Abstract:

A method and network interface logic for providing an embedded checksum in a packet transferred over a packet network. The packet network comprises a plurality of interconnected, directly-attached computers operative to provide data fidelity between any neighboring pair of such computers at least as robust as such data fidelity between any non-neighboring pair of such computers. Each computer comprises packet storage means and network interface means. Such a packet is sent directly onto the packet network from the packet storage means of a source computer using its network interface means. The packet is received from the packet network and transferred directly into the packet storage means of a sibling computer using its network interface means. Such an embedded checksum is associated with the packet at the sibling computer with the embedded checksum being calculated by at least one of the source computer or the sibling computer based on substantially the entire packet for validating error-free receipt.
