Detailed Description
The present disclosure is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Referring to fig. 1, which illustrates the principle of an existing FC routing implementation method, an existing FC routing uses a switching fabric, and performs routing processing in units of single interfaces (Bank 0, bank 1..bankn). Accessing the exchange module by using the internal ports of each Bank (for example, the number of the internal ports of each Bank is 1, 2, 4 or 8, etc.); the exchange module preferentially performs sequence arrangement of the Bank (the arrangement sequence polls with effective signals) so as to determine the sequence of the Bank entering the FC routing module; the internal port of the single Bank enters the FC routing module and is subjected to polling sequence processing by taking the effective signal as the reference; the route results are all route results output of a single internal port and are returned to the switching module. And after the results of the port routing processing, such as the Bank number, the address, the routing destination port and the like, are processed by the switching module, the data is distributed to the destination port (namely the output port).
However, this method is to perform routing processing in units of single banks, because each Bank needs to sequentially send routing information of each internal port to the FC routing module, and actually, sequential routing processing is performed in units of single internal ports. The routing information of each Bank needs to be pre-cached in advance, the internal ports of a single Bank share a routing ram table, the occupied routing ram tables are separated and independent by taking the Bank as a unit, ram resources are greatly wasted, and port caching operation is carried out by each Bank, so that the occupation of cache resources is increased. Meanwhile, the FC routing mode can only perform routing processing aiming at the FC protocol, and can not perform protocol conversion in a multi-protocol network environment.
With continued reference to fig. 2, there is shown a timing diagram of one embodiment of an FC route implementation method according to the present disclosure, the FC route implementation method comprising the steps of:
in step 201, each interface polls and acquires the internal port with the highest priority in at least one corresponding internal port, and the internal port is used as the target internal port of each interface.
The interface is also called a Bank. The entire switching device may have multiple interfaces, wherein the interfaces may be generic hardware interfaces. Each interface may carry any one of a plurality of protocols (such as FC protocol, ethernet protocol, etc.), and specifically, one of the protocols is configured by a user to be selected as the protocol carried by the current interface. Thus, a multi-protocol network environment can be formed on the original structure.
Since each interface may include at least one internal port (also referred to as a port), each interface may first poll for the highest priority internal port as the target internal port before entering the switching module.
Step 202, each interface uses the routing information of the corresponding target internal port as the routing information of each interface.
And each interface takes the routing information of the corresponding target internal port as the routing information of each interface respectively. Therefore, for a single interface, each interface only allows the input of one internal port data signal at the same time, and the information entering the switching module can be changed from the routing information of a plurality of internal ports to the determined routing information of a single internal port, so that the data quantity of the internal port cached in the switching module is reduced, and the cache resource occupation can be saved to a certain extent.
In step 203, the switching module receives the routing information sent by the input interface and the protocol types sent by the multiple interfaces.
The input interface may be any interface in the entire switching network that requires FC routing. Each input interface can send the route information of the corresponding target internal port to the exchange module as the route information of the input interface. The routing information of the input interface may be one or more, as the case may be.
Since any interface in the entire FC network may become an output interface (i.e., an interface that receives the routing result of an input interface), multiple interfaces are all interfaces in the entire switching network, and whether or not they are input interfaces, it is necessary to send their protocol types from the switching module. The protocol types carried by all interfaces are obtained in the step, so that the protocol conversion parameters corresponding to the protocol types carried by the output interfaces can be conveniently called in the subsequent step, and the routing result is subjected to format conversion, so that the effect of adapting to the multi-protocol network environment is achieved.
In step 204, the switching module sends the routing information sent by the input interface and the protocol types sent by the multiple interfaces to the FC routing module.
Because the FC routing module can only route the routing information with the protocol type FC protocol type, before sending the routing information to the FC routing module, the routing information with the protocol type FC protocol type needs to be filtered out, and the rest of the routing information will not be processed.
When the input interface is one, if the protocol type of the input interface is FC protocol type, the route information of the input interface and the protocol types of all interfaces can be directly sent to the FC route without format conversion.
When the input interface is plural, step 204 may include the sub-steps of:
in the sub-step 2041, the exchange module obtains an interface with a protocol type being an FC protocol type from the plurality of interfaces, and obtains at least one polling interface.
Because the FC routing module can only route the FC protocol type, it is necessary to screen out the interface with the FC protocol type from the multiple input interfaces (the screened interface is referred to as a polling interface), and then uniformly poll the screened interfaces, so that the multiple interfaces are arranged in a single interface to be input into the FC routing module for routing.
In a sub-step 2042, the switching module polls for priority of at least one polling interface.
Since each interface has been polled before being input to the switching module, it includes only one internal port, the target internal port. Thus, the port priority of the at least one polling interface is polled, i.e., the port priority of the at least one target internal port is polled.
