Background
Fibre Channel (FC) is a high-speed serial bus with high bandwidth, high reliability and strong anti-interference capability. The FC-AE standard for avionics is being widely used in an increasing number of avionics and military equipment. With the increase of the number of nodes and the expansion of the scale of the optical fiber network, the limited number of access ports provided by a single optical fiber switch in more and more local area network environments has been difficult to meet the demand. At present, a cascade technology is needed to interconnect a plurality of optical fiber switches instead of a single optical fiber switch, so as to provide more access ports for the system. When optical fiber switches are cascaded, how to ensure that the relay link between the switches has sufficient bandwidth becomes a key point of current research. Only if the bandwidth is enough, the ports of the slave switch can have the same bandwidth as the master switch. However, in some cases, the limited bandwidth of a single cascaded port may be difficult to satisfy the bandwidth requirements for two fabric switch data interactions. In the field of optical fiber switches in the internet, two or more cascaded ports of the same type are generally connected in parallel to transmit data at the same time, and this way of connecting multiple cascaded ports in parallel is called port aggregation.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes an embodiment of a port aggregation processing method for a fabric switch according to the present invention in detail. As shown in fig. 1, which is a schematic flow chart of a port convergence processing method for a fabric switch according to an embodiment of the present invention, a specific implementation process includes the following steps:
step 101: and receiving a data frame to be forwarded, and performing data query on a preset hash table based on the frame identifier of the data frame to obtain a corresponding port aggregation group number and a source port number of the data frame.
In the embodiment of the present invention, before executing this step, a port state table and a port number configuration table corresponding to the port aggregation group, that is, a Trunk port state table and a Trunk port number configuration table, need to be configured in advance. Specifically, when the optical fiber switch in the port aggregation group is initialized, the port state table and the port number configuration table corresponding to the port aggregation group may be configured. All initial bit (bit) bits of the port state table and the port number configuration table are 0, when a cascade port is configured in the optical fiber switch in the port convergence group, a corresponding bit in the port state table is set to be 1, and the port number of the cascade port is stored in the port number configuration table. Each table entry contained in the port state table is 8 bits, each bit corresponds to a cascade port, and the cascade port contains the target port; each table entry contained in the port number configuration table has 40 bits and is used for storing the port numbers of all the cascading ports in the port aggregation group. Wherein, each port aggregation group is called a Trunk.
In the specific implementation process, all bits of the port state table and the port number configuration table which are just powered on are 0, when a cascade port (port) corresponding to the port aggregation group is configured, the corresponding bit in the port state table is written into 1, and the corresponding port number is stored in the port number configuration table. Of course, the system may add, delete, or modify the cascade ports in the port aggregation group according to a preset rule according to an actual situation, and update the port state table of the port aggregation group and the value of the corresponding bit in the port number configuration table of the port aggregation group, respectively. For example, in the deleting process, only 0 needs to be written into the corresponding bit in the port state table, and the port number configuration table may adopt a circular covering mode, and then 0 does not need to be written.
As shown in fig. 3 and 4, which are a configured port state table and a port number configuration table, respectively. In the configuration shown, two ports having a port number equal to 8 and a port number equal to 31 are configured as port0 and port7 of Trunk 0. Each table entry in the port state table is 8 bits, and each bit indicates whether the port has configuration (1 has configuration, 0 has no configuration); the port number configures each entry 40bit in the table, and all the port numbers in the port aggregation group are stored.
It should be noted that, in the process of forwarding the data frame, the port state table may also be updated by obtaining a link indicator signal (i.e., link signal) corresponding to the optical fiber switch in the port aggregation group. Specifically, the current link state corresponding to the cascade port of the optical fiber switch in the port aggregation group may be determined based on the level of the link indicator signal; and then updating the value of the bit in the port state table based on the current link state, if the current link state is normal, updating the value of the bit in the port state table to be 1, and if the current link state is abnormal, updating the value of the bit in the port state table to be 0, so as to obtain an updated port state table, which is specifically shown in fig. 5. When the subsequent port convergence group queries the available port number, only the updated port state table needs to be queried, and the position of 1 in the table indicates that the port number corresponding to the position in the port configuration table is available, otherwise, the port is unavailable.
After the port state table and the port number configuration table corresponding to the port aggregation group are configured in advance through the above contents, the step 101 is executed. In this step, a data frame to be routed and forwarded is received first, and a corresponding port aggregation group number is queried through a preset hash table according to a frame identifier in a frame header of the data frame, so that a target port number or a target port (i.e., an available port number or port) in each port aggregation group is queried through a corresponding port query unit in the following. It should be noted that, in the embodiment of the present invention, the number of the port aggregation groups may be determined according to actual needs. Each port aggregation group may be configured with 1-8 ports. When only 1 port is configured in the port aggregation group, the port aggregation group has the same function as a single port of a conventional fabric switch. When the number of the ports configured in the port convergence group is greater than or equal to 2, the normal port convergence function can be realized.
Step 102: determining a corresponding port aggregation group according to the port aggregation group number; based on the port state table and the source port number of the port convergence group, searching whether a corresponding target port number exists in a port number configuration table of the port convergence group in a polling mode, and if so, forwarding the data frame based on a target port corresponding to the target port number; and the port convergence group is pre-configured with cascade ports corresponding to at least two optical fiber switches.
