In the above operating environment, the present application provides a method of data processing as shown in fig. 2.

Fig. 2 is a flow chart of a data processing method according to an embodiment of the present invention. As shown in fig. 3, the data processing method may include the steps of:

step S202, current flow data of a first port of a switch in the content distribution network is obtained.

In the technical solution provided in the above step S202 of the present invention, the packet port charging is a charging method that requires paying for the operator regardless of whether the user is used, the 95 port charging is a charging method that charges 95% of the traffic of the bandwidth, the highest 5% of the traffic is not charged, and the 95 charging port and the packet port are two charging logics when the bandwidth is leased, and both of the charging logics form a new bandwidth combination method in the application.

In this embodiment, current traffic data of a first port of a switch in a content delivery network is obtained, for example, packet port traffic of a switch in a Content Delivery Network (CDN) is obtained.

In this embodiment, the current traffic data of the first port may be packet port traffic, and when the switch traffic rises or falls, a policy may be further formulated by acquiring the packet port traffic.

In this embodiment, optionally, predetermined traffic data of the switch is obtained, for example, the log (analysis) module counts traffic of 2 egress types of the switch, where the 2 egress types may be a packet port type and a 95 charging port type, and then determines a target traffic threshold based on the predetermined data, for example, the policy center module performs policy making on a corresponding threshold according to the uploaded switch traffic details, where the log (analysis) module may obtain traffic details of each advanced member (Very Important Person, abbreviated as VIP) for subsequent policy production, and may also obtain traffic details of the packet port type and the 95 charging port type of the switch for subsequent policy production.

Step S204, based on the current flow data and the target flow threshold, determining the scheduling flow data needing to be scheduled.

In the technical solution provided by step S204 of the present invention, the target traffic threshold may be a value determined according to the total traffic of the packet ports.

In this embodiment, scheduling traffic data that needs to be scheduled may be determined based on the current traffic data and the target traffic threshold, for example, when the total traffic of packet ports exceeds the set threshold, the policy center calculates the traffic that needs to be scheduled to the 95 charging port; and when the total flow of the packet ports is smaller than a set threshold value, the strategy center calculates the flow needing to be adjusted to the packet ports.

In this embodiment, it may be determined that first scheduled traffic data needs to be scheduled to a second port in response to the current traffic data exceeding a target traffic threshold, where the second port may be a 95 charging port, and the first scheduled traffic data may be 95 charging port traffic that needs to be scheduled, or it may be determined that second scheduled traffic data needs to be scheduled to a first port in response to the current traffic data not exceeding the target traffic threshold, where the first port may be a packet port, and the second scheduled traffic data may be packet port traffic that needs to be scheduled.

Step S206, forwarding the scheduled traffic data to the switch, where the scheduled traffic data is used to enable the second port or the first port of the switch to obtain the scheduled traffic data, so as to adjust the current traffic data of the first port.

In the technical solution provided in step S206 of the present invention, the scheduling traffic data may be forwarded to the switch, for example, when the packet port traffic exceeds the threshold, the traffic to be transferred to the 95 th charging port is calculated, the policy center calculates a new policy to be transferred to the 95 th charging according to the VIP traffic and the original policy, and transfers the policy to the execution module, the execution module issues the policy to all servers, and the servers forward the data packet to the switch to adjust the current traffic data of the packet port.

In this embodiment, the scheduled traffic data may be used to enable the second port or the first port of the switch to obtain the scheduled traffic data, so as to adjust the current traffic data of the first port, for example, when the current traffic data of the first port (packet port) of the switch exceeds a target traffic threshold, the scheduled traffic data that needs to be scheduled to the second port (95 charging port) is calculated, and after the switch receives a data packet corresponding to the scheduled traffic data, the second port (95 charging port) calls the scheduled traffic data from the first port (packet port), so as to decrease the current traffic data of the first port.

