  1. Double capacity butterfly network test case

As shown in Figure 21., the source node is acting as a coding node. Coded data block “a+b” is then multicast by node 3 and received by sink node 5 and node 6. Both sink nodes could decode it with another single data block “a” or “b”.



  1. Coding at source node test case

As shown in Figure 22., the coded data block might be coded again. The coded data block a+b is coded to a+b+b at node 7. Actually, a+b+b is equals to a. Node 9 could decode a+b with a and node 10 receives both a and b.
