The systems and methods discussed herein provide for faster communications, particularly for high priority traffic, across a distributed network with multiple exit points to a Wide Area Network. Rather than simply routing traffic based on internal or external destination, an intelligent router may measure latency to an endpoint destination via multiple paths, both external and internal, and direct traffic accordingly. Steering high priority traffic via the internal connection to an exit point near the destination server, and then to the server via the external network, may be faster than simply forwarding the connection via the external network from the exit point closest to the source device. Additionally, to reduce bandwidth requirements of the nearby exit point and provide capability for higher priority traffic, low priority traffic may be redirected back via the internal connection and transmitted via a distant exit point.

Methods for systems are provided. In one aspect, a method for minimizing a network outage includes identifying one or more paths connecting a resource node of the network to an edge switch of one or more edge switches of the network. Each edge switch is connected to one or more endpoint devices to allow resources coupled to the resource node to be provided to the one or more endpoint devices. The method further includes calculating endpoint downtime costs corresponding to rebooting each of the common switches in the network. The common switches are present in all paths connecting the resource node to the edge switch. The calculated endpoint downtime costs corresponding to the one or more common switches are compared. One of the common switches with a highest endpoint downtime cost is identified as a candidate switch for redundancy based on the comparison.

The present application describes a path selection method and apparatus. The method may include obtaining a required latency of a service. The method may further include determining a target path for the service from m strict explicit paths based on the required latency, where a latency of the target path is less than or equal to the required latency, all the m strict explicit paths are unallocated paths, any subpath of a first strict explicit path in the m strict explicit paths exists in only the first strict explicit path, the first strict explicit path is any path in the m strict explicit paths, and m is an integer greater than or equal to 1. The present invention is applicable to the field of communications technologies and resolves at least a problem where a path computation element (PCE) cannot ensure that a path allocated to a service can meet a latency requirement of the service.

Method for generating a virtual representation of a coaxial network structure of a MoCA (Multimedia over Coaxial Alliance) network, which MoCA network comprises a plurality of node devices, including one network management device, wherein the node devices are interconnected through the coaxial network, the method includes determining a time lapse matrix having time lapse values T.sub.i,j representing propagation time through the coaxial network between node devices n.sub.i and n.sub.j, processing the time lapse matrix to establish a branch association for each node device with respect to the network management device, and storing virtual representation data of the coaxial network comprising the branch associations.

Described embodiments provide systems and methods for zone selection for distributed services. A device records latency data measured for interactions between each of a plurality of clients and a service hosted by servers in two or more zones. The device directs network communications from each of the plurality of clients to respective servers hosting the service based on zones assigned to each of the plurality of clients. The device assigns clients to zones based on the recorded latency data. For example, the device identifies a grouping for a client, determines whether the recorded latency data indicates that latency for clients in the grouping is increasing faster than a threshold rate, and selects, responsive to the determination, a zone indicated by a selected set of recorded latency data as lowest in latency.

A method performed by a digital Distributed Antenna System (DAS) for routing aggregated carriers received by at least one digital master unit of the DAS to at least one digital remote unit of the DAS. The method includes identifying the received aggregated carriers to be transmitted to a wireless communication device located in a coverage area served by the at least one digital remote unit, and routing the identified aggregated carriers through the DAS such that the carriers are transported to said at least one digital remote unit for transmission to the wireless communication device.

A satellite communication system includes a communication terminal, and a ground station. The ground station is configured to communicate with the communication terminal through a satellite communication path between the ground station and the communication terminal via a satellite. The ground station includes a diversity switch, and an electronic controller. The diversity switch is configured to switch the satellite communication path from a first satellite communication path to a second satellite communication path different from the first satellite communication path. The electronic controller is configured to determine whether a predetermined switching condition is satisfied based on signal attenuations of the first and second satellite communication paths. The electronic controller is further configured to control the diversity switch to switch the satellite communication path upon elapsing a first predetermined time period after determining that the predetermined switching condition is satisfied.

A communication management list generation device 20 generates a communication management list composed of communication management information including time of day information corresponding to a prescribed time of day and communication information indicating a communication process started at a prescribed time of day and not using the same path at the same time. The communication management list generation device is provided with: a determination means 21 for determining, regarding whether information on the communication process can be added to the communication information, each communication management information in descending order of time (early time first) corresponding to the time of day information; and an addition means 22 for adding information on the communication process to the communication information of the communication management information determined at a stage at which it was determined by the determination means 21 that addition is possible.

A switch-connected dragonfly network and method of operating. A plurality of groups of row switches is organized according to multiple rows and columns, each row including multiple groups of row switches connected to form a two-level dragonfly network. A plurality of column switches interconnect groups of row switches along respective columns, a column switch associated with a corresponding group of row switches in a row. A switch port with a same logical port on a row switch at a same location in each group along the respective column connects to a same column switch. The switch-connected dragonfly network is expandable by adding additional rows, an added row comprising a two-level dragonfly network. A switch group of said added row associated with a column being connects to an available port at an existing column switch of said column by corresponding added S path link with no re-cabling of the switched network required.

A device can receive, from a node in a core network, application identifiers associated with applications accessible by a first user device. The application identifiers can be associated with latency requirements. The device can obtain, from the first user device, a first packet associated with a first packet flow. The device can compare information regarding the first packet flow, and the application identifiers to determine that the first packet is destined for a low-latency application having a specified latency range. The device can identify a first low-latency bearer that satisfies the specified latency range associated with the low-latency application. The device can map the first packet flow to the first low-latency bearer, and communicate packets, associated with the first packet flow, using the first low-latency bearer. The packets can include data packets communicated between an entity hosting the low-latency application and the first user device, while bypassing the core network.
