For computing (Deal) portal server and stores processor (DB) portal server, in its routing table also for each smart machine of access book server cluster, record this smart machine the network layer address of this platform, with the corresponding relation of this smart machine at the temporary ip address of public network side and interim udp port number.For computing (Deal) portal server or stores processor (DB) portal server, network L3 address (ST_IOT_MSG_L3_ADDR structure) information of the smart machine in the internet message bag (being the message bag that smart machine directly sends) that beyond also can recording at ordinary times in this plateform system overall situation SDN network definition list, come (outside), arrive address resolution protocol (Address Resolution Protocol with the corresponding relation of sending out message opposite end sender's (being smart machine) link physical address (ST_IOT_MSG_L2_ADDR structure) information, abbreviation " ARP ") in table.

Below internet message bag routing forwarding process (algorithm) in present embodiment is described:

This Internet of Things routing function and flow process of each node (server or computer) that interconnect in platform is similar,, travel through every the record of routing table of oneself, if the network address mask (ulAddrTypeMask) of the L3 address style (ulAddrType) in the destination network addresses in internet message bag (ST_IOT_MSG_L3_ADDR structure) and this record (ST_IOT_ROUTE_TBL_ITEM structure) equates, and the smart machine in the destination network addresses in internet message bag (ST_IOT_MSG_L3_ADDR structure) indicates address digit (stObject) between the destination address section minimum value (stNetAddrFrom) and destination address section maximum (stNetAddrTo) of this record (ST_IOT_ROUTE_TBL_ITEM structure), find route, this internet message bag is by the down hop link No. (PhyLinkID) of this record (ST_IOT_ROUTE_TBL_ITEM structure), be sent to the object link physical address stNextSkip of the down hop of this record (ST_IOT_ROUTE_TBL_ITEM structure).When routing table lookup less than expectation record time, message abandons (this kind of situation can not occur under normal circumstances).

When computing (Deal) portal server or stores processor (DB) portal server are searched routing table result while being default route, be that L3 address style (ulAddrType) in the destination network addresses (ST_IOT_MSG_L3_ADDR structure) in internet message bag is 0 o'clock, if find it is while mailing to the message of smart machine itself, will search ARP table, obtain the link opposite end physical address that this smart machine is corresponding, and by the socket link No. of WAN mouth side, send.

By this routing forwarding algorithm, internet message bag is multi-hop step by step, finally jumps to destination, completes the route forwarding function of whole internet message bag.Do not expect internet message bag and the automatic discard processing of abnormal bag received.

For example: example 1, smart machine A need to send an internet message bag to smart machine B, smart machine A sends an internet message bag to its host, to belong to computing portal server is computing (Deal) portal server S1, in the destination address of internet message bag, L3 address style is 0, the address digit that sign address digit is B; S1 finds that in destination address, L3 address is 0, revise its address style is 1 temporarily, other address informations are constant, then according to routing table lookup next hop address, see server or the whether one's own cluster of computer that next hop address is corresponding, if belonged to, look into ARP table, find temporary ip address and the udp port of smart machine B, internet message bag is sent to smart machine B, completed the communication between smart machine A and smart machine B; If do not belonged to, L3 address is changeed back into 0, it is computing (Deal) portal server S2 that continuation sends to the host of B to belong to computing portal server according to the next hop address that route went out just now, S2 is same is transmitted to smart machine B through above-mentioned route (searching ARP table), has just completed the communication between smart machine A and smart machine B.

Such as sending an internet message bag, 2: one smart machine A of example act on behalf of A1 to the calculating of its calculation services function at this plateform system again, A sends an internet message bag, and to its host, to belong to computing portal server be computing (Deal) portal server S1, in the destination address of internet message bag, L3 address style is 1, the address digit that sign address digit is A, every record of routing table of S1 traversal oneself, if in the L3 address style of destination address and routing table, the network address mask of certain record equates in internet message bag, and the smart machine in destination address indicates address digit between the destination address section minimum value and destination address section maximum of this record, find route, this internet message bag is by the down hop link No. of this route record, be sent to the object link physical address of the down hop of this route record, be transmitted to the calculating participant computer at down hop A1 place, this calculating participant computer-internal is given to the calculating Agent object A1 of the calculation services function of A again, through this 2 jumping, just completed smart machine A and the communication between A1 is acted on behalf of in its calculating in this plateform system calculation services function.

