The disclosure provides a new content server framework in which functionalities of a content server are implemented as lightweight microservices. At startup of the content server framework, a content server container and a set of microservices are launched. The content server container only has a content server application programming interface (API) which has a controller that can instantiate controller applications, each having a master module and worker(s). When a request is received, the content server API routes it to an appropriate microservice which stores the request in a repository. The master module retrieves the request from the repository and places it in a queue. The worker picks up the request from the queue and processes it. The controller keeps track of details of each controller application container that it instantiated (e.g., load and status) and automatically scale up or down the number of instances.

A system and method for observing and controlling a programmable network via higher layer attributes is disclosed. According to one embodiment, the system includes one or more collectors and a remote network manager. The one or more collectors are configured to receive network traffic data from a plurality of network elements in the network. The remote network manager is configured to connect to the one or more collectors over the Internet via a network interface. The one or more collectors extract metadata from the network traffic data and send the metadata to the network manager.

A network configuration diagram generate method executed by a computer, the method includes identifying, in a predetermined system in which a plurality of virtual machines are used, a location where each of the plurality of virtual machines is located and a communication destination with which each of the plurality of virtual machines communicates; determining, for each change in a configuration of the predetermined system, a relationship of a communication distance between the plurality of virtual machines by using the location and the communication destination, the configuration indicating a relationship of the plurality of virtual machines; extracting a difference between the relationship of the communication distance before the configuration change and the relationship of the communication distance after the configuration change; and generating a network configuration diagram in which the extracted difference is indicated.

A network device (ND) includes packet processing circuitry and performance optimization circuitry. The packet processing circuitry is connected to a network and is configured to process communication packets for communicating over the network. The packet processing circuitry includes a plurality of configuration registers for setting one or more operation parameters of the ND. The performance optimization circuitry is configured to improve a performance measure of the ND by iteratively calculating the performance measure and adjusting values of one or more of the configuration registers based on the performance measure.

Broadly speaking, embodiments of the present technique provide methods, apparatuses and systems for operating a configuration server in communication with a client electronic device, comprising: receiving a handshake initiation message from the client electronic device specifying a registration at a specified server; receiving, from the client electronic device, a first enumeration of client features supported; responsive to detecting no stored client provisioning configuration for the client electronic device, retrieving, from the specified server, a second enumeration of server features supported; performing a comparison between the first and the second enumeration to detect a match between the client features supported and the server features supported; responsive to detecting a match, creating a client provisioning configuration; storing the client provisioning configuration in a configuration store; and sending a provisioning message comprising the client provisioning configuration to the client electronic device.

A method of network reachability impact analysis includes receiving a plurality of network configuration snapshots for a network. The method also include selecting a first network configuration snapshot of the network and a second network configuration snapshot of the network. The method further includes generating a first reachability graph representing packet reachability of the network for the first network configuration snapshot. The method also includes generating a second reachability graph representing packet reachability of the network for the second network configuration snapshot. The method also includes computing a reachability differentiation graph identifying a net change to reachability from the first reachability graph to the second reachability graph. The method further includes generating a reachability differentiation report including a human-interpretable output of the net change to reachability.

The invention relates to a method for operating a network, wherein at least two network devices are connected to one another in the network via a data line and exchange data via this data line, wherein each network device is fixedly assigned an independent MAC address, wherein a network management station also controls the configuration and/or the operation of the network, characterised in that a query is sent from the network management station by multicast by means of the SNMP protocol to the network devices so as to query the configuration parameters of the network devices and/or configure the queried network device by SNMP.
