Our Net-Net Session-aware Load Balancer (SLB) enables linear, non-disruptive session border control (SBC) capacity, scaling to two million subscribers from a single SIP IP address.
Net-Net SLB supports the delivery of:
- any IP Multimedia Subsystem (IMS) or NGN service, or
- any SIP application — voice, video, presence, messaging or multimedia—over
- any fixed-line or mobile access network, including the Internet
Creating the Net-Net Cluster
Net-Net 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 along with subscriber capacity, load and session state.
Like all Net-Net solutions, 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.
Net-Net SLB is deployed with our Net-Net Session Director SBCs to create a Net-Net Cluster. The cluster, in turn, consists of two or more Net-Net SBCs front-ended by Net-Net SLB for SIP signaling.
The Net-Net Cluster scales subscriber capacity without requiring architectural forklifts or network disruptions. All cluster elements are SIP-subscriber and session-aware. As a result, it beats out traditional layer 3/layer 5 web load balancers and SIP redirect servers on scalability, dynamic adaptive load balancing, redundancy and centralized management.
