Patent number: 9942365Abstract: Separating and isolating multiple network stacks in a network element may enable a network element to simultaneously operate within multiple forwarding planes respectively corresponding to the multiple network stacks. In addition to the network stack, other protocols and routing tools may also be instantiated for each desired forwarding plane. The different instantiations of the network stacks may be executed in parallel in respective memory spaces that are distinct and separate. In this manner, each forwarding plane may operate independently on the network element from other forwarding planes.Type: GrantFiled: March 21, 2014Date of Patent: April 10, 2018Assignee: Fujitsu LimitedInventors: Albert V. Smith, Nasir Iqbal Amanullah, Bradford J. Dobson, Tintooda Nakakes, Steven M. Simmons

Patent number: 9929966Abstract: In a system having multiple internal Internet protocol (IP) stacks, such as a network element, a value of a time-to-live (TTL) parameter may not be changed by an ingress IP stack. An indication of internal forwarding within the system may be used. An egress IP stack may decrement the value of the TTL parameter. A public network address for the system may be used for response packets to diagnostic packets received by the system.Type: GrantFiled: January 6, 2015Date of Patent: March 27, 2018Assignee: Fujitsu LimitedInventors: Tintooda Nakakes, Albert V. Smith, Nasir Iqbal Amanullah, Joseph Nguyen, Xinxin Sun

Patent number: 9473832Abstract: Systems and methods for tunneling GCC0 bytes over an OTN transport network are disclosed. The method includes receiving, at a first network element, a first data frame comprising a set of management bytes and a set of data bytes, determining whether the set of management bytes should be tunneled, and, in response to determining that the management bytes should be tunneled, sending, to a second network element, a second data frame comprising the set of management bytes and the set of data bytes.Type: GrantFiled: November 13, 2014Date of Patent: October 18, 2016Assignee: Fujitsu LimitedInventors: Maitreya Mukhopadhyay, Albert V. Smith, Jr., Catherine Yuan

Patent number: 8982900Abstract: Routing around intra-network element (intra-NE) disconnectivity is described. The routing is performed on one or more network element (NEs) of a channelized network. The routing involves performing a shortest-path-search (SPS) to determine a shortest non-disconnected path from a single path-ingress edge to a single path-egress edge. The SPS includes classifying a set of endpoints of each NE in the channelized network as an equivalence class of endpoints, classifying a set of paths-so-far between each NE in the channelized network as an equivalence class of paths-so-far, grouping each equivalence class of paths-so-far by the equivalence class of endpoints that includes a terminal endpoint of the path-so-far that is furthest from the single path-ingress edge, and exploring separately each equivalence class of edges that are incident to each NE when determining the shortest non-disconnected path from the single path-ingress edge to the single path-egress edge.Type: GrantFiled: April 25, 2012Date of Patent: March 17, 2015Assignee: Fujitsu LimitedInventors: Daniel Louis Miller, Ladan Pickering, Sanjay Gera, Edward A. Harbin, Albert V. Smith, Jr.

Patent number: 8908522Abstract: A method may include monitoring data packets at a data transmission channel. The data packets may be identified as nonconforming or as conforming data packets. Data packets may be identified as nonconforming if a data transmission rate would exceed a data rate threshold if the data packets were allowed to continue along the data transmission channel. Data packets may be identified as conforming if a data transmission rate would not exceed the data rate threshold if the data packets were allowed to continue along the data transmission channel. The nonconforming data packets may be retained as retained data packets. The retained data packets may again be identified as nonconforming data packets or conforming data packets after a retaining time. Data packets identified as conforming data packets may be released.Type: GrantFiled: April 30, 2012Date of Patent: December 9, 2014Assignee: Fujitsu LimitedInventors: Albert V. Smith, Jr., Asmita Borlepwar

Patent number: 8295204Abstract: According to a particular embodiment, a method for automatically assigning dynamic IP addresses without user interaction includes maintaining at least one pool of unused IP addresses. An advertisement message is transmitted from a first network element to at least one additional network element in a transport ring. The advertisement message identifies the first network element as providing IP address assignment services. The IP address request message from a second network element in the transport ring is received at the first network element. In response to the IP address request message, an IP address is dynamically assigned from the at least one pool of unused IP addresses. The dynamically assigned IP address is transmitted from the first network element to the second network element.Type: GrantFiled: February 22, 2008Date of Patent: October 23, 2012Assignee: Fujitsu LimitedInventors: Richard J. Dunsmore, Albert V. Smith, Jr., Man Wing Fong, Joseph K. Nguyen, Su Wang
