Description
Technical Field
The present application relates to the field of network communication technologies, and in particular, to a method and an apparatus for distributing a packet.
Background
With the wide application of new technologies such as cloud computing and high-definition video, the data volume transmitted in the network shows geometric growth. The rapidly increasing data transmission of networks puts higher demands on network bandwidth and network architecture. Previously, in networks, conventional large capacity box devices were generally used for network data transmission. Because the traditional high-capacity box type equipment has the problems of processing performance limit and poor expansibility, the traditional high-capacity box type equipment can not meet the requirement of rapidly increasing network data transmission. Nowadays, in order to meet the requirement of the transmission of network data which is rapidly increased, a frame type network high-performance device (a frame type device for short) is adopted. The frame type device has the advantages of high performance and expandability, and the processing performance of the frame type device can be increased by inserting the board card into the frame type device at any time.
In practical application, a service board card may be inserted into the frame device for processing the service packet. In order to improve the reliability of the frame device in processing the service, the service packet is usually processed by using the main/standby service board card. Under normal conditions, the main service board processes the service message, and the standby service board is in a standby state. When the main service board card fails, the main service board card is switched to the standby service board card, and the standby service board card continues to process the service message, so that normal processing of the service message is ensured.
However, when the main service board is in a working state, the standby service board is always in a standby board, and the standby service board is not fully used, which results in resource waste. In the prior art, a cloud board card technology is provided for fully utilizing each service board card in frame type equipment. The cloud board card refers to aggregating a plurality of service board cards of the same type into one logic board card. When the service message passes through the frame type equipment, the frame type equipment can equally distribute the service message to each service board card, and each service board card averagely shares the processing of the service message. When any one of the service board cards fails, the service messages originally processed by the service board card can be evenly distributed to the rest of the remaining service board cards.
In the prior art, when a frame device allocates a service packet to each service board based on a preset allocation rule, the service packet is generally allocated to each service board by using a packet feature based on the service packet. For example, the service packets are evenly distributed to each service board based on the source IP and the destination IP of the service packets.
In actual operation, messages of the same service need to be processed by the same service board, that is, both forward service messages (service messages sent from the intranet to the extranet) and reverse service messages (service messages sent from the extranet to the intranet) of the same service need to be distributed to the same service board.
The device shown in the prior art performs a flow splitting process on a forward service packet and a reverse service packet based on packet characteristics in the same designated field, however, in some network environments, packet characteristics obtained from the designated field of the forward service packet are different from packet characteristics obtained from the same designated field of the reverse service packet, so that the forward service packet and the reverse service packet of the same session are processed by different service boards.

The device shown in the prior art performs a flow splitting process on a forward service packet and a reverse service packet based on packet characteristics in the same designated field, however, in some network environments, packet characteristics obtained from the designated field of the forward service packet are different from packet characteristics obtained from the same designated field of the reverse service packet, so that the forward service packet and the reverse service packet of the same session are processed by different service boards.
Example one
In order to implement that messages of the same service are processed by the same service board, the present application provides a method for distributing messages, please refer to fig. 2, where fig. 2 is a schematic block diagram illustrating a principle of distributing service messages by a frame network device according to an embodiment of the present application.
In an embodiment of the present application, the frame network device includes a plurality of service boards. And generating an intra-domain cloud board card and an extra-domain cloud board card based on the aggregation of the plurality of service board cards, wherein the position of the same service board card in the intra-domain cloud board card is the same as the position of the same service board card in the intra-domain cloud board card.
The cloud board card in the domain is used for processing a forward service message, the forward service message is a service message sent from an internal network to an external network, the cloud board card outside the domain is used for processing a reverse service message, and the reverse service message is a service message sent from the external network to the internal network.
The cloud board cards in the domain and the cloud board cards outside the domain are both logic board cards, and the cloud board cards in the domain and the cloud board cards outside the domain are generated by aggregation of the same physical board cards in the frame type network equipment.
For example, the frame network device includes 4 service boards, the frame network device aggregates the 4 service boards to generate an intra-domain cloud board, the intra-domain cloud board includes the 4 service boards, and based on the same method, the frame network device also aggregates the 4 service boards to generate an out-of-domain cloud board, and the out-of-domain cloud board also includes the 4 service boards. That is to say, although the out-of-domain cloud board card and the in-domain cloud board card respectively include 4 service board cards, actually, 4 service board cards in the out-of-domain cloud board card and 4 service board cards in the in-domain cloud board card are the same 4 service board cards.
Referring to fig. 3, fig. 3 is a flowchart of a method for distributing a packet according to an embodiment of the present application, which is applied to a frame network device, and specifically executes the following steps:
step 301: when a service message is received, determining a target cloud board card of the service message;
step 302: extracting predetermined message characteristics from the service message; the message characteristics extracted from the forward service message are the same as the message characteristics extracted from the reverse service message of the same service;
step 303: and determining a target service board card for processing the service message in the target cloud board card based on the message characteristics, and distributing the service message to the target service board card.
