Data transfer control system and method

摘要

Transfer of data files, such as large files for digital media, is performed through the intermediary of a gateway communication manager (GCM) that resides in an interface zone between external clients and an internal network. The external clients are registered with the GCM and request transfer of data files to the internal network. The GCM identifies a transfer agent to handle the transfer, and allocates a portion of shared bandwidth. If insufficient bandwidth is available or transfer agents are unavailable, the requested transfer may be placed in a queue and transfer occurs when bandwidth and agents can accommodate the request. The GCM may prioritize and re-prioritize transfers, such as based on the sender, content, and so forth. Multiple GCMs may manage transfers for external clients, and shared logs may be maintained to permit flexibility in management by the GCMs.

主权项

1. A data communications control method comprising:
receiving a request to transfer a communication, such request communicated by an external client to a gateway connection manager in an interface zone between the external client and an internal network; assigning a transfer rate for the communication; assigning a transfer agent to receive the communication; and receiving the communication in the interface zone if available bandwidth is sufficient for a minimum threshold transfer rate; and transmitting the communication to the internal network.
