Acme Packet ETC NIU, 002-0618-58, NGI7AZDSAA Enhanced Traffic Control Networking Interface Unit version 1 for Net-Net 4500. Oracle PN: 7107433
The ETC NIU contains one Cavium hardware chip that provides encryption/decryption. In order to
support 10,000 concurrent sessions and overcome the 1 GB bandwidth limitation per port, a major design
goal is to split the traffic between any 2 ports on ingress and remaining 2 ports on egress. Upon reaching
10,000 concurrent sessions limit, subsequent calls will be rejected.
Enhanced Traffic Control NIU
The Net-Net 4500 Enhanced Traffic Control (ETC) NIU offers a unique and highly-advanced design, with enhanced capabilities
that address a wide range of next-generation services and applications.
The ETC NIU is a high performance multi-processor engine that combines multiple hardware-accelerated functions including:
• High-capacity SRTP encryption
• High-capacity termination for SIP-TLS
• Separate, dedicated processors for high capacity IPsec encryption and TCP termination
• Integrated hardware for QoS monitoring and reporting
The extensible multi-core, multiprocessor architecture of the ETC NIU is capable of supporting additional applications and
functions as new requirements emerge.
