Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a data processing method, device and equipment for local terminal equipment. Background Art

[0002] Currently, the existing network's central office equipment, OLTs (Optical Line Terminals), do not support edge computing capabilities. To measure application experience, the existing OLT must be cascaded to a new OLT with edge computing capabilities, sharing its computing power for application execution. The disadvantage of this solution is that during deployment, the uplink port of the existing OLT must be reconnected to the cascade port of the OLT with experience measurement capabilities, which is equivalent to performing a service cutover. All service traffic from the existing OLT will be uploaded to the bearer network through the OLT with experience measurement capabilities, causing service interruption. This has a significant impact on large-scale deployment in the existing network, making it difficult to implement. Summary of the Invention

[0026] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] Figure 1 FIG. 1 is a flow chart showing a data processing method of a central office device provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0028] Step 11, obtaining traffic data between the first local end device and the network;

[0029] Step 12: The traffic data is transmitted to the second local terminal device through the link between the first local terminal device and the second local terminal device, and the second local terminal device performs a measurement application experience analysis based on the traffic data; the first local terminal device is a local terminal device that does not have the function of measuring application experience analysis, and the second local terminal device is a local terminal device that has the function of measuring application experience analysis.

[0030] In this embodiment, the first local terminal device and the second local terminal device can be OLT devices. The first local terminal device is a local terminal device that does not have the function of measuring application experience analysis. Without changing the uplink link of the first local terminal device and ensuring that the service of the first local terminal device is not affected, a link is established between the first local terminal device and the second local terminal device, and the second local terminal device is hung next to the first local terminal device. The link is a physical fiber jumper connection. Through the link, the traffic data obtained between the first local terminal device and the network is transmitted to the second local terminal device, and the analysis is completed by the second local terminal device. By creating a new link, the traffic data is transmitted to the second local terminal device. Without affecting the service traffic of the first local terminal device, the traffic data can be measured and analyzed at the same time.

[0031] In an optional embodiment of the present invention, the link is a link between an uplink board of the first central office device and a cascade board of the second central office device, and step 12 includes:

[0032] The traffic data is transmitted from the uplink board of the first local terminal device to the cascade board of the second local terminal device through the link, and the cascade board transmits the traffic data to the analysis board of the second local terminal device, and the analysis board performs measurement application experience analysis based on the traffic data.

[0033] In this embodiment, without changing the uplink link of the first local terminal device, the uplink board of the first local terminal device and the cascade board of the second local terminal device are physically connected by fiber jumper, and the traffic data is transmitted from the uplink board of the first local terminal device to the cascade board of the second local terminal device through mirroring, and then forwarded by the cascade board to the analysis board of the second local terminal device for measurement and application experience analysis. Without changing the uplink link of the first local terminal device, a new link is created, and data is directed to the second local terminal device through the new link for measurement and application experience analysis, thereby avoiding the problem in the prior art where all business traffic flows through a local terminal device with a measurement and application experience analysis function, resulting in an excessive business data load on the local terminal device, causing business interruption.

[0034] In an optional embodiment of the present invention, the traffic data includes: downlink traffic data sent by the network and received by the first local end device and / or uplink traffic data sent by the first local end device to the network.

[0035] Figure 2 FIG. 1 is a flow chart showing a data processing method of a central office device provided by another embodiment of the present invention. Figure 2 As shown, the method includes the following steps:

[0036] Step 21: receiving traffic data sent by the first central office device through a link between the first central office device and the second central office device;

[0037] Step 22: the second local terminal device performs measurement application experience analysis based on the traffic data; the first local terminal device is a local terminal device without the measurement application experience analysis function, and the second local terminal device is a local terminal device with the measurement application experience analysis function.

