Description
Technical Field
The present invention relates to the field of information management of communication equipment, and in particular, to a method and a system for managing information related to a port in communication equipment.
Background
The communication access equipment communicates by using a plurality of ports, and the communication access equipment is interconnected with other communication equipment or connected with user terminal equipment through the ports. Therefore, the communication access device needs to manage all ports (including physical ports and logical ports), that is, manage with the information management system. This management of the information management system includes both management of aspects of system control such as port attributes, status, etc.; but also traffic-wise, wherein generally all port-based traffic data associated therewith in a communication access device needs to be organized and managed.
The contents managed by the port based information managed by the information management system in these various applications are collectively referred to as port information.
The information management of the port information greatly affects the implementation of various functional units in the communication device, and ultimately affects the stability, expandability, maintainability, etc. of the system or service function.
In the prior art, an information management system of a communication access device often uses a data structure mode of a static array or a linked list to manage port information, however, with the continuous development of the communication access device, the data structure of the static array or the linked list is difficult to adapt to new requirements in more and more application occasions.
That is to say, the development of modern communication access devices, especially broadband access devices, presents the characteristics of large quantity, high integration level and diversification, and the port information management system of the existing communication access device cannot meet the requirements.
1) As the number of ports of communication access devices continues to increase, existing information management systems consume a large amount of resources.
Compared with other communication equipment, the number of user ports of the broadband access equipment is originally large; with the development of new technologies, the integration level of device ports is continuously increased, and the total number of ports in the system is also increased. In the face of a huge number of ports, the static port information management method consumes a large amount of memory, especially some services with complicated port information.
2) With the continuous improvement of the integration level of the line card port of the communication access device, the existing information management system has poor expandability and is difficult to adjust according to the change of services.
A line card of a communication access device is a device interface between an access line and an access device of a switch, router, or other network device, and may be used to connect a cable or fiber line.
When a line card port of a communication access device is managed in a static manner, a maximum port number of a line card is usually defined in an information management system, and meanwhile, for port application in the line card, when a memory of port information is allocated, the memory is also allocated according to the maximum port number of the line card. However, as the integration of the line card in the communication access device increases, the maximum port number of the line card defined by the port information management system of the communication access device must be correspondingly increased, and the implementation code must be correspondingly adjusted, at this time, the limitation of the maximum port number makes the expandability of the information management system poor, and it is difficult to adjust according to the change of the service.
3) With the diversification of port access modes of communication access equipment, the existing information management system cannot adapt to diversified management and also brings about the problem of expandability.
Different types of line cards often have different port types and port densities for communication access equipment. This also makes it difficult to organize the port information in a static manner in the design. Also, the continuous emergence of new types of line cards raises issues of system scalability.
Therefore, in many cases, the port information management system in the static mode cannot meet the requirement of the port information management of the communication access device.

When the port information is inquired at the line card port, the content of the tree node of the corresponding port in the binary tree (port information tree) of the dynamic linked list corresponding to the line card port is inquired in the dynamic linked list tree database correspondingly.
When the port information is modified at the line card port, the content of the tree node of the corresponding port in the binary tree (port information tree) of the dynamic linked list corresponding to the line card port is correspondingly modified in the dynamic linked list tree database.

step S2201, positioning to a corresponding root node according to a binary tree corresponding to the line card, and then searching for a node corresponding to the port on the binary tree;
step S2202, judging whether the search result is found;
step 2203, if not found, the port information node is created and inserted into the binary tree, and the configuration information is recorded into the port information node;

in step S2304, if found, the node is deleted.
Step S2305, further, when the line card is deleted, all nodes in the binary tree corresponding to the line card are deleted, and the tree root node pointer is NULL (NULL).
As shown in fig. 5, the following description will be made by taking an example of managing multicast service port authentication information using a dynamic linked list tree database.
The dynamic chain table tree database TreeTable [ shelf ] [ slot ] is a two-dimensional array with a frame and a slot of the communication access equipment as subscripts, and each array member is a binary tree (port information tree) root node pointer corresponding to a corresponding line card. The pointer is initially NULL.
Each node of the binary tree (port information tree) contains the following parts:

