The present invention relates to fast start-up of powered devices (22) connected to a power sourcing equipment (10') in a Power over Ethernet system (100). A stored voltage-current profile of an initial powering phase of a powered device (22) is provided. A voltage level provided to the powered device (22) in a subsequent initial powering phase of the powered device (22) is adjusted as long as a value corresponding to a current voltage level of a voltage-current profile of the subsequent initial powering phase deviates less than a predetermined threshold level from its corresponding value of the stored voltage-current profile of the initial powering phase of the powered device (22) and until a predetermined voltage level is reached. This can allow detecting whether a previously connected powered device (22) was replaced by another powered device (22) and to immediately start-up an unchanged powered device (22) with previously used operation parameters.

A method for providing a deterministic behavior in a shared physical network is disclosed. The method may be performed in a device controlling a Virtual Local Area Network, VLAN, of the shared physical network. The method includes rate limiting amount of inbound traffic for each traffic flow in the VLAN and assigning a respective priority for each traffic flow in the VLAN.

The avionic system of an aircraft includes a set of avionic computers and a switch associated with each avionic computer. For each avionic computer of the set of avionic computers, the avionic system includes a communication link between the switch associated with this avionic computer and each of the switches associated with the other avionic computers. Each switch is configured such that it routes the data frames received on its input ports to its output ports in a manner predefined only on the basis of the input ports on which these data frames are received. The various switches are configured such that, when an avionic computer sends a data frame, this data frame is transmitted to all of the other avionic computers.

Examples are described herein that relate to a mesh in a switch fabric. The mesh can include one or more buses that permit operations (e.g., read, write, or responses) to continue in the same direction, drop off to a memory, drop off a bus to permit another operation to use the bus, or receive operations that are changing direction. A latency estimate can be determined at least for operations that drop off from a bus to permit another operation to use the bus or receive and channel operations that are changing direction. An operation with a highest latency estimate (e.g., time of traversing a mesh) can be permitted to use the bus, even causing another operation, that is not to change direction, to drop off the bus and re-enter later.

Disclosed is a self-contained mesh radio extension unit, comprising a receiving sleeve having an open volume and a first data connector for communicative coupling to a communication device or cellular phone inserted in the open volume. A low-gain internal antenna and a high-gain external antenna are coupled to a digital data link (DDL) with a first DDL operating frequency. The DDL provides bidirectional internet protocol (IP) connectivity between the first data connector and a peer-to-peer meshed communication network, controlling one or more of the antennae as transceivers at the first DDL operating frequency. An integrated power supply system powers the DDL and includes a rechargeable internal battery and an external power interface. A control system automatically routes IP packets received or transmitted by the DDL and includes a network address translation (NAT) router and an IP addressing service for assigning and tracking IP addresses across the peer-to-peer meshed communication network.

An Ethernet solid-state drive (eSSD) system includes a plurality of eSSDs, an Ethernet switch and a baseboard management controller. The Ethernet switch is coupled to each of the eSSDs, and the baseboard management controller is coupled to the each of the eSSDs and to the Ethernet switch. The baseboard management controller controls the Ethernet switch to provide to each eSSD a corresponding predetermined bandwidth that is based on bandwidth information for the eSSD that is stored in a policy table of the baseboard management controller. The at least one predetermined bandwidth may include a predetermined ingress bandwidth and a predetermined egress bandwidth for the corresponding eSSD. The at least one predetermined bandwidth may be based on a service level associated with the corresponding eSSD, and may be adaptively based on operating parameters of the corresponding eSSD.
