Systems, computer-readable media, and methods are disclosed for parallel data processing for service function chains with network functions spanning multiple servers. An example system includes a first server hosting a first network function of a service function chain, a second server hosting a second network function of the service function chain, a mirror function deployed in a first switch to replicate a plurality of packets received by the system and to send respective copies of the plurality of packets to the first network function and to at least one of the second network function and a third network function of the service function chain, and a merge function deployed in a second switch to merge respective outputs of the first network function and the at least one of the second network function and the third network function.

Some embodiments provide a novel method for deploying different virtual networks over several public cloud datacenters for different entities. For each entity, the method (1) identifies a set of public cloud datacenters of one or more public cloud providers to connect a set of machines of the entity, (2) deploys managed forwarding nodes (MFNs) for the entity in the identified set of public cloud datacenters, and then (3) configures the MFNs to implement a virtual network that connects the entity's set of machines across its identified set of public cloud datacenters. In some embodiments, the method identifies the set of public cloud datacenters for an entity by receiving input from the entity's network administrator. In some embodiments, this input specifies the public cloud providers to use and/or the public cloud regions in which the virtual network should be defined. Conjunctively, or alternatively, this input in some embodiments specifies actual public cloud datacenters to use.

A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user’s account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

A non-transitory computer-readable recording medium is provided in which a port switching program for causing a computer to execute a process including: transmitting, in response to a mirror switching instruction that specifies a migration source port and a migration destination port, a first mirror switching notification to a virtual switch that has the migration destination port to request a change of mirror setting in the migration destination port; canceling mirror setting for a transmission packet to the migration destination port in the migration source port; and canceling mirror setting for a received packet from the migration destination port in the migration source port in response to a second mirror switching notification from the virtual switch, the second mirror switching notification indicating the change of the mirror setting in the migration destination port is stored.

A switching device is enabled to automatically perform one or more actions based on one or more notifications received thereby. A notification may be received by a device communicatively coupled to the switching device, or alternatively, may be internally-generated. Upon receiving the notification, the switching device utilizes a notification-to-action mapping to determine which action(s) are to be performed based on the notification received. The action(s) include automatically switching the switching device to a device coupled to a port thereof and/or automatically launching an application executing on that device in order to view the notification and/or content associated with the notification. In other example, the action(s) may include sending the notification to another device, such as a user's mobile phone and/or causing an application executing on the mobile phone to be launched in order to view the notification and/or content associated with the notification.

Systems and methods of configuring, managing and ensuring security compliance of Virtual Network Slices that transit through physical networks, virtual networks (SDN), cloud networks, radio access networks, service provider networks, and enterprise networks are identified. The methods include user side security validation methods while attempting to use a network slice for a specific service, and security validation of physical or virtual networks and the associated transit network elements. The methods disclose enriching the Security Certificates with policy parameters and the associated procedures that transit elements are required to assure for security compliance. Additionally, methods for incorporating a mobile native security platform in Wireless Mobile Network (4G/5G) that supports generating X.509 Certificates enhanced with policy requirements, validating allowed/disallowed list of transit network vendor devices, virtual network appliances are identified.

Embodiments of the present invention disclose a method and apparatus for processing a cluster in a cluster system, and a cluster system, relate to the field of communications technologies, and are invented for effectively simplifying a cluster system. The method includes: sending, by switched fabric board of a member device, a request answer signal for requesting a main control board that receives the request answer signal to answer the request answer signal; and if the switched fabric board do not receive an answer signal of the request answer signal, sending, by the switched fabric board, an address of a main monitoring module to a main control board of a main device. The present invention may be applied to a clustering technology.
