TRANSPORT LAYER The transport layer in computer networks is responsible for ensuring data packets are transmitted accurately and reliably between senders and receivers. They utilise two major protocols: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP ensures that not even a data packet (unit) is lost during transmission, and when it's lost, it's retransmitted. It is used in applications such as bank transfers, emails, and webpages where losing one packet is catastrophic. It is usually slower than UDP and requires acknowledgement from the receiver for data packets sent. The sequence number (Seq) and acknowledgement number (Ack) are used together in this protocol to confirm the receipt of bytes of data contained in transmitted segments. The Ack number states the next byte they expect to receive from the source. They possess a header of 10 fields and 20 bytes. UDP, also known as the best effort delivery protocol or connectionless protocol, is utilised in situations where packet loss can be ignored. It is generally faster, and lost packets are not retransmitted. It's application is best for video calls, voice calls (VOIP), and other real-time communication systems where delay is expected to be minimal. There are no acknowledgement sent on the receipt of data in this protocol. Blocks of information in this protocol are called datagrams. They possess a header of 4 fields and 8 bytes. The only similarity between the TCP and UDP headers is the source and destination port numbers. - Israel Sajini #Telecom #Telecommunication #Engineering #Computernetworks #networking #1G #2G #3G #4G #5G Cisco Cisco Networking Academy Huawei Huawei Technologies Canada Co., Ltd.
