Classification: CPC H | IPC H

Claim 13:
14. A network node comprising:
a processor and memory configured to;
receive a sequence of packets from a first client, the sequence of packets each having a same flow;
facilitate a secure tunnel between the network node and a hub and to assign a first flow identifier to the sequence of packets; and
encapsulate a first start packet of the sequence of packets in a wrapper, the wrapper including the first flow identifier;
send the encapsulated first start packet of the sequence of packets from the network node to the hub through the secure tunnel, and to receive an error message from the hub, the error message including the first flow identifier and an error code;
facilitate a second secure tunnel between the network node and the hub in response to receiving the error message and to assign a second flow identifier to the sequence of packets;
encapsulate a second start packet of the sequence of packets in a wrapper, the wrapper including the second flow identifier;
send the encapsulated second start packet of the sequence of packets from the network node to the hub through the second secure tunnel;
convert fields of a header of a third packet of the sequence of packets to a header format that has fewer bytes to form a reduced third packet and to encapsulate the reduced third packet in a wrapper that includes the second flow identifier; and
send the encapsulated reduced third packet from the network node to the hub through the second secure tunnel,
wherein sending the encapsulated second start packet comprises sending the encapsulated second start packet without removing fields from a header of the second start packet.
