Description

IP address allocation management system and method thereof
Technical Field
The invention relates to the field of coaxial network signal transmission IP address allocation management, in particular to an IP address allocation management system and a method thereof.
Background
Broadcast television network operators are facing a key phase of changing from the original radio frequency signaling mode to the IP network signaling mode. The broadcast television network mainly uses a coaxial network for signal transmission, and a plurality of coaxial transmission technologies may exist in one area, so that terminals are different, and authentication and IP allocation manners are different.
The broadband and interactive television service of the current main operation of the radio and television mainly adopts a DHCP + identification code authentication technology, and an IP address and a configuration file need to be acquired through a DHCP system so as to activate and configure a CableModem (CM cable modem). The activated CM can receive signals according to a specific frequency and convert the signals into IP packets for transmission; meanwhile, in order to identify the radio and television terminal, the Option conventional parameter and the extension custom parameter in the DHCP protocol are generally used for identification and authentication. The DHCP obtains a Media Access Control Address (MAC) and an Option parameter through a request of the terminal, and checks user data, and in this process, the DHCP needs to obtain service package right data of a user from an LDAP (lightweight directory Access protocol) server. User data is written by the BOSS system in incremental synchronization. And when the verification is finished, the DHCP server allocates a corresponding service IP address and a terminal service package configuration file, so that the processes of user terminal authentication and service opening are finished. Therefore, the robustness of the LDAP data server is crucial for the service stable operation of the broadcast television network operator.
The broadcast television network mainly uses the coaxial network for signal transmission, and uses the IP address allocation System as the main mode of IP allocation and terminal authentication, and the user data is centrally stored in the independent LDAP server, wherein, the BOSS System (Business & Operation Support System) directly writes the user data into the LDAP server, and the DHCP server also directly reads the LDAP server, i.e. the read-write Operation of the LDAP server is not separated as shown in fig. 1. Structurally, the problem of single-point failure exists in the user data stored in a centralized manner, and due to the characteristics of the LDAP server, the performance of writing the data by the LDAP server is poor, so that the recovery time is too long after the data server fails and the user data is lost, and the user data is not suitable for the operation level requirement.
In addition, because the DHCP server needs to query and check the LDAP server after receiving the terminal DHCP request, authentication failure may also be caused if the network communication between the DHCP server and the LDAP server fails.
Disclosure of Invention
The invention aims to provide an IP address allocation management system and method capable of rapidly recovering corresponding services.
The IP address allocation management system of the invention comprises:
the data synchronization module is used for receiving user data written into the LDAP server by the BOSS system and subjected to strategy identification, and synchronizing the user data subjected to strategy identification to a database of the DHCP core management server for storage;

and the DHCP server is used for receiving a DHCP request forwarded by a terminal (Cable Modem Cable Modem) through a CMTS (Cable Modem termination System Cable Modem terminal System) or an EOC (Ethernet Over Cable Ethernet data transmission through a coaxial Cable) coaxial network, inquiring and authenticating user data in a file database of the DHCP server of the node according to the DHCP request, and if the authentication is passed, allocating an IP address to the corresponding terminal and issuing a configuration file and authorization information.
The invention discloses an IP address allocation management method, which comprises the following steps:
acquiring user data written by a BOSS system into an LDAP server for strategy identification, and synchronizing the user data subjected to strategy identification into a database of a DHCP core management server for storage;
synchronizing the user data subjected to the strategy identification in the database into a memory of a DHCP core management server, and synchronizing the user data in the memory of the DHCP core management server to a file database of a DHCP server of each next-level node for storage according to the strategy identification;
and inquiring and authenticating the user data in the file database of the DHCP server of the node according to the DHCP request forwarded by the terminal through the CMTS or the EOC coaxial network, and if the user data passes the authentication, allocating an IP address to the corresponding terminal and issuing a configuration file and authorization information.
The IP address distribution management system and the method thereof of the invention, through neutralizing the user data which is marked by the strategy in the database of the DHCP core management server, and synchronizing the user data to the file database of the DHCP server of each next level node according to the strategy mark to carry out secondary cache processing, the DHCP server of each level node can quickly carry out the inquiry authentication of the user data after receiving the DHCP request, distribute the IP address to the corresponding terminal, and issue the configuration file and the authorization information, because the DHCP server of each node has the user data of the service object, when the user terminal initiates the DHCP request, the DHCP server node can complete the verification through the local user data inquiry and distribute the IP address and the configuration file without inquiring the user database of the LDAP server and the BOSS system background through the network, therefore, the writing speed of the user data can be effectively improved, and the corresponding service can be quickly recovered when a fault occurs, so as to achieve the effect of improving the service response quality.