In this embodiment, when the frame network device receives a service packet, the receiving module may determine whether the service packet is a forward service packet or a reverse service packet. The forward service message is processed by the intra-domain cloud board card, and the reverse service message is processed by the extra-domain cloud board card.
When the service message is a forward service message, the receiving module may determine that a destination cloud board card of the service message is an intra-domain cloud board card; when the service packet is a reverse service packet, the receiving module may determine that a destination cloud board of the service packet is an out-of-domain cloud board.
The cloud board cards in the domain and the cloud board cards outside the domain both include a plurality of service board cards, and after the receiving module determines the target cloud board card of the service message, the receiving module also needs to further determine the target service board card of the target cloud board card for processing the service message.
In this embodiment, the receiving module may extract a predetermined message feature from the service message, and determine, based on the message feature, a destination service board in the destination cloud board for processing the service message.
In order to realize that the service messages of the same service are processed by the same service board card, that is, the forward service message and the reverse service message of the same service can be distributed to the same service board card, and the service board card is distributed to which service board card is determined based on the message characteristics extracted from the service messages, therefore, the message characteristics extracted from the forward service message by the receiving module must be the same as the message characteristics extracted from the reverse service message; the extracted message features may be single message features or a combination of multiple message features.
However, in some network environments, no matter any message feature or combination of multiple message features is used as a basis for determining a destination service board, if the technical solution provided by the prior art is adopted, the destination service board determined by the frame network device based on the message feature extracted from the forward service message will be different from the destination service board determined by the frame network device based on the message feature extracted from the reverse service message.
In this embodiment, since the forward service packet and the reverse service packet are processed by the intra-domain cloud board card and the extra-domain cloud board card respectively, and the intra-domain cloud board card and the extra-domain cloud board card are independent from each other when processing the service packet, a process of extracting a packet feature from the forward service packet and a process of extracting a packet feature from the reverse service packet by the receiving module are also independent from each other.
In an optional implementation manner, when the service packet received by the receiving module is a forward service packet, the receiving module may extract a destination IP address (server IP address) and/or a destination MAC address (server MAC address) from the forward service packet, and then calculate the extracted destination IP address and/or destination MAC address through a preset algorithm, so as to determine a destination service board processing the forward service packet in the intra-domain cloud board, so that the destination service board processes the forward service packet.
When the receiving module receives a reverse service packet of the same service, the receiving module may extract a source IP address (server IP address) and/or a source MAC address (server MAC address) from the reverse service packet, and then calculate the extracted source IP address and/or source MAC address through the same preset algorithm, so as to determine a destination service board for processing the reverse service packet in the out-of-domain cloud board, so that the destination service board processes the reverse service packet.
The destination IP address and/or destination MAC address extracted from the forward service message by the receiving module is the same as the source IP address and/or source MAC address extracted from the reverse service message of the same service by the receiving module, and the algorithm used when calculating the destination service board card is the same, so the forward service message and the reverse service message of the same service can be processed by the same service board card.
The service board card in the frame network device can break down in actual operation, so that a service error is avoided because the broken-down service board card is not removed in time, the state of the service board card needs to be detected by the frame network device, and the broken-down service board card is removed in time.
In this embodiment, the frame network device periodically detects the working state of the service board, and when any service board fails, the frame network device may delete the service board from the intra-domain cloud board and the extra-domain cloud board.
If a service board card is newly added to the frame type network device, the frame type network device may add the service board card to the intra-domain cloud board card and the extra-domain cloud board card, where the position of the service board card in the intra-domain cloud board card is the same as the position of the service board card in the extra-domain cloud board card.
Regardless of the increase or decrease of the number of the service board cards in the frame type network equipment, the frame type network equipment can uniformly distribute the service messages to all the service board cards.
In this embodiment, when the number of the service boards in the frame network device changes, the frame network device may adjust the distribution of the packet. For example, when a certain service board card fails, the frame network device may evenly distribute service packets originally processed by the service board card to other service board cards.
According to the technical scheme, the intra-domain cloud board card and the extra-domain cloud board card are aggregated to generate the intra-domain cloud board card and the extra-domain cloud board card based on the service board card in the frame type network equipment, wherein the intra-domain cloud board card processes the forward service message, and the extra-domain cloud board card processes the reverse service message. The forward service message is a service message sent from the intranet to the extranet, and the reverse service message is a service message sent from the extranet to the intranet, wherein the positions of the service boards in the intra-domain cloud board card are the same as the positions of the service boards in the extra-domain cloud board card. When the frame network device receives a service message, a destination cloud board card of the service message may be determined, a predetermined message feature may be extracted from the service board card, and then a destination service board card for processing the service message in the destination cloud board card may be determined based on the message feature. Wherein, the message characteristics mentioned in the forward service message are the same as the message characteristics extracted from the reverse service message of the same service. Because the service board cards determined by the same message characteristics are the same, the messages of the same service can be processed by the same service board card.