[0038] In this embodiment, the second local-end device is a local-end device with a function for measuring application experience analysis. A link is established between the first local-end device and the second local-end device, and the second local-end device is attached to the first local-end device. The link is a physical fiber jumper connection, and traffic data sent by the first local-end device is received via the link, and the traffic data is transmitted to the second local-end device, where the second local-end device performs a measurement and application experience analysis of the traffic data. By attaching the second local-end device to the second local-end device, the traffic data of the first local-end device is diverted to the second local-end device for experience measurement analysis, without affecting existing network services.

[0039] In an optional embodiment of the present invention, the link is a link between an uplink board of the first central office device and a cascade board of the second central office device, and step 22 includes:

[0040] The cascade board of the second local end device receives the flow data sent by the first local end device from the uplink board of the first local end device, and transmits the flow data to the analysis board of the second local end device.

[0041] In this embodiment, the upstream board of the first local end device and the cascade board of the second local end device are connected by a physical fiber jumper, i.e., the link; the traffic data of the upstream board is mirrored to the cascade board through the link, and then sent by the cascade board to the analysis board of the second local segment device for analysis.

[0042] In an optional embodiment of the present invention, the second local end device performs application experience measurement analysis based on the traffic data, including:

[0043] Determine the uplink or downlink direction of the traffic data; and perform a measurement application experience analysis on the determined uplink traffic data or downlink traffic data.

[0044] In this embodiment, when the flow data of the first local-end device is mirrored to the second local-end device through the link for analysis, since the second local-end device is hung next to the first local-end device, the flow data mirrored to the cascade board of the second local-end device are all horizontal data. When the cascade board sends the flow data to the analysis board, the analysis board cannot distinguish the direction of the flow data. At this time, the analysis board needs to analyze the flow data in the upstream or downstream direction.

[0045] Further, determining the uplink or downlink direction of the traffic data includes:

[0046] Step 31: Obtain a mapping relationship between N first devices and M second devices, where both the first devices and the second devices are connected to the analysis board; N and M are both positive integers, and N is greater than M;

[0047] Step 32: Obtain a source MAC address and a destination MAC address of a traffic data packet transmitted from the first device to the second device;

[0048] Step 33: When it is determined, based on the mapping relationship, that the number of destination MAC addresses corresponding to a source MAC address is greater than a preset threshold, the source MAC address is determined to be the MAC address of the first device, the destination MAC address is the address of the second device, and the direction of the traffic data is upstream; otherwise, the direction of the traffic data is downstream.

[0049] The following is a concrete example to illustrate the implementation of the above method:

[0050] like Figure 3 As shown in the figure, according to the actual situation of the existing network, you can configure the maximum number of broadband remote access servers (BRAS) that each dial-up user can register with. This value is set to M.

[0051] The analysis board of the second-end device analyzes each connection through the Point-to-Point Protocol over Ethernet (PPPOE), collects statistics based on the source MAC address and destination MAC address of the message, and learns a mapping relationship between N and M, that is, N MAC addresses correspond to M MAC addresses, and N is much larger than M.

[0052] A preset threshold, X, is set. When the number of MAC addresses learned for a MAC address that is greater than X, the MAC address is considered the MAC address of the BRAS, and the corresponding MAC address of the other end is the MAC address of the user. The MAC addresses of all BRASs in the entire network are automatically learned in sequence, allowing the system to distinguish whether packets are flowing from users (ONTs / APs / routers) to the BRAS or from the BRAS to users. Packets flowing from users to BRASs are considered uplink packets, while packets flowing from BRASs to users are considered downlink packets. ONTs are optical network devices, and APs are wireless access points.

[0053] In this embodiment, message direction is automatically learned by analyzing the message, eliminating the need for manual static configuration of each device to determine the message direction, significantly reducing deployment and maintenance difficulties. Furthermore, this learning mechanism is refreshed periodically to ensure that new BRASs can be quickly learned when deployed in the network.

[0054] The above embodiments of the present invention do not require service cutover when analyzing the user experience of existing networks. Instead, traffic from the existing OLT can be directed to an OLT with analysis capabilities, thus avoiding affecting services and degrading user experience.
