Patent number: 10044593Abstract: A system is provided for controlling the flow of data-packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links. Incoming data-packet traffic from multiple customer connections are received at a first node for entry into the network via the first node. Flow control messages are generated to represent the states of the first node and, optionally, one or more network nodes upstream from the first node, and these states are used as factors in controlling the rate at which the incoming packets are admitted to the network. Alternatively, the flow control messages may be used to control the rate at which packets generated by a client application are transmitted to the first node.Type: GrantFiled: February 27, 2017Date of Patent: August 7, 2018Assignee: Ciena CorporationInventors: Natalie Giroux, Ken Young, Brian Smith, Chris Barrett, Pablo Frank

Patent number: 8509062Abstract: A telecommunications system includes a network for transporting packets on a path between selected subscriber end points. The network has multiple nodes connected by links, with each node (a) pairing the forward and backward paths of a connection and (b) allowing for the injection of messages in the backward direction of a connection from any node in the path without needing to consult a higher OSI layer. A system is also provided for protecting connection paths for transporting data packets through an Ethernet telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. Primary and backup paths are provided through the network for each of multiple connections, with each path including multiple links.Type: GrantFiled: August 7, 2006Date of Patent: August 13, 2013Assignee: Ciena CorporationInventors: Jim Arseneault, Chris Barrett, Pablo Frank, Brian Smith

Patent number: 8363545Abstract: A method of controlling the flow of data packet traffic from a first point to at least two second point in an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises monitoring the level of utilization of a link between the first and second points, generating flow control messages representing the level of utilization and transmitting the control messages to the first point, and using the states represented in the flow control messages as factors in controlling the rate at which the packets are transmitted from the first point to the second point.Type: GrantFiled: February 15, 2007Date of Patent: January 29, 2013Assignee: Ciena CorporationInventors: Ken Young, Pablo Frank, Chris Barrett, Brian Smith, Natalie Giroux

Patent number: 8218445Abstract: A system is provided for selecting connection paths in a telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. The system identifies multiple constraints for connection paths through the network between source and destination nodes, and identifies paths that satisfy all of the constraints for a connection path between a selected source node and a selected destination node.Type: GrantFiled: June 2, 2006Date of Patent: July 10, 2012Assignee: Ciena CorporationInventors: Fabio Katz, Pablo Frank, Brian Smith

Patent number: 8139485Abstract: A method for managing data packets passing through an Ethernet node having multiple ingress ports and multiple egress ports, the ingress ports receiving the data packets from at least one service, and the egress ports configured with at least one Logical Transport Resource (LTR) configured as a predefined path between one of the egress ports and a destination in the Ethernet network. The method comprises mapping one or more of the services to each of the at least one LTR, shaping each of the at least one LTR to a configured rate, and transmitting data packets to the Ethernet network via the egress ports.Type: GrantFiled: January 22, 2009Date of Patent: March 20, 2012Assignee: Ciena CorporationInventors: James D. Arseneault, Chris Barrett, Allan Beaudette, Nicholas J. Cadwgan, Pablo Frank, Natalie Giroux, Frederic Perras, Brian R. Smith, Kenneth W. Young
