Abstract: Methods and systems for improved pathway decision forwarding for rack domains include a gravity well forwarding protocol that enables local forwarding decisions at each network node involved with forwarding packets. The gravity well forwarding protocol may administer gravity well values for each of a plurality of rack domain nodes in a rack domain. The local forwarding decisions may involve selecting output ports corresponding to a higher/lower gravity well value at a network switching element, depending on a destination gravity well value associated with a network packet. Assignment of the gravity well values among the rack domain nodes may be used according to considerations, including security considerations, throughput considerations, loading considerations, redundancy considerations, physical location, and/or physical proximity, among other considerations, in the rack domain.

Abstract: A network communication pause system includes a network interface device and a management controller. The management controller is operable to monitor first data traffic that is received by the network interface device over a network and that is associated with a sender Media Access Control (MAC) address and a receiver MAC address. If the management controller determines that the first data traffic has exceeded a threshold, a pause frame that includes the sender MAC address is sent over the network through the network interface device to a sender device associated with the sender MAC address. The pause frame may include an operations code that causes intermediate devices coupled between the management controller and the sender device to forward the pause frame to the sender device, and a pause time for which the sender device will pause the sending of data traffic to the receiver MAC address.

In one form, a method of altering communication rates within a communication network can include monitoring a data rate of a first communication link within a network, and detecting a congestion of a first end point coupled to the first communication link. The method can also include identifying the first end point, and determining a desired data rate of the first communication link to effect the congestion. The method can further include communicating at least one null packet to the first end point to alter the data rate of the first communication link at the first end point.

Abstract: 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.
