MVTS Pro Architecture

Modular architecture of MVTS Pro allows for optimization of the system's capacity use, enables flexible approach to proxy mode and ensures business-critical dependability.

MVTS Pro comprises two functional layers: Traffic Switch and Traffic Manager, which is the main point of the system's intellect and repository of data.

Traffic Switch handles H.323, SIP , SIP-T/I, ETSI/ITU ISUP (SIGTRAN), MGCP traffic, performs codec conversion, kernel level protocol translation, and normalization, thus ensuring interworking between protocol versions and dialects.

Traffic Switch functions as a SIP Registrar, Gatekeeper, and Session Border Controller and provides an IP-to-IP connectivity interface for safe and secure interworking with customers and peering partners, as well as enables interoperability of multi-vendor equipment and hides the network topology.

Additionally, Traffic Switch is the source of call statistics, which is visualized and analyzed by means of the Traffic Manager GUI.

Traffic Switch incorporates several types of functional modules: Load Balancer/ H.323 Gatekeeper/ SIP Registrar, Call Agent, Signaling Module, Media Module, and Management Module.

Traffic Manager is responsible for authentication of VoIP endpoints, call routing, call analysis, number validation and transformation, traffic monitoring/balancing, notification and alerting.

Traffic Manager incorporates three types of functional modules: Routing module, Database and Web Server.

The Database stores MVTS Pro' configuration files and CDRs and allows data export into external billing systems. The Database can incorporate information about several million dial peers. Data retention is ensured by database backups.

Redundancy

MVTS Pro modular architecture allows various redundancy schemes which ensure a high level of dependability. The possibility to add and distribute software modules among several servers provides for effective re-distribution of traffic load and fail-safe operation of whole system.

MVTS Pro comprises a set of redundancy features to enable full reliability:

• Redundancy through load balancing
• Redundancy of all key modules providing standby items for all functional components of the system (complete back up)
• Individual redundancy of business-critical modules only (partial back up)
• “Safe configuration” mode
• Multiple traffic entry points and their redundancy
• Import and export of data, configuration updates and other procedures without interruption of service.
