Patent number: 10075391Abstract: A method for allocating port assignments for transmitting a reserved network stream across a network node comprises determining a cycle time associated with a network node. The method also comprises establishing, for at least one port of the network node, a plurality of virtual layers associated with the cycle time, wherein each of the plurality of virtual layers is divided into 2n equally-spaced slots per cycle (where n>0). The method further comprises receiving a reserved stream request associated with transmission of a reserved stream across the node, and determining a number of slots required to transmit the reserved stream. The method also comprises assigning one or more slots associated with a port of the network node to the transmission of packets associated with the reserved stream based on the determined number of slots. The method further comprises transmitting the stream according to the slot assignment associated with the port of the network node.Type: GrantFiled: August 28, 2017Date of Patent: September 11, 2018Assignee: Cisco Technology, Inc.Inventors: Norman William Finn, Rong Pan, Hiroshi Suzuki, Linda Tin-Wen Cheng, Peter Geoffrey Jones, Hariprasada Rao Ginjpalli, Rudolph Benedict Klecka

Patent number: 9226292Abstract: One embodiment includes: forwarding a particular packet through an Available Routing Construct (ARC) chain topology network. In one embodiment, this forwarding includes: sending the particular packet by each particular non-edge node on an arc of the plurality of arcs receiving the particular packet to each sibling on the arc that did not send the particular packet to said particular non-edge node, while not sending the particular packet if it was received from both siblings of said particular edge node; and sending the particular packet to a respective child node on a second arc of the plurality of arcs by each particular edge node of two edge nodes on the arc after receiving the particular packet. In one embodiment, the network is a wireless deterministic network with pre-assigned time slots for receiving and subsequently sending a same particular packet by each node of the network.Type: GrantFiled: September 9, 2013Date of Patent: December 29, 2015Assignee: Cisco Technology, Inc.Inventors: Pascal Thubert, Norman William Finn, Jean-Philippe Vasseur, Patrick Wetterwald

Patent number: 6049834Abstract: A process for the reliable distribution of a shortcut table for layer 3 switching is distributed from a plurality of routers to a plurality of switches includes the transmission by the router of a list of shortcut entries, which includes a list of switches which have acknowledged receipt of this list of shortcut entries. The transmission of these database messages continues until all target switches have acknowledged receipt of the database messages. The interval between transmission of database messages is short until all switches have acknowledged reception of such database messages, and thereafter the interval between transmissions is lengthened, and a hello message is sent until a new switch is added to the network, or a change in router shortcut database occurs, whereafter the transmission of database messages is resumed utilizing the interval between these transmissions is again shortened until all such messages have been acknowledged.Type: GrantFiled: May 8, 1998Date of Patent: April 11, 2000Assignee: Cisco Technology, Inc.Inventors: Percy Khabardar, Norman William Finn
