The JEEP provides efficient, best-effort delivery of packets. In-order delivery is only guaranteed if there are no transmission errors over the SpaceWire link, e.g., bit errors or dropped packets, and there are no routing options which could cause a segmented packet to be transmitted or received out of order.
JEEP does not assure integrity of the delivered data. This means there is no error detection capability that checks for bit errors or missing packets. This was the tradeoff in order to make JEEP as efficient as possible. If data integrity is necessary then applications must use a reliable delivery protocol or apply error detection capability to their data prior to delivering it to JEEP.
This protocol provides buffer segmentation and reassembly to a SpaceWire link in order to fit the data to be transmitted into a specified network MTU size.
