All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The character "/" herein generally indicates that the associated object is an "or" relationship. For example, A/B may be understood as A or B.
The terms "first" and "second" in the description and in the claims of the application are used for distinguishing between different objects and not for describing a particular sequential order of objects. For example, the first edge service node and the second edge service node are used to distinguish between different edge service nodes, rather than to describe a characteristic order of the edge service nodes.
Furthermore, references to the terms "comprising" and "having" and any variations thereof in the description of the present application are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed but may optionally include other steps or elements not listed or inherent to such process, method, article, or apparatus.
In addition, in the embodiments of the present application, words such as "exemplary", or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary", or "such as" is intended to present concepts in a concrete fashion.
In the edge cloud scheduling scene of the computing network, when a newly established service application session leads to the load overrun of a mobile edge computing (mobile edge computing, MEC) server for the same user, a computing network scheduling system schedules the subsequent newly established session of the service to a new MEC server for processing so as to reduce the load pressure of the original MEC server. Illustratively, corresponding to the foregoing technical ideas, two solutions are provided in the prior art:
In the first scheme, the original session is kept in the MEC server with overrun load for processing through the flow viscosity maintaining technology.
However, under the process of scheme one, the load pressure of the original MEC server may always exist, so that the experience of the user served by the MEC server is poor.
In the second scheme, the critical session that causes the load of the MEC server to be over-limited is rescheduled to the idle MEC server, and the network interconnection protocol (Internet Protocol, IP) quintuple (i.e. source IP, destination IP, source port, destination port, transport layer protocol) of the traffic will be referred to by the rescheduling of the session, while the session IP quintuple of the same user is the same. Therefore, the second scheme cannot distinguish the original session from the newly-built session at present, which causes that other established sessions of the user are rescheduled to another idle MEC server, and the original normal service flow is interrupted.
In order to solve the defects in the prior art, the application provides a power network scheduling method and a power network scheduling device, which can solve the problem that the load pressure of an MEC server always exists when the load of the MEC server exceeds the limit at the present stage, so that the experience of a user served by the MEC server is poor.
Exemplary, as shown in fig. 1, a schematic diagram of an application scenario of a power network scheduling method provided by the present application is shown. In this application scenario, it includes: the system comprises an algorithm network orchestration system 10, a service gateway 11, a forwarding device 12, user terminals 13, a first MEC server 14, a second MEC server 15.
Wherein, the calculation network orchestration system 10 is configured to receive the load overrun information from the first MEC server 14 when the first MEC server 14 determines that the load is overrun. Meanwhile, the network orchestration system 10 is further configured to send, to the service gateway 11, indication information for resetting a critical session according to the load overrun information, where the critical session is a session that causes the load overrun of the first MEC server. Optionally, the indication information sent by the algorithm arrangement system 10 to the service gateway 11 further includes load overrun information.
In one possible implementation, computing network orchestration system 10 is also used to number management of MEC servers in the computing network.
Service gateway 11 is configured to receive indication information sent by computing network orchestration system 10 for resetting the critical session. Then, the service gateway 11 resets the critical session according to the foregoing indication information, determines a first message indicating the forwarding device 12 to forward the critical session, and sends the first message to the forwarding device 12.
Alternatively, the first message may be in the format of a transmission control protocol (Transmission Control Protocol, TCP) message.
And the forwarding device 12 is configured to forward the critical session according to the first packet sent by the service gateway 11 after receiving the first packet. Alternatively, forwarding device 12 may be a routing device or a switching device.
