBE appliance device such as an SPS-601. This allows for the virtualisation of multiple VPNs and reduces the requirement for additional dedicated hardware for each configured VPN at the enterprise level. It also allows service providers to create MPLS-VPN type functionality even if their core network is not MPLS enabled.
ViBE now allows multiple tunnels to be configured to a single end device or CPE. This enables increased flexibility as to how Voice and Data can be transmitted with ViBE and allows the core network to treat the voice and data tunnels differently. RAIN mode can be configured individually for voice and data tunnels, for example it can be set for voice only whilst data can be transmitted across a standard bonded connection. This helps greatly in reducing the amount of bandwidth used when unnecessarily transmitting voice and data simultaneously across RAIN configured links. Data, which is less susceptible to packet loss, may be sent independently and not duplicated. Voice on the other hand can now be duplicated across two links to minimise the effects of, say, packet loss.
User permissions and security
The ViBE management interface now has increased flexibility to provide permissions based on no access, view only or full access on a page by page basis. This greatly increases the integrity of the system and existing reliance on one master user.
EsP or “Estimated Performance” is a new and unique feature from Voipex that allows ViBE to continuously monitor the real bandwidth available on the underlying link. In turn, this enables ViBE to both maintain the integrity of its QoS profiles and to control call access in order to avoid over-subscription. This feature is specifically designed to counter the effects of variable bandwidth links such as 3G, or cases where there may be congestion in the core network.
Keep alives are ViBE’s way of understanding whether a link is functioning effectively and whether a failover condition should be actioned. Keep Alives are configurable by the user and normally work to a sub-second rate to ensure calls are maintained in the event of a failover. There is now further Keep Alive functionality available that allows the user to configure the rate based on a scenario when calls are in progress and when calls are not in progress. The theory being that ViBE can be less aggressive during low or no call periods such as out of hours vs times when there are call in progress. The result of this is that less bandwidth is used overall by the Keep Alive packet transmission over the course of a day, week or month.
SIP signalling does not work effectively in NAT based environments. Since ViBE is a VPN technology, networks using it can eliminate the requirement to use NAT in many situations. This feature is particularly important in hosted IP-PBX environments. In cases where NAT is still desirable, the availability of a SIP-ALG on ViBE enabled CPE devices such as the Mikrotik, Billion and proprietary devices, means that there are more options available to the service provider when trying to solve SIP/NAT conflicts.
Receive News from Voipex
ViBE provides real-time monitoring of underlying link quality and its effect on voice. Packet loss, latency and jitter are also monitored. ViBE's monitoring is not affected by link loading and any faults with the link (ADSL down for example) can be distinguished from customer created ones.
ViBE can be deployed in either a point-to-point configuration or a service provider/enterprise configuration.
Typical Service Provider / Enterprise Configuration
For deployments with a high number of geographical sites ViBE can be installed in a Central Server configuration (usually in a Hosting Environment) with satellite sites each having a smaller ViBE enabled device installed on the end of the connecting link. ViBE can be setup in N+1 configuration at the core of any enterprise/service provider.
ViBE (Voice over IP Broadband Enhancement) helps to solve many of the everyday issues that are experienced when trying to make VoIP work effectively ‘in the real world’ in several important ways:
Business grade quality on VoIP calls
: ViBE is perfect for any size of business or organisation that uses VoIP based telephony. ViBE is also a good fit for any business looking to make the move to a VoIP based system.
Service Providers will also benefit significantly from ViBE by deploying it over their networks to benefit their own VoIP service.
: This depends on how your ISP or distributor has packaged ViBE check with your approved reseller or distributor.
Voipex offers a comprehensive range of support options that are designed to maximise your ViBE experience.
