Abstract: Systems and methods are described to provide fault tolerant folded Clos networks. A folded Clos network is disclosed including a set of tier 1 routers interconnected with a set of tier 2 routers. Tier 1 routers are configured to view a set of tier 2 routers as a single aggregate router. Accordingly, tier 1 routers are unaware of faults between tier 2 routers and additional tier 1 routers. A throwback router is connected to each tier 2 router to facilitate handling of data under such fault conditions. When a tier 2 router receives undeliverable data, the data is passed to a throwback router, which retransmits the data to an additional tier 2 router. Data that is retransmitted multiple times can be disregarded by the throwback router.

Abstract: Methods and apparatus for remapping IP addresses of a network to endpoints within a different network. A provider network may allocate IP addresses and resources to a customer. The provider network may allow the customer to remap an IP address to an endpoint on the customer's network. When a packet is received from a client addressed to the IP address, the provider network may determine that the IP address has been remapped to the endpoint. The provider network may translate the source and destination addresses of the packet and encode the packet for transmission over a private communications channel. The encoded packet may be sent to the endpoint via the private communications channel over an intermediate network. Response traffic may be routed to the client through the provider network, or may be directly routed to the client by the customer network.

Abstract: Private network address obfuscation and verification methods and apparatus that may obfuscate private network source addresses embedded in packet header addresses when sending packets from private networks onto or over external, public networks, and that verify incoming packets to the private networks using the obfuscated private network addresses embedded in the incoming packet header destination addresses. Obfuscating the private network addresses embedded in outgoing packets and verifying incoming packets according to the obfuscated content embedded in the destination addresses may help keep the private network addresses of endpoints on the private network hidden in the packet header content on public networks and difficult to detect by entities on the public networks, which may, for example, make malicious activities such as denial of service (DoS) attacks on the private network impractical.

Abstract: Techniques are disclosed for dividing a TCP handshake into multiple parts, in a system comprising an edge device, an intermediary computing node, and a destination computing node. A client sends a TCP SYN packet to the edge device, to establish a TCP connection with the destination computing node. The edge device performs the handshake, and then forwards an ACK packet to the intermediary computing node. The intermediary computing node uses that ACK packet to generate a second SYN packet, and uses that SYN packet to perform a TCP handshake with the destination computing node. Then, TCP sequence numbers are converted between what is expected by the client and destination in packets sent between the two.

Abstract: A drilling system comprises a drilling parameter sensor in communication with a sensor application 22 that generates processed data from raw data that is received from the drilling parameter sensor. A process application 24 is in communication with the sensor application 22 and generates an instruction based on the processed data. A priority controller is in communication with the process application 24 and evaluates the instruction for release to an equipment controller 14 that then issues the instruction to one or more drilling components.

The extremity support is mounted on a mobile support which allows the device to be easily used when the subject is laying on a bed.

Abstract: A polymer containing an optionally substituted repeat unit of formula (I) wherein each R is the same or different and represents H or an electron withdrawing group, and each R1 is the same or different and represents a substituent.

Abstract: Methods and apparatus for transparent multipath utilization through encapsulation are disclosed. Respective encapsulation packets are generated for at least two different baseline packets transmitted between a source and destination linked by multiple network paths. Each encapsulation packet comprises contents of a corresponding baseline packet, and one or more data values selected in accordance with a path balancing policy. The data values added to one encapsulation packet may differ from those added to another. Different network paths to the destination may be selected for different encapsulation packets of a given transmission based at least in part on the added data values.

Abstract: Described herein are organoids comprising admixtures of selected bioactive primary renal cells and a bioactive cell population, e.g., an endothelial cell populations, e.g. HUVEC cells, and methods of treating a subject in need thereof with such organoids. Further, the isolated renal cells, which may include tubular and erythropoietin {EPO}-producing kidney cell populations, and/or the endothelial cell populations may be of autologous, syngeneic, allogeneic or xenogeneic origin, or any combination thereof. Further provided are methods of treating a subject in need with the organoids.

Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.

Abstract: In the event of loss of connection (4) between an access point (3) and a data network (5), the access point (3) transmits instructions to a data processing device (1) connected to the access point (3) to cause the data processing device (1) to re-establish connection to the data network (5) by another means. These instructions cause the data processing device to scan for beacon signals from further wireless access points, and establish connection (7, 8) to the data network (5) through a wireless access point (6) identified in the scanning process.
