摘要： A system and method for communicating over a single virtual channel. The method includes reserving a first group of credits of a credit pool for a first traffic class and a second group of credits of the credit pool for a second traffic class. In addition, a first and second respective groups of tags are reserved from a tag pool for the first and second traffic class. A packet may then be selected from a first buffer for transmission over the virtual channel. The packet may include a traffic indicator of the first traffic class operable to allow the packet to pass a packet of the second traffic class from a second buffer. The method further includes sending the packet over the virtual channel and adjusting the first group of credits and the first group of tags based on having sent a packet of the first traffic class.

摘要： Methods and apparatus for peer-to-peer data transfers in a computing environment provide configurable control over the number of outstanding read requests by one peer device to another. A requesting peer device includes a control register that stores a high-watermark value associated with requests to a target peer device. Each time a read request to the target peer device is generated, the number of such requests already outstanding is compared to the high-water mark. The request is blocked if the number of outstanding requests exceeds the high-water mark and remains blocked until such time as the number of outstanding requests no longer exceeds the high-water mark. Different high-water marks can be associated with different combinations of requesting and target devices.
