摘要： A Converged Enhanced Ethernet network may include a controller having a computer processor connected to a layer 2 endpoint buffer. A manager executing on the controller monitors the layer 2 endpoint buffer by determining buffer data packet occupancy and/or rate of change in the buffer data packet occupancy. A reporter notifies a congestion source of the layer 2 endpoint buffer based upon the buffer data packet occupancy and/or rate of change in the buffer data packet occupancy.

摘要： A method of performing congestion management in a network includes monitoring a congestion status at a switch in the network. It is determined at the switch that the congestion status indicates that there is congestion at the switch. Based on the congestion being related to data received at the switch from a source at a first rate, a first message is transmitted from the switch to the source requesting the source to send the data at a second rate that is slower than the first rate. Based on the congestion being related to data requests received at the switch from a destination at third rate, a second message is transmitted from the switch to the destination requesting the destination to request the data at a fourth rate slower than the third rate.

摘要： An aspect includes dynamic port type detection. A link initialization frame that includes a protocol identifier is received at a port of a switch. Based on successfully decoding the protocol identifier, the port is configured to a mode of operation compatible with the protocol identifier. A table in the switch is updated to configure one or more other ports of the switch to the mode of operation compatible with the protocol identifier. A handshake response is sent to acknowledge the successful decoding of the protocol identifier. If no handshake response is received at a server prior to expiration of a wait pulse repetition time, the server periodically transmits the link initialization frame with a different protocol identifier for an alternate mode of operation until the handshake response is received or all supported modes of operation are checked.
