easy installation, cheap price and convenient maintenance, etc.. The initial investment is quite
large but the maintenance cost is cheaper.
6. Compared with other communication ways
VAST system possess the characteristic that communication link cost is not relevant to
the distance, thus it is particularly applied to remote areas.
7. VSAT system expansion is easier.
Use scope and transmission ability of VSAT can be expanded as long as the number of small
station is increased and the bandwidth of uplink carrier and downlink carrier is adjusted
according to the demand. The system’s expansion ability has much to do with equipment’s
model selection; therefore, it should have certain predictability for development prospect of the
system when designing the system.
Transmission Control Protocol (TCP)
The transmission control protocol (TCP) is the internet standard ensuring the successful
exchange of data packets between devices over a network. TCP is the underlying
communication protocol for a wide variety of applications, including web servers and
websites, email applications, FTP and peer-to-peer apps.
TCP operates with the internet protocol (IP) to specify how data is exchanged online. IP
is responsible for sending each packet to its destination, while TCP guarantees that
bytes are transmitted in the order in which they were sent with no errors or omissions.
Together, the two protocols are referred to as TCP/IP.
TCP Header Format
TCP segments are sent as internet datagrams. The Internet Protocol header carries several
information fields, including the source and destination host addresses [2]. A TCP header
follows the internet header, supplying information specific to the TCP protocol. This division
allows for the existence of host level protocols other than TCP.](https://image.slidesharecdn.com/vsatincomputernetwork-210531170951/85/Vsat-in-computer-network-3-320.jpg)

- 1. Assignment: Assignment name : vsat in computer network Course code: CSE 318 Submitted to: pranab Bandhu nath senior Lecturer, Department of CSE City university, Dhaka Submitted by Md parvez Id: 184902610 Bsc in cse(day) Batch :49th what is vsat in computer networking A very small aperture terminal (VSAT) is a small-sized earth station used in the transmit/receive of data, voice and video signals over a satellite communication network, excluding broadcast television. ... The satellite sends and receives signals from a ground station computer that acts as a hub for the system. VSAT System Features 1 It possesses the ability of digital treatment and transmission for multiple signals including voice, data and television conference 2. Flexible multi-access mode. 3. Network management system is more and more perfect. 4. Abundant network topological structure. 5. VSAT device becomes gradually miniaturization and integration 6.

It possesses the ability of digital treatment and transmission for multiple signals including voice, data and television conference When transmitting voice, data and television conference, data compression technology has been widely adopted. 2. Flexible multi-access mode. The transmission line from primary station to remote small station is called outbound or outroute while the transmission link from small station to primary station is called inbound or inroute. The outbound information flow is discontinuous and the inbound information flow is intermittent, both of business volumes are asymmetric. Therefore, VSAT system adopts different multi-access continuation mode respectively in two transmission directions to realize asymmetric bidirectional transmission, which is the main difference between VSAT and other satellite communication system. 3. Network management system is more and more perfect. Because the information of small station is burst information, VSAT system must configure high intelligent network management system to monitor, control and manage operation status, channel allocation, business volume statistics of the overall network, which is one of the differences between VSAT and other satellite communication system. 4. Abundant network topological structure. Network topological structure of VSAT has three kinds which are star-shaped, meshed and composite. Star-shaped structure mainly applied in data communication must have primary station. Meshed structure mainly applied in voice communication doesn’t have primary station. And composite structure with more complex network management and channel control is available for large website comprehensively transferring multiple sets of information. The selection of network topological structure is mainly based on business demand
