4500 configurations
The Net-Net 4500 supports three Acme Packet SBC configurations, the integrated Net-Net Session Director (SD), decomposed Net-Net Signaling Firewall (SF) and decomposed Net-Net Border Gateway (BG). Net-Net 4500 SDThe Net-Net 4500 SD tightly integrates signaling and media control and provides comprehensive support for SIP, RTSP and MSRP signaling and media sessions. The Net-Net 4500 SD provides the session border controls that mobile service providers require in five critical areas—security, service reach maximization, SLA assurance, regulatory compliance, and cost and revenue management. The Net-Net 4500 SD supports Net-Net SMX. This configuration option adds IMS-equivalent I/S-CSCF functions to create an integrated, single system delivery solution. This solution reduces the cost of RCS, FMC and IMS-equivalent service delivery infrastructure to approximately $2-3 per subscriber for as few as 100,000 subscribers. While Net-Net SMX is ideal for initial service rollouts or small subscriber populations, it can also be scaled in several ways to support larger subscriber populations based upon service success. 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 SFThe Net-Net 4500 Signaling Firewall (SF) provides SIP signaling security, load balancing and other controls for the mobile 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. Net-Net 4500 BGThe Net-Net 4500 Border Gateway (BG) is a decomposed SBC element for IMS networks that controls the media flows within SIP signaled sessions. It is controlled by a master P-CSCF, SPDF or I-BCF using the H.248 Ia interface. The Net-Net BG controls the transport network boundary at layers 3 and 4 between the service provider core network and the its access or interconnect networks. It acts as a pinhole firewall and NAT device protecting the service provider IMS core. It controls access by packet filtering on IP address/port and opening/closing gates (pinholes) into the network. It uses Network Address and Port Translations (NAPT) to hide the IP addresses/ports of the media elements in the IMS core. QoS packet marking, bandwidth policing, usage metering and QoS measurements for the media flows are additional features supported by the Net-Net 4500 BG.

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 IMS, RCS, FMC or NGN service; any SIP application—voice, video, presence, messaging and multimedia; over any mobile or fixed line 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.

The Net-Net 4500 Security Gateway (SG), a multiservice security gateway (MSG), enables fixed-mobile substitution (FMS) and convergence (FMC) by securing the delivery of voice and data services over untrusted Internet and WiFi networks to femtocells and dual-mode endpoints. The Net-Net 4500 SG securely connects subscribers to their mobile voice and data services over the untrusted Internet and/or untrusted wireless networks using IPsec tunnels. It is deployed at the border between the core mobile services network and the untrusted wired Internet and/or wireless networks that use public, unlicensed spectrum such as WiFi. The Net-Net 4500 SG is truly “multiservice” supporting both SIP and UMA voice services and all data services. Its security function authenticates mobile endpoints, secures the voice and data traffic within IPsec tunnels to ensure privacy and protect against theft, and defends against DoS/DDoS attacks on the mobile service infrastructure at the TCP/IP and IPsec networking levels to deliver non-stop service. In SIP deployments, the SG functions may be added to the Net-Net 4500 SD configuration, optimizing overall performance and minimizing cost. Read more about the capabilities and advantages of the Net-Net 4500 SG on our multiservice security gateway page.
The Net-Net Diameter Director, a Diameter signaling controller (DSC), addresses critical congestion control, interoperability, routing and scaling challenges in next generation Long Term Evolution (LTE) and IP Multimedia Subsystem (IMS) networks. The Net-Net Diameter Director enables the exchange of critical subscriber information based on Diameter signaling within service provider networks or across LTE IP network borders.
The Net-Net Diameter Director is a Diameter agent that provides an intermediary control function for Diameter transactions and sessions. These control functions— congestion control, mediation and routing functions—for Diameter signaling enable the seamless communication subscriber data and reduces the mesh of Diameter connections that negatively impacts network performance, capacity and management.
The Net-Net Diameter Director leverages Acme Packet’s Net-Net OS software to offer industry-leading DSC security and control functions for Diameter signaling, performance, carrier-class availability and manageability. These functions reduce costs, streamline networks and assure availability for LTE and IMS networks.

The Net-Net 4500 Session Router (SR) is a session routing proxy that consolidates and simplifies the routing of SIP-based voice, video, instant messaging and multimedia sessions within-and-between mobile, fixed line and transit networks, helping service providers reduce capital and operating expenditures while optimizing service revenue. In Acme Packet’s Open Session Routing Architecture (OSR), the Net-Net 4500 SRP works in conjunction with best-of breed routing database products and services from Acme Packet partners. These complementary product vendors and service providers offer centralized routing databases and database provisioning tools for dynamic route selection. The Net-Net 4500 SRP queries these databases using industry-standard ENUM, SIP and DNS protocols. The Net-Net 4500 SRP’s local route tables can also be provisioned by our Net-Net Route Manager Central (RMC). The Net-Net 4500 SRP dynamically routes sessions between all types of borders, including access and interconnects, IP and TDM. More specifically, it routes sessions between stateful service control elements such as session border controllers, Mobile Switching Centers (MSC), IMS subscriber call control elements and softswitches controlling media gateways. Since the source and destination SIP signaling elements are session-stateful, an SRP can operate in a transaction-stateful mode, maximizing routing performance. The SRP can also operate in session-stateful mode when protocol normalization, accounting or other stateful functions are required. Read more about the capabilities and advantages of the Net-Net 4500 SR on our session routing proxy page.
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.
