Data, and matched flow entry is found in flow tables at different levels, then according to the corresponding instruction of flow entry to input data packet
Carry out parsing and the conversion of agreement；
S32, interchanger store the result after every level-one flow table parses and converts into metadata；
After the completion of S33, protocol conversion, interchanger becomes data corresponding in metadata according to the rules integration of new agreement
New protocol headers；
New protocol headers after integration are inserted into input data packet by S34, interchanger, and characterizing source in input data packet
The label of agreement and purpose protocol type is deleted, to complete the process of protocol conversion.
Compared with prior art, the beneficial effects of the present invention are:
Incorporate network gateway design method disclosed by the invention based on the forwarding of agreement unaware is compared to big portion
Point traditional gateway approach, this method can be modified by controller on the basis of agreement unaware retransmission technique flow entry come
The conversion between existing protocol and the following new agreement occurred is preferably carried out, the programmability of gateway module is substantially increased
And scalability, the new agreement continuously emerged can be adapted on the basis of being changed without gateway, be conducive to adapt to the world one
The development of body network.
