Question

What is the broadband communication system and how broadband network support quality of service (Qos)?

Answer 1

Broadband networks allow us to easily access multimedia services such as data, voice and video all in one package.It covers both standard and emerging broadband communication network systems. Internet-based networks, such as intranets and extranets. It then addresses the networking technologies of X.25 and frame relay, fiber channels, a synchronous optical network (SONET), a virtual private network (VPN), an integrated service digital network (ISDN), broadband ISDN (B-ISDN), and ATM. It also cover access networks, including digital subscriber lines (DSL), cable modems, and passive optical networks, as well as explore wireless networks, such as wireless data services, personal communications services (PCS), and satellite communications.
QoS necessary for voice and video streaming over the networkIt is also an important factor in supporting the growing Internet of Things (IoT)Some applications are sensitive to delay. These applications commonly use the UDP protocol as opposed to the TCP protocol. The difference between TCP and UDP as it relates to time sensitivity is that TCP will retransmit packets that are lost in transit while UDP does not. For a file transfer from one PC to the next.But for UDP applications such as an IP phone call, any lost packet cannot be retransmitted because the voice packets come in as an ordered stream; re-transmitting packets is useless. Because of this, any lost or delayed packets for applications running the UDP protocol are a real problem.
