To address this, we will add a function when selecting VNF instance in second VNFFG to exclude the selected VNF instance in first VNFFG from the VNF instance set if possible. Then, two VNFFGs will be disjointed as much as possible. To do this, we think adding a new api in tacker-client is better solution.","commit_id":"2954876772cba6a5a5c56a50e259dceca0ae3eb5"},{"author":{"_account_id":26588,"name":"Hiroyuki Jo","email":"joxyuki@gmail.com","username":"joxyuki"},"change_message_id":"4fd139d5680a871e1e5dea095be538634d40e5f3","unresolved":false,"context_lines":[{"line_number":40,"context_line":""},{"line_number":41,"context_line":"The method we are going to implement is as follows."},{"line_number":42,"context_line":""},{"line_number":43,"context_line":"We will modify the tacker-client code to add the redundancy module option."},{"line_number":44,"context_line":""},{"line_number":45,"context_line":"In the process of creating the second VNFFG, we will add a procedure to avoid selecting the vnf inst"},{"line_number":46,"context_line":"ance previsouly selected."}],"source_content_type":"application/octet-stream","patch_set":12,"id":"3fa7e38b_d04742a4","line":43,"range":{"start_line":43,"start_character":14,"end_line":43,"end_character":74},"in_reply_to":"3fa7e38b_cdc7c166","updated":"2020-01-31 07:41:37.000000000","message":"IMO, it\u0027s better to have a new parameter indicating redundant VNFFG in VNFFGD like VDU anti-affinity policy [1].

Therefore, when we create the multiple VNFFGs with the same VNFFGD, same VNF instances can be chosen in high probability. \n\nFor example, There are 4 VNF instances (VNF1, VNF1\u0027, VNF2, VNF2\u0027) and two instances (VNF1, VNF1\u0027)  are made from VNFD 1 and the other two VNF instances (VNF2, VNF2\u0027) are created from VNFD2.
