What is an Aggregator?
An aggregator is any device that serves multiple other devices or users either with its own capabilities or by forwarding transmissions in a more concentrated and economical way.
Also, aggregators provide connectivity between carrier networks and mobile service providers. A content aggregator uses the Internet as the distribution medium. Most content aggregators are Web aggregators. It is a web-based and installed application that aggregates related (frequently updated) content, from various Internet sources and consolidates it in one place for viewing.
A typical aggregator or remote access hub is a device that handles incoming dial-up calls for an Internet (or other network) POP and performs other services. An aggregator may be able to handle up to 100 dial-up modem calls, support a certain number of Integrated Services Digital Network connections, and support leased line and frame relay traffic while also functioning as a router.