Through the above steps S202 to S206 of the present application, current traffic data of a first port of an exchange in a content distribution network is acquired; determining scheduling traffic data to be scheduled based on the current traffic data and a target traffic threshold; the method includes the steps of forwarding scheduled traffic data to a switch, wherein the scheduled traffic data is used for enabling a second port or a first port of the switch to acquire the scheduled traffic data so as to adjust current traffic data of the first port, that is, in the application, a new traffic forwarding mode is defined, the scheduled traffic data to be scheduled is determined based on the current traffic data and a target traffic threshold, and then the scheduled traffic data is forwarded to the switch so as to adjust the current traffic data, so that traffic scheduling is smoother, efficiency of traffic scheduling is improved, the technical problem of low efficiency of traffic scheduling is solved, and the technical effect of improving efficiency of traffic scheduling is achieved.

The above method of this embodiment is further described below.

As an optional implementation manner, in step S202, current traffic data of a first port of a switch in the content distribution network is obtained, and the method further includes: acquiring preset flow data of a switch; a target flow threshold is determined based on the predetermined flow data.

In this embodiment, predetermined traffic data of the switch is obtained, for example, the logging (analyzing) module counts the traffic sizes of 2 egress types of the switch, where the 2 egress types may be a packet port type and a 95 charging egress type.

In this embodiment, the target traffic threshold is determined based on the predetermined traffic data, for example, after the logging (analysis) module uploads the data to the policy center, the policy center module performs policy making on the corresponding threshold according to the uploaded switch traffic details.

As an optional implementation, obtaining the predetermined traffic data of the switch includes: acquiring first type preset flow data corresponding to a first port of a switch; acquiring second type preset flow data corresponding to a second port of the switch; determining a target flow threshold based on the predetermined flow data, including: a target flow threshold is determined based on the first type of predetermined flow data and the second type of predetermined flow data.

In this embodiment, the first type of predetermined traffic data may be packet port type traffic data and the second type of predetermined traffic data may be 95 billable port type traffic data.

In this embodiment, the target traffic threshold may be determined based on the first type of predetermined traffic data and the second type of predetermined traffic data, for example, after the logging (analysis) module uploads the data to the policy center, the policy center performs policy making according to the uploaded switch traffic details to determine the target traffic threshold.

As an optional implementation manner, in step S204, scheduled traffic data to be scheduled is determined based on the current traffic data and the target traffic threshold, and the method includes: in response to the current traffic data exceeding the target traffic threshold, first scheduled traffic data that needs to be scheduled to the second port is determined.

In this embodiment, the first scheduled traffic data that needs to be scheduled to the second port may be determined in response to the current traffic data exceeding the target traffic threshold, for example, when packet port traffic exceeding the threshold is detected, a signal indicating this information may be generated, and in response to this signal, the traffic that needs to be scheduled to the 95 th billed port may be calculated.

For example, when it is detected that the current traffic data of the first port (packet port) of the switch exceeds the target traffic threshold, the scheduling traffic data that needs to fall to the second port (95 charging port) is calculated, and after the switch receives the data packet corresponding to the scheduling traffic data, the second port (95 charging port) calls the scheduling traffic data from the first port (packet port), so that the current traffic data of the first port is reduced, and the purpose that the current traffic data of the first port (packet port) of the switch falls below the target traffic threshold is achieved, so that traffic scheduling is smoother, the efficiency of scheduling traffic is improved, and the technical effect of improving the efficiency of scheduling traffic is achieved.

As an optional implementation manner, in step S206, the dispatch traffic data is forwarded to the switch, and the method includes: and forwarding the first data packet to the second port through the server, wherein the first data packet is obtained by adding a first identifier to the first scheduling traffic data.

In this embodiment, the first data packet may be forwarded to the second port through the server, for example, when the packet port traffic exceeds a threshold, the traffic of the packet port that needs to be adjusted to 95 charging is calculated, the policy center calculates a new policy that needs to be adjusted to 95 charging according to the member (VIP for short) traffic and the original policy, and transfers the policy to the execution module, assuming that the VIP that needs to be adjusted is VIP-a1, the execution module issues the policy to all servers, the servers mark exit tags 1 on the data packets whose source IP is VIP-a1, and forward the data packets to the 95 charging port, and the exit tags 1 are used to indicate that the data packets are forwarded to the 95 charging port.

