[dpdk-users] packet guarantees

[amit sehas]

Does dpdk guarantee ordered delivery of packets?  Does the application have to implement retry mechanism?I would imagine that without a retry mechanism, it might be difficult for dpdk to implement ordering,which would seem to suggest that it does not guarantee ordered delivery of packets.
If dpdk does not guarantee order, I would think that it could lead to performance degradation in the applicationswhen they keep requesting older data which was out of order or dropped … in order to avoid that the applicationwould have to build packet reordering and retry mechanism ...
any help is appreciated ...thanks-Amit
