Abstract: embodiments herein described an optical system for testing the bandwidth of a photodiode (pd) in a photonic integrated circuit (pic). in one embodiment, a first optical signal is provided to bias one or more pds in the pic which generate a dc bias (e.g., dc voltage) across the pd whose bandwidth is being tested. a second optical signal is directed to the pd being tested, thereby generating an ac signal. the second optical signal can be a tunable optical signal where its frequency/wavelength is varied to test the bandwidth of the pd. the ac signal generated by the pd being tested is passed through a heating element (e.g., a resistor) which generates heat. this heat is then measured by an interferometer. the output of the interferometer can be correlated to a bandwidth of the pd.

CPC Code(s): H04L47/193
Abstract: techniques for a tcp proxy to communicate over a leo satellite network on behalf of a client device by selecting a tcp congestion-control algorithm that is optimal for the leo satellite network based on the time of day and/or location of the tcp proxy. based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different tcp congestion-control algorithms may be more optimized to communicate data through the leo satellite network. however, client devices generally use a single tcp congestion-control algorithm to communicate over wan networks. accordingly, a tcp proxy may be inserted on, for example, a router to communicate with the client device using a tcp congestion-control algorithm that the client device is configured to use, but then communicate over the leo satellite network using a different tcp congestion-control algorithm that is optimal based on the time of day and/or other factors.

CPC Code(s): H04L49/104
Abstract: an endpoint group (epg) can be stretched between the sites so that endpoints at different sites can be assigned to the same stretched epg. because the sites can use different bridge domains when establishing the stretched epgs, the first time a site transmits a packet to an endpoint in a different site, the site learns or discovers a path to the destination endpoint. the site can use bgp to identify the site with the host and use a multicast tunnel to reach the site. a unicast tunnel can be used to transmit future packets to the destination endpoint. additionally, a stretched epg can be segmented to form a micro-stretched epg. filtering criteria can be used to identify a subset of the endpoints in the stretched epg that are then assigned to the micro-stretched epg, which can have different policies than the stretched epg.

IPC Code(s): H04L61/2503, H04L61/4511
CPC Code(s): H04L61/2503
Abstract: techniques for using network address translation (nat), mobile internet protocol (mip), and/or other techniques in conjunction with domain name system (dns) to anonymize server-side addresses in data communications. rather than having dns provide a client device with an ip address of an endpoint device, such as a server, the dns instead returns a virtual ip (vip) address that is mapped to the client device and the endpoint device. in this way, ip addresses of servers are obfuscated by a virtual network of vip addresses. the client device may then communicate data packets to the server using the vip address as the destination address, and a virtual network service that works in conjunction with dns can convert the vip address to the actual ip address of the server using nat and forward the data packet onto the server.

Abstract: a method of implementing controller-based distributed remote access may include connecting a plurality of edge devices to a controller via a network. the plurality of edge devices may perform hole punching to traverse a network address translation (nat) gateway to create a nat hole. the method may also include connecting a client device to the controller. the client device may be directly connected to one of the plurality of edge devices via the nat hole in the network. the method may further include directly connecting the client device to one of the plurality of edge devices by receiving a query from the client device and returning public ip/ports of a most relevant edge device to the client device, the most relevant edge device being based on attributes of the client device, attributes of the plurality of edge devices, or combinations thereof.