In this embodiment, the second identifier is used to indicate an egress tag 1 for forwarding the data packet to a 95 charging port, where the egress tag may be represented by 0, and is intended to distinguish a forwarding policy of the data packet by the server, and the representation form is not limited herein.

As an alternative embodiment, the first identifier of the first packet is recognized by the switch, and the first packet is forwarded to the second port by the switch, so as to reduce the current traffic data of the first port.

In this embodiment, a field of an egress label is added to a packet leaving the server, the switch recognizes this field and forwards the packet according to a predetermined rule, and 2 policy models are configured under the switch to perform matching forwarding on the label of the packet (the field of the egress label).

In this embodiment, the switch receives the corresponding data packet, performs hash calculation, and sends the calculated data packet to a certain 95 charging port, so that the port flow of the switch packet is reduced below the threshold.

As an alternative implementation, in step S204, scheduled traffic data to be scheduled is determined based on the current traffic data and a target traffic threshold, and the method includes: in response to the current traffic data not exceeding the target traffic threshold, second scheduled traffic data that needs to be scheduled to the first port is determined.

In this embodiment, in response to the current traffic datｃA not exceeding the target traffic threshold, second scheduled traffic datｃA that needs to be scheduled to the first port is determined, for example, when packet port traffic is detected to have been less than the threshold, ｃA signal representing this information is generated, and in response to this signal, the policy center selects an appropriate VIP according to the record, modifies the forwarding policy of the VIP to the packet-away port charging, assuming that the VIP that needs to be adjusted is VIP- ｃA.

As an optional implementation manner, in step S206, the dispatch traffic data is forwarded to the switch, and the method includes: and forwarding a second data packet to the first port through the server, wherein the second data packet is obtained by adding a second identifier to the second scheduling traffic data.

In this embodiment, the second datｃA packet may be forwarded to the first port through the server, for example, when the flow of the packet port is smaller than the threshold, the policy center selects an appropriate VIP according to the record, modifies the forwarding policy of the VIP to charging the packet-passing port, assumes that the VIP to be adjusted is VIP- ｃA, the execution module issues the policy to all servers, and the server forwarding module posts an exit tag 0 on the datｃA packet whose source IP is VIP- ｃA according to the policy, and forwards the datｃA packet to the packet port, where the exit tag 0 is used to indicate that the datｃA packet is forwarded to the packet port.

In this embodiment, the second identifier is used to indicate an egress tag 0 for forwarding the data packet to the packet port, where the egress tag may be represented by 0, and is intended to distinguish a forwarding policy of the data packet by the server, and the representation form is not limited herein.

As an alternative, the second identifier of the second packet is recognized by the switch, and the second packet is forwarded to the first port by the switch, so as to increase the current traffic data of the first port.

In this embodiment, a field of an egress label is added to a packet leaving the server, and the switch recognizes this field, and sends the packet to a packet port after receiving a corresponding packet through hash calculation, so that the flow rate of the packet port of the switch increases.

As an optional implementation, the method further comprises: and determining the corresponding virtual resource based on the adjusted current flow data.

In this embodiment, the virtual resource may be a fee that needs to be delivered to the operator.

In this embodiment, the corresponding virtual resource is determined based on the adjusted current traffic data, for example, the CDN must rent the bandwidth of the operator when providing the service to the outside, and the cost to be delivered to the operator may be determined based on the adjusted current traffic.

In the embodiment of the disclosure, the predetermined flow data of the switch is obtained; determining a target flow threshold based on the predetermined flow data; determining first scheduling traffic data needing to be scheduled to a second port in response to the current traffic data exceeding a target traffic threshold; determining second scheduling traffic data needing to be scheduled to the first port in response to the current traffic data not exceeding the target traffic threshold; the corresponding virtual resource is determined based on the adjusted current flow data, that is, the scheduling flow data to be scheduled is determined based on the current flow data and the target flow threshold value, and then the scheduling flow data is forwarded to the switch to adjust the current flow data, so that the flow scheduling is smoother, the efficiency of scheduling flow is improved, the technical problem of low efficiency of scheduling flow is solved, and the technical effect of improving the efficiency of scheduling flow is achieved.

The embodiment of the invention also provides a data processing method from the server side.

