Description
Technical Field
The present invention relates to the field of internet technologies, and in particular, to a method and an apparatus for introducing an action cycle in network configuration.
Background
The PCEP (Path computing Element Communication Protocol) is a southbound control Protocol that centrally optimizes and computes a network Path and a forwarding policy based on network topology and constraint conditions and advertises the network Path and the forwarding policy to a forwarding node for forwarding according to the optimized Path or policy. In the communication process of the PCEP protocol, a PCE (Path Computation Element) optimizes a Computation network Path and a forwarding policy according to a network topology and constraint conditions (such as bandwidth, LSP (Label switched Path) tunnel, etc.). The PCC (Path Computation Client) requests a Path and a policy from the PCE and forwards the Path and policy. The PCReq (Path Computation Request) in PCEP is a Request Path Computation, and the Pcrep (Path Computation Reply) in PCEP is a PCReq message sent in response to the PCC, and the Reply is a routing Path satisfying the Request or routing failure information.
At present, a plurality of network actions exist on the network, and some network actions are triggered in certain specific time and need to be executed; some network actions need to be executed periodically, for example, DSCP (Differentiated Services Code Point) of video traffic needs to be set to high priority every night at 7: 00-10: 00, so as to ensure the viewing experience of users; the number 15/month 2: 00-6: 00 needs to reserve extra bandwidth for backup traffic; important holidays every year require major safeguards for certain special websites or traffic, etc.
Currently, in the PCEP protocol, network actions that need to be periodically executed need to be manually configured, for example, once a day and once every 5 seconds, the network actions need to be manually configured once a day. This arrangement is relatively inefficient and prone to errors.
In summary, in the existing protocol of PCEP, the network actions that need to be periodically executed all need to be configured manually, so that the configuration efficiency is low and errors are easy to occur.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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.
As shown in fig. 1A, the system for performing network configuration according to the embodiment of the present invention includes: a first network element 10 and a second network element 20.
A first network element 10, configured to determine PCEP configuration information, where the PCEP configuration information includes configuration information of periodic network action execution; and sending the PCEP configuration information to a corresponding second network element so that the second network element executes corresponding actions in corresponding periods according to the configuration information executed by the periodic network actions.
A second network element 20, configured to receive PCEP configuration information from the first network element, where the PCEP configuration information includes configuration information of periodic network action execution; and executing corresponding action in a corresponding period according to the configuration information executed by the periodic network action.
In the embodiment of the present invention, a first network element sends PCEP configuration information including configuration information of a periodic network action execution to a corresponding second network element, so that the second network element 20 executes a corresponding action in a corresponding period according to the configuration information of the periodic network action execution. As the PCEP is expanded, the configuration information of the periodic network action execution is added into the PCEP configuration information, and the manual configuration is not needed for the periodic network action execution, thereby reducing the error rate and improving the efficiency.
The embodiment of the invention expands the PCEP configuration information, and adds the configuration information of the periodic network action execution in the PCEP configuration information.
Optionally, the configuration information of the periodic network action execution includes, but is not limited to, at least one of the following:
a frequency at which the periodic network action is performed;
a start execution time of the network action within each period;
a duration of the network action within each period;
and the message type is used for representing the message type carrying the configuration information of the periodical network action execution.
The frequency of the periodic network action execution refers to the period of the action execution, and includes but is not limited to:
every minute, hour, day, week, month, year, etc.
The starting execution time of the network action in each cycle refers to at which time of each cycle the corresponding action is started to be executed.
The duration of the network action in each period refers to how long the corresponding action lasts in each period.
The message type used for representing the configuration information carrying the periodic network action execution is used for judging the type of the message.
In the implementation process, there are 15 message object type formats in the current PCEP, and the embodiment of the present invention may extend the message object type formats in the PCEP, and add a new type, for example, referred to as a periodic object, to carry configuration information indicating the execution of the periodic network action. The message type used for indicating the configuration information carrying the periodic network action execution is the type used for judging the message, namely the information indicating that the message format is a periodic object.
The following description will take the following example that the configuration information executed by the periodic network action includes the starting execution time of the network action in each period, the duration of the network action in each period, and the message type used for representing the configuration information carrying the periodic network action execution.
1. And the message type is used for representing the message type carrying the configuration information of the periodical network action execution.
Optionally, the message type for indicating to carry the configuration information of the periodic network action execution may occupy a bit of a Common object header in the periodic object, for example, an object-class in the Common object header may be used as the message type for indicating to carry the configuration information of the periodic network action execution.
The specific values may be specified in the protocol. Since 15 types of format in the current PCEP occupy 1-15, the value used for representing the type of the message carrying the configuration information of the periodic network action execution needs to be different from the existing one, and any value larger than 15 and smaller than 255, for example, 16, may be used.
In Common object header, there is also an OT bit as a reserved bit, whose value can be set arbitrarily. Optionally, since the default of the bit is 1 in the current protocol, the default may be set to 1 as well, as shown in fig. 1B.
