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 |
20100091684 | System and Method for Discovery of Dynamically Assigned Information Handling System IP Addresses - A network manager tracks network nodes in an IPv6 network by identifying server nodes that dynamically-assign network addresses, such as DHCP server nodes, retrieving prefix information from the DHCP server nodes, and querying a range of network addresses determined from application of the prefix information to identify client nodes of each DHCP server node. In one embodiment, the prefix information comprises a start prefix value that identifies the starting address of the range and a prefix length value that determines the number of addresses in the range. For example, the network manager sends echo messages to each address in the range by starting at an address determined from the start prefix value and incrementing the network address for a number of increments equal to at least the prefix length value. | 04-15-2010 |

Packets having destination address that match a host information handling system or management controller network address are redirected from communication across the network to communicate directly between the host information handling system and management controller. | 08-18-2011 |
