Patent number: 10462543Abstract: Methods and systems for optical data unit (ODU) path protection in a disaggregated optical transport network (OTN) switching system that include using plug-in universal (PIU) modules each having multiple ports for OTN to Ethernet transceiving and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules may enable various OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches. An egress PIU module may receive Ethernet packets via the Ethernet fabric from a working ODU path. In response to determining that a protection switch using a protection ODU path may be performed on the working ODU path, the egress PIU module may receive the Ethernet packets via the Ethernet fabric from the protection ODU path.Type: GrantFiled: January 30, 2017Date of Patent: October 29, 2019Assignee: FUJITSU LIMITEDInventors: Biaodong Cai, Richard Dunsmore, Rod Naphan, Sam Lisle, Deepak Patel, Iqbal Syed

Patent number: 10368150Abstract: Methods and systems of a leased line appliance (LLA) network switching system that includes using LLAs for leased line circuits (LLCs) to Internet Protocol (IP) transceiving, IP to LLCs transceiving, and an IP switch fabric having multiple parallel paths as a switching/routing network are disclosed. Each of the LLAs at the edge of the IP switch fabric may perform LLC to IP packet assembly procedures, may perform IP packet to LLC re-assembly procedures, and may utilize the protocol fields of the IP packet header of the IP packet for IP packet transport, which may enable the transport of very high speed leased line services to be carried over an IP/MPLS network using the IP switch fabric.Type: GrantFiled: September 7, 2018Date of Patent: July 30, 2019Assignee: Fujitsu LimitedInventors: Biaodong Cai, Rod Naphan, Richard Dunsmore

Patent number: 10219050Abstract: Methods and systems of a disaggregated optical transport network (OTN) switching system that include using plug-in universal (PIU) modules for OTN to Ethernet transceiving and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules may enable various OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches. A virtual line card may include a logical aggregation of a kth Ethernet switch sub-port of each of the corresponding Ethernet switch ports of each of the Ethernet switches. A virtual switch fabric may include multiple virtual line cards for the OTN switching system. Each of the virtual line cards may be associated with a virtual address that may correspond to a respective PIU module. The virtual address may include a media access control address associated with the respective PIU module.Type: GrantFiled: January 30, 2017Date of Patent: February 26, 2019Assignee: FUJITSU LIMITEDInventors: Biaodong Cai, Richard Dunsmore, Rod Naphan, Sam Lisle, Deepak Patel, Iqbal Syed, Brent Mayberry

Patent number: 10178453Abstract: Methods and systems for Ethernet fabric protection in a disaggregated OTN switching system that include PIU modules each having multiple ports for OTN to Ethernet transceiving and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules may enable various OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches. A first PIU module may detect a fault condition on an Ethernet fabric plane of the Ethernet fabric. In response to the detection, the OTN switching system may transmit the fault condition to other PIU modules to redirect optical data unit traffic away from the fault on the Ethernet fabric plane.Type: GrantFiled: January 30, 2017Date of Patent: January 8, 2019Assignee: FUJITSU LIMITEDInventors: Biaodong Cai, Richard Dunsmore, Rod Naphan, Sam Lisle, Deepak Patel, Iqbal Syed

Publication number: 20180197156Abstract: Methods and systems for software defined networking data flows includes receiving a request for content from a source, determining the amount of defined network resources required to support the request, comparing the required amount of defined network resources with an amount of network resources provisioned for the source, determining that the required amount of defined network resources exceeds the amount of network resources provisioned for the source, sending a flow request to a software defined networking controller for the request for content from the source, receiving compensation using a payment recording system in response to the flow request, and enabling a data flow associated with the request for content based on receiving compensation. The compensation may be received without a prior relationship with the source of the request for content being established.Type: ApplicationFiled: January 12, 2017Publication date: July 12, 2018Inventors: William Eugene Beesley, Rod Naphan

An OTN over Ethernet module in each of the PIU modules may enable various OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches. An ith port of the multiple ports of each PIU module may be connected to the ith Ethernet switch of each of the Ethernet switches. A PIU module may be associated with a respective sequential order of the Ethernet switches. The PIU module may transmit an Ethernet packet from an ith port of the PIU module corresponding to the ith Ethernet switch, where the ith port is selected based on the respective sequential order of the Ethernet switches.Type: GrantFiled: January 30, 2017Date of Patent: April 10, 2018Assignee: Fujitsu LimitedInventors: Biaodong Cai, Richard Dunsmore, Rod Naphan, Sam Lisle, Deepak Patel, Iqbal Syed