Detailed Description
As shown in fig. 2, an IP address allocation management system includes:
the data synchronization module is used for receiving user data written into the LDAP server by the BOSS system and subjected to strategy identification, and synchronizing the user data subjected to strategy identification to a database of the DHCP core management server for storage; the data synchronization module also regularly scans the user data identified by the strategy on the LDAP server in a full scanning mode, updates the user data identified by the strategy in the DHCP core management server database according to the increment or decrement of the scanning result, and synchronizes the user data identified by the strategy to the DHCP core management server database for storage.
The database is used for storing the user data identified by the strategy;
the data distribution module is used for calling the user data identified by the strategy in the DHCP core management server database, synchronizing the user data identified by the strategy into the memory of the DHCP core management server, and synchronizing the user data in the memory of the DHCP core management server into the file database of the DHCP server of each next-stage node for storage according to the strategy identification;
and the DHCP server is used for receiving a DHCP request forwarded by the terminal through a CMTS (CMTS or EOC) equivalent axis network, inquiring and authenticating user data in a file database of the DHCP server of the node according to the DHCP request, distributing an IP (Internet protocol) address to the corresponding terminal if the authentication is passed, and issuing a configuration file and authorization information.
The strategy mark comprises a user area mark or a service type mark, and the data distribution module synchronizes user data stored in the DHCP core management server to the file database of the DHCP server of each next-level node for storage according to the user area mark or the service type mark.
As shown in fig. 3, an IP address allocation management method includes:
acquiring user data written by a BOSS system into an LDAP server for strategy identification, and synchronizing the user data subjected to strategy identification into a database of a DHCP core management server for storage;
synchronizing the user data subjected to the strategy identification in the database into a memory of a DHCP core management server, and synchronizing the user data in the memory of the DHCP core management server to a file database of a DHCP server of each next-level node for storage according to the strategy identification;
and inquiring and authenticating the user data in the file database of the DHCP server of the node according to the DHCP request forwarded by the terminal through the CMTS or EOC equivalent axis network, and if the user data passes the authentication, allocating an IP address to the corresponding terminal and issuing a configuration file and authorization information. For a single user profile query (random query) in a node, for example, the average response time of a DHCP server under a single-core Intel (R) Xeon (R) X3430@2.40GHzCPU system is close to 10us when 1000 user queries are made per second; when the server based on the original structure is used for query, the average response time is more than 1ms, the query efficiency is obviously improved, the read-write of the new structure is comprehensively decoupled and separated, the continuous concurrent query is more stable, and the server based on the original LDAP protocol structure is easy to crash and fail when being read and written simultaneously.
Before obtaining the user data written by the BOSS system into the LDAP server for policy identification and synchronizing the user data for policy identification to the database of the DHCP core management server for storage, the method also comprises the following steps: and periodically scanning the user data identified by the strategy on the LDAP server in a full scanning mode, and updating the user data identified by the strategy in the DHCP core management server database according to the increment or decrement of the scanning result. For example, the DHCP core management server measures the time for 100 million LDAP users to read in full volume (batch and sequential query) in a system with 8-core Intel (R) Xeon (R) E5-2650v3@2.30GHzCPU, which is about 1 minute.
The strategy mark comprises a user area mark or a service type mark, and the data distribution module synchronizes user data stored in the DHCP core management server to the file database of the DHCP server of each next-level node for storage according to the user area mark or the service type mark. The user data under different user area identifications are synchronized to different zone groups, and because the strategy identifications are written in the user data in advance, the data distribution module can distribute the user data to DHCP servers of different nodes according to the zone groups when processing and distributing the user data.
