[Nfd-dev] smart flooding strategy

[Lan Wang (lanwang)]

Junxiao,

Can I use the access router strategy (http://redmine.named-data.net/issues/1999) at every node (not just the access router) to implement essentially smart flooding?  Basically, I want the following strategy: 

1. The first time an Interest is received, the Interest will be sent to all the faces of the node except the incoming face.  

2. When the matching Data packet comes back, the face that brings back the data will be remembered.

3. subsequent Interests to this face will use the remembered face.

4. If no Data comes back, send subsequent Interests to all faces.

Since you implemented the access router strategy, I'm wondering if you think there's any potential problems with this.  Also in your design, you exclude the last working nexthop.  I'm not sure if this is necessary (it doesn't hurt to try it again).
