Redundancy Support

Read this topic to learn about the redundancy options available in the CSDS Architecture.

The CSDS Architecture supports redundancy in the forwarding layer and the services layer.

  • Forwarding layer redundancy uses equal-cost multipath (ECMP)-based Consistent Hashing or CSDS Traffic Orchestrator (CSDS-TO) on MX Series routers for load balancing and service redundancy daemon (SRD) for redundancy between two MX Series routers.
  • Services layer uses Multinode High Availability (MNHA) on SRX Series Firewalls.

See Understanding ECMP Groups for more details on ECMP based Consistent Hashing.

See How Does CSDS Traffic Orchestrator Work for more details on CSDS-TO.
