I need answers for this scenario based questions.
Web-based news casting system that has a server ‘publish’ news. This news is sent via callbacks to clients that have ‘subscribed’ to the newsfeed. Clients are untrusted in that they communicate over the Internet and anybody is able to write a client and connect to the service.
1.A major problem with using normal synchronous calls to have the server make callbacks to the (untrusted) clients and explain why asynchronous and oneway calls do not suffer from this problem.
2.asynchronous and oneway , which model is more suitable to implement the newscasting callback? Justify
