     - add EC and FC result together for feedback
 - FC: AIMD for fairness

+- very good performance in simulation
+    - few drop
+    - high throughput, fast convergence
+        - TCP probe slowly, expensive drop
+    - low delay
+- cannot deploy: firewall, modify router & kernel
+- use case: (between) data center, satellite, CDN/WAN
+    - doable in software-defined network (SDN)

+## *Directed Diffusion: A Scalable and Robust Communication Paradigm for Sensor Networks*, Chalermek Intanagonwiwat, Ramesh Govindan, Deborah Estrin
+
+- wireless/mobile network tricky
+    - device move
+    - bit rate & bandwidth change
+    - less capacity
+    - difficult security, jamming
+    - different MAC protocol
+    - power constraint
+- sensor network: cheap & numerous—how to communicate
+- protocol for sensor network
+    - peer-to-peer: no IP address, use attribute/ named data
+    - where to send: interest, gradient → flood/multicast
+        - respond w/ data if we have
+        - reinforcement: become faster by sending via preferred path
+    - process in the network: reduce traffic, save energy (battery)
+- compared to BGP: smaller scale, more dynamic, on-demand (not ahead of time)
