  • It acceptable multiple delivery paths.

Disadvantages of DHT with a mesh overlay topology:

  • This is complex structure to develop.
  • This process is required to resources more for difficult delivery scheme.

Advantages of Circular DTH(with no shortcuts):

  • It contains only two peers, one is predecessor and second is successor.

Disadvantages of Circular DTH(with no shortcuts):
