Abstract: A method for transmitting an application programming interface API request includes receiving, by a first API gateway, a first API request; obtaining, by the first API gateway, a first forwarding label corresponding to the first API request, where the first forwarding label includes a first target security domain identifier, and a security domain identifier of the first API gateway is different from the first target security domain identifier. The method also includes determining an address of a second API gateway according to a mapping relationship between the first target security domain identifier and the address of the second API gateway. The method additionally includes sending the first API request to the second API gateway based on the address which is a next-hop API gateway of the first API gateway that sends the first API request to an API gateway corresponding to the first target security domain identifier.

Abstract: A method for managing file system replication can include: collecting event data associated with file system events, each of the file system events indicative of a modification of at least one file at a first file system location; for each of the file system events, generating at least one file system action to apply the modification of the at least one file at the first file system location to at least one corresponding file at a second file system location; storing the at least one generated file system action in an action buffer; identifying dependencies between file system actions in the action buffer; and scheduling the file system actions in the action buffer for execution based on the dependencies.

Abstract: The present disclosure is drawn to methods and systems for resource enforcement in a distributed system. At least one first host of the system has an enforcement agent configured to trigger a master enforcement controller in response to the first host running a task requiring access to a distributed resource. The master enforcement controller obtains identification information regarding the distributed resource and transmits an enforcement command to other hosts of the distributed system involved in providing the distributed resource. The enforcement command is received by enforcement agents on each of the involved hosts and triggers a slave enforcement controller on each of the involved hosts. The slave enforcement controllers locally enforce a resource quota for the distributed resource.

Abstract: A communications system which includes a first data center and a second data center, where the first data center includes a first message proxy, a first routing proxy, a service server, and a storage server and configured to receive a first message from an application running on the service server, add routing information to the first message to generate a second message when the first message is processed by the second data center, and store the second message in a public area of the storage server, where the public area is configured to store a message processed by the second data center. The first routing proxy is configured to obtain the second message from the public area, and send the second message to the second data center based on the routing information.