And when a data frame routing request exists, returning the inquired target port number to the application end in a polling mode. And the load balancing can be realized by a port polling mode and is distributed to all the cascaded ports in the configured port aggregation group. In a specific implementation process, when a new application is generated next time, a new port needs to be queried downwards on the basis of the port number recorded last time, that is, when a new data frame to be forwarded is received, a new target port number is queried in a polling manner on the basis of the current target port number, and the new data frame to be forwarded is forwarded on the basis of the new target port number; wherein, the new target port number is different from the cascade port corresponding to the current target port number. If the target port is not queried in the 8 cascaded ports, the query is stopped.
In the specific implementation process, aiming at the requirements of multicast and broadcast, when there is a data frame routing request, all the port aggregation groups firstly judge whether there is a routing request corresponding to the port aggregation group, if so, the query flow is started, otherwise, the query flow is directly returned to 0 (no target port is available). In the case of multicast and broadcast, when a port belonging to a certain port aggregation group initiates a data frame routing request, it is required that the port aggregation group cannot return any valid port number, otherwise a broadcast storm may occur. In order to avoid this, when a route is queried by the route query module, in addition to querying the port aggregation group number according to the frame header information of the data frame, the port number (i.e., the source port number) from which the data frame originates needs to be analyzed from the frame header information, so as to obtain the port aggregation group number and the source port number that are transmitted, first, the source port number is compared with all the port numbers of the port aggregation group, and if a port number equal to the source port number exists in all the ports of the port aggregation group, the port aggregation group cannot return to any port.
During the operation of the optical switch, if the link to which the returned route points is unavailable (for example, a physical failure of the link), traffic blocking of the optical switch may be caused. Therefore, the link state of a port needs to be monitored in real time, and usually, all optical fiber switches have a link indicator mark link signal, that is, a link indicator mark signal (link is high level indicating that a port is available, and a low level port is not available), and in a port query process based on a port aggregation group, if a link corresponding to a certain port is not available, the link is directly skipped over to find a next available port.
Any N (N > =1) ports (namely cascading ports) of the optical fiber switches are configured into a port aggregation group, and port numbers in the port aggregation group are returned in a polling mode according to the current link state, the source port number and the application type, so that high bandwidth is established between at least two optical fiber switches, and load balance is achieved.
In addition, in the process of forwarding a data frame, acquiring a link indicator signal corresponding to the optical fiber switch in the port aggregation group, and determining a current link state corresponding to a cascade port of the optical fiber switch in the port aggregation group based on the level of the link indicator signal; updating the value of a bit in the port state table based on the current link state, if the current link state is normal, updating the value of the bit in the port state table to be 1, and if the current link state is abnormal, updating the value of the bit in the port state table to be 0 to obtain an updated port state table; based on the updated port state table and the source port number, searching whether a port number corresponding to a target port with a normal current link state exists in a port number configuration table of the port convergence group by a preset port query unit in a polling mode; and if so, forwarding the data frame based on the target port with the normal current link state.
In a specific implementation process, after the port state table and the port number configuration table corresponding to the port aggregation group are configured in advance, normal data frame exchange of the optical fiber switch can be performed.
As shown in fig. 2, first, the route query module receives a data frame, and queries a port aggregation group number and a source port number of the data frame through a preset hash table according to a frame identifier in a frame header; then, the queried port aggregation group number and the port number of the source data frame are input to a Trunk module (port aggregation processing module). And the Trunk module queries available port numbers according to a preset flow. For example, for a 32-port switch, in order to adapt to various situations, 32 port query units need to be instantiated, and each port query unit is responsible for querying the port number in a port aggregation group. The actual port number obtained by querying by the 32 port querying unit is the actual routing result. The results queried by the 32 port query units are not always available, and only effective query results are selected. The following describes a preset process by taking an example that the port aggregation group includes seven cascaded ports, which specifically includes: if no port number equal to the source port exists in the port aggregation group; reading a port position addr recorded by a last forwarding data frame; the following judgment processes are carried out in sequence: judging whether the bit =1 of the (addr + 0) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 1) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 2) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 3) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 4) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 5) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 6) th port mapping table of the combined link signal exists, judging whether the bit =1 of the (addr + 7) th port mapping table of the combined link signal exists, and if the bit =1 of the (addr + 7) th port mapping table of the combined link signal exists, finishing the query in the flow, recording the position of the corresponding target port and returning the corresponding port number; if not, finishing the query and determining that no target port is available in the port convergence group. The Trunk port mapping table combining the link signals is a Trunk port number configuration table or a port number configuration table. The internal Trunk table in fig. 2 is a port state table or Trunk port state table corresponding to the port aggregation group.
According to the port convergence processing method for the optical fiber switch, provided by the embodiment of the invention, the corresponding target port forwarding data frame is searched by polling the port convergence group of the cascade port corresponding to at least two optical fiber switches, so that the bandwidth of the cascade port of the optical fiber switch is improved, the adaptability is strong, and the efficiency and the stability of data frame forwarding can be effectively improved.
