Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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 system architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the system architecture and the appearance of a new service scenario.
The above method is described in detail with reference to specific examples.
In the process of forwarding a message by a network device (e.g., a switch, a router, or other three-layer network device), the message needs to be encapsulated again before the message is sent from one network device to the next-hop network device, and new link layer header information is encapsulated to the message header. Specifically, before the message is sent out, the link layer header information of the message is re-encapsulated according to the information of the next-hop network device. For example, a message sending port of a network device is an ethernet port, an IP Address of a next hop is 1.1.1.1, and in a message forwarding process, the device obtains the IP Address by querying an Address Resolution Protocol (ARP) table: 1.1.1.1, and packaging or copying the head information of the link layer on the basis of the original IP message according to the Ethernet frame format.
The existing technical schemes for improving the message forwarding performance of network equipment mainly include two types, one is a message batch forwarding technology, namely, a plurality of messages are processed in batch at one time; the other is one-time routing and multiple forwarding, namely, the first message is subjected to complete forwarding information table query, the query result is cached, and the subsequent message directly applies the result. Both of the above two technical solutions cannot avoid performing new link layer header encapsulation on each message to be forwarded before sending the message. Here, it is assumed that the processing performance of the network device is 60MPPS, that is, 60M messages are processed per second, which means that the CPU executes at least 6 million by 2 instructions per second, and the device memory increases at least 6 million by 2 memory accesses per second, which seriously affects the message forwarding performance of the network device.
The embodiment of the invention provides a message forwarding method and a message forwarding device, which are used for improving the message forwarding performance of network equipment (such as a router or a switch and the like) based on three-layer forwarding or similar network equipment based on three-layer forwarding.
An embodiment of the present invention provides a packet forwarding method, as shown in fig. 1, where the method includes:
In this embodiment of the present invention, before obtaining an adjacent entry corresponding to the IP address of the next hop of the packet to be forwarded, the method further includes:
when adding the routing table entry, constructing an adjacent table entry corresponding to the IP address of the next hop for each routing table entry by adopting a Direct Memory Access (DMA) mode;
acquiring link layer header information corresponding to the IP address of the next hop, and storing the link layer header information into a corresponding adjacent table entry; the link layer header information stored in the adjacent table entry at least includes the link layer header and the length of the link layer header.
In this embodiment of the present invention, before obtaining an adjacent entry corresponding to the IP address of the next hop of the packet to be forwarded, the method further includes:
the network equipment receives the message to be forwarded, removes the original link layer header of the message to be forwarded, and acquires the IP address of the next hop corresponding to the message to be forwarded from the routing table, so as to acquire the corresponding adjacent table entry according to the IP address of the next hop.
in this step, the adjacent table entry and the message to be forwarded are respectively stored in the idle buffer descriptor BD, which specifically includes:
storing the adjacent table entry into an idle first BD, setting the sending start address of the first BD as the start address of the link layer head in the adjacent table entry, and setting the sending length of the first BD as the length of the link layer head in the adjacent table entry;
and storing the message to be forwarded into the idle second BD, setting the sending start address of the second BD as the start address of the message to be forwarded, and setting the sending length of the second BD as the length of the message to be forwarded.
As a preferred implementation manner, in the embodiment of the present invention, the BD structure is extended, and a "release" flag is added in each BD to identify an object associated with each BD.
Specifically, in the embodiment of the present invention, the adjacent table entry and the to-be-forwarded message are respectively associated with the idle BD according to the sequence of the adjacent table entry and the to-be-forwarded message. And sets the transmission start address of the BD (i.e., "first BD") in which the adjoining entry is located as the start address of the link layer header in the adjoining entry, and sets the transmission length of the first BD as the length of the link layer header in the adjoining entry. Further, a release identification bit of the first BD is set, and a message end identification bit of the first BD is cleared. The sending start address of the BD (i.e., "second BD") where the message to be forwarded is located is set as the start address of the message to be forwarded (the message does not include the link layer header), and the sending length of the second BD is set as the length of the message to be forwarded (the message does not include the link layer header). Further, the release flag bit of the second BD is cleared, and the message end flag bit of the second BD is set.
And 103, sending the message to be forwarded according to the BD.
In this step, sending the packet to be forwarded according to the BD specifically includes:
according to the sending start address and the sending length in the first BD, sending a link layer header corresponding to the IP address of the next hop of the message to be forwarded;
and sending the message to be forwarded according to the sending start address and the sending length in the second BD.
In the embodiment of the invention, after receiving a message to be forwarded, a network device delivers an adjacent table entry corresponding to the IP address of the next hop of the message to be forwarded and the message to be forwarded to a driver corresponding to a device sending port together, the driver stores the adjacent table entry and the message to be forwarded into an idle BD respectively and informs the device sending port that the two BDs are ready, and after receiving the notification, the device sending port sends the adjacent table entry and the message to be forwarded according to the sequence of the BD where the adjacent table entry is located first and the BD where the message to be forwarded is located later, so that the link layer header encapsulation of the message to be forwarded is not required to be carried out again before sending the message, the link layer header encapsulation of the message to be forwarded is avoided to be carried out again before forwarding the message, the processing time of a CPU is saved, and the memory access pressure is reduced.
In the embodiment of the present invention, whether the transmission is completed or not may be determined by checking the "DMA DONE" flag bit of the BD, and for the BD that has completed the transmission, the "release" flag bit thereof is checked, and if the flag bit is set, it indicates that the BD transmits the adjacent entry, and the adjacent entry is not released. If the identification bit is cleared, the BD sends a message to be forwarded, and the message to be forwarded is released.
Optionally, when each routing table entry in the routing table is deleted, the IP address of the corresponding next hop is obtained from the deleted routing table entry, the corresponding adjacent table entry is obtained from the IP address of the next hop, and the association relationship between the adjacent table entry and the IP address of the next hop is released, so that the adjacent table entry is released.
In the message forwarding method provided by the embodiment of the invention, the network device stores the adjacent table entry corresponding to the next hop IP address of the message to be forwarded and the message to be forwarded into a plurality of BD together, and the automatic replacement of the head part of the message link layer can be completed by utilizing the multi-BD message sending function supported by the sending port of the network device, so that the hardware resource of the sending port is fully utilized, the processing time of a CPU (central processing unit) in the message forwarding process is saved, and the memory access pressure is reduced. Thereby effectively improving the message forwarding performance of the CPU.
For example, by applying the message forwarding method provided by the embodiment of the present invention, for a network device with a message throughput of 60MPPS, the memory access amount can be saved by at least 6 million by 2 times per second. In an actual application scenario, the optimization of the message forwarding performance by the method also depends on the time ratio of the link layer header encapsulation time in the whole message forwarding process. Experimental data show that the message forwarding performance can be improved by 10% to 20%.
