There are many ways to forward traffic from one domain/website to another. The so-called URL redirection is commonly recommended. In contrast to parking a domain, a URL redirection is feasible only if the domain in question is hosted. What this means essentially is that you may still open any content if you have a direct link to it and you may set up e-mail addresses or subdomains and use them. This sort of function has many practical uses - if you choose to switch your domain, you may forward the traffic, but the e-mail messages with the old one shall still be active if you are communicating with clients or partners. In case you have two very similar websites and you need to rebuild one of them, you could forward the site visitors to the other website in order to prevent losing potential clients, while you'll still be able to access the administration area for the first Internet site and develop it.