Fig. 3 is a flowchart of a data processing method provided from the server side according to an embodiment of the present invention. As shown in fig. 4, the method may include the steps of:

step S302, obtaining scheduling traffic data needing to be scheduled, wherein the scheduling traffic data is obtained by current traffic data of a first port of a switch in a content distribution network and a target traffic threshold.

In the technical solution provided in step S302 of the present invention, the server may obtain scheduling traffic data that needs to be scheduled, for example, the server obtains the scheduling traffic data that needs to be forwarded to the 95 charging port or the packet port according to the current traffic data of the packet port of the switch in the CDN and the target traffic threshold.

Step S304, the scheduled traffic data is forwarded to the switch, where the scheduled traffic data is used to enable the second port or the first port of the switch to obtain the scheduled traffic data, so as to adjust the current traffic data of the first port.

In the technical solution provided in step S304 of the present invention, the server may forward the scheduled traffic data to the switch, for example, after the server obtains the scheduled traffic data that needs to be forwarded to the 95 charging port or the packet port according to the current traffic data of the packet port of the switch in the CDN and the target traffic threshold, the server marks an exit label on the data packet and forwards the data packet to the switch, so as to adjust the current traffic data of the packet port.

Through the steps S302 to S304 described above, scheduling traffic data to be scheduled is obtained, where the scheduling traffic data is obtained from current traffic data of a first port of an exchange in a content distribution network and a target traffic threshold; and forwarding the scheduled traffic data to the switch, wherein the scheduled traffic data is used for enabling a second port or a first port of the switch to acquire the scheduled traffic data so as to adjust the current traffic data of the first port, that is, the scheduled traffic data to be scheduled is determined based on the current traffic data and a target traffic threshold, and then the scheduled traffic data is forwarded to the switch so as to adjust the current traffic data, so that traffic scheduling is smoother, the efficiency of traffic scheduling is improved, the technical problem of low efficiency of traffic scheduling is solved, and the technical effect of improving the efficiency of traffic scheduling is achieved.

Preferred embodiments of the above-described method of this embodiment are further described below.

Fig. 4 is a schematic diagram of a CDN providing a service to the outside according to an embodiment of the present disclosure. As shown in fig. 4, the CDN must lease the bandwidth of the operator when providing a service to the outside, and there are various charging logics, mainly 95 charging and packet port charging, when leasing the bandwidth. The overall bandwidth use cost of the CDN can be reduced by using the flow of the packet port as much as possible, but the DNS scheduling cannot be used for carrying out particularly accurate flow scheduling, the flow scheduled to the corresponding node is small, the flow of the packet port cannot run away, and the bandwidth is wasted; the flow scheduled to the corresponding node is large, and then the packet port flow can be overflowed when a short-time flow burst occurs, so that the service quality is influenced.

Fig. 5 is a schematic diagram of CDN services for a single packet port node according to an embodiment of the present disclosure. As shown in fig. 5, in the charging mode of only packet ports under a node, there may be a problem that the processing quality is affected by insufficient traffic or too high traffic.

Fig. 6 is an architecture diagram of an egress scheduling manner for optimizing CDN charging according to an embodiment of the present disclosure. As shown in fig. 6, the log analysis module may function as: obtaining the traffic details of each VIP through the log analysis module 605 for subsequent policy production; and obtaining the flow details of the 2 charging type ports of the switch 601 through log analysis for subsequent policy production.

The packet format may be expressed as follows:

a source address (MAC) destination address (MAC) egress labels a source IP destination IP Payload (Payload).

The normal IPV4 data format may be expressed as follows:

the source MAC destination MAC exports a label source IP destination IP Payload.

In this architecture, packets leaving the server 602 will be added with a field for the egress label, which the switch 601 will recognize and then forward according to established rules.

The switch policy can be to configure 2 policy models under the switch, and match and forward the label (field of the egress label) of the packet. For example, exit tag 0: transferring the data packet to a packet port; exit label 1: the packet is forwarded to 95 for billing.

The flow is illustrated as follows:

when the switch 601 traffic rises:

1) the logging (analysis) module 605 counts the traffic volume per VIP per minute; counting the flow of 2 outlet types of the switch;
