Patent number: 7826345Abstract: Each span of a communication network, such as a BLSR ring, is assigned a unique span ID. When a node of the network detects a failure in a network span, the node exchanges commands, according to an automatic protection switching (APS) protocol, that request other nodes of the network to switch network traffic from a working span to a protect span. The commands specify the working span by its span ID, without necessarily specifying a source node ID or a destination node ID for the commands. The span ID occupies fewer bits in the commands than bits representing a combination of the source node ID and the destination node ID. Alternatively, the commands specify a destination node ID without a span ID or a source node ID, or the commands specify a source node ID without a span ID or a destination node ID.Type: GrantFiled: July 7, 2004Date of Patent: November 2, 2010Assignee: Sycamore Networks, Inc.Inventors: Anthony C. K. Kam, Raymond Y. Xie, Tao Yang, Naimish Patel

Publication number: 20050041601Abstract: A shared protect link extends between adjacent nodes that are shared by two or more adjacent BLSR rings. The shared protect link obviates the need for separate protect links between the adjacent nodes for each of the rings. A composite BLSR controller resides in each of the adjacent nodes. The composite BLSR controllers coordinate usage of the shared protect link, for example as a result of a span switch or a ring switch request. The composite BLSR controllers also coordinate transmission of signaling information for each of the rings over the common span between the adjacent nodes. In one embodiment, the signaling information is sent over separate channels of the common span. In another embodiment, the signaling information is multiplexed over the shared protect link. Each ring can be assigned a ring ID. The communication protocol between the adjacent nodes can be modified to tag the signaling information with the appropriate ring ID.Type: ApplicationFiled: July 8, 2004Publication date: February 24, 2005Inventors: Anthony Kam, Raymond Xie, Tao Yang, Naimish Patel

Publication number: 20050041575Abstract: Each span of a communication network, such as a BLSR ring, is assigned a unique span ID. When a node of the network detects a failure in a span (including a straddling span) of the network, the node exchanges commands, according to an automatic protection switching (APS) protocol, that request other nodes of the network to switch network traffic from a working span (including a straddling span) to a protect span. The commands specify the working span by its span ID, without necessarily specifying a source node ID or a destination node ID for the commands. The span ID occupies fewer bits in the commands than a combination of the source node ID and the destination node ID. Consequently, the messages can accommodate span IDs larger than four bits, and networks can have more than 16 nodes. Alternatively, the commands specify a destination node ID without a span ID or a source node ID, or the commands specify a source node ID without a span ID or a destination node ID.Type: ApplicationFiled: July 7, 2004Publication date: February 24, 2005Inventors: Anthony Kam, Raymond Xie, Tao Yang, Naimish Patel

Patent number: 6839871Abstract: Indicia are provided to a client of Out-of-Frame errors and message bit parity errors that occur during the transmission of a message through a network, wherein the message includes the client data multiplexed with other data and formatted into a message that includes a plurality of transport overhead bytes. The transport overhead bytes of the multiplexed can include both defined bytes and undefined bytes. Predetermined bytes in the transport overhead may be used to store indicia of errors that are detected during the message transmission. These predetermined bytes are read by the client at the egress of the network. The transport overhead may contain both a section overhead portion and a line overhead portion and the predetermined bytes may be encoded in either a subset of the section or line overhead bytes. In addition, the indicia of errors may be encoded in an undefined portion of the section or line overhead.Type: GrantFiled: February 8, 2001Date of Patent: January 4, 2005Assignee: Sycamore Networks, Inc.Inventors: Naimish Patel, Richard A.

Patent number: 6754208Abstract: A method and apparatus are disclosed for spreading the component signals of a groomed input circuit through a three-stage CLOS switch network. The spreading algorithm includes sequentially evaluating each midstage switching module as to the availability of a connection between an assigned source switching module and an assigned destination switching module having sufficient spare bandwidth to accommodate one or more of the component signals. A load sharing algorithm can be used to spread the component signals among the midstage switching stages. In this way the available bandwidth of each of the midstage switching modules is evaluated for each of the component signals and each component signal is routed through the midstage switching module having the largest available bandwidth.Type: GrantFiled: August 1, 2001Date of Patent: June 22, 2004Assignee: Sycamore Networks, Inc.Inventors: Anthony Chi-Kong Kam, Naimish Patel

Patent number: 6681248Abstract: In a network having a trace capability, a method to track the connectivity of the network uses the trace messages. A network manager creates a list of ports in the network and uses that list to track the connectivity. For each port, the manager first checks whether there is a current connection and if it finds one, records the connection. For the unconnected ports, the manager enables the transmission of a trace message that identifies the transmitting port. When a trace detected message is received from a port, the network manager updates the list of ports with the connection just reported and disables the trace message that was detected. A port sending a trace message that is not detected is marked as not connected in the list. The method is useful in high bandwidth circuit-based networks, such as optical networks, composed of links of many types and utilizing differing protocols.Type: GrantFiled: April 12, 2000Date of Patent: January 20, 2004Assignee: Sycamore Networks, Inc.Inventors: William Sears, Joseph Zahavi, Naimish Patel

Patent number: 6504631Abstract: A network including a control channel source node and a plurality of control channel destination nodes is interconnected by communications media in the form of a ring. The control and control channel destination nodes transfer information over a plurality of channels using wavelength-division multiplex techniques. The control channel source node transmits control information to all of the control channel destination nodes over a unitary control channel, and each of the control channel destination nodes drains off a portion of the energy of the signal comprising the control channel to facilitate decoding and processing of the control information contained therein. Each of the aspects, the control channel destination nodes can also generate status information for transfer to the control channel source node over the control channel. The control channel source node drains off the energy of the signal comprising the control channel to facilitate decoding and processing of the status information contained therein.Type: GrantFiled: February 17, 1999Date of Patent: January 7, 2003Assignee: Sycamore Networks, Inc.Inventors: Richard A.
