1. A method comprising:
using a first operation request, generated by a requestor device, to communicate a data to a first network controller; and
using a second operation request, generated by the first network controller, to communicate the data from the first network controller to a second network controller communicatively coupled to a target memory, wherein at least one of the first operation request or the second operation request is a unified operation request comprising:
an operand identifying the data;
a destination memory address to store the data in the target memory; and
an operation code recognizable, by a corresponding recipient device, as a request to update an arrival indicator in the target memory responsive to arrival of one or more portions of the data at the target memory.
