Title:
DATA PACKET FORWARDING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/124009
Kind Code:
A1
Abstract:
Disclosed are a data packet forwarding method, device and system. The data packet forwarding method comprises: if a secure channel fails, saving received ageing flow table entries in an ageing flow table; determining whether a received reported data packet is matched with the ageing flow table entries in the ageing flow table; and if the reported data packet is matched with one ageing flow table entry in the ageing flow table, issuing the matched ageing flow table entry to an OpenFlow switch. In the present invention, during the failure of a secure channel, an OpenFlow switch proxy issues ageing flow table entries to facilitate an OpenFlow switch in forwarding data packets according to the ageing flow table entries, so that the problem in the prior art that the OpenFlow switch will be aged and lose a data exchange function during the failure of the secure channel is solved; and still can forward existing service flows continuously in the case where the flow table entries are aged.
