Convergence Layer API<br />
create a new ingress point for bundle arrivals<br />
prepare the given link for transmission<br />
open a connection for the given contact<br />
try to send bundles queued on the given contact<br />
remove the given interface/link/contact<br />
• Though the abstraction is intended to be general, to date only<br />
two functional implementations (TCP and UDP)<br />
– API may (will likely) need to be extended to account for other transports<br />
• Other things of note:<br />
– May add an MTU (e.g. UDP limited to 16K max bundle)<br />
– Likely need abstractions for neighbor discovery, peer identification, etc.<br />
