Hi
I have grid topology of 4 nodes
h1----s1------s2----h2
| |
h3----s3------s4-----h4
I am using networkx for getting graph of the network and using shortest
path for path calculation.
Suppose I am sending traffic from h1 to h4. The shortest path is being
calculated s1-s2-s4 and all packets follow this path.
After some times link s1-s2 gone down and I want to send traffic through
s1-s3-s4.
For doing this I have updated the graph when topology has been changed and
using EventOFPPortStatus I could able to delete flow rules from s1 and s2
means link that affects the nodes.
But how can I delete flow entry from node s4 also?
That means not only delete flow rules from the affected nodes but also from
affected path.
Any suggestion would be appreciable.
