Company A has 2 remote sites and an HQ. The media is Multiaccess. The sites are connected all on the same subnet using metro ethernet. The connection to the main site is 1 gig while the other sites are 10 meg. A video conference between remote site A and B is having poor quality because a user from site B is downloading a large file off a server from the HQ at the same time at 7 mb's. What can be done to give video conferencing QOS if the metro ethernet providers network is best effort? Some video conferencing also occurs between the HQ and remote sites.
