SBC configurations

Acme Packet SBCs can be configured with signaling and media control integrated in a single system (integrated SBC) or with signaling and media control divided across separate systems (decomposed SBC). Acme Packet offers the following SBC configurations:

  • Net-Net Session Director (SD)—integrated SBC with SIP signaling and media control
  • Net-Net Border Gateway (BG)—decomposed SBC with media control only, uses H.248 control interface to master third-party SIP signaling element
  • Net-Net Signaling Firewall (SF)—decomposed SBC with SIP signaling security and other control functions

Net-Net SDs support many IMS functions. Access SBC functions include P-CSCF, E-CSCF, I/S-CSCF-equivalent functions via Net-Net SMX, signaling firewall (SF) and IMS-AGW. ATCF and ATGW functions, as part of the access SBC, provide seamless call continuity and call handover between LTE and circuit mobile networks. The BGCF for core session routing can also be incorporated into a single SBC system. Interconnect SBC functions include I-BCF, IWF and I-BGF/TrGW.

Net-Net SIP Multimedia-Xpress (SMX) combines core session control with leading session border control functions to reduce the complexity and cost of delivering high-value, revenue generating SIP multimedia services. Net-Net SMX can be used to deliver a broad range of SIP services including residential or business voice, Rich Communication Suite (RCS) services and fixed mobile convergence (FMC) for small subscriber populations or initial service rollouts. Net-Net SMX provides an alternative to an expensive, fully decomposed IMS infrastructure yet also provides an evolutionary path to IMS compliant architectures.

Net-Net Session-aware Load Balancer (SLB) is used with Net-Net Session Directors to create a Net-Net Cluster. A Net-Net Cluster enables linear, non-disruptive 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.