The user terminal 13 sends a power calculation service request to the MEC server, so that the MEC server provides a power calculation service for the user. Specifically, the user terminal 13 is a device with a wireless communication function, which may be deployed on land, including indoor or outdoor, hand-held or vehicle-mounted. Can also be deployed on the water surface (such as a ship, etc.). But may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The user terminal 13, also called User Equipment (UE), mobile Station (MS), mobile Terminal (MT), terminal, etc., is a device that provides voice and/or data connectivity to a user. For example, the user terminal 13 includes a handheld device, an in-vehicle device, and the like having a wireless connection function. Currently, the user terminal 13 may be: a mobile phone), a tablet, a laptop, a palmtop, a mobile internet device (mobile INTERNET DEVICE, MID), a wearable device (e.g., a smart watch, a smart bracelet, a pedometer, etc.), a vehicle-mounted device (e.g., an automobile, a bicycle, an electric car, an airplane, a ship, a train, a high-speed rail, etc.), a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a wireless terminal in an industrial control (industrial control), a smart home device (e.g., a refrigerator, a television, an air conditioner, an electric meter, etc.), a smart robot, a workshop device, a wireless terminal in an unmanned (SELF DRIVING), a wireless terminal in a teleoperation (remote medical surgery), a wireless terminal in a smart grid (SMART GRID), a wireless terminal in a transportation security (transportation safety), a wireless terminal in a smart city (SMART CITY), or a wireless terminal in a smart home (smart home), a flying device (e.g., a smart robot, a hot balloon, an unmanned aerial vehicle, etc. In one possible application scenario of the application, the terminal is a terminal that is often operated on the ground, for example a vehicle-mounted device. In the present application, for convenience of description, a Chip disposed in the above-mentioned device, such as a System-On-a-Chip (SOC), a baseband Chip, etc., or other chips having a communication function may also be referred to as the user terminal 13.
It will be appreciated that in this scenario, the first MEC server 14 is an overrun MEC server after critical session establishment. The second MEC server 15 is an idle MEC server assigned to the user by the computing network orchestration system 10 to continue to provide business services to the user.
It should be noted that, the conditions that need to be satisfied in the application scenario of the present application are: 1) The same business in different MEC servers corresponds to the same service identifier; 2) The session established by the user service is a TCP session; 3) The network is provided with a flow viscosity maintaining technology; 4) The MEC server carries out numbering identification and is uniformly managed by the computing network arrangement system.
The following describes the flow of the power network scheduling method provided in this embodiment.
Illustratively, as shown in fig. 2, the present application provides a power network scheduling method, which includes the following steps:
S201, the calculation network arrangement system receives the load overrun information.
The load overrun information is used for indicating the load overrun of the first MEC server.
Optionally, after the critical session is established and the load of the first MEC server exceeds the limit, the first MEC server reports the load exceeding information to the network planning system.
S202, the computing network arranging system sends first indication information to the service gateway. Correspondingly, the service gateway receives the first indication information.
The first indication information is used for indicating the service gateway to reset the critical session.
The critical session is a session that causes the load of the first MEC server to be overrun.
Optionally, the first indication information includes load overrun information and a number of the second MEC server. The second MEC server is an idle MEC server distributed to the user after the load of the first MEC server exceeds the limit, and is used for providing business service for the user after the load of the first MEC server exceeds the limit.
Optionally, the computing network orchestration system determines the second MEC server after receiving the load overrun information from the first MEC server.
S203, the service gateway resets the critical session according to the first indication information to determine the first message.
The first message is used for indicating the forwarding device to forward the critical session.
Optionally, the format of the first packet is a TCP packet. Illustratively, as shown in fig. 3, fig. 3 shows a header structure of a TCP packet according to an embodiment of the present application. Optionally, in the embodiment of the present application, the forwarding device is instructed to forward the critical session by modifying a reserved field in the TCP packet.
It will be appreciated that the reserved field of the TCP message shown in fig. 3 is 6 bit and binary. Thus, the reserved field may represent up to 32 different numbers. In the embodiment of the present application, each bit of the reserved field is 0, that is, when the reserved field is a special value "000000", it indicates that the load of the first MEC server is not exceeded, and the forwarding device forwards the current session according to the current forwarding table entry. And when each bit in the reserved field is not 0, namely 31 conditions except '000000', the load of the first MEC server is over-limited, the calculation network arrangement system distributes the second MEC server to continue to provide the calculation service for the user, and the numerical value of the reserved field is the number of the second MEC server.
In one possible implementation, the service gateway modifies the reserved field in the TCP packet corresponding to the critical session according to the number of the second MEC server in the first indication information. Illustratively, the computing network orchestration system assigns the number "000010" to the second MEC server, and the service gateway modifies the reserved field in the TCP message to have an initial value of "000000" to "000010".
S204, the service gateway sends a first message to the forwarding equipment. Correspondingly, the forwarding device receives the first message.
S205, forwarding the critical session by the forwarding device.
Optionally, the forwarding device determines the second MEC server according to the number of the second MEC server indicated by the reserved field in the first message.
