Description
Technical Field

Background
The IETF DetNet working group proposes a specified period queuing forwarding (Cycle Specified Queuing and Forwarding, CSQF) and a Large scale deterministic network IP technique (Large-scale Deterministic IP Network, LDN) that does not require full network time synchronization, only frequency synchronization, and can provide deterministic transport services for critical traffic.
In the periodic scheduling forwarding model, when a controller performs end-to-end path planning on deterministic service, accurate time delay of a physical link needs to be acquired, but in practical application, an optical fiber is influenced by factors such as environment temperature and humidity, carrier frequency, curvature and the like; in order to improve the measurement accuracy of the link delay, a special network optical frequency domain reflectometer (Optical Frequency Domain Reflectometer, OFDR) and other devices are generally selected to measure the physical delay of the optical fiber, and the measurement process is not required to be repeated under the condition that the optical fiber path is not jumped.

When the optical fiber link hops, the link delay may change, but at this time, the user and the control plane cannot acquire and respond to the link hops in time, and thus the accuracy of end-to-end path planning cannot be guaranteed.
Aiming at the problems that the link cannot be detected in time when the link hops in the related art, an effective solution is not provided.

step S302: and transmitting the jump detection message to a second communication node to instruct the second communication node to determine the position offset of the jump detection message transmitted by the first communication node in a period template window of the second communication node, and transmitting a link jump notification message under the condition that the change value of the position offset is larger than a preset threshold value, wherein the change value of the position offset is the difference value between the position offset and the position offset determined last time.
Through the steps, the second communication node is instructed to determine the position offset of the jump detection message sent by the first communication node in the periodic template window of the second communication node by sending the jump detection message to the second communication node, and a link jump notification message is sent under the condition that the change value of the position offset is larger than a preset threshold value; the problem that in the related art, when a link hops, the link can not be detected in time is solved, and the effect that the link hops can be detected in time is achieved.
Optionally, the above step S302 is performed: before sending the jump detection message to the second communication node, the method further comprises: determining a plurality of period templates supported by the second communication node and the first communication node; determining a target period template from the plurality of period templates, and determining a preset sending interval of the jump detection message according to the target period template, wherein the preset sending interval is an integer multiple of the time slot length of the period template.

