Abstract: A method and a server for dynamic work transfer are provided. The method includes following steps: regularly collecting and recording network resources of multiple nodes including a cloud node and multiple edge nodes in a network; receiving a request of a first job at a first time point, calculating a cost for configuring the first job to each node according to the network resource of each node at the first time point, and configuring the first job to a first target node; receiving a request of a second job at a second time point, calculating a cost for configuring the second job to each node according to the network resource of each node at the first time point, and determining a second target node suitable for configuring the second job and whether to transfer the first job; and accordingly configuring the second job and maintaining or transferring the first job.

Abstract: A method and a communication device for network address translation (NAT) traversal is provided. The method includes following steps. A NAT device information is exchanged between a communication device and another communication device. A relay connection is established between the communication device and the another communication device through a relay server. Whether it is feasible to establish a P2P connection between the communication device and the another communication device is determined according to the NAT device information. When it is feasible to establish the P2P connection between the communication device and the another communication device, an attempt to establish the P2P connection between the communication device and the another communication device is made. If the P2P connection is not established successfully, an attempt to establish the P2P connection between the communication device and the another communication device is made again.

Abstract: In an embodiment, a method comprises installing at least one application in a gateway, wherein the gateway is an anchor gateway and the at least one application corresponds to a profile; generating, by the anchor gateway, a gain value of the at least one application according to the profile; and determining, according to the gain value, whether to open or close the at least one application, or whether the at least one application is executed in the gateway or in another gateway. An application managing device and a system thereof are also provided.