Further, the forwarding device determines a forwarding table entry according to the number of the second MEC server and the output interface of the forwarding device. It should be noted that, the forwarding table entry is newly generated for the forwarding device, and can query a forwarding path from the forwarding device to the second MEC server. Illustratively, the forwarding device may keep the original forwarding table entry stored such that the subsequent traffic gateway indicates to continue to use the forwarding table entry when forwarding of the session is scheduled to the first MEC server.
Optionally, the forwarding device forwards the critical session according to the forwarding table entry. It will be appreciated that, corresponding to the foregoing description, the forwarding device forwards the critical session according to the forwarding path from the forwarding device to the second MEC server queried in the forwarding table entry.
In addition, it should be noted that, corresponding to the description in S203, when the reserved field in the TCP packet received by the forwarding device from the service gateway is a special value "000000", that is, it indicates that the load of the first MEC server is not exceeded, the forwarding device forwards the current session according to the original forwarding table entry.
Based on the technical scheme, the network computing orchestration system instructs the service gateway to reset the critical session causing the load overrun under the condition that the load of the MEC server exceeds the load, and modifies the reserved field in the TCP message corresponding to the critical session, so as to realize the addition of the identification and recognition functions of the session in the power computing network. The service gateway can then instruct the forwarding device to schedule the critical session to an idle MEC server assigned by the computing network orchestration system. Therefore, when the load of the MEC server is over-limited, the method and the system for scheduling the critical session of the MEC server to the idle MEC server for the same service of the same user, which causes the load to be over-limited, reduce the load pressure of the original MEC server and improve the service experience of the user.
As shown in fig. 4, in an exemplary manner, in connection with fig. 2, the method for scheduling a computing power network provided by the present application further includes the following steps after the forwarding device forwards the critical session:
s401, the service gateway resets a second message corresponding to the target session.
Wherein the target session is a session established after the critical session. And, the reserved field in the second message is a special value, i.e. "000000". The second message is used for indicating the forwarding equipment to forward the target session according to the current forwarding table item.
It will be appreciated that after the forwarding device forwards the critical session to the second MEC server, the subsequent session continues to be scheduled to the second MEC server by the forwarding device according to the forwarding table entry newly generated in S205. Before the load of the second MEC server exceeds the limit, a calculation network arrangement system is not required to reassign a new idle MEC server, so that the service gateway needs to reset a TCP message corresponding to the target session, resets a reserved field in the TCP message to a special value of 000000, indicates forwarding equipment to not need to generate a new forwarding table item, and continues to schedule and forward the target session by using the current forwarding table item.
S402, the service gateway sends a second message to the forwarding equipment. Correspondingly, the forwarding device receives the second message.
S403, the forwarding device forwards the target session according to the second message.
It can be understood that, corresponding to the description in S401, after the forwarding device receives the second packet and identifies the reserved field in the second packet as the special value "000000", it is unnecessary to generate a new forwarding table entry, and forwarding scheduling is performed on the target session according to the forwarding table entry generated by the first packet.
Based on the technical scheme, the embodiment of the application can enable the subsequent session to be continuously scheduled to the idle MEC server after the critical session is scheduled to the idle MEC server distributed by the computing network arrangement system, does not need to update the forwarding table item every time the session arrives at the forwarding equipment, simplifies the flow of session scheduling forwarding, and enables the user experience of the computing service corresponding to the session to be better.
The embodiment of the application can divide the functional modules or functional units of the power network dispatching device according to the method example, for example, each functional module or functional unit can be divided corresponding to each function, and two or more functions can be integrated in one processing module. The integrated modules may be implemented in hardware, or in software functional modules or functional units. The division of the modules or units in the embodiment of the present application is schematic, which is merely a logic function division, and other division manners may be implemented in practice.
Exemplary, as shown in fig. 5, a schematic diagram of a possible architecture of a power network scheduling apparatus according to an embodiment of the present application is shown. The power network scheduling apparatus 500 includes: a receiving unit 501, a processing unit 502, and a transmitting unit 503.
Wherein, the receiving unit 501 is configured to receive first indication information from the computing network orchestration system; the first indication information is used for indicating the service gateway to reset the critical session.
A processing unit 502, configured to reset the critical session according to the first indication information, so as to determine a first packet; the first message is used for indicating the forwarding device to forward a critical session, wherein the critical session is a session for enabling the load of the first mobile edge computing MEC server to be out of limit.
A sending unit 503, configured to send the first packet to the forwarding device.
