1. A method of establishing a data transfer rate between network endpoints, the method comprising:
initiating a connection between a first endpoint of a first network and a second endpoint of a second network, wherein the connection between the endpoint of the first network and the endpoint of the second network can transfer data at up to a first transfer rate;
determining the first transfer rate is greater than a second transfer rate for transferring data over the second network; and
transmitting, in response to determining the first transfer rate is greater than the second transfer rate, a configuration message to a network device corresponding to the first endpoint, wherein the configuration message causes the network device to limit transfer of data over the connection from the first endpoint to the second endpoint to no greater than the second transfer rate, wherein
the second network includes two or more third endpoints connected to a respective sub-interface of the second endpoint and enabling a respective transfer rate therebetween,
the second transfer rate is a sum of transfer rates between the second network device and the two or more third endpoints, the first network device transferring data to each of the two or more third endpoints over respective virtual channels, and
the configuration message limits data transfer over each of the virtual channels to the lowest transfer rate of the transfer rates between the second network device and each of the two or more third endpoints.
