The disclosure relates to an Edge Cloud Platform (ECP) and a method executed in the ECP, for providing a low-latency, distributed, multi-user application. The method comprises determining a first location of a first group of users requesting access to the multi-user application and deploying the multi-user application in a first Point of Presence (PoP) in a first Service Provider (SP) domain operative to serve the first group of users. The method comprises determining a second location of a second group of users requesting access to the multi-user application and deploying a proxy of the multi-user application in a second PoP in a second SP domain operative to serve the second group of users. The method comprises, upon determining that a Software License Agreement (SLA) exists between the first and second SPs, establishing a tunnel for linking the multi-user application and the proxy of the multi-user application, thereby providing the low-latency.

A network path selection method and a network node device using the same are disclosed. The network path selection method includes: determining whether a first uplink time parameter table is received from the first relay node device and whether a second uplink time parameter table is received from the second relay node device; when the first uplink time parameter table is received from the first relay node device and the second uplink time parameter table is received from the second relay node device, calculating a first estimated uplink time parameter according to the first uplink time parameter table and a second estimated uplink time parameter according to the second uplink time parameter table; and determining to connect to a gateway via one of the first relay node device and the second relay node device according to the first estimated uplink time parameter and the second estimated uplink time parameter.

Systems and methods for routing trade orders based on exchange latency are disclosed. An example method includes measuring a first latency associated with a first exchange based on a processing time of a first trade order; and routing a second trade order from a trading device to one of the first and a second exchange based on the first latency.

A set of connections is established, continuously evaluated and maintained between two endpoints of a computer network for use in transmitting information flows in a more efficient and controlled manner. New connections are established and existing connections are terminated in a continual search for connections with better and/or different performance characteristics. Each connection may utilize the same or a different path through the network and may have performance characteristics that change over time. Several paths can be used simultaneously for a given information flow to improve network metrics including: throughput, transaction time, data consistency, latency and packet loss. Flows of information can be broken into one or more sub-flows and sub-flows can be assigned to one or more active connections. Furthermore, dynamic decisions regarding how flows are broken up and how they are assigned to connections can be made in response to network conditions. Through the use of these connections, a reduced cost can be offered and application QoS/QoE can be guaranteed, allowing existing networks such as the public Internet to provide an enterprise class connection, which can be used to accelerate enterprise cloud adoption without modifying the present Internet infrastructure.

A method for determining path health to conduct a plurality of Input-Output (IO) operations along a healthy path in a network is provided. The present invention may include receiving an IO request from a user and sending the received IO request on a first path. The present invention may include determining a first IO response has exceeded a threshold time on the first path. The present invention may include determining the first path has degraded based on the exceeded threshold time. The present invention may include generating a duplicate IO request and sending on a second path. The present invention may include receiving the duplicated IO response before receiving the original IO response. The present invention may include determining a health state associated with the slower path. The present invention may include refreshing a path state machine based on the determined health state associated with the slow path.

A management device includes: a memory; and a processor coupled to the memory and configured to: acquire a transfer condition between a first processing device that backs up data related to a task, and each of a plurality of second processing devices that are candidates for a rearrangement destination of the task; and determine, as a processing device of the rearrangement destination, a processing device that satisfies a delay requirement related to delay time of processing in which the transfer condition is set for the task, among the plurality of second processing devices.

Examples include generating a Precision Time Protocol (PTP) packet for a first nexthop in an Equal Cost Multi-Path set and sending the PTP packet to the first nexthop. Examples also include receiving a response from the first nexthop that identifies a time delay associated with a route to the first nexthop and updating the ECMP based on the time delay.
