Abstract:
1. A method comprising: for each of a plurality of media access control (MAC) devices to which data is to be transmitted over a ring topology network, providing a corresponding queue, wherein each corresponding queue is configured to transmit data in a first egress direction and a second egress direction over the ring topology network; receiving data, from a local client, destined for a client of a first MAC device of the plurality of MAC devices; storing at least a portion of the data in a first queue corresponding to the first MAC device; receiving information generated by the client of the first MAC device indicating a need to change an amount of data being transmitted to the client of the first MAC device, wherein the information is generated by the client of the first MAC device in response to the client of the first MAC device determining that the client of the first MAC device is receiving data at a rate exceeding a set threshold; receiving information indicating a bandwidth limitation for each link of the ring topology network between the local client and the first MAC device; and selectively transmitting data stored in the first queue to the first MAC device, wherein
