Abstract: According to an embodiment, a server device includes one or more processors and a first storage. The processors receive first data of transmission data from a transmitting device. The processors further receive second data of the transmission data, transmitted from the transmitting device in response to a transmission request. The processors deliver the first data and the second data to a receiving device. The first storage stores the first data and the second data. The processors delete at least one of the first data and the second data from the first storage according to a predetermined condition, and store data including at least a portion of the deleted data in a second storage.

Abstract: A server device includes one or more processors. The processors receive a plurality of transmission data from a transmitting device. The processors divide the plurality of transmission data into first data and second data. The processors transmit the first data to an external server device that delivers transmission data to a receiving device. The processors store the second data in a storage. The processors receive a transmission request for the second data from the receiving device or the external server device. The processors transmit the second data to the external server device in response to the transmission request.

Abstract: An information processing system includes a server device and one or more edge systems. The server device includes a memory, and one or more processors coupled to the memory and configured to: receive a plurality of first stream data to which first time information is associated from the edge systems; receive reference information in which second time information and the first time information corresponding to the selected first stream data are associated to each other, from the edge systems; receive an acquisition request of the first stream data corresponding to third time information expressed in the same format as the second time information; and identify the first stream data to which the first time information corresponding to the third time information is associated based on the reference information.

Abstract: A transmission device according to an embodiment includes one or more processors. The processors divide a plurality of pieces of transmission data to be transmitted into first data and second data. The processors transmit the first data to a server device configured to distribute the transmission data to a reception device. The processors store the second data in storage. The processors receive, from the reception device or the server device, a request for transmission of the second data. The processors transmit the second data to the server device in accordance with the request for transmission.

Abstract: According to an embodiment, a transmission device includes a first sending unit and a second sending unit. The first sending unit is configured to send, to a receiving device, one or more pieces of identification information identifying one or more pieces of transmission data. The second sending unit is configured to send, to the receiving device, determination information meant for determining whether or not to request transmission of the transmission data identified by the identification information.
