Abstract

See full text

A system includes a network tunnel, an ingress network device coupled to send packets via the network tunnel, and an egress network device coupled to receive packets sent via the network tunnel. The egress network device is configured to provide information to the ingress network device. The information indicates whether a packet transmitted from the ingress network device to the egress network device was dropped in the network tunnel. The ingress network device can retransmit the packet to the egress network device if the packet is dropped in the network tunnel.
