Does anyone have suggestions of software or ideas on managing cloud services aka DropBox, ICloud, etc. We support 15 locations that all have their own individual T1. When users are sharing large amounts of data it cripples other users on the network. Rather than throwing bandwidth at the problem we are looking for other possibilities. We are a Cisco company, and QOS is setup managing routers at each location. These services communicate through port 80 which makes it difficult to filter.
