Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
The embodiment provides a high-performance network communication library implemented based on ZeroC ICE, which includes: using a communication architecture of a zeroC ICE as a bottom layer framework of a high-performance network communication library; a network topology connection creation program for creating a network topology connection according to the configuration; a data retransmission program for ensuring the integrity of data in the communication process; and storing the data in the communication process, and taking out the data reading and storing program of the data when in use.
Wherein, zeroC ICE uses compact, high-efficiency binary protocol to minimize CPU and bandwidth consumption, IDL Slice of ICE is used to define the communication specification between client and server; while the gRPC uses proto protocol, which affects efficiency in message data serialization and deserialization. The high performance and proxy service support based on ZeroC ICE selects ZeroC ICE as the bottom layer communication framework of the high performance network communication library (Channel SDK for short) in this embodiment.
Ice is the most stable, powerful, high-performance, cross-platform and multi-language-supporting old brand open source middleware in the RPC communication field, and is particularly suitable for the programming of multiple development languages on one platform in the current Internet field; the Ice describes the interface of the service through a neutral Language slice (specification Language from Ice) which is irrelevant to a programming Language, so that the aim of separating an object interface from the object interface is fulfilled; the proto protocol is not used as IDL of a client and a server to describe request parameters, response structure and message data serialization (influence communication efficiency) of the service and the method like gRPC, and the Http2 protocol is used by gRPC, and the coding and transmission mechanism efficiency is far lower than that of a Socket mode of long connection, so that the communication efficiency of Channel SDK is greatly improved by selecting zeroC ICE as a communication framework.
Moreover, as shown in fig. 1, the communication architecture of the ZeroC ICE includes an IceGrid service and a Glacier2 routing firewall, when a computation task is started, a service of each node process automatically allocates a port and starts snooping, binds an ip and a port of a server thereof to a specified AdapterId and a servatid and then registers the server to the IceGrid service, and the Glacier2 routing firewall finds a specified corresponding server from the IceGrid service through the specified AdapterId and the servatid and forwards a message. Wherein adapterId and servant Id are the data Adaptation ID and the servo object ID of the server, respectively.
Thus, each participant (node) starts the node process when the calculation task is started, the service of the node process automatically allocates a port and starts monitoring, then the process binds the ip and the port of the server on the appointed adapterId and servant Id and then registers the ip and the port on the IceGrid service, and the Glacer 2 routing firewall finds the appointed corresponding server from the IceGrid through the appointed adapterId and servant Id to forward the message; the node process is used as a stub object which is created by the client and connected with the proxy service of other node processes, and the client sends data to the opposite terminal through the stub object. Wherein each participant can be a client and/or a server; each participant binds the ip and port of its server on the specified AdapterId and servertid and then registers on the IceGrid service of the own-side ZeroC ICE architecture.
As shown in fig. 2, the network topology connection creating program includes: connecting the first high-performance network communication library of the first communication party P0 with the second Glaser 2 routing firewall of the second communication party P1, and connecting the second network communication library of the second communication party with the first Glaser 2 routing firewall of the first communication party, thereby establishing the network topology connection of the first communication party and the second communication party; the first communication party and the second communication party are any communication parties in the privacy computing network, namely any nodes in the privacy computing network, other communication parties in the privacy computing network adopt a network topology connection establishing program which is the same as the first communication party P0 and the second communication party P1 to carry out mutual pairwise connection, and after two or more communication parties participating in the computing task are connected pairwise in any computing task, a plurality of communication parties can establish a small-sized topology network.
The first communication party P0 and the second communication party P1 are both nodes in a distributed privacy computing network, and when participating in a computing task, the first communication party P0 and the second communication party P1 are clients or servers, and both the first communication party P0 and the second communication party P1 are internally provided with a Channel SDK and a ZeroC ICE architecture, so that the first high-performance network communication library of the first communication party P0 is connected with the second Glacier2 of the second communication party P1 through a firewall, and the second Glacier2 finds the corresponding ip and port of the second communication party P1 on the second IceGrid service, so that the message and data of the first communication party P0 can be forwarded to the second communication party P1; similarly, the second high-performance network communication library of the second communication party P1 is connected with the first Glacier2 routing firewall of the first communication party P0, and the first Glacier2 routing firewall finds the corresponding ip and port of the first communication party P0 on the first IceGrid service, so that the message and data of the second communication party P1 can be forwarded to the first communication party P0; therefore, after the network topology connection of all nodes is completed at home, the mutual transmission of messages and data among all the participants can be realized.
