In today's market environment, both wholesale and retail service providers are required to support interconnection and peering between networks with diverse technologies, protocols and signaling standards. Proliferation of VoIP SIP networks is driving the need for direct IP connectivity between different carrier networks. However, carriers continue to have lingering concerns about security, reliability and accounting that has hampered the large-scale deployment of IP peering solutions. The Veraz Global Carrier Peering Network Switching solution provides a comprehensive solution that fully addresses the security, routing, billing and protocol interworking requirements for peering across both IP and TDM networks.
The Veraz solution provides the widest possible interconnectivity & peering between different types of IP and TDM networks through support for seamless any-to-any interworking between IP protocols (such as H.323, SIP, MGCP, H.248) and TDM signaling standards (multi-national variants of SS7 & PRI). The Veraz solution is the only next-generation solution that supports Open Settlement Protocol (OSP), which is a proven, long-standing solution for secure carrier peering. The solution is also designed to interoperate with standards-based 3rd party Border Gateways offering the MIDCOM "middle box communication" architecture. This allows global carriers to maximize operational efficiency and the minutes transported through their network by peering with the widest possible range of carriers.
Advanced security features enable carriers to prevent malicious attacks on their network and ensure that their customers' assets are fully protected. Some of the key security features include topology hiding to hide internal network & customer details, access control lists for "denial of service" attack prevention, and far-end & near-end NAT traversal to avoid NAT/Firewall complications. For additional details on security, refer to the relevant Network Security Solution.
The ControlSwitch™'s programmable policy engine provides fine-grained control over routing and service policies leading to maximum call-completion rates and optimal usage of network resources. Furthermore, built-in QoS policies allow carriers to gain control of their network-wide quality of service and ensure compliance with SLA requirements. Centrally managed peering policies consistent across all TDM and VoIP protocols offer ease of management and cost-effectiveness for global carriers peering with different types of networks.
The fully distributed, modular architecture of the ControlSwitch™ provides unmatched flexibility and cost-effectiveness for distributed deployments by allowing carriers to adopt a granular, "pay-as-you-grow" strategy for scaling their networks. Carrier-class reliability is maintained in such a distributed environment through a sophisticated, high-availability architecture with support for device, network and geographic redundancy. The industry-leading voice quality and compression characteristics of the I-Gate 4000 family of media gateways ensure toll-quality voice and optimal bandwidth efficiency over both TDM and IP networks.