3: one smart machine A of example act on behalf of A1 in the calculating of the calculation services function of this plateform system and send an internet message bag to smart machine A for another example, A1 sends an internet message bag, and to the host of A, to belong to computing portal server be computing (Deal) portal server S1, the above-mentioned routing forwarding of S1 process is to smart machine A, so 2 jump through this, just completed smart machine A and the communication between A1 is acted on behalf of in its calculating in this plateform system calculation services function.

And, in present embodiment, this Internet of Things interconnect plateform system can guarantee any internet message bag through this plateform system be all legal (identity is legal), complete (former state), safety (maintaining secrecy), only have between smart machine and pass through the internet message bag of direct UDP communication port, its fail safe is just by resolving through consultation voluntarily between smart machine.Remarks: the process of establishing of the direct UDP communication port between smart machine is via this plateform system, so the direct UDP communication port between smart machine itself is all legal passages of both sides' identity, just data integrity (former state) and the fail safe (maintaining secrecy) on this passage, resolve through consultation between the smart machine by these passage two ends voluntarily.

The fail safe of this plateform system communication has following 3 aspects: the identity legitimacy (digital certificate) of communicating pair is, the confidentiality (data encryption) of the integrality of Content of Communication (former state, do not destroy, do not distort etc., data signature), Content of Communication mutually.This plateform system adopts the famous RSA unsymmetrical key enciphering and deciphering algorithm of industry, and following mechanism is guaranteed above-mentioned 3 aspects.

Each smart machine that accesses this platform has RSA private key password and the RSA public key cryptography of oneself; Plateform system also has RSA private key password and the RSA public key cryptography of oneself.This plateform system has been stored the RSA public key cryptography of each smart machine, outwards discloses the RSA public key cryptography of this plateform system side simultaneously.Transmit leg A(smart machine side, or this plateform system side) to this plateform system side of recipient B(, or certain smart machine side) send internet message bag encryption and decryption process as follows:

A sends internet message bag M to B, first with the private key password Da of A, internet message bag M content is encrypted, and produces ciphertext Da (M); With the public key cryptography Eb of B, carry out the 2nd encryption again, produce ciphertext Eb (Da (M)), then send to B.

In the middle of ciphertext Eb (Da (M)), through Internet network, middle possibility is monitored, quilt is intercepted and captured, pretended, and content is tampered etc., finally may arrive recipient B.

B receives after this ciphertext, first with the private key password Db of B, deciphers for the first time, restores ciphertext Da (M); With the public key cryptography Ea of A, decipher for the second time again, obtain internet message bag original text M.

By this process, can be found out, transmit leg A has guaranteed that recipient must be B, and recipient B has also guaranteed that transmit leg must be A, and A cannot deny and be not that it is sent out, so communicating pair identity is authenticated; If internet message bag M is intercepted and captured by " false A " the internet message bag of A to B that disguise oneself as in transmitting procedure, " false A " do not know the private key password of A, so cannot pretend this internet message bag (thereby or not being that A is abandoned by B because of transmit leg after camouflage out); If internet message bag M is intercepted and captured in transmitting procedure, destroyed or modification, thereby recipient cannot parse and abandon, problem changes the situation of internet message packet loss (guaranteeing the repeating transmission of internet message bag by mechanism such as re-transmissions) into, thereby has guaranteed the integrality requirement of internet message bag; After internet message bag M sends out, because be to have used the private key password of A and the public key cryptography of expectation recipient B to encrypt, so only have expectation recipient B just can decrypt, guaranteed the confidentiality of Content of Communication.As can be seen here, this mechanism has met the communications security requirements such as confidentiality (data encryption) of the identity legitimacy (digital certificate) of mutual communicating pair, the integrality of Content of Communication (former state, do not destroy, do not distort etc., data signature), Content of Communication.

Although pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and described, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
