When I am at home (comcast internet infrastructure), the packets go to either the att backbone router or the greatoaks.ca router and then cross the ocean to China CNC backbone router (219.158/16). This path is extremely slow due to high latency and high packet loss (almost >80% all the time).
When I am at office, the packets go to the sprintlink.net backbone (144.232/16) and cross the ocean to the sprintlink.net backbone that hosted in china (sl-chinaXX) and then routed to the China CNC backbone router (219.158/16). Since the across-ocean lane is all within the Sprintlink network, the quality is much much better (much lower latency and packet loss).
Now I am wondering if it is possible for me to do anything to let the packets egressing from my home network (comcast) to use the sprintlink BB router path? Would adding route path rules in my home router work? If not, do I have any other choices to improve the network quality at home?
