The basis of categorizing work is to classify the type of Internet traffic; this is done by putting common groups of applications into different categories, e.g., "normal" versus "malicious", or more complex definitions, e.g., the identification of specific applications or specific Transmission Control Protocol (TCP) implementations. Adapted from Logg et al.
File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content to file-hosting sites and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The websites that host the directory services sell advertising and do not host the files themselves.
Traffic classification describes the methods of classifying traffic by observing features passively in the traffic, and in line to particular classification goals. There might be some that only have a vulgar classification goal. For example, whether it is bulk transfer, peer to peer file sharing or transaction-orientated. Some others will set a finer-grained classification goal, for instance the exact number of application represented by the traffic. Traffic features included port number, application payload, temporal, packet size and the characteristic of the traffic. There are a vast range of methods to allocate Internet traffic including exact traffic, for instance port (computer networking) number, payload, heuristic or statistical machine learning.
Sites like Share-A-Sale and Amplifinity provide referral fees. Vendors set the referral fees they're willing to pay and for what services. When the transaction happens, you get paid by the company for introducing a new customer to them. uRefer also allows merchants to set up referral programs for introductions and meetings, in addition to any transactions made.
