Embodiments of the present invention provide a method and system for orchestrating services in a service chain. Establishing a first group with a plurality of active services and a second group with a plurality of standby services. Upon receiving an error notification of a crash in a service, moving the plurality of active services from the first group to the second group, and moving the plurality of standby services from the second group to the first group. Upon receiving an updated service group of the plurality of active services of the first group, moving the plurality of active services from the first group into the second group, and moving the plurality of standby services from the second group to a repository.

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

Techniques are disclosed for implementing emergency calling with a telephony application. In some examples, an application that executes on a user device provides voice communication functionality. Where a user attempts to contact an emergency number via this application (e.g., 911), the application can first determine whether the application is executing on a mobile phone or on a tablet. Where the application is executing on a mobile phone, the application can invoke a telephone dialer functionality provided by the mobile device to call the emergency service. Where the application is executing on a tablet, the application can access the emergency service via a uniform resource name for the emergency service.

Method, for use in a telecommunications network, of selecting from a plurality of composite services a composite service to be executed in response to a network event. Each composite service has associated therewith criteria including a Boolean expression determining whether or not the composite service may be executed in response to the network event. The method comprises composing, for the network event, for each composite service an indicator indicating a) whether or not the criteria for that composite service are met by the network event, and b) a measure of conformity of the network event with said criteria. The method further includes selecting the composite service having associated therewith the indicator indicating that the criteria are met, and indicating closest conformity.

Methods, systems and devices for network congestion control exploit the inherent burstiness of network traffic, using a wave-based characterization of network traffic and corresponding multiplexing methods and approaches.
