In some embodiments of the present invention, referring to fig. 8, fig. 8 is a schematic flow chart of an alternative method for storing and accessing fault recording data according to an embodiment of the present invention, and after step S105, S106 to S107 are further included. The steps shown in fig. 8 will be described.
S106, receiving a second external data access request through the first processing plug-in.
In some embodiments of the invention, the second external data access request refers to a request to access compressed data within the second processing plug-in.
In some embodiments of the present invention, the terminal may receive an external data access request through the first processing plug-in, i.e. a request to access compressed data inside the second processing plug-in.
S107, compressed data in the second processing plug-in is acquired through the first processing plug-in based on the network file system NFS service in response to the second external data access request.
In some embodiments of the present invention, the network file system, english Network File System (NFS), is a UNIX presentation layer protocol (presentation layer protocol) developed by SUN corporation, which enables users to access files elsewhere on the network as if they were using their own computer. NFS is one of the currently mainstream heterogeneous platform shared file systems. The method is mainly applied to the UNIX/LINUX environment. Originally developed by Sun Microsystems, the system can support file sharing among different types of systems through a network, is widely applied to heterogeneous operating system platforms such as FreeBSD, SCO, solaris, and allows one system to share directories and files with other people on the network. By using NFS, users and programs can access files on a remote system like local files, enabling nodes of each computer to use resources on the network as conveniently as local resources. NFS can be used for remote access and sharing of network files in different types of computers, operating systems, network architectures, and transport protocol operating environments.
In some embodiments of the present invention, NFS operates on the principle of using a client/server architecture, consisting of one client program and one server program. The server program provides access to the file system to other computers, a process called export. NFS client programs "transport" shared file systems out of NFS servers when they access them. NFS transport protocol is used for file access and shared communication between a server and a client, thereby enabling the client to remotely access data stored on a storage device. The first processing plug-in is equivalent to a client, and the second processing plug-in is equivalent to a server.
In some embodiments of the present invention, the terminal may obtain, by the first processing plug-in, compressed data within the second processing plug-in by deploying network file systems NFS on the first processing plug-in and the second processing plug-in, respectively, and then by the NFS service.
It will be appreciated that in some embodiments of the invention, the terminal may receive a second external data access request through the first processing plug-in; and responding to the second external data access request, acquiring the compressed data in the second processing plug-in through the first processing plug-in based on the network file system NFS service, and realizing external access to the compressed data.
In some embodiments of the present invention, in response to the second external data access request, obtaining, via the first processing plug-in, the compressed data within the second processing plug-in based on the network file system NFS service may be implemented by S1071 as follows:
s1071, responding to a second external data access request, and realizing NFS service and Remote Procedure Call (RPC) service through a first processing plug-in unit by a connection channel to access compressed data in the second processing plug-in unit; the connection channel is established based on the network protocol of the first processing plug-in and the network protocol of the second processing plug-in.
In some embodiments of the present invention, NFS is a UDP/IP protocol based application implemented primarily using remote procedure call RPC mechanisms, which provide a set of operations to access remote files independent of machine, operating system, and low-level transport protocols. The RPC employs XDR support. XDR is a machine-independent protocol for data description encoding that encodes and decodes data transmitted over the network in a format that is independent of any machine architecture, supporting the transfer of data between heterogeneous systems.
In some embodiments of the invention, the network protocol uses the TCP/IP protocol. The TCP/IP protocol, the Transmission control/network protocol, is also known as the network communication protocol. It is the most basic communication protocol in use of the network. The TCP/IP transport protocol specifies the standards and methods for communicating portions of the internet. And, TCP/IP transmission protocol is two important protocols that guarantee the timely, complete transmission of network data information. The TCP/IP transport protocol is strictly a four-layer architecture comprising: an application layer, a transport layer, a network layer, and a data link layer. The main protocols of the application layer include Telnet, FTP, SMTP, etc. for receiving data from the transmission layer or transmitting data to the transmission layer according to different application requirements and modes; the main protocols of the transmission layer include UDP and TCP, which are channels for combining the user platform with the internal data of the computer information network, so that the data transmission and the data sharing can be realized; the main protocol of the network layer is ICMP, IP, IGMP, which is mainly responsible for the transmission of data packets in the network; the network access layer, also called network interface layer or data link layer, has ARP and RARP as main protocol, and has the main functions of providing link management error detection, effectively processing the information detail problems related to different communication media, etc.
In some embodiments of the present invention, the terminal may access the compressed data in the second processing plug-in through the RPC service in the first processing plug-in, through the connection channel, and through the NFS service in the second processing plug-in.
In some embodiments of the present invention, step S1071 may be implemented by S10711 and S10712 as follows:
s10711, in response to the second external data access request, extracting, by the NFS service, the compressed data in the second processing plug-in.
In some embodiments of the present invention, the terminal may perform local file access through the NFS service, thereby extracting the compressed data in the second processing plug-in.
And S10712, transmitting the compressed data to the first processing plug-in unit through the RPC service, and thus completing the access of the compressed data in the second processing plug-in unit.
In some embodiments of the present invention, the terminal may transfer the extracted compressed data to the RPC service in the first processing plug-in through the connection channel by using the RPC service in the second processing plug-in, so as to complete access of the compressed data in the second processing plug-in.
