Abstract: A module monitors an arrival time of a frame at a node that selectively transmits frames from different flows in different time windows. The module determines whether the arrival time is within a time window and generates a signal in response to the arrival time being outside of the time window. In some cases, the frame is received at an ingress port of the node and the arrival time of the frame is recorded in an event database in response to receiving the frame at the ingress port. The arrival time of the event is accessed from the event database and this information is used to determine whether the arrival time is within the time window. The time window can be modified in response to the arrival time being outside the time window.

Abstract: A node is configured for deployment in an optical network. The node includes an analog switch for routing an optical packet between input ports and output ports. The node also includes digital processing circuitry configured to generate first configuration information based on the optical packet prior to providing the optical packet to the analog switch. The analog switch is configured to route the optical packet between the input ports and the output ports based on the first configuration information in response to the optical packet arriving at the node in a first time interval. The optical packet is not processed by the digital processing circuit or results of processing are not used to configure the analog switch during a second time interval. The analog switch routes the optical packet between the input and output ports based on second configuration information during the second time interval.

Abstract: A node is deployed along a path between a master device and a slave device. In some cases, the path includes additional nodes. The node includes a plurality of queues configured to be associated with a corresponding plurality of flows. A first queue of the plurality of queues is configured to be associated with a first flow that conveys timing messages for synchronizing the master device and the slave device. A scheduler is configured to schedule messages from the first queue during an extended time window that encompasses expected arrival times of a first set of timing messages in the first flow. The node reverts to normal behavior in response to completing processing of the first set of timing messages. During normal operation, the node schedules messages from the first queue during a default time window that is shorter than the extended time window.

Abstract: Known telecommunication systems comprising a network with fixed stations and comprising mobile stations for sending identification codes to said network via fixed stations and for allowing mobile communication to subscribers using said mobile phones, with said network comprising a database for storing subscriber-information, can offer more services by storing in said database subscriber-information related to identification codes for allowing subscriber-information to be exposed to further subscribers, with update codes being used for updating said subscriber-information. Preferably, said update codes define the amending of subscriber-information already stored or the storing of new subscriber-information, and an analyser is used for analysing subscriber-information and in dependence transmitting messages. Further, purpose codes are used to define which parts of said subscriber-information is to be analysed and/or to be amended and/or to be exposed, and location codes are introduced to introduce borderlines.
