MULTICAST TRANSPORT

摘要

One or more techniques and/or systems are provided for multicast transport configuration, for multicast transport, and/or for fault policy implementation. In an example, a multicast component may receive a data copy request from an application to copy data to multiple destinations. A scheduler component may create a transport schedule specifying an order with which to facilitate data copy operations across transports, such as heterogeneous transports, to the destinations. A dispatcher component may apply application specified transport modifiers to the data copy operations (e.g., a modification to a quality of service for a transport). The dispatcher component may facilitate the data copy operations and provide operation result information to a policy agent. The policy agent may provide notifications of data copy operation statuses from the operation result information and/or may implement a fault policy (e.g., a retry on a different transport) for a data copy operation that experienced a fault.

1. A system for multicast transport, comprising:
a processor; and memory containing instructions which when executed by the processor implement at least some of:
a multicast component comprising:
a scheduler component configured to:
receive a data copy request from an application to copy data to a first destination and a second destination;identify a first transport over which first data of the data copy request can be transported to the first destination;identify a second transport over which second data of the data copy request can be transported to the second destination, the second transport different than the first transport;evaluate transport status information to determine a first transport status of the first transport and a second transport status of the second transport; andcreate a transport schedule for a first data copy operation associated with the first data and a second data copy operation associated with the second data based upon the first transport status and the second transport status; anda dispatcher component configured to:
facilitate the first data copy operation over the first transport based upon first transport characteristics of the first transport and the transport schedule; andfacilitate the second data copy operation over the second transport based upon second transport characteristics of the second transport and the transport schedule.
