About modifying flow in openflow 1.0 and 1.3 versions

[chaitrashree]

I have installed controller of version 2.4.5 and trying to get response for the Rest apis from java.

It is working fine with the POST, GET AND DELETE commands for the flow in 1.0 and 1.3.

1.But,in modifying the flow the passing the same json with some modification like change in protocol or src dest ips

But it is not modifying the existing the flow rather it is adding  the another flow in the specified switch.

2. After flow creation no ping is happening in the mininet prompt but same count of packet loss is getting added to the packet count for the particular flow.(for iCMP and TCP)

3.Ping is happening but no updation in byte and packet count for UDP protocol.

Hoping for the solution and Thank you in advance.

The have attached the sample for reference.
