Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
As shown in fig. 1, the present invention provides a burst traffic detection method based on slice in a PON system, including:
s1, receiving burst flow detection template configuration of an OLT slice executed by a user and template binding related operations related to the slice or objects in the slice, and configuring a burst flow detection template for the OLT slice;
in a multi-slice scenario, each slice is virtualized into an independent network element with independent service configuration. The user may create a respective burst traffic detection template for each slice, and directly bind to the slice or to a subordinate object belonging to the slice (e.g., a PON interface belonging to the slice or an ONU), and the functions are independent from each other and only valid in the scope of the slice.
In different slices, the data flow classification modes of the burst flow detection template can be consistent (for example, the same Ethernet type is used for data flow classification), but the threshold values can be different, and the alarm strategies can also be different, so that the slice-based differential management is realized.
The burst flow detection template comprises a flow classification template and a strategy template; the flow classification template mainly defines one or more data flows to be detected through a data packet five-tuple (generally referred to as a source IP address, a source port, a destination IP address, a destination port and a transport layer protocol); the strategy template is matched with the flow classification template to define the processing strategy of the data flow, and the content comprises the following steps: burst traffic is on-line (generate alarm), burst traffic is off-line (end alarm), and alarm server address.
The burst flow detection template can be bound on different objects to realize burst flow monitoring on the objects (the objects can be whole slices or be specific members belonging to the slices). Receiving burst traffic detection configuration executed by a user and template binding related operations (such as binding, modifying or deleting of a burst traffic detection flow template, migration operations of objects among slices and the like) related to the slices or objects in the slices;
further, the configuration may be subjected to a validity check, which includes: whether the slicing and burst flow detection template reaches the maximum configuration upper limit, whether the flow classification, the threshold value and other parameters are in a legal range, and the like;
and also judging whether the configuration relates to template binding related operation of the slice or the object in the slice, if so, transmitting the template binding related operation to a slice logic processing unit, and processing the subsequent flow by the logic processing unit;
s2, according to the template binding related operation related to the slice or the object in the slice, executing the corresponding template binding related operation;
when the burst flow detection template is changed or deleted, the association relationship between the template and all slices needs to be identified, and batch operation is carried out on the slices associated with the burst flow detection template;
furthermore, the slice logic processing unit also performs a template binding related operation pair to perform validity check, wherein the validity check includes whether a newly added burst flow detection template has logic conflict with an existing template or not;
s3, according to the burst flow detection template configured by the OLT slice, carrying out flow detection on the slice or the object in the slice, and if the data flow of the detection object is greater than the threshold value configured by the burst flow detection template, generating a flow alarm indication;
when the system generates burst flow acquisition data or alarm information, the slice attribute of the generated object needs to be identified, and the slice is reported according to the management configuration attribute of the slice.
When the object bound by the burst flow detection template migrates in different slices, the related functions can be automatically activated according to the burst flow detection template configured by the target slice, and manual configuration is not needed. For example: and the target slice is bound with a burst flow detection strategy based on the whole slice, so that after a new member is migrated, the uplink and downlink data streams of the object carry specific slice information, and the burst flow detection strategy automatically takes effect for the new member without manual configuration.
S4, judging whether the object generating the alarm as the exclusive resource belongs to a slice, if the object generating the alarm as the exclusive resource belongs to a slice, reporting the alarm by the management parameter configured by the slice; and if the object generating the alarm as the shared resource belongs to a plurality of slices, reporting the alarm according to the management parameters configured by each slice.
The invention takes the slice ID as the configuration parameter and the detection parameter of the burst flow detection, realizes the burst flow detection template configuration based on the slice, and the burst flow detection and processing strategy based on the slice.

the flow classification template 2 and the strategy template 3 are bound on the upper joint port 1 in the slice 1 and act on all objects under the upper joint port 1;

In the embodiment of the invention, the PON object is represented by PON x/y/z, the ONU object is represented by ONU x/y/z/a, and the x/y/z/a is an object identifier and respectively represents a subframe number/a slot number/a PON port number/an ONU number. In the example of fig. 2, the upstream port and the PON port are of one level, and the ONU belongs below the PON port.
In the embodiment of the present invention, the configuration of the lower node and the configuration of the upper node may coexist, for example, the ONU0/1/1/8 under the PON0/1/1 has a data flow configuration for vlan id of 100, the ONU PON0/1/1 has a data flow configuration for vlan id of 1000, these two rules do not conflict, both the upstream flows entering from the ONU0/1/1/8 will take effect according to the configuration, only the effective positions are different, the data flow for vlan id of 1000 takes effect at the PON0/1/1, and the data flow for vlan id of 100 takes effect at the ONU 0/1/1/8.

the flow classification template 1 is: VLANID of 100;
the flow classification template 2 is: VLANID 200& EthType 0x 0800;
the flow classification template 3 is: SRC Ipaddr 192.168.100.1
The strategy template 1 is: 1. the burst flow is on line 50M, and an alarm is generated; 2. and (3) taking off the line for 30M of burst flow, ending the alarm 3, and the alarm server: 192.168.101.1, respectively;
the strategy template 2 is: 1. the burst flow is on line for 200M, and an alarm is generated; 2. the burst flow rate is offline for 150M, and the alarm is ended; 3. and (4) an alarm server: 192.168.103.1, respectively;
