A method of multicast data transfer including accessing a source address to a source location of mapped memory which stores source data, accessing multiple destination addresses to corresponding destination locations of the mapped memory, and for each of at least one section of the source data, reading the section using the source address, storing the section into a local memory of a data transfer device, and writing the section from the local memory to each destination location in the mapped memory using the destination addresses. Separate source and destination attributes may be provided, so that the source and each destination may have different attributes for reading and storing data. The source and each destination may have any number of data buffers accessible by corresponding links provided in data structures supporting the data transfer. The source data may be divided into sections and handled section by section.
