Abstract:

An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. The medical article is disposed on and slideable along the dilator. A track extends in a proximal direction from the dilator. The needle hub slides along at least a portion of the track between a first position and a second position. The device further includes a locking mechanism operably disposed between the track and the needle hub so as to inhibit further axial movement of the needle in the proximal direction when the needle hub is in the second position.

International Classification:

H04L 12/24
H04L 12/28
H04L 29/06

Abstract:

A method for managing multiple software defined wide area network (SD-WAN) software versions includes providing a controller that defines an overall configuration for an SD-WAN and that creates configuration registries for individual SD-WAN appliances to implement their respective portions of the overall configuration. The controller generates, in an intermediate configuration language registry format, a first and second configuration registry for first and second SD-WAN appliance that respectively execute first and second versions of SD-WAN software. The controller respectively transmits the first and second configuration registries to the first and second SD-WAN appliances, which use the first and second configuration registries to configure themselves. The first and second SD-WAN appliances negotiate with each other for common SD-WAN features usable to implement configurations specified in the first and second configuration registries.

Abstract:

Techniques are described to automatically activate and deactivate standby backup paths in response to changing bandwidth requirements in an adaptive private network (APN). The APN includes one or more regular active wide area network (WAN) links in an active mode and an on-demand WAN link in a standby mode. The on-demand WAN link is activated to supplement the conduit bandwidth when an available bandwidth of the conduit falls below a pre-specified trigger bandwidth threshold and the conduit bandwidth usage exceeds a usage threshold of a bandwidth of the conduit that is being supplied by the active paths (BWc). The on-demand WAN link is deactivated to standby mode when an available bandwidth of the conduit is above the pre-specified trigger bandwidth threshold and the conduit bandwidth usage drops below the usage threshold of BWc techniques for adaptive and active bandwidth testing of WAN links in an APN are also described.

Abstract:

Systems and techniques are described for a path maximum transmission unit (MTU) discovery method that allows the sender of IP packets to discover the MTU of packets that it is sending over a conduit to a given destination. The MTU is the largest packet that can be sent through the network along a path without requiring fragmentation. The path MTU discovery method actively probes each sending path of each conduit with fragmentation enabled to determine a current MTU and accordingly increase or decrease the conduit MTU. The path MTU discovery process is resilient to errors and supports retransmission if packets are lost in the discovery process. The path MTU discovery process is dynamically adjusted at a periodic rate to adjust to varying network conditions.

Abstract:

System and techniques are described which apply a method for automatic database schema migration. An initial database is installed, according to rules that define tables of data, in an adaptive private network (APN) having a centralized management system including a network control node (NCN) coupled through the APN to a plurality of client nodes, wherein the NCN provides timing and control to the client nodes. An update to the initial database is received, wherein the initial database includes a first table of data stored in a first set of columns and the updated database includes a modified first table having a second set of columns that has a different number of columns as compared to the first table is automatically detected. One or more columns from the second set of columns that are different than the first set of columns are updated for data content.
