The Net-Net 4500 supports two Acme Packet SBC configurations, the integrated Net-Net Session Director (SD and decomposed Net-Net Signaling Firewall (SF).
Net-Net 4500 SD
The Net-Net 4500 SD tightly integrates signaling and media control and provides comprehensive support for SIP, H.323, RTSP and MSRP signaling and media sessions. The Net-Net 4500 SD provides the session border controls that OTT/ASPs require in five critical areas—security, service reach maximization, SLA assurance, regulatory compliance, and cost and revenue management.
The Net-Net 4500 SD can also be a member of a Net-Net Cluster when used in conjunction with Acme Packet’s Net-Net 4500 Session-aware Load Balancer (SLB). Acme Packet Net-Net Clusters support up to two million subscribers without requiring architectural forklifts or network disruptions. Net-Net Clusters support all Net-Net SBC configurations.
Net-Net 4500 SF
The Net-Net 4500 Signaling Firewall (SF) provides SIP signaling security, load balancing and other controls for the subscriber access border and the interconnect/peering border. It controls access via static and dynamic ACLs, hides topology and can protect itself and other elements of the SIP service delivery infrastructure from malicious denial-of-service (DoS/DDoS) attacks and non-malicious overloads.
The Net-Net 4500 Session-aware Load Balancer (SLB) enables linear, non-disruptive SBC capacity scaling to two million subscribers from a single SIP IP address. It supports the delivery of any SIP service or application—voice, video, presence, messaging and multimedia; over any access network, including the Internet.
The Net-Net 4500 SLB is deployed with our Net-Net Session Director SBCs to create a Net-Net Cluster. The Net-Net Cluster is comprised of two-or-more Net-Net SBCs front-ended by the Net-Net SLB for SIP signaling. The Net-Net 4500 SLB is a high-performance layer 5-7 aware load balancer optimized for Acme Packet Clustering. It provides dynamic, adaptive load balancing of subscribers based on SBC availability and health score; and subscriber capacity, load and session state. Like all Net-Net solutions, the Net-Net SLB features carrier-class high-availability to ensure no loss of active sessions in the event of single system failures. Deployed as 1:1 active-standby units, the SLBs checkpoint configuration and cluster state.
The Net-Net Cluster scales subscriber capacity without requiring architectural forklifts or network disruptions. Since all elements of the cluster are SIP subscriber and session-aware, it provides a superior solution in terms of scalability, dynamic adaptive load balancing, redundancy and management compared to traditional layer 3/layer 5 web load balancers and SIP redirect servers.

Net-SAFE, Acme Packet’s security framework, is supported via the tight integration of the Net-Net 4500 hardware and Net-Net OS software. Net-SAFE features powerful denial-of-service/distributed denial-of-service protection at the layer 3, layer 4, IPsec and SIP signaling level; and it offers intrusion detection/prevention capabilities. Other security features support dynamic access control, topology hiding, privacy and confidentiality, service infrastructure DoS/DDoS protection, virus and SPIT protection, and fraud prevention.
Net-Net Central, our next-generation management platform, delivers highly-scalable configuration and fault, performance and security management for Acme Packet products and solutions. Its flexible high-availability architecture accommodates very large networks and provides extensibility for hosting advanced management application add-ons. Through its dashboard summary and multiple configuration views, Net-Net Central facilitates flow-through provisioning, capacity planning and comprehensive performance and fault-monitoring with “at-a-glance” status indicators that simplify real-time network-wide management. Through standard interfaces including SNMP, SFTP, XML and SOAP, Net-Net Central also integrates with OSS/BSS ecosystems to deliver advanced service fulfillment, service assurance, billing and mediation.