Accordingly, for the second network element, after receiving the PCEP message, it can determine which format the PCEP message is in according to the specific value of object-class in the Common object header. For example, the specific value of object-class is 16, it can be known that the PCEP message carries configuration information for periodic network action execution.
2. For representing the starting execution time of the network action in each period.
Defining a first group a of object bodies1A bit (e.g. a)1Is 32), for example, starting from the lowest bit, 6 bits are defined Y, M, W, D, H, MI, and the high bits are reserved to indicate the motion cycle requirements of each year, each week, each day, each hour, each minute, etc., as shown in fig. 1C.
Optionally, the first group a of Optional TLVs (Type, Length, Value, Optional Type, Length, and Value) in the periodic object may be occupied for representing the starting execution time of the network action in each period2A bit (e.g. a)2Is 32) to represent the starting execution time of the network action in each period, for example, the frequency of the periodic network action execution is day; the starting execution time of the network action in each period is calculated from 0 o 'clock 0 min 0 s per day to 68400 s at 7 o' clock per day.
Accordingly, for the second network element, after receiving the PCEP message, according to the specific value of Reserved in the periodic object, the start execution time of the network action in each period may be determined, for example:
when the Y position of the periodic action list atom is set, the network action is executed after the time of a few seconds from zero-point zero-minute zero second of 1 month and 1 day of each year;
when the M position of the period action list atom is set, the network action is executed after a few seconds from zero-point, zero-minute and zero-second of 1 day of each month;
when the W position of the period action list atom is set, the network action is executed after a few seconds from zero-point zero-minute zero-second of every day;
when the D position of the period action list atom is set, the network action is executed after a few seconds from zero-point zero-minute zero second every day;
when the H position of the period action list atom is set, the network action is executed after a few seconds from zero minute and zero second every time;
when the MI position of the periodic action list atom is set, the network action is executed from how many seconds per minute after zero seconds.
3. For indicating the duration of the network action within each period.
Optionally, a for indicating that the duration of the network action in each period may occupy the second group of Optional TLVs in the periodic object3A bit (e.g. a)3Is 32).
Accordingly, for the second network element, after receiving the PCEP message, the duration of the network action in each period can be determined according to the specific value in the Optional TLVs in the periodic object, as shown in fig. 1C.
A detailed example is listed below. In this example, the unit is second, and in the implementation, other time units can be used according to specific needs.
If an action is required to be 7 to 10 pm every day, the frequency of the periodic network action is day; the starting execution time of the network action in each period is calculated from 0 o 'clock 0 min 0 s every day to 68400 s at 7 o' clock every night, and the behavior duration is 10800 s after 3 hours. The representation in the periodic object is shown in fig. 1D, in which the configuration of the start execution time and the execution duration of the periodic network action should be in a binary manner, but this example converts it into a decimal expression for understanding.
The period information of the network may also be flexibly defined as required, for example, the Reserved bits in Reserved in the periodic object may be used to perform corresponding definition. Position 20, position 1, and position 28, position 1 in fig. 1D, indicate that the network action is only performed on weekends.
In the implementation process, there are many types of PCEP configuration information, and there are also many ways to extend the type format in the PCEP, and when configuring the periodic network action, this example only extends the PCReq in the PCEP and the PCRep in the PCEP to carry the information of the network action.
When expanding the PCReq, a periodic object needs to be added to the original < Request > list, and the specific format is as follows:
<request>::＝<RP>
<END-POINTS>
[<LSPA>]
[<BANDWIDTH>]
[<metric-list>]
[<RRO>[<BANDWIDTH>]]
[<IRO>]
[<LOAD-BALANCING>]
[<Periodical>]
when expanding the PCRep, a periodic object needs to be added to the original Attribute list, and the specific format is as follows:
<attribute-list>::＝<LSPA>
[<BANDWIDTH>]
[<metric-list>]
[<IRO>]
[<Periodical>]
the scheme of the embodiment of the invention can be applied to any scene needing to periodically execute actions on the network, as shown in fig. 2, the first network element transmits the configuration information to the second network element through the PCEP, and the second network element performs corresponding analysis and execution after receiving the configuration information, wherein the number of the second network elements may be multiple, and the functions of each second network element are not necessarily the same.
Based on this, the first network element determines a second network element capable of executing an action corresponding to the PCEP configuration information; and sending the PCEP configuration information to the determined at least one second network element.
And the second network element executes corresponding actions in corresponding periods according to the configuration information executed by the periodic network actions.

and when the determined time node in each period arrives, executing the periodic network action in the time length corresponding to each time node in each period.
Optionally, besides the configuration information of the periodic network action execution, the PCEP configuration information may include, but is not limited to, part or all of the following:
matching rules for a flow, actions that need to be taken on flows that match the rules.
Correspondingly, the second network element matches each received flow according to the flow matching rule, and for the matched flow, according to the action information which needs to be taken for the flow matched with the rule in the PCEP configuration information, it knows which action is taken for the matched flow, and finally, according to the configuration information executed by the periodic network action, it knows when to take the corresponding action.
