Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
In the multi-channel protocol, after three handshakes of TCP, both sides of the protocol can negotiate one or more channels for transmitting signaling or data. For example, in FTP, an FTP client and a server first establish an FTP control connection, and then transmit data through a negotiated data transmission channel.
The FTP protocol uses by default two of the TCP ports, 20 and 21, with 20 ports for transmitting data and 21 ports for transmitting control information. In the FTP, there are active mode and passive mode, if the active mode is adopted, the data transmission port is 20 ports, and if the passive mode is adopted, which port is used is determined by negotiation between the server side and the client side.
In the active mode, the client is connected to the 21 PORT of the server, the client sends a PORT command to the server to tell the server that the server needs to adopt the active mode and open the PORT, and after receiving the PORT active mode command and the PORT number, the server is connected with the PORT opened by the client through the 20 PORT of the server to send data to the client.
In the passive mode, the client is connected to the 21 ports of the server, the client sends a PASV command to the server, the server locally opens one port, the opened port is informed to the client, and the client is connected to the opened port of the server for data transmission.
It can be seen that the server sends data to the client according to the port opened by the client in the active mode, the client sends data to the server according to the port opened by the server in the passive mode, and when sending data through the data channel, the obtained port is carried by a control command in the direction opposite to the data transmission direction.
In view of this, by establishing the session forwarding table entry associated with the data channel and the control channel and recording the session forwarding information of the control channel, the route query process can be reduced, and the forwarding efficiency of the packet can be improved. The session forwarding table entry queried by the data channel is created according to the control session of the control channel, so that the path consistency of the data channel and the control channel can be ensured, and the problem of service failure caused by the message sending error of the data channel is avoided.
The present application is described below with reference to specific embodiments and with reference to different application examples.
Referring to fig. 1, fig. 1 is a flowchart illustrating a message forwarding method according to an exemplary embodiment of the present application, where the method may be applied to a network device supporting a multi-channel protocol, and includes the following steps:
step 101: receiving a data message through a data channel;
step 102: inquiring a session forwarding table item according to the session characteristics of the data message, wherein the session forwarding table item is created based on session information of a control message received by a control channel, and the session information comprises the session characteristics of the control message in the direction opposite to that of the data message, an output interface and a target MAC;
step 103: and if the session forwarding table entry is inquired, forwarding the data message according to the outgoing interface and the target MAC in the session forwarding table entry.
In the multi-channel protocol, a network device receives a data packet through a data channel for transmitting data, and queries a session forwarding table entry according to session characteristics of the data packet, namely, quintuple information, a source IP, a destination IP, a source port, a destination port and a transport layer protocol.
As shown in table 1 below, a session characteristic of a data packet shown in an exemplary embodiment of the present application is:
| source IP | Destination IP | Protocol number | Source port | Destination port |
| IP2 | IP1 | Protocol 1 | Port 2 | Port 1 |
TABLE 1
The session forwarding table entry is created according to session information of a control message received by a control channel for signaling negotiation, and after the network device identifies a protocol of a target port in the control message, the network device generates the session forwarding table entry for data message matching according to a specific protocol. The session forwarding table entry records session information of the control message, the session information is created according to session characteristics of the control message with the direction opposite to that of the data message, and the reverse control message records the output interface and the destination MAC information and also records the session information.
As shown in table 2 below, a session table of a control packet according to an exemplary embodiment of the present application is shown, where the session table records session information of the control packet, where the session information includes five tuples of packets in two directions of a session and fast forwarding information:
| source IP | Destination IP | Protocol number | Source port | Destination port | Outlet interface | Destination MAC | Direction |
| IP1 | IP2 | Protocol 1 | Port 1 | Port 2 | Interface 1 | MAC1 | Forward direction |
| IP2 | IP1 | Protocol 1 | Port 2 | Port 1 | Interface 2 | MAC2 | Reverse direction |
TABLE 2
The session forwarding table entry records session information of a control packet in a direction opposite to that of the data packet, and is a session forwarding table entry shown in an exemplary embodiment of the present application as described in table 3 below:
| source IP | Destination IP | Protocol number | Source port | Destination port | Outlet interface | Destination MAC | Direction |
| IP2 | IP1 | Protocol 1 | Port 2 | Port 1 | Interface 2 | MAC2 | Reverse direction |
TABLE 3
If the corresponding session forwarding table entry is matched according to the session feature of the data message, the data message can be forwarded according to the outgoing interface and the destination MAC recorded in the session forwarding table entry.
For example, according to the session feature lookup table 3 of the data packet in table 1, a corresponding session forwarding table entry is queried, and the data packet is forwarded according to the egress interface and the destination MAC in table 3.
