Our edge

Low-cost, integrated, single system delivery solution

Acme Packet’s Net-Net SMX builds upon the Net-Net 4500 Session Director (SD) access SBC which already incorporates multiple IMS functions—P-CSCF, E-CSCF, IMS-AGW—as well as an industry-leading SIP signaling firewall function. Net-Net SMX adds SIP Registrar and core session control capabilities, and interfaces with a wide range of options  including:

  • Interface to ENUM-based or HSS (Cx) subscriber database for authentication, authorization, location update and lookup
  • PCRF and RACS interfaces (Rx)
  • NASS/CLF interface (e2)
  • Standard interfaces to I-BCF (Mx), AS (ISC), BGCF (Mi), MGCF (Mj/Mg) elements
  • Optional I-BCF, IWF and TrGW for interconnect/peering
  • Optional BGCF for core session routing

This solution reduces the cost of RCS and IMS-equivalent service delivery infrastructure to approximately $2–3 per subscriber for as few as 100,000 subscribers.

Cost-effective, scalable solution

A Net-Net SMX solution can easily evolve to support larger scale IMS/RCS deployments by creating a SMX SBC cluster using the Net-Net Session-aware Load Balancer (SLB) to increase subscriber capacity, adding the Net-Net Session Router to off-load core session routing or adding Net-Net Session Director(s) to increase interconnect/peering capacity.


SMX

Net-Net SMX can also evolve to a fully-compliant, decomposed IMS architecture. The Net-Net SMX SBC would remain at the IMS access border providing full access SBC functions and new dedicated I-CSCF and S-CSCF elements could be deployed.

Flexible subscriber database options—HSS, ENUM server or local subscriber table

Net-Net SMX supports three centralized subscriber database deployment options–two external and also a local on-board subscriber table.  Using the Cx Diameter interface on Net-Net SMX, Home Subscriber Server (HSS) elements can be queried for authentication, authorization, location update and lookup. As an alternative to a HSS, Net-Net SMX supports an interface to an ENUM-based server database for both subscriber and routing information. Similar to Acme Packet’s local routing table, Net-Net SMX also can provide a local subscriber table for subscriber credentials. The multitude of options provides flexibility for service providers looking to balance cost, performance and migration preferences.

Industry-leading Net-Net OS SBC functions & features including Net-SAFE security

Based on the on the industry-leading Acme Packet Net-Net OS, the Net-Net SMX solution supports all SIP session control functions and features in the areas of security, service reach maximization, SLA assurance, revenue protection and regulatory compliance. Net-Net SMX is a complete access SBC providing IMS compliant P-CSCF, E-CSCF, and IMS-AGW functions.
