\item \textbf{Searching}. Video assets can be searched by keywords and the results must be ordered by their relevance. The search can be done in the whole set of videos or in a particular category.

-\textit{Internal authentication} is for users that applied for an account by the \textit{Registration} page. There are situations when the platform must be integrated with other services or sites. For example in our university we use P2P-Tube to share videos of technical presentations, courses or social events. We also have Moodle learning platform where students already have an account, so it was desired that users can authenticate on P2P-Tube we the same account credentials from Moodle. This has been achieved thorough LDAP which permits students to authenticate on both sites with the same user name and password, without requiring them to create an additional account. Another way to make users skip signing up is by using OpenID, a standard protocol which allows them to sign in through an account from another site. However, this third party site must support OpenID. So, for example, users that already have an account on Yahoo!, Google, Twitter or WordPress can securely sign in with the same user names and passwords from that accounts. When users log in for the first time using external authentication, like LDAP or OpenID, they must complete their profile.

Users can upload video assets through an upload mechanism described in the next subsection.
An user uploads a video file, referred here as \textit{raw video file}, to a web server and may also provide additional information about it, like title, description, tags etc.. When video upload is finished the process of content ingestion is started by the web server by sending a content ingestion request to a CIS. This is done directly, if the system has a single CIS, or indirectly via a CIS Load Balancer (CIS-LB), which forwards the request to one CIS from a pool of several CIS machines. By doing load balancing, the indirect request method provides scalability because more content ingestion jobs can run in parallel, allowing more users to add content simultaneously to the platform. By these means availability is also increased, the system becoming fault tolerant in case of CIS failures.
-Note that sending content ingestion request is transparent for the web server. There is no difference for it if this is done directly to a CIS or indirectly through a CIS-LB. This simplifies implementation of the web server and hides the abstraction of content ingestion from it.
