Abstract
An apparatus, system, and method are disclosed for handling data being communicated over lossless Ethernet that is sensitive to delays. Fiber Channel over Ethernet (FCoE) is one example of an environment where data may be subject to unacceptable delays. The method involves designating certain data as low latency data that is sensitive to delays in transmission. The low latency data is then transmitted in such a manner that the receiving devices are aware that they are receiving low latency data. If a delay in the transmission of low latency is detected, commands are issued that pause or slow standard data in order to free up bandwidth for the low latency data. The commands may be, for example, backward congestion notifications and priority flow control. Low latency data is exempted from backward congestion notifications and priority flow control. Priority 7 priority group 15 may be reserved exclusively for low latency data.
