Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0024] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0025] The embodiments of the present application provide a flow forwarding method of a cross-flow device, the method is applied to a programmable cross-flow device. The cross-flow device exists in a CLOS cross architecture in terms of device form, including a plurality of service cards and switch cards, and the output of the flow accessed by one service card can be on another service card or a plurality of service cards, Figure 1 A CLOS cross-flow device architecture chassis schematic diagram is shown.

[0026] Referring to Figure 2 As shown, the method mainly includes the following steps:

[0027] Step S202, after detecting the access of the flow information, the flow information is added to a private message header, and the private message header is encapsulated to an original message to obtain a to-be-forwarded message.

[0028] Step S204, the to-be-forwarded message carrying the flow information is forwarded to a switch card.

[0029] Step S206, based on the switch card, the to-be-forwarded message is forwarded for a second time to a target service card.

[0030] Step S208, the to-be-forwarded message forwarded to the target service card is subjected to private message header stripping processing, and the stripped original message is output to a target port of the target service card.

[0031] The flow forwarding method of the orthogonal flow splitting device provided by the embodiments of the present application can realize self-defined control flow of message analysis, forwarding, message modification and the like through programmability of the data plane of the switching chip, and no longer depends on the designers of the chip, thereby realizing reconfiguration of the message analysis, forwarding and the like of the entire switching chip by the user.

[0032] For the convenience of understanding, the flow forwarding method of the orthogonal flow splitting device provided by the embodiments of the present application is described in detail below.

[0033] In an optional embodiment, after detecting the access of the flow information, the flow information is added to the private message header, and the private message header is encapsulated to the original message to obtain a to-be-forwarded message. In the specific implementation, the following steps 1.1) to 1.3) can be included:

[0034] Step 1.1), after detecting the access of the flow information, it is judged whether the flow information is cross-board card flow.

[0035] Step 1.2), if the flow information is cross-board card flow, the flow information is added to the private message header based on the cross-board card information of the target port, and the private message header is encapsulated to the original message to obtain a to-be-forwarded message.

[0036] Step 1.3), if the flow information is non-cross-board card flow, the flow information is evenly output at one or more output ports of the current service card.

[0037] Further, when the flow information is cross-board flow, the above-mentioned to-be-forwarded message carrying the flow information is forwarded to the current service card when the to-be-forwarded message carrying the flow information is forwarded to the backboard of the switching card.

[0038] In an optional embodiment, before the to-be-forwarded message carrying the flow information is forwarded to the switching card, the above-mentioned method further includes: performing matching of the private message header on the current service card, and when the matching hits the flow information that needs cross-board card flow, the flow information is evenly forwarded to the current service card and the backboard port of the switching card.

[0039] Further, after the flow information reaches the target service card through the backboard, the private message header information in the flow information is matched on the target service card, and is output from the specified output port after the matching hits.

[0040] In an optional embodiment, the encapsulation format of the private message header includes a fixed field and a cross-board information field, as shown in FIG. Figure 3

[0041] Figure 4 ​A system structure schematic diagram of orthogonal split-flow device access flow cross-board forwarding is shown, and the system comprises a self-defined private message header information marking unit, a self-defined private message header backboard forwarding unit, a self-defined private message header switch card forwarding unit, a self-defined private message header message output unit and a self-defined private message header automatic stripping unit.

[0042] In the execution of the above method, in combination with the system, the following steps 2.1) to 2.5) can be included:

[0043] Step 2.1), after the flow is accessed from one of the service card panel ports, the information of the output port of the flow cross-board forwarding is added to the user-defined private message header by the self-defined private message header information marking unit, the private message header is encapsulated into the message, and then the flow is forwarded together;

[0044] Step 2.2), after the self-defined private message header encapsulation of the access flow cross-board forwarding is completed, the flow is evenly forwarded to the backboard of the current service card and the switch card by the self-defined private message header backboard forwarding unit, and the first cross-board forwarding of the flow is completed;

[0045] Step 2.3), after the access flow is cross-board forwarded to the switch card, the flow output to the backboard port of the corresponding service card is output by the self-defined private message header switch card forwarding unit, and the second cross-board forwarding of the access flow is completed;

[0046] Step 2.4), after the access flow is cross-board forwarded to the target service card, the access flow is finally output to the corresponding output port by the self-defined private message header message output unit;

[0047] Step 2.5), when the access flow is output at the output port of the target service card, the self-defined private message header is also carried, and at this time the self-defined private message header needs to be output stripped by the self-defined private message header automatic stripping unit to output the original message.

[0048] Specifically, in one embodiment, after the flow is accessed from the service card panel port, the flow needs to be forwarded to a target port or evenly output to multiple target ports, if the flow is not cross-board flow, it is directly output from the board card, and if it is cross-board flow, the cross-board card information of the target port needs to be encapsulated in the self-defined message header.

[0049] After the custom packet header encapsulation of the cross-board target port information is completed, the private packet header needs to be matched on the current service card. When the matched traffic is the traffic that needs to be cross-boarded, the traffic is evenly forwarded to the backboard port of the current service card and the switching card to complete the first cross-board forwarding of the access traffic. If the traffic is directly output on the current service card, the private packet header does not need to be encapsulated, and the traffic can be directly output from one port or multiple ports.

[0050] After the traffic is cross-boarded to the switching card, the private packet header information needs to be matched on the switching card. After the matching, the traffic is evenly forwarded to the backboard port of the switching card corresponding to the service card slot, so that the second cross-board forwarding of the access traffic is completed.

[0051] After the traffic reaches the target service card through the backboard, the private packet header information in the traffic needs to be matched on the target service card. After the matching, the traffic is output from the specified output ports.

[0052] When the access traffic is output from the target output port, the private packet header needs to be automatically stripped during the output, so that the normal output of the access traffic from the output port of the current access board card and the output port of the cross-board service card is realized.

[0053] In summary, the embodiment of the application can realize the output of the traffic from a single port or multiple ports of the target service card after the cross-boarding, and can also realize the simultaneous and even output of the ports of the current card and the target card.
