A reliable data transfer architecture for a space-based reconfigurable protocol chip

In this paper, we present an architecture for reliable data transfers for space-based applications. In particular, we examine a network interface card (NIC) architecture, a reliable link layer approach based on hybrid automatic-repeat-request (ARQ) scheme, and then consider the corresponding handshaking associated with file transfers. We present results on the performance of our methodology and an implementation strategy for incorporation of the mechanism into a reconfigurable protocol chip architecture
