An apparatus such as a network switch includes a power supply device configured to control power supplied through ports such as Ethernet ports to the network devices such as wireless access portions that are part of a local network. The apparatus further includes a second power supply device with one or more switched outlets for providing direct power other devices of the local network. A controller in the apparatus may be programmed to control the power supply devices to execute to a diagnostic procedure or a reset procedure that cycles power, off and then on, to devices of the local network.

A network switch for implementing a Software Defined Network can include one or more memory resources storing a flow table and including a buffer. The network switch can receive and analyze data packets to generate a lookup key for each respective data packet. Using the lookup key, the network switch can perform a lookup in the flow table to determine a rule number for the respective data packet. Based on the rule number, the network switch can generate an event record for the respective data packet, and store the event record in a block of the buffer. When the block is full, the network switch can stream a set of event records from the buffer to a processing resource to enable the processing resource to update counter tables, external to the network switch, to implement the Software Defined Network.

Implementing a software defined network based on event records

An electronic device has a plurality of environments including respective communication stacks. The environments correspond to respective different user personas. Data associated with the different user personas are communicated in corresponding separate transport flows over the network.

Communicating data associated with different personas of a user

A protocol such as OpenFlow providing communication between an SDN framework controller on one network and a data plane device for another network can be used to modify or process network packets so that an external application or server can communicate with the controller and obtain information needed to uniquely associate the packets with particular end-stations even after those packets have traversed a NAT router.

Identifying end-stations on private networks

According to an example, a receiver having a physical (PHY) layer may receive a portion of a frame from a transmitter, in which the portion of the frame comprises information available at the PHY layer. A signature of the transmitter may be determined based upon the information available at the PHY layer and a hardware component in the PHY layer may determine whether to continue to receive the frame based upon the determined signature of the transmitter.

Making a frame receive decision in a receiver PHY layer

A cloud-based connectivity system is disclosed. The system includes a plurality of wireless devices and a computing device connected to at least one of the wireless devices. The computing device includes a control unit to receive context information from each of the plurality of wireless devices, to determine future consumption patterns for each of the plurality of wireless devices by using the received context information, to create a connectivity representation for the plurality of wireless devices, and to determine an optimal network topology for the plurality of wireless devices.

Cloud-based connectivity

Embodiments of the present disclosure may include methods, systems, and computer readable media with executable instructions. An example method for network virtualization can include providing, by a datacenter () having physical and/or virtual resources, a number of virtual tenant datacenters (tDatacenters), each tDatacenter being isolated from other tDatacenters. A tenant virtual local area network (T-VLAN) () is associated to each of the number of tDatacenters, and a value of an end-to-end invariant network virtual local area network (VLAN) identification (VID) label (T-VID) is associated to a particular T-VLAN (). A network packet associated with the particular T-VLAN () is modified at an edge network boundary () to include the T-VID. The T-VID is configured to have more than 4096 possible values.

Network virtualization

A network switch for reducing TCP timeouts due to incast collapse is disclosed. The network switch has a plurality of buffers for storing network packets for at least one sender server. An incast buffer management component in the network switch allocates a buffer in the plurality of buffers to store an incast notification packet, the incast notification packet indicating one or more network packets that have been dropped by the network switch. The network switch also includes an incast notification component for forwarding the incast notification packet to a destination server with an incast notification packet specific header.

Agreement information based on agreements between an intermediary service provider and a plurality of provider entities that operate respective multiple equipment is stored by an intermediary system. The agreement information includes information to enable access of each of the multiple equipment by a client device. Client information associated with the client device is also stored by the intermediary system. The agreement information is useable to provide access by the client device of selected ones of the equipment.

Providing agreement information to allow access by a client device of selected equipment from among multiple equipment

Data for a first persona of a user of an electronic device is communicated in a first access network, according to a first agreement between the user and a first service provider of the first access network. Data for a second, different persona of the user is communicated in the first access network, according to a second, different agreement.

Controlling communication of data for different user personas

A probe request from a wireless station can cause the access point to contact a roaming enablement service and alter the services accessible through the access point. The roaming enablement service can identify preferred services of the wireless station and mediate automated negotiations between the access point and a service provider to determine whether the access point may provide a service from the service provider. Upon successful negotiations, the brokerage service can enable the access point to provide access to the preferred services.

Initializing network advertisements from probe requests

Each of a plurality of data packets that is received on a network switch can be associated with a corresponding event record that identifies one or more flow table rules for that data packet. A plurality of event records, which individually can correspond to one or more of the data packets, is transmitted to a programmable resource for use in controlling a Software Defined Network.

Implementing a software defined network using event records that are transmitted from a network switch

A method for selecting a command file is described. One or more command files coupled with a first device are accessed. Each command file of the one or more command files comprises one or more command file attributes. One or more device attributes associated with a second device are accessed. The one or more command file attributes and the one or more device attributes are compared to determine a correlation between the one or more command files and the second device. Based on the comparing, generating a ranked portion of the one or more command files according to the correlation.

Selecting a command file

One embodiment disclosed relates to a method for a switch to respond to a new client. A new client is detected at a port of the switch. The switch temporarily assigns the port to be an untagged member of a virtual local area network (VLAN) which is configured for unauthorized clients. Initialization services are provided to the new client via the unauthorized-client VLAN. The new client may be authenticated by way of an authentication session using the unauthorized-client VLAN. If the new client is authenticated, then the untagged membership of the port in the unauthorized-client VLAN is dropped, and the port is assigned to be an untagged member of a specified VLAN.

Method and apparatus for access security services

A system and method for implementing a VM to identify a data packet for transmission, the data packet including a QoS the data packet is to receive as compared to another QoS that another data packet is to receive. The system and method further includes a SNIC to pull the data packet from the VM based upon the QoS the data packet is to receive. The system and method may also include a link scheduler module to transmit the data packet based upon the QoS the data packet is to receive. The system and method may also include a receiver to receive a management instruction from a network management device, the management instruction to dictate the QoS the data packet is to receive based upon a SLA.
