BalanceNG is a software load balancer for Linux from Inlab Networks GmbH. It uses its own IPv4/IPv6 stack, a multithreaded architecture, active/passive clustering based on VRRP and the bngsync session-table synchronisation protocol. It also includes an in-memory location database for IPv4 and IPv6. It is aimed at network operators, satellite operators, hosting companies and telecom product designers. The software is installed by the customer on Linux; knowledge-base articles cover virtualised environments such as VMware and KVM. A related, separate tool called Balance is open source; BalanceNG itself is supplied with licence keys.
Inlab Networks GmbH is a German company and states that BalanceNG carries the TeleTrusT 'IT Security made in Germany' quality mark. Because the product runs as software on the customer's own systems, traffic and configuration stay under the customer's control and no data processing at the vendor is required. The website names no owner and no foreign parent company.
