This disclosure describes a payload pipeline system that, as part of an inter-network facilitation system, can facilitate digital payload throughput between network components using a staggered payload relayer. For example, the disclosed systems utilize custom tooling to implement a staggered payload relayer as an intelligent conduit or pipeline that operates as a publisher-subscriber paradigm system (as opposed to a data stream system). In some cases, the disclosed systems can utilize synchronous or asynchronous communication to receive digital payloads for events from publisher network components and to make the digital payloads available within a payload queue maintained by the staggered payload relayer (for access by subscriber network components).

A module unit for connecting a data bus participant to a local bus. The module unit has a first input interface and a first output interface which can be connected to the local bus, a first data connection interface which can be connected to the data bus participant, and a first switch which is adapted so as to assume a first or a second switch state depending on a control input from the data bus participant, connect the first input interface to the first output interface in the first switch state, and connect the first data connection interface to the first output interface in the second switch state.

A virtual Intranet acceleration method includes, upon receiving a TCP request from a server at an initiating end to be sent to a server at a receiving end, customer premise equipment CPE at the initiating end transmitting information of the TCP request to CPE at the receiving end, the CPE at the receiving end configuring a connection link between the server at the initiating end and the server at the receiving end according to the information of the TCP request, and transmitting at least one of the TCP request or TCP response data through the connection link.

Concepts and technologies for point-to-point data synchronization are provided. A personal area network connection between a first user device and a second user device is established. State change information of first data stored on the first user device is received by the second user device, and second data stored on the second device is updated to reflect the state change to synchronize the first data and the second data. Alternatively, a synchronization message including the state change information of first data stored on a first user device is received by the second user device. The state change information is extracted from the synchronization message, and second data stored on a second user device is updated to reflect the state change to synchronize the first data and the second data.

A method of operating a data network may include establishing a data path through the data network between a routing gateway and service provider equipment providing a data service. Moreover, the data service may be provided for use at the routing gateway over the data path during a data session. A request may be received from the service provider equipment where the request defines a data flow characteristic for the data path between the routing gateway and the service provider equipment providing the data service. The data flow characteristic may then be transmitted to a network element along the data path between the routing gateway and the service provider equipment. A request from service provider equipment can include an allowed bandwidth or prioritization. Related methods, data networks, data service providers, routing gateways, and computer program products are also discussed.

Methods and apparatuses for PW redundancy have been provided. A network node across a first domain and a second domain is disclosed. In each domain, the network node and at least one second network node form a first redundancy group (RG) in the first domain and a second RG in the second domain. The network node comprises a first set of interfaces facing the first domain, a second set of interfaces facing the second domain, and a forwarder. In the first set, at least a first and a second interfaces are configured for connecting with PW segments within the first domain; in the second set, at least a first and a second interfaces are configured for connecting with PW segments within the second domain. A third interface in the first set and a third interface in the second set are configured for transferring traffic between the network node and the at least one second network node and between the first domain and the second domain. The forwarder is configured for forwarding traffic selectively between one interface of the first set and one interface of the second set.

A layer 2 tunneling protocol access concentrator (LAC) may receive an indication to set up a layer 2 tunneling protocol (L2TP) tunnel. The LAC may determine, based on the indication, a multicast address associated with initiating setup of the L2TP tunnel. The LAC may provide, to the multicast address, a request associated with initiating the L2TP tunnel. The request may be provided such that a plurality of L2TP network servers (LNSs) receives the request. The LAC may receive a set of responses to the request. The set of responses may be provided by a respective set of LNSs. The plurality of LNSs may include the respective set of LNSs. The LAC may select, based on the set of responses, a particular LNS, of the respective set of LNSs, with which to set up the L2TP tunnel.

Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.
