frequencies satellite networks are able to provide broadband services requiring wider bandwidth than the current services at C or Ku-band. As a consequence‚ some of the new services gaining momentum include mobile services‚ private intranets and high data rate internet access carried over integrated satellite-fiber ATM networks. Several performance issues need to be addressed before a transport layer protocol‚ like TCP can satisfactorily work over satellite ATM for large delay-bandwidth networks. In this paper

But from the ingenuity of a partnership of companies that sought to find a reasonable (and soon profitable) solution to the proprietary incompatibility of emerging information system networks. Although the networking of our information systems has many different areas for study‚ this paper is about Ethernet. In it‚ I will discuss the basic components of an Ethernet connection. How they work and how they don’t. The Ethernet connection
