20090185551 | Method and system for providing confirmed delivery of ethernet packets - Methods and systems are disclosed for providing confirmed delivery of Ethernet packets. The type/length (T/L) field of the standard Ethernet protocol packet is used to provide sequence numbers for guaranteed delivery of Ethernet packets. Sequence numbers are assigned at a transmitting device and read by a receiving device to confirm delivery of the Ethernet packets. If a missing packet is detected by the receiving device, it requests retransmission of the missing packet. Because the T/L field has limited use in legacy Ethernet systems, this use of the T/L field for guaranteed delivery has little, if any, effect on legacy systems. | 07-23-2009 |

A method includes directing a communication from an information handling system to a first port when the communication has a target address that is less than the address of the information handling system or to a second port when the communication has a target address that is greater than the address of the information handling system. | 11-26-2009 |
20090316574 | PATH MAXIMUM TRANSMISSION UNIT DETERMINATION - Disclosed are techniques for determining a path maximum transmission unit (MTU) of a communication path connecting two or more nodes of a network. A node initiates a connection with a remote node by repeatedly transmitting increasingly-larger path MTU discovery messages until the size of a path MTU discovery message exceeds the link MTU of a link within the communication path. This results in the generation and transmission of an MTU error message back to the initiating node. The edge router linked to the initiating node generates a MTU change message in response to receiving the MTU error message and multicasts the MTU change message to all local nodes to which it is linked. The MTU change message directs the receiving nodes to update their destination caches to reflect the path MTU discovered through the use of the increasing-size path MTU discovery messages and the resulting MTU error message. | 12-24-2009 |

20100121947 | System and Method for Managing the Offload Type for Offload Protocol Processing - A method for determining the offload type for the processing of the protocol of a network connection is disclosed. An offload policy manager in a server node determines the offload type on the basis of a number of factors, including the application type of the network connection, the traffic priority of the network connection, and the port of the network connection. After the offload policy manager selects the offload type of the network connection, the offload policy manager identifies the offload type to the offload engine, which processes the protocol of the network connection according to the offload type selected by the offload policy manager. The offload policy manager is able to access a number of application-specific tables. The offload policy manager selects an offload type by cross-referencing on an application-specific table the traffic priority of the network connection against the port of the network connection. | 05-13-2010 |
