This may be because no bundle is currently being sent, or because the convergence layer can handle multiple simultaneous bundle transmissions. 16 = The link is busy, i.e. a bundle is currently being sent on it by the convergence layer and no more bundles may be delivered to the link. 32 = The link is in the process of being closed. 0 = Drop bundles 1 = Spool bundles until requested 2 = Execute the specified callback procedure Local bundle identifier. Whether the bundle is a fragment. Whether the bundle is an administrative record. Whether the bundle may be fragmented. Bundle priority or class of service. Whether bundle custody is requested. Whether the local node has custody of the bundle. Whether the destination is exactly one endpoint. Whether custody receipts are requested. Whether hop-by-hop reception receipts are requested. Whether hop-by-hop forwarding reports are requested. Whether end-to-end delivery receipts are requested. Whether bundle deletion reports are requested. Whether application acknowlegements are requested. Seconds since 1/1/2000. Subsecond sequence number. Bundle expiration time. Length of original bundle. Offset of fragment in the original bundle. Declared DTN node that "owns" the bundle (could be empty). Payload file name on local dtn node. Payload length. Actual length of payload available. For bundle fragments, offset into the file (todo) Extracted from owner Length of block contents Block contents Length of the block data (w/o preamble) Offset of first byte of the block data Whether or not this block is complete State of the transmission. How the bundle should be forwarded. Convergence layer for the contact. Convergence layer specific next hop string. Timestamp of last state update (seconds).

Whether the link is reliable. Name of the convergence layer. Minimum amount to wait between attempts to re-open the link (seconds). Maximum amount to wait between attempts to re-open the link (seconds). Seconds of idle time before the link is closed. Zero for always on links (i.e. they are never closed). Route priority. Forwarding behavior. Next hop link. Signals a new bundle arrival. Signals a bundle or bundle fragment transmission. Signals a failed transmission, which can occur if a link closes after a router has issued a transmission request but before the bundle is successfully sent. Signals a new bundle arrival that is destined for an external router. External routers access the bundle using the payload filename attribute. Signals bundle expiration. Signals a contact is up. Signals a contact is down. Signals the creation of a new link. Signals a link deletion. Signals availability of a link. ONDEMAND links still need to be opened (open_link_request) before they can be used. Signals a link as unavailable. Signals a new static route added from the DTN console. Signals a static route was deleted from the DTN console. Signals a bundle custody transfer. Signals a bundle custody transfer timeout. Signals a new application registration Signals a registration removal Signals a registration expiration Request that a link be opened. Request that a bundle with "bundleid" be sent on "link" with a particular "fwd_action". See bundleForwardActionType. Request that a bundle transmission be cancelled. Request that a router generated bundle be sent. Pay special attention to required and optional attributes. This message type requires that the bundle payload be base64 encoded. Query for information on links. Meta-information on links. Query for information on contacts. Meta-information on contacts. Query for information on static routes. Meta-information on static routes. Query for information on bundles (incl. custody bundles). Meta-information on bundles. Carry two or more router message on a single packet.
