Publication number: 20210243157Abstract: A network device identifies an Internet Protocol Security (IPsec) tunnel that connects the network device to a remote device and determines that dead peer detection (DPD) is enabled at the network device. The network device receives a first DPD request message from the remote device via the IPsec tunnel, and sends a first DPD response message to the remote device via the IPsec tunnel. The network device determines that a workload of the network device satisfies a threshold amount, and sends one or more encapsulating security payload (ESP) packets that include traffic flow confidentiality (TFC) payload data to the remote device via the IPsec tunnel. The network device determines that the workload of the network device does not satisfy the threshold amount. The network device receives a second DPD request message from the remote device and sends a second DPD response message to the remote device via the IPsec tunnel.Type: ApplicationFiled: April 19, 2021Publication date: August 5, 2021Inventors: Naresh Chand, Ranjan Sinha

Patent number: 8406427Abstract: A communication network includes a local area network (LAN) and a wireless access point coupled to the LAN. In one embodiment, each access point includes a medium access control (MAC) stage, and a radio frequency (RF) transmitter/receiver for communicating unsecure message data via RF links with users of associated wireless devices. An optical transmitter/receiver in the access point enables the users to communicate secure message data over the LAN via free space optical (FSO) links with the users. The MAC stage operates (i) to direct unsecure data from the LAN to the wireless device users and to direct unsecure data from the users to the LAN, via the RF transmitter/receiver; and (ii) to direct secure data from the LAN to the wireless device users and to direct secure data from the users to the LAN, via the optical transmitter/receiver. An integrated VoIP/FSO portable handset is also disclosed.Type: GrantFiled: October 13, 2009Date of Patent: March 26, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Naresh Chand, Bruce M.

Patent number: 8032032Abstract: A fiber optic link for platforms with data sources including, e.g., sensors, cameras, radars and antennas. An array of optical transmitter/receiver pairs is coupled to an integrating network of the platform. Data modules are each coupled to certain ones of the data sources and include a receiver for detecting control data, and a modulator for modulating a light signal according to signals from the module's data sources. At least one optical fiber is coupled between a given transmitter/receiver pair of the array, and a corresponding data module. A laser source associated with each transmitter supplies a light signal with the control data to a corresponding data module downstream over an optical fiber. The light signal is modulated by the signals from the module's data sources, and the modulated light signal is returned to an array receiver upstream over an optical fiber.Type: GrantFiled: November 14, 2008Date of Patent: October 4, 2011Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Naresh Chand, Kevin M.

Patent number: 7373089Abstract: Methods and apparatus for providing improving optical signal transmission results over standard mode fiber using a combination of negative chirp, low extinction ratio, and self-phase modulation transmission techniques in combination are described. The use of pre-transmission signal distortion in combinations with one or more of the other transmission techniques is also described. Pre-transmission signal distortion may be introduced by controlling a modulator with a large symmetric AC signal which causes the modulator to operation in a non-linear region or, alternatively, by using a relatively small non-symmetric AC signal to drive the modulator. Use of the small non-symmetric signal has the advantage of reduced power requirements. The pre-transmission distortion acts to counter some of the distortion introduced by the transmission of the signal over an optic fiber.Type: GrantFiled: August 9, 2002Date of Patent: May 13, 2008Assignee: LSI CorporationInventors: Jianjun Yu, Keisuke Kojima, Naresh Chand
