End to End

The challenges of using satellites in end-to-end talk theory links GEO satellite networks have the potential to furnish the end drug user the ability to receive air out and multicast in greater amounts of information at higher rate of speed providing global connectivity anywhere within the tone of the satellite. On the other hand there argon several(prenominal) challenges that are presented when utilizing satellite networks. These challenges are seen by the end user in several different formats the most common one being in profits applications.The reaction time experienced by the end user due to the communication between two acres stations cigaret be important and often annoying. A tremendous amount of military and government organizations apply and rely on satellite communications, when that path fails due to blocked areas, need of available bandwidth or atmospheric interference then this becomes a grievous situation and another reason why redundancy and a inessential and tertiary plan is always needed.Point to point fiber optic connections preempt provide a solid backup plan if availability is an option. The latency may not affect bulk data transfer and broadcast type applications, but those applications requiring extensive handshaking between two sites go forth be undoubtedly affected. TCP which is one of the Internets major protocols requires such interaction. Satellites that can provide the end user with global and broadband communications depicted object are also an option but also come with challenges of its own.LEO(low earth orbit) and MEO (medium earth orbit) each are a viable source that provide latency times comparable to that of a terrestrial fiber optics even because neither can remain in a constant placed position relative of that of the earth, a constellation of several satellites is required to find comprehensive coverage. In this case network management becomes increasingly more(prenominal) complicated due to handoff to an other satellite, tracking problems and proper routing plans. The advantage of a simple topology is no longer a factor and lose is single-source broadcast/multicast capability and brings you back to ground zero.
