Katran is a C++ library and BPF program for building a high-performance layer 4 load balancing forwarding plane. It leverages the Linux kernel's XDP infrastructure for fast in-kernel packet processing.
Use cases
- build a high-performance layer 4 load balancer
- scale out layer 7 load balancers with an L4 forwarding plane
- process packets in-kernel with XDP for maximum throughput
- replace DNS or anycast-based traffic distribution with an L4 LB
- distribute traffic across backend servers at line rate
When to choose
- you need blazing-fast L4 load balancing that scales linearly with NIC RX queues
- you run a recent Linux kernel and can deploy XDP/eBPF-based networking
- you want a programmable forwarding plane with gRPC or Thrift control endpoints
When to avoid
- you need a layer 7 load balancer that terminates TCP/TLS sessions
- you need a solution that runs on non-Linux platforms or older kernels
- you want a turnkey appliance rather than a library to integrate