In addition, in the process of computing the task, the integrity of the data must be ensured, otherwise, the computing task cannot be successfully executed; each transmission of data must be guaranteed to be successful; as shown in fig. 3, the data retransmission procedure includes the following steps: step A1: the client sends data and a service request to the server, and the step A2: after receiving the sent data and the service request, the server processes the service request, stores the data and returns a response state 0 to the client; step A3: the client waits for a response, calculates the residual overtime time T of the periodic task, then judges whether the T is 0 or not, and if not, continuously judges whether the response state is 0 or not, if so, the transmission is successful. The periodic task time is set according to actual needs, and in step A3, when the response status is judged not to be 0, the system sleeps for a set time period T, and then returns to continue to execute step a1, wherein T < T. In this way, by supporting the functions of data retransmission, timeout and the like during abnormal conditions, the integrity of data and the robustness of a program are ensured.
In addition, as shown in fig. 4, the data reading and storing program includes: after each server receives data from the client, storing the data in a cache according to a preset cache rule; and each server side acquires data from the cache according to the requirement, and deletes the acquired data from the cache. The preset caching rule is that nodeid + msgid of a corresponding client is stored as a key word; and when the data is obtained from the cache, a Receive interface of the server side is called, and the nodeid + msgid is used as a key word key to obtain the data from the cache. Thus, each server may need to receive data sent by multiple clients or a single client for multiple times, and the server stores the data regularly, for example, nodeid + msgid as a key in a cache; the server side calls a Receive interface of the server side according to the requirement, and acquires data from the cache by taking the nodeid + msgid as a key; the retrieved data will be deleted from the cache. The node ID and the msgid are two IDs of the client, wherein the node ID is a node identifier, and the msgid is a communication type identifier; therefore, a plurality of clients can be supported to simultaneously send data to one server, and after the rpc interface of the server responds, the data is cached, and the data in the cache is read according to the requirement; the user only needs to realize data transmission and access as conveniently as a function adjusting function.
In addition, the data retransmission program is a mode of creating a zeroC ICE stub object, long connection between the client and the server is saved, and the functions of efficient communication between the client and the server and automatic recovery after abnormal disconnection of a network are realized.
And the data reading and storing program uses the combination of the Hash Map and the Queue container to store the data, so that the receiving sequence of the data can be ensured, and the efficient storage and reading of the data can be realized.
In addition, the high-performance network communication library of the embodiment is set as a pluggable component, so that the high-performance network communication library can be directly used in a node process in a pluggable mode, and is very convenient to install and use.
The high-performance network communication library is packaged on a zeroC ICE frame, a network topology is established through configuration, data in a communication process are stored, and the data are taken out when the high-performance network communication library is used; in addition, the proxy service in the zeroC ICE framework is combined and used in a component form, and under the existing framework, a user can realize the proxy service only by adding a combined code; the Channel SDK well solves the problem, supports a plurality of clients to send data to one server at the same time, caches the data after the rpc interface of the server responds, and reads the data in the cache according to the requirement; the Channel SDK is used only by configuring information such as IP and Port of Glacier2 and IceGrid, and the like, and the code is not required to be modified, so that a user can use the proxy service without deeply knowing the principle of the Glacer 2 and the IceGrid.
The high-performance network communication library of this embodiment implements point-to-point high-performance communication by means of a stable and efficient rpc framework, and in the whole communication process, it is necessary to ensure the integrity, security and network robustness of data and implement an efficient caching mechanism for data. Where ZeroC ICE uses a compact, efficient binary protocol (gRPC uses proto protocol, affecting efficiency in message data serialization and deserialization) to minimize CPU and bandwidth consumption, and IDL Slice of ICE is used to define the communication specification between the client and the server.
The high-performance network communication library of the embodiment is properly expanded and can be used in any scene of point-to-point high-performance communication; moreover, the network communication service is widely used in the IT industry, and by using the Channel SDK of the high-performance network communication library, a programmer can realize high-performance network communication without concerning the problems of loss, disconnection and the like of sending data in a multi-concurrency and complex network environment.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
