A method of measuring, for communication paths between a networked computer and at least one other networked computer connected via a network performance, network information to detect network performance degradation and diagnose source(s) of the performance degradation. The diagnosis may be performed by a progressive elimination of possible sources. Network performance degradation may be attributed to problems at a local network or the Internet. The problem sources on the Internet may comprise, for example, an internet server provider (ISP) or a single remote server in communication with the networked computer. A network performance baseline established and maintained for each path may be employed in diagnosing the network performance degradation.

A network performance monitor for a computer. The performance monitor maintains a baseline for communication paths between a networked computer and other networked computers connected. The network performance baseline is established and maintained by measuring and updating network performance parameters of the communication paths. The network performance parameters are updated using values obtained during time intervals when the communication path consumed a bandwidth approximately equal to its estimated bandwidth. If congestion is detected on the network or the network is underutilized, values of the network performance parameters obtained during that interval are not used to update the network performance parameters. Some performance parameters in the baseline, such as minimum and maximum bandwidth values may be updated by computing a moving average of each parameter. Asymmetric weight values for updating the moving average may be selected based on a direction of change of a value of a network parameter.

Techniques for proxy based network access are discussed herein. In some examples, the techniques can be implemented in a network proxy device for Citizens Broadband Radio Service (CBRS). A base station or a domain proxy device may manage or otherwise use CBRS resources by exchanging signaling messages with a Spectrum Access System (SAS). The base station or domain proxy device may transmit signaling messages in a first private network to a network device bridging the first private network and a second private network with limited access to a public network. The network device send proxy message(s) in response to the signaling messages to the SAS and can establish an encrypted session layer or application layer tunnel between the base station and/or domain proxy device. The proxy based network access preserves secure networks while still allowing limited messaging with other public or private networks.

This document describes, among other things, systems and methods for more efficiently resuming a client-to-origin TLS session through a proxy layer that fronts the origin in order to provide network security services. At the time of an initial TLS handshake with an unknown client, for example, the proxy can perform a set of security checks. If the client passes the checks, the proxy can transmit a ‘proxy token’ upstream to the origin. The origin can incorporate this token into session state data which is passed back to and stored on the client, e.g., using a TLS session ticket extension field, pre-shared key extension field, or other field. On TLS session resumption, when the client sends the session state data, the proxy can recover its proxy token from the session state data, and upon successful validation, bypass security checks that it would otherwise perform against the client, thereby more efficiently handling known clients.

A system includes a processor and a computer-readable medium storing instructions for execution. The instructions include generating a cryptographic pair of user public and private keys for a user. The instructions include registering an identity of the user with an identity provider, transmitting the user public key, and receiving a user certificate from the identity provider. The instructions include signing a trust certificate for a web server, including an address and a public key of the web server, with the user private key. The instructions include, in response to an access request from the user specifying a second web server: obtaining a second trust certificate from the second web server; and establishing a connection with the second web server in response to successful verification of a signature of the second trust certificate using a public key corresponding to a trusted contact of the user.

The invention relates to sealable short-pathlength liquid transmission cells for Fourier-transform infrared spectroscopy applications. In exemplary embodiments, a liquid transmission cell with transmissions sections uses horizontal tubing for inserting and removing fluids from the cell. Angling the tubing relative to a top face of the cell allows small amounts of entrapped air to rise out of the optical path without blocking spectroscopy measurements. The tubing is silver-soldered to the body of the transmission cell to make a leak-free connection.