PortAttr: and the port information is used for storing various port related information according to different applications. The embodiment of the invention relates to multicast port authentication information.
When multicast authentication information is configured for a line card port (identified by PortId), firstly, a corresponding information tree root node is positioned according to the 'shelf' and 'slot' of the line card, and then a node corresponding to the port is searched on an information tree. If not, the node is created for insertion into the binary tree and the configuration information is entered into the PortAttr of the node. If found, the PortAttr configuration information in the node is modified directly.
On the contrary, when the multicast authentication information of a certain port is to be deleted, the slot is positioned to the root node of the corresponding information tree according to the shelf of the line card, and then the node corresponding to the port is searched on the information tree. If not found, go back directly. If so, the node is deleted.
When the line card is deleted, all nodes on the binary tree corresponding to the line card are deleted, and the tree root node pointer is set to NULL.
When the port authentication configuration information is inquired, the slot is positioned to the root node of the corresponding information tree according to the shelf of the line card, and then the node corresponding to the port is searched through the binary tree to obtain the configuration information.
As shown in fig. 6, the port information management system of the communication device of the present invention is explained in detail below:
the port information management system 60 of the communication device of the present invention includes a dynamic link table tree database unit 61 and a port information management unit 62. Wherein,
the dynamic linked list tree database unit 61 is configured to create and store a dynamic linked list tree database of port information of a line card in the communication access device according to the line card port information in the communication access device.
The dynamic linked list tree database takes the line card information of the communication access equipment as a two-dimensional array of the subscript, and each array member is a binary tree (port information tree) root node pointer corresponding to the corresponding line card. The pointer is initially NULL (NULL).
Each node of the binary tree (port information tree) contains the following parts:
connecting words: used for connecting each node in the binary tree;
and the port index is used for identifying the port and can be used as a key (key) when the binary tree is traversed by the port index.
And the port information is used for storing various port related information according to different applications.
And a port information management unit 62, configured to manage port information in the dynamic linked list tree database according to operation information on the line card port in the communication access device. It includes an operation judging unit 63, a configuration information unit 64, a deletion information unit 65, and an inquiry information unit 66.
The operation determining unit 63 is configured to determine operation information of the line card port in the communication access device, and perform different operations on the port information in the dynamic linked list tree database according to different operation information.
A configuration information unit 64, configured to, when the result determined by the operation determining unit 63 is that the configuration information is configured for a line card port, perform a search determination according to a binary tree corresponding to the line card, or create a corresponding port information node, and record the configuration information into the port information node; or modify configuration information of the corresponding port information node.
And a delete information unit 65, configured to, when the operation judgment unit 63 judges that the result is the port information of the port to be deleted, perform a search judgment according to the binary tree corresponding to the line card, and delete the node after finding the port information node corresponding to the port.
And if all nodes on the binary tree corresponding to the line card are deleted when the line card is deleted, the pointer of the tree root node is NULL (NULL).
And the query information unit 66 is configured to, when the result determined by the operation determination unit is query port configuration information, perform traversal according to the binary tree corresponding to the line card to search for a corresponding port information node, and acquire configuration information of a corresponding port.
The port information management system 60 of the communication equipment of the present invention utilizes the dynamic linked list tree database unit 61 to form a dynamic linked list tree of information management of a line card by creating a dynamic linked list tree data structure for each line card in the communication access equipment, and obtains the dynamic linked list tree database of port information management of the communication access equipment.
Then, according to the operation information of the line card port in the communication access device, the port information management unit 62 manages the port information in the dynamic linked list tree database.
Firstly, the operation judging unit 63 judges the operation of the line card port in the communication access device;
then, when the result of the judgment by the operation judgment unit 63 is that the configuration information is configured for a line card port, the configuration information unit 64 performs search judgment according to the binary tree corresponding to the line card, or creates a corresponding port information node, and records the configuration information into the port information node; or modifying the configuration information of the corresponding port information node; when the operation judging unit 63 judges that the port information of the port is to be deleted, the deletion information unit performs searching judgment according to the binary tree corresponding to the line card 65, and deletes the node after finding the port information node corresponding to the port; when the operation determining unit 63 determines that the result is query port configuration information, the query information unit 66 performs traversal according to the binary tree corresponding to the line card to search for a corresponding port information node, and obtains configuration information of a corresponding port.
In practical use, the method and the system for managing the port information of the communication equipment can be used for services such as multicast authentication management of broadband access equipment and the like, and replace the original static array method, thereby solving the problem that the services such as the multicast authentication management and the like occupy too large memory due to the capacity expansion of a system logic port; and simultaneously, the problem of expansibility caused by the fact that the maximum logic port number of the line card is greatly increased after a newly added access mode (GPON) is solved.
The method and the system for managing the port information of the communication equipment have the following advantages that:
1) the port information is dynamically managed, and the memory is saved.
In many cases, the device is not fully configured; or even full configuration, for a service, not all ports need to open or configure the service. The method and the system for managing the port information of the communication equipment only establish the corresponding node for the port which is established or has service configuration, thereby effectively saving a large amount of memory.
2) Good adaptability and convenient expansion
The nature of the data structure of the binary tree dictates that there is no limit to the number of ports on each line card. The port information tree can be used for managing various line cards with different port numbers. When the integration degree of the ports of the newly added line cards or line cards is increased, the management part of the port information tree does not need to be modified. On the other hand, when the number of bus cards of the system is increased, the size of the root node pointer array is only required to be correspondingly increased so as to accommodate more binary trees.
This feature is significant in broadband access methods and technologies, and in the case of rapid development of access devices.
3) Simple and efficient
The binary tree data structure in the embodiment of the invention is ordered, and the operations of query, insertion, deletion and the like have good efficiency. Compared with a static array, the binary tree has obvious advantages in efficiency. The dynamic method uses a binary tree because the binary tree is convenient and efficient compared with other dynamic data structures, such as a sequential linked list.
On the other hand, according to the method and the system for managing the port information of the communication device in the embodiments of the present invention, a binary tree is created for each line card individually. Thus, for a port, the port can be located to the binary tree by the line card identifier first, and then the corresponding node is searched on the binary tree. Compared with the mode of placing all ports on one binary tree, the two-stage positioning mode has the advantage that the efficiency is further improved.
Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.
While particular embodiments of the present invention have been described and illustrated, such embodiments should be considered as illustrative only and not as limiting the invention, which is to be construed in accordance with the accompanying claims.