The principle of the above link hopping detection procedure is described below with reference to fig. 5, and fig. 5 is a schematic diagram of an alternative link hopping detection principle according to an embodiment of the present invention, as shown in fig. 5:
when the jump detection message arrives at the downstream node, the offset value is calculated and stored according to the selected periodic template, and as the subsequent detection message arrives continuously, the downstream node sets a threshold delta according to the change condition of the offset value, if the change quantity of the offset value exceeds delta, the optical fiber link is considered to be possibly jumped, and a corresponding link jump notification message is sent out. It can be seen that in fig. 5, the values of offset1 and offset2 are less than δ, and thus no link jump is assumed to occur, while the value of offset3 is greater than δ, and thus a link jump is assumed to occur.
Further, the following description is made with reference to fig. 6, and fig. 6 is a flowchart of an alternative link hopping detection according to an embodiment of the present invention, as shown in fig. 6, specifically including the following steps:
step 1: activating a link jump detection function of the network equipment, and designating the sending frequency of a jump detection message and a selected period template;
it should be noted that, the sending frequency of the detection message of the upstream node may be flexibly specified by the user, and particularly, since the detection message needs to be sent at the beginning or ending time of the window, the sending interval of the detection message must be an integer multiple of the time slot length T, for example, when t=20us, the sending frequency of the measurement message may be set to 20us,40us,60us, and so on, which is not limited in this application.
It should be noted that, if the upstream and downstream devices support multiple periodic templates at the same time, in order to increase the measurement frequency, a window of the smallest periodic template may be selected as a reference to send a detection message, and the detection message needs to carry the selected periodic template.
Step 2: the upstream node constructs a link jump detection message according to the specified periodic template;
step 3: the downstream node sends a measurement message at the beginning time of the periodic template window according to the designated frequency;
step 4: the downstream node receives the detection message, if the detection message is the first detection message, the deviation value (corresponding to the position offset) in the designated period is calculated and stored, the jump difference value (corresponding to the position offset) is set to 0, and the step 7 is executed; otherwise, calculating the value of the offset and comparing with the locally stored value of the offset;
step 5: if the offset value of the calculated offset value and the locally stored offset value does not exceed the threshold delta, setting the jump value to 0, and executing the step 7;
the value of δ may be determined comprehensively according to the actual environmental temperature and humidity change, the optical fiber load change, the optical fiber length, etc., and the value of δ may be an absolute value or a ratio, which is not limited in this application.
Step 6: updating the stored offset value and the hopping difference value, and sending out a link hopping notification message;
when the downstream node detects that the jump occurs, the link jump behavior and the jump deviation value are optionally notified to the upstream node or the controller, and then the upstream node or the controller can trigger or notify the user to re-measure the optical fiber link delay. Specifically, the advertised information at least includes an address or an interface capable of identifying the home network device, an address or an interface capable of identifying the peer network device, a period size, a hopping flag, a hopping difference value, and the like. The invention does not limit the information notification mode, for example, the information notification can be sent to other nodes of the network by extending the attribute notification of IGP (OSPF, ISIS) and BGP, and the information notification can also be sent to the controller by extending the southbound interface (such as NETCONF, BGPCEP, BGP-LS, etc.).
Step 7: and finishing the jump detection.
Through the steps, when the upstream node sends the jump detection message, determining the position offset of the jump detection message sent by the upstream node in a period template window of the second communication node, and sending a link jump notification message under the condition that the change value of the position offset is larger than a preset threshold value; therefore, when the link hops, the link can be obtained in time; therefore, the problem that the link cannot be detected in time when the link hops in the related technology can be solved, and the effect of detecting the link hops in time is achieved.
In order to facilitate better understanding of the technical solution, the present application further provides the following examples to describe the technical solution.
Example 1
The scheme of embodiment 1 is described below with reference to fig. 7 and 8, where fig. 7 is a schematic diagram of another alternative optical fiber link hopping according to an embodiment of the present invention, and fig. 8 is a flowchart of another alternative link hopping detection according to an embodiment of the present invention.
As shown in fig. 7, in this embodiment, it is assumed that there are two network devices N1 and N2, where the two devices are frequency-synchronized but time-unsynchronized, in the traffic direction N1- > N2, a is an upstream device node, N2 is a downstream device node, and both the N1 and N2 devices support 3 cycle templates, respectively A, B, C, with cycle template slot lengths of 10us,20us, and 40us, respectively. In N1, the slot length of the periodic template a is selected as the transmission interval of the detection message, that is, the transmission interval of the jump detection message is 10us. In N2, a threshold δ of jump detection is set to 500ns. The phase difference delta between the two devices is 5us, the optical fiber time delay is 12us, after the 2 nd detection message is sent out by the N1, the link hops, the optical fiber time delay after the hopping is 18us, and according to the prior art, the first three detection messages reach the offset value offset of the N2 node falling in the window.
The general flow of the jump detection at this time is shown in fig. 8, and includes the following steps:
step 1: activating the jump detection test function of the N1 and N2 nodes, wherein the message sending frequency is 10us, and a periodic template is selected as an A template;
step 2: the N1 node constructs and sends a detection message at intervals of 10us at the beginning time of the A template window;
step 3: the N2 node receives the 1 st detection message, calculates an offset value of 7us, stores the offset value in the local area, and sets the jump difference value to 0;
step 4: the N2 node receives the 2 nd detection message, calculates an offset value to be 7us, calculates the deviation from the stored offset value, and does not exceed a threshold delta=500 ns;
step 5: the N2 node receives the 3 rd detection message, calculates an offset value to be 3us, calculates an offset value to be 4us with stored offset, and exceeds a threshold delta=500 ns;
step 6: updating the stored offset value to 3us, and updating the jump deviation to 3us;
step 7: and sending out a link jump notification message.
Through the steps, when the first communication node sends the jump detection message, the position offset of the jump detection message sent by the first communication node in the periodic template window of the second communication node is determined; and sending a link jump notification message under the condition that the change value of the position offset used for indicating the difference value between the position offset and the position offset determined last time is larger than a preset threshold value; therefore, when the link hops, the link can be obtained in time; therefore, the problem that the link cannot be detected in time when the link hops in the related technology can be solved, and the effect of detecting the link hops in time is achieved.
Example 2
The following describes the present embodiment with reference to fig. 9, and fig. 9 is a schematic diagram of an encapsulation format of an optional link hopping advertisement packet according to an embodiment of the present invention;
the embodiment provides an example of encapsulation of a link hopping information notification message, for example, OSPF may be extended, and a link attribute sub-TLV called link-switch sub-TLV may be added to carry information about a link hopping between two devices associated with the link, where the information includes an offset value and a hop offset-detection before and after a link hopping, and an encapsulation schematic format is shown in fig. 9:
wherein, the type field uses a specific value to indicate that the sub-TLV is a link jump deviation attribute type, the length field indicates the length of the sub-TLV data part, the value is 8, the cycle-template field is used for specifying the time slot length of the selected cycle template, for example, the length of the field is 2Octets, and the cycle template A is 10 us; pre-offset values before hopping, 2Octets, post-offset values after hopping, 2Octets; the offset-detection before and after hopping occupies 2Octets.
