Efficient codeword synchronization methods and systems for fiber channel protocol are disclosed. The method includes identifying a codeword boundary by detecting 100-bit known patterns in a bit codeword in a transmission.

The Distributed Software Defined Network (dSDN) disclosed herein is an end-to-end architecture that enables secure and flexible programmability across a network with full lifecycle management of services and infrastructure applications (fxDeviceApp). The dSDN also harmonizes application deployment across the network independent of the hardware vendor. As a result, the dSDN simplifies the network deployment lifecycle from concept to design to implementation to decommissioning.

The disclosure relates to a method, executed in a Network Function Virtualization Infrastructure (NFVI) software modification manager, for coordination of NFVI software modifications of a NFVI providing at least one Virtual Resource (VR) hosting at least one Virtual Network Function (VNF), comprising receiving an NFVI software modifications request; sending a notification that a software modification procedure of the at least one VR is about to start to a VNF level manager, the VNF level manager managing a VNF hosted on the at least one VR provided by the NFVI; applying software modifications to at least one resource of the at least one VR; and notifying the VNF level manager about completion of the software modifications.

A method for routing data packets to a distribution server, comprising generating server load data at the server using a processor. Compiling the server load data into a data update using the processor. Transmitting the data update from the server to one or more routers using a network data transmission system. Modifying a routing algorithm at the one or more routers to utilize the data update using an associated router processor.

Systems and methods provide for synergistic domain name system DNS security updates for an enterprise network operating under a Software Defined Wide Area Network (SD-WAN). A system may be configured to collect positive and/or negative unified threat defense (UTD) results, deploy a rules-based model that, when a threat or clearance is detected across several SD-WAN edge network devices, triggers an update to a local security blacklist/whitelist, wherein the update comprises a signature, and push the update to other devices that have not yet seen the threat or clearance.

Approaches for updating a firmware file in a network having multiple transceiver nodes and being capable of receiving and transmitting the firmware file include dividing the firmware file into multiple of chunks, each chunk being able to be included in a single data packet transmitted between two of the transceiver nodes; transmitting each of the chunks from the first one of the transceiver nodes to the second one of the transceiver nodes; transmitting a request message from the first one of the transceiver nodes to the second one of the transceiver nodes, the request message including information associated with the chunks that have been transmitted in step (b); and transmitting a responding message from the second one of the transceiver nodes to the first one of the transceiver nodes, the responding message including information associated with one or more chunks that are included in the request message but not received by the second one of the transceiver nodes.

Systems herein allow an administrator to efficiently set up user devices for use in a classroom environment. A management server can display a graphical user interface that includes selection options for defining and using carts of user devices. The carts can be selected and assigned to classes. The GUI also allows the administrator to specify which applications a class will use. Based on these selections, the management server can then manage which user devices install which applications, and allocate licenses accordingly.

An approach enables networking functionality to be configured at network switches for containers hosted by computing devices. A container supervisor on the network switch is configured to obtain, via a container network manager, container attribute data for containers hosted by the computing devices. The container network manager is configured to interact with and manage container orchestration engines on behalf of the containers. This allows the network switch to be container orchestration agnostic. The network switch enables networking functionality for the containers by updating container configuration data on the networking switch based upon the container attribute data obtained from the container network manager. This may include, for example, updating hardware tables on the network switch with the container attribute data to allow the network switch, and applications executing on the network switch, to perform networking functionality with respect to the containers.

In some implementations, a method is provided. The method includes determining that a network device will perform a reboot. The method also includes saving state information. The state information comprises data used by the network device to process address resolution protocol (ARP) messages. The method further includes initiating the reboot of the network device. The method further includes initiating a first ARP service. The first ARP service is configured to process ARP messages during the reboot of the network device.
