浏览器能否与Raw Socket通信？井字棋作业技术疑问

我们需要完成一个采用服务器-客户端架构的井字棋游戏作业，教授要求服务器使用层级低于TCP/UDP的Raw Socket实现，客户端为浏览器。这是否可行？

作业说明原本标注使用TCP/IP，但我询问教授后，她明确要求使用更底层的Raw Socket。以下是她提供的TCP服务器示例代码（禁止使用）：

# Import the required libraries
from socket import *

# Listening port for the server
serverPort = 12000

# Create the server socket object
serverSocket = socket(AF_INET,SOCK_STREAM)

# Bind the server socket to the port
serverSocket.bind(('',serverPort))

# Start listening for new connections
serverSocket.listen(1)


# For python 2.x use the following syntax for displaying strings:
print 'The server is ready to receive messages'

# For python 3.x use the following syntax for displaying strings:
#print('The server is ready to receive messages')


while 1:
        # Accept a connection from a client
    connectionSocket, addr = serverSocket.accept()

        ## Retrieve the message sent by the client

        # For python 2.x use the following (no need to convert from byte string to unicode):
        sentence = connectionSocket.recv(1024)

        # For python 3.x use the following
        # (explicit conversion from byte string to unicode using .encode() method):
    #sentence = connectionSocket.decode().recv(1024)
    
        #Modify the message
    capitalizedSentence = sentence.upper()

        ## Send the modified message back to the client
    
        # For python 2.x use the following (no need to convert from unicode to byte string):
        connectionSocket.send(capitalizedSentence)

        # For python 3.x use the following
        # (explicit conversion from unicode to byte string using .encode() method):
    #connectionSocket.send(capitalizedSentence.encode())

        # Close the connection
    connectionSocket.close()

教授要求我们实现比该示例更底层的服务器。我查阅资料后发现浏览器似乎无法与Raw Socket通信，但教授称已实现，对此我存在疑问。
