摘要:
The invention relates to a system for routing ACARS messages to a plurality of transmission media, intended to be installed on board an aircraft. The system includes: a database containing a plurality of routing profiles, each profile comprising a list indicating a preference ranking for each transmission medium; selection means for extracting a routing profile identifier from an ACARS message sending request and for selecting a transmission medium according to the preference ranking thereof from the routing profile stored in the database corresponding to said identifier. The transmission medium thus selected is then used to transmit the message.

A path redundant, hardware efficient communications interconnect (1) has embodiments that can present true any-to-any interconnect capability for first and second pathways (2) and (3) and can utilize double throw switches (25) with or without single throw switches (24) perhaps in staged collectives of sub arrays (4), (5), (6), (9), and (10). A loop-back communications interconnect (22) can be accomplished by an interleaved sub array (26). A quadrilateral center stage sub array (21) can be combined with asymmetric side stage sub arrays for hardware savings that are tenths of a percent of a traditional interconnect and even present eight fold savings over prior reduced hardware interconnects.

Embodiments of the present invention generally relate to network communications. More specifically, embodiments relate to a system and method for switching data through a network. An embodiment of a switching system communicatively couples an external network to a wide area network. The system includes a plurality of edge switches communicatively coupled to the external network, a plurality of core switches communicatively coupled to the wide area network, and an interconnected matπx of switches communicatively coupled to the core switches and the edge switches and configured to forward communication traffic between the edge switches and the core switches.

An optical network system disclosed in an embodiment of the present invention contains a PE and a handover equipment located between the PE and a CE. The PE is adapted to provide optical network access for the CE. The handover equipment is adapted to disconnect a CE that finishes working at a handover time, and/or connect a PE with a CE that will work in a next time segment. The present invention also discloses a service handover method of optical networks, in which a handover equipment is preset between a PE and a CE, and CE information in mutually complementing services and corresponding working time segments are pre-stored. The method includes: (A) determining a handover time according to the stored working time segments; and (B) upon arrival of the handover time, the handover equipment disconnects a CE that finishes working according to the stored CE information and the corresponding working time segments; and/or connects a CE that needs to communicate in a next working time segment with a corresponding PE. Furthermore, the present invention discloses a handover equipment and a PE in an optical network. The present invention can reduce the ports occupied by the PE.

The present invention maintains calls during transfers between different types of subsystems, even when there is a bearer path interruption at the user element due to the original connection from the transferring-out subsystem being dropped before the new connection in the transferring-in subsystem is established. The call signaling leg toward the remote endpoint of the remote party is held, while the call signaling leg toward the user element is moved from the transferring-out subsystem to the transferring-in subsystem and a new bearer path is established via the transferring-in subsystem. During transfers with a bearer path interruption, a portion of the bearer path leading to the remote endpoint may be connected to a media resource function, which will provide an announcement to the remote party. Once the user element is accessible in the transferring-in subsystem, the bearer path is further transferred to the user element via the transferring-in subsystem.
摘要:
A router that includes a plurality of processors (SMPs) where there is 'affinity' between particular processors and particular interfaces: Each of the router's interfaces are assigned to one of the processors. A packet arriving at a particular interface will be handled by the processor having an affinity to that particular interface. If the packet's egress is on an interface assigned to the same processor, then the output process will also be handled by that processor. If the egress interface has an affinity to a different processor, then the packet is handed over to the other processor for egress. The data structures that must be retrieved from memory to handle a packet are often associated with the interfaces through which the packet passes. Thus, having a particular processor handle all the packets that pass through a particular interface insures that the data structures needed to handle the packets will more likely be stored in the processor's cache and less likely be the object of inter-processor lock contention.
摘要:
An interconnect structure (200) comprising a plurality of input ports (204) and a plurality of output ports (252) with messages being sent from an input port to a predetermined output port through a switch S (210, 224). Advantageously, the setting of switch S is not dependent upon the predetermined output port to which a particular message is being sent.