In an embodiment shown, if a session forwarding entry is queried, recording session information in the session forwarding entry into a data session corresponding to a data channel, and adding a data session identifier; and updating the data session, and forwarding the data message based on the updated session information.
As shown in table 4 below, for an updated data session table shown in an exemplary embodiment of the present application, a master identifier is added to the data session:
| source IP | Destination IP | Protocol number | Source port | Destination port | Outlet interface | Destination MAC | Direction | Identification |
| IP2 | IP1 | Protocol 1 | Port 2 | Port 1 | Interface 2 | MAC2 | Reverse direction | master |
TABLE 4
Furthermore, when receiving a data message corresponding to the session feature in the data session, judging whether the user opens the session forwarding mode; if yes, judging whether the data session has a data session identifier; if yes, the data message is forwarded according to the outgoing interface and the destination MAC in the data session.
For example, if a data packet is received, it is first queried that there is no corresponding data session according to the session characteristics, and if not, it means that the packet is received for the first time, a corresponding data session may be created. And then inquiring the session forwarding table entry, recording the session information in the session forwarding table entry into the data session, adding a data session identifier, finishing the updating of the data session at the moment, and forwarding the data message based on the updated session information.
If the corresponding data session is inquired, it is stated that the data message is not received for the first time, and the data message can be forwarded according to the information recorded in the data session. Judging whether a network device opens a session forwarding mode or not, checking session forwarding only if the session forwarding mode is opened, judging whether a data session is added with a data session identifier or not after the session forwarding mode is opened, if so, checking the data session for data message forwarding, and inquiring an output interface and a target MAC (media access control) forwarding data message recorded in the data session.
It should be noted that before querying the session forwarding table entry according to the session characteristics of the data packet, the session characteristics of the data packet received through the data channel are obtained, whether a data session corresponding to the data channel exists is queried based on the session characteristics, and if a data session corresponding to the data channel is not queried, a data session corresponding to the data channel is created.
If the data message is received for the first time, the data session is not established in the network equipment, and a session table of the data session can be established, so that the message can be directly forwarded according to the session table of the data session when the data message is received next time. If the corresponding session table exists, it indicates that the network device has received the packet of the data session before, and the data packet can be quickly forwarded directly according to the output interface and the destination MAC in the session table.
In an embodiment, the session information of the control packet is obtained by receiving the control packet through the control channel. The session information includes session characteristics of a control message in a direction opposite to that of the data message, and an ingress interface and a source MAC of the control message, the ingress interface included in the session information is used as an egress interface, the source MAC is used as a destination MAC, and a session forwarding table entry corresponding to the data message in the direction opposite to that of the control message is further created.
After receiving a control message of a control channel, creating a session forwarding table according to the control message, for example, in ftp, no matter in an active mode or a passive mode, the direction of initiating a data channel message is opposite to the direction of the control message carrying an ingress interface and a source MAC.
It should be noted that before the session information of the control packet is obtained, the control session corresponding to the control channel may be queried based on the session characteristics of the control packet, and if the control session is not queried, the control session corresponding to the control channel is created based on the session information, and it is determined whether the user has opened the session forwarding mode. If yes, adding a session forwarding identifier in the created session information of the control session, and recording an input interface and a source MAC of the control message as the session information into the control session.
In one embodiment shown, if the control session is queried, further querying whether the session information of the control session has a session forwarding identifier; if so, using the input interface contained in the session information as the output interface and the source MAC as the destination MAC, and further creating a session forwarding table entry corresponding to the data message with the opposite direction to the control message.
After the session forwarding mode is opened on the network equipment, the message can be forwarded by checking the session without checking a route, so that after the session forwarding mode is opened, a session forwarding identifier can be added to the session of the control message, the interface and the source MAC information are recorded, and when the message with the same session information is received next time and is matched with the corresponding session, the message is directly forwarded according to the session information.
For example, after a session is created for a forward packet of a control channel and a session forwarding identifier is added, a reverse packet of the control channel is matched with the session created for the forward packet during session query, the session forwarding identifier is checked, and a session forwarding mode is started by a network device, the reverse packet can directly perform packet conversion on an input interface and a source MAC in the session created for the forward packet, the reverse packet takes the input interface as an output interface, and the source MAC as a destination MAC for forwarding.
It can be seen from the above embodiments that, by establishing the session forwarding table entry associated with the data channel and the control channel, and recording the session forwarding information of the control channel, the route query process can be reduced, and the forwarding efficiency of the packet can be improved. The session forwarding table entry queried by the data channel is created according to the control session of the control channel, so that the path consistency of the data channel and the control channel can be ensured, and the problem of service failure caused by the message sending error of the data channel is avoided.
