What is the TCP Reno algorithm?
TCP doesn't immediately acknowledge every single received TCP segment. If a single segment is received it is necessary to wait for 100-200ms on the assumption that the receiving application will probably generate a response of some kind. But if there is delay in sending acknowledgement by the receiver then the network is delayed.
Write the reasons for network delay in TCP algorithm?
The network delay is caused by "handshaking" or the connection-based protocol. This requires an answer (acknowledge) from every transmitted packet. Because the sender must wait for an answer before sending the next packet there will be a delay. The receiver has to indicate that the message was received correctly. In addition, if the packet is not received correctly then the sender must transmit it again. All of these can lead to delays.
What is the sub protocol that enables tcp ip to internetwork?
Both TCP and IP are subprotocols in the OSI model. IP is used for routing purposes, whereas TCP is used for transport control. If you are asking primarily about internetworking then it would be the IP protocol.
A tcp connection is in 'established' state.................?
It is established after the 3-way handshake is complete and the channel is open between a sender and a receiver.
The function of the checksum field in a TCP header?
The checksum field in a TCP header is used to verify the integrity of the TCP segment during transmission. It checks for errors that may have occurred in the data, ensuring that the segment received is the same as the one sent. The checksum is calculated over the TCP header and the data payload, and the receiver recalculates the checksum to confirm its accuracy. If the checksums do not match, the segment is considered corrupted and is typically discarded.
What are two ways that TCP uses the sequence numbers in a segment (Choose two.)?
TCP uses sequence numbers to ensure reliable data transmission by enabling the receiver to reassemble segments in the correct order, even if they arrive out of sequence. Additionally, sequence numbers allow the receiver to acknowledge the receipt of data, helping to manage flow control and ensure that lost segments can be retransmitted.
What is Tcp time stamp?
TCP timestamp is an option in the Transmission Control Protocol that allows for the inclusion of a timestamp in TCP segments. This feature helps in measuring round-trip time (RTT) and managing the sequence of packets more effectively, enhancing the efficiency of data transmission. By providing the sender and receiver with the ability to track the timing of packets, TCP timestamps can also help prevent issues like sequence number wraparound in long-lived connections. Overall, it improves the performance and reliability of TCP connections.
Why you use both TCP and IP protocols in computer networking?
TCP and IP protocols are used for different things. They were developed together and designed to be used together. IP is used for routing purposes. TCP is used for guaranteed reliable delivery (transport). They need each other to get packets from one place to another in a reliable fashion.
What is a TCP sliding window?
A TCP sliding window is a flow control mechanism used in the Transmission Control Protocol (TCP) to manage the amount of data that can be sent before needing an acknowledgment from the receiver. It allows the sender to transmit multiple segments of data before requiring an acknowledgment, thus improving throughput and efficiency. The "window" refers to the range of sequence numbers that the sender can send without receiving an acknowledgment, and it can dynamically adjust based on network conditions and the receiver's buffer capacity. This approach helps to optimize data transmission and prevent network congestion.
What is exceptional acknowledgement?
TCP uses the acknowledgement number in segments sent back to the source to indicate the next byte in this session that the receiver expects to receive. This is called expectational acknowledgement.
Does Directv and Dish Network use TCP IP?
My Dish Network receiver is connected to my home LAN and the internet via TCP/IP for remote control of my DVR, on-demand movie downloads, etc. IIRC, there's a place in the Dish OnLine menu to get the receiver to request an IPv4 address from a DHCP server. If there's no IP address, then there's no remote control, online movies, etc. I'd bet that DirecTV has a similar setup.
What is tcp server processes?
The process of a TCP server is to receive TCP connections and handling the data correctly. The letters TCP in TCP server stands for transmission control protocol.
