Key Features

Self-sufficient and lightweight: BalanceNG operates independently without relying on third-party packages or kernel modules, providing flexibility for network operators, satellite operators, hosting companies, and Telco product designers.

Handles massive numbers of concurrent sessions with ease: BalanceNG efficiently manages large numbers of concurrent sessions, allowing for seamless scalability and high performance.

Multithreaded packet processing by design: BalanceNG's multithreaded packet processing engine is designed to handle increasing traffic and bandwidth demands, aiming to saturate a 10GbE connection on suitable hardware.

Ready for the future of Linux: BalanceNG stays up-to-date with modern Linux distributions like Fedora, ensuring readiness for upcoming LTS and production RHEL releases. It is considered "RHEL10-ready."

Specialized minimal IP protocol stack from Layer 2: BalanceNG handles packet processing independently, covering essential protocols such as IPv4, IPv6, ARP, ND6, TCP, UDP, VRRP2, VRRP3, etc., reducing dependence on the Linux IP stack.

Full IPv6 support: BalanceNG provides comprehensive support for both IPv4 and IPv6, enabling organizations to seamlessly transition to IPv6 and ensuring compatibility with modern networking technologies.

Backup targets in case of failure: BalanceNG allows for the specification of backup targets to ensure high availability and continuous service, even in the event of primary target failures.

Layer 4 IP persistence: BalanceNG supports Layer 4 IP persistence, aiming to direct subsequent requests from the same client to the same server, enhancing user experience and session continuity.

Session table state replication: BalanceNG supports session table state replication between VRRP master and backup, ensuring seamless failover without interrupting open TCP connections and maintaining session table synchronization.

DNS-based GSLB (Global Server Load-Balancing): BalanceNG supports DNS-based Global Server Load-Balancing, enabling the distribution of traffic across geographically distributed servers based on DNS responses, improving performance and availability.