Sub-step 2043, the switching module sequentially sends routing information sent by the at least one polling interface to the FC routing module according to the priority of the at least one polling interface.
And entering the at least one polling interface into the FC route according to the port priority of the at least one polling interface obtained by the polling according to the time stamp arranged sequence. Therefore, each interface does not carry out routing processing in an independent unit, all ports can share the routing table, repeated ram occupation of the routing table is reduced, a port polling mechanism in the interface is simplified, occupation of cache resources is reduced to a certain extent, and the structure has obvious advantages in terms of resource utilization especially under the condition that the number of ports is increased.
Sub-step 2044, the switching module sends the protocol types sent by the plurality of interfaces to the FC routing module.
In step 205, the fc routing module looks up the route according to the routing information sent by the input interface, and obtains the routing result.
Referring to fig. 3, a schematic diagram of FC routing module execution according to one embodiment of the FC routing implementation method of the present disclosure is shown. The process of performing table lookup routing according to the routing information of the single port is the basic behavior of the existing FC routing module. The result output by the whole FC route module comprises a route result, wherein the route result comprises route destination port information (namely output interface information corresponding to an input interface).
Specifically, the process of the FC routing module lookup routing in step 205 includes the following sub-steps:
sub-step 2051: and the FC routing module acquires the indication information of the corresponding output interface from the routing table according to the routing information sent by the input interface.
Sub-step 2052: and the FC routing module routes the routing information sent by the input interface to obtain the routing parameters.
The routing parameters include various parameters generated by the normal route, without limitation.
Sub-step 2053: and the FC routing module generates a routing result according to the indication information of the output interface and the routing parameters.
As a possible implementation, the number of beats used in the process of sub-step 2051 (FC routing module obtains the indication information of the corresponding output interface in the routing table according to the routing information sent by the input interface) is higher than the number of clock beats used in the process of sub-step 2044 (switching module sends the protocol types sent by the interfaces to FC routing module).
With continued reference to fig. 3, compared with the prior art, the present embodiment adds a new protocol type collection process. The process of table lookup routing and protocol type collection processing can be performed in two ways simultaneously, and because the table lookup process is a pipeline process, parameters collected by the protocol type are synchronized with the table lookup result when the table lookup result is completed, so as to improve the routing efficiency, the clock beat number used in step 2051 should be higher than that of step 2044.
In step 206, the fc routing module obtains the protocol conversion parameters according to the protocol type of the input interface and the protocol type of the output interface.
The FC route collects the protocol type of the input interface and the protocol type of the output interface according to the received multiple port protocol types.
When the protocol type of the input interface is inconsistent with the protocol type of the output interface, collecting parameters required for converting the protocol type of the input interface into the protocol type of the output interface, namely protocol conversion parameters, wherein the protocol conversion parameters can be analyzed into analysis results required to be converted. The protocol conversion parameter may be a preset parameter, or may be obtained by analyzing a protocol type of the input interface and a protocol type of the output interface, which is not limited herein.
When the protocol type of the input interface is consistent with the protocol type of the output interface, format conversion is not needed, and therefore, the collection protocol conversion parameter is null. The protocol conversion parameters can be analyzed as no conversion is needed, no format conversion is needed, and only the routing result is directly sent to the output interface.
In step 207, the fc routing module sends the protocol conversion parameters and the routing result to the switching module.
And transmitting the protocol conversion parameters and the routing result to the exchange module, so that the exchange module can perform format conversion on the routing result to generate an information format adapting to the output interface protocol type.
In step 208, the switching module converts the routing result into a format compatible with the protocol type of the output interface according to the protocol conversion parameter, and sends the format to the output interface.
The above step 208 may include the sub-steps of:
sub-step 2081: the exchange module analyzes the protocol conversion parameters to obtain an analysis result.
Substep 2082: and in response to the analysis result being that conversion is required, the switching module converts the routing result into a format compatible with the protocol type of the output interface according to the protocol conversion parameter and sends the routing result to the output interface.
Sub-step 2083: and the switching module sends the routing result to the output interface in response to the analysis result that conversion is not needed.
In summary, referring to fig. 4, which illustrates an FC routing principle according to an embodiment of the FC routing implementation method of the present disclosure, each interface in the method provided in the foregoing embodiment may carry multiple protocols, and by collecting protocol types, an adapted protocol conversion parameter is obtained, so that an FC routing result may be converted into a routing result adapted to multiple protocols, thereby meeting the requirement that multiple protocols coexist and each protocol can be converted mutually in a multiprotocol network environment. And secondly, the interfaces respectively poll a single internal port before entering the switching module, and then the switching module polls the single port from the whole interfaces, so that the whole interfaces share one routing table, the occupation of repeated ram is reduced, and meanwhile, the occupation of cache resources is reduced. In the case of an increased number of ports, the advantage of this structure in terms of resource utilization is significantly increased.
