Overlay multicasting providing live streaming\nservices became crucial service in contemporary Internet. In\nthis paper, we focus on applying the overlay multicasting for\ndelivering of critical data that require to be transmitted safely,\nintact and with as little delay as possible. To improve survivability\nof the overlay multicasting, we propose to use dual\nhoming approach, i.e., each peer is connected to the overlay\nby two separate access links. We consider the following\nnetwork failures: overlay link failure, uploading node failure\nand ISP interconnection failure. The main goal of our\nexperiments is to determine the additional cost of providing\nsurvivability to the overlay multicasting network with dual\nhoming technology for both flow assignment and capacity\nand flow assignment problems. Our studies indicate that the\nadditional survivability requirements do not have a substantial\nimpact on the overlay multicasting system expressed as\nstreaming cost or network cost.
