Hello everyone, I want to use Traffic controller to set socket priority to use 16 different priority queues, but TOS only got four fixed value, which means I can only set 5 priority. Here is the value from ip.h. #define IPTOS_LOWDELAY 0x10 #define IPTOS_THROUGHPUT 0x08 #define IPTOS_RELIABILITY 0x04 #define IPTOS_MINCOST 0x02 My question is: Can I use these combination value, i.e. 0x18, 0x14? I heard routers did not respect these value regarding to routing packet. I read source code ip_sockglue.c, it seems ok to use combination value. Is there any side effect to do that?
