MVTS II consists of two functional layers: the switching layer, comprised of one or more Traffic Switches (TS), and the management layer referred to as Traffic Manager (TM).
Traffic Switch (TS)
Traffic Switch (TS) handles VoIP calls according to the logic provided by Traffic Manager, generates call session data, and acts as an SBC, ensuring protocol translation and normalization, network topology hiding, DoS attack
prevention, NAT traversal, and codec conversion.
TS incorporates the following main types of functional
modules:
Signaling Nodes – signaling processing and SIP<->H.323 conversion
Media Nodes – RTP traffic proxying and codec conversion
MVTS II supports license-dependent dynamic load that ensures automatic distribution of traffic between servers based on their current workload.
Distributed architecture of the MVTS II switching layer allows for:
excellent scalability and high fault tolerance
building geographically distributed networks with a single point management and data entry
flexibility and ease of adding additional servers into a cluster
In case of a hardware fault in any of the system’s
components, its functions are automatically taken over by
other servers in the cluster, assuring business-critical
system dependability.
Traffic Manager (TM)
Traffic Manager contains the system’s intellect
and repository of data. It’s an Oracle-based routing and billing core of the system and the central point of storage for all configuration, statistical, CDR, and billing data. Traffic Manager is also responsible for authentications and call admission control, call routing algorithms, statistical analysis, notifications and alerting, and Web GUI management.
