Pre-IMS

Radware’s VoIP/SIP Application Front End (AFE) solution guarantees reliable, scalable, accelerated and secure delivery of session initiation protocol (SIP) services across session border controllers (SBC) and other SIP-aware network elements, while affording significant CAPEX savings. Extending subscriber, service and content awareness, our solution delivers the intelligence needed to address VoIP/SIP service delivery requirements of advanced operators, including the identification of both IP multimedia subsystem (IMS) and non-IMS subscribers and services, as well as access network type. VoIP AFE affords

• SIP service availability and scalability through SIP layer health monitoring, server availability load measurements, persistency, SIP virtualization, local and global (multisite) redundancy
• SIP service acceleration through optimized connection admission control (CAC) and bandwidth management
• SIP service security employing adaptive, behavioral intrusion protection system (IPS) and Distributed Denial of service (DDoS) security for zero-touch, zero-minute, zero-false positives to block SIP-based floods and identify misbehaving customers, mitigating attacks targeting the SBC layer, flash crowd scenarios and BOT attacks against SIP-aware devices within the trusted domain*
