+  categoryDescription: |
+    Pod-network-duplication contains chaos to disrupt network connectivity to kubernetes pods. Experiments can inject percentage packet duplication on the app replica pods. 
+    - Causes lossy access to application replica by injecting packet duplication using pumba.
+    - The application pod should be healthy once chaos is stopped. Service-requests should be served (say, via alternate replicas) despite chaos.
