We have network where we are usng ZTE T-1200 routers at A and T 600 Router at B location. We have rescently used Destination based routing between A and B. 4 STM-1s are thre between A and B.
Now the % utilization of the STM-1s are 91%, 89%, 12 % and 9%. Kindly suggest would this be safe for the router taking the utilization upto so high.

We are currently building HA application with active-active mode and would like to deploy load balancer to load balance the traffic. The connection between client and HA hosts are persistent, that means client only establish one session to the virtual IP of the load balancer and we expect load balancer to load balance the packet from client to destination host. Does it fit into per-packet load balancing definition? Thanks
