In this assignment you will continue to hone your distributed systems development skills. You will implement a distributed consensus protocol and use it as a building block for a distributed application.AssignmentYour task is to implement the Raftdistributed consensus protocol and then use it to implement a distributed version of Rock ‘Em Sock ‘Em robots.Note that although there are many Raft implementation available on the internet, you will need to implement yours from scratch undue similarity to publicly available code will be seen as plagiarism.Rock ‘Em Sock ‘Em RobotsFrom Wikipedia we learn: “Rock Em Sock Em Robots is a two-player action toy and game. It features two dueling robot boxers, Red Rocker and Blue Bomber, mechanically manipulated by the players, and the game is won when one player knocks the head off of the opponent.” You can see a lifesize version the game in action here!Your distributed program should allow human players on two different computers as either Red Rocker and Blue Bomber. Each robot can be directed to perform the following actions (slightly modified from the original game):●punch_with_left()[Q]●punch_with_right()[W]●block_with_left()[A]●block_with_right()[S]When a robot blocks, it enters a blocking_with_left,or blocking_with_rightstate, which persists until another action is taken. When blocking_with_leftopponent’s punches with the right are blocked. Analogously for blocking_with_right,punches with opponent’s left are blocked.When punching an opponent who is not blocking, a robot has 10% chance of landing a hit. If a hit lands, the opponent’s head is knocked off and the the match is over. A robot can only punch once a second. After being blocked, a robot cannot punch for three seconds with either hand.One of your tasks will be to define a user interface that lets a user take actions and receive feedback as to its effect. Because your system includes two players, you may need to write scripts that trigger their actions. RaftYou will host your game on using two clients and five servers. We will assume that clients do not fail, but the servers and communication between them can. The role of the servers is to maintain game state and arbiter the order of player actions.The five servers will run the Raft consensus protocol to maintain between them log of player actions. To implement the game, the servers will also need to use this log to maintain game state, specifically whether a player is currently blocking and whether they are allowed yet to dispatch another punch.In addition to normal Raft operation, your servers need support the following operations:●fail()-the server ‘crashes’ and loses all local state●recover()-the server ‘recovers,’ rejoins the Raft protocol, and recovers the log and state●timeout()-the server decides that it has not heard from the coordinator within a timeoutYou will use these operation to demonstrate the robustness of your Raft implementation.DeploymentYou must implement a system with five server nodes. Each node will be run on a different machine. The log should be written to permanent storage, so that it will survive node crashes. You need to provide, at least, a minimal user interface (UI) for players to take actions. A text-based UI is fine. The contents of the log must also be viewable, for example by reading a file, so long as the file is human readable.You will deploy your project on Amazon EC2, on five machines in different regions. You will use micro-instances. You should sign up for AWS Educate to get your $35 credit for use of Amazon’s cloud infrastructure. This should be enough for you to deploy and demo the project. You should not do your development in AWS, but push your code from a repository (GitHub, BitBucket) to your AWS instances to test and demo. Please be careful to use a private repository, or otherwise protect private keys so that your AWS accounts are not hacked.GradingYour grade will be based on a screencast that demonstrates the functionality of your code. I expect the demonstration to show the different types of events that players may take. You also need to demonstrate the correct operation of your Raft implementation through server crashes and timeouts. I will be looking for functionality and correctness of your mechanisms.What to submit? 1.A link to a YouTube video showing your code running on AWS instances.2.Your source code (unzipped) for D2L plagiarism check代写CS Finance|建模|代码|系统|报告|考试编程类：C++,JAVA ,数据库,WEB,Linux,Nodejs,JSP,Html,Prolog,Python,Haskell,hadoop算法,系统 机器学习金融类：统计，计量，风险投资，金融工程，R语言，Python语言，Matlab，建立模型，数据分析，数据处理服务类：Lab/Assignment/Project/Course/Qzui/Midterm/Final/Exam/Test帮助代写代考辅导E-mail:[email protected]微信：BadGeniuscs 工作时间：无休息工作日-早上8点到凌晨3点如果您用的手机请先保存二维码到手机里面，识别图中二维码。如果用电脑，直接掏出手机果断扫描。
