If the logical destination address of the packet is corrupted what will happen to the packet?
The receiver acknowledges packets it has received, and if the sender doesn't get an acknowledgment, it will eventually re-send the doubtful packet
Why is in stop-and-wait ARQ two Acknowledgements needed?
In stop-and-wait ARQ, two acknowledgements are needed to ensure that both the data packet and its acknowledgement are successfully transmitted and received. The sender waits for an acknowledgement after sending a data packet, and the receiver sends an acknowledgement to confirm the successful receipt of the data along with a request for the next packet. This two-step process helps regulate the flow of data between sender and receiver in a reliable manner.
In stop-and-wait ARQ why shoukld the receiver always send an acknowledgement message each time it receives a frame with a wrong number sequence?
When the receiver receives a good data packet, it sends an acknowledgement packet to the transmittor with a sexquence number of the NEXT packet it expects. That means, if the člast received data block has a sequence number 0, then the ACK contains sequence number 1, because the next block the receiver expects, ought to contain seq. number 1.
What is connection base internet protocol?
A connection based protocol requires a technique known as hand-shaking. This means that every packet that is transmitted requires a response from the receiver indicating that they received the packet and that the packet arrived safely. There is a 3-way startup sequence to create a connection using handshaking protocol.
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.
In protocol rdt3.0 the ACK packets flowing from the receiver to the sender do not have sequence numbers although they do have an ACK field that contains the sequence number of the packet they are?
To best answer this question consider why we needed sequence numbers in the first place. We saw that the sender needs sequence numbers so that the receiver can tell if a data packet is a duplicate of an already received data packet. In the case of ACKs, the sender does not need this info (i.e. a sequence number on an ACK) to tell detect a duplicate ACK. A duplicate ACK is obvious to the rdt3.0 receiver, since when it has received the original ACK it transitioned to the next state. The duplicate ACK is not the ACK that the sender needs and hence is ignored by the rdt3.0 sender.
What is a Minecraft packet?
A packet is a piece of data sent and received by servers and computers.
Which layer determines the route a packet takes from sender to sender to receiver?
Network Layer
What is Integrated Check Vector?
Integrated Check Vector (ICV) is a cryptographic checksum used in network communication to verify the integrity of data packets. It is appended at the end of a packet and is calculated based on the payload data using a specific algorithm. When a packet is received, the receiver calculates its own ICV and compares it to the one included in the packet to ensure that the data has not been altered during transmission.
What is an acknowledgement in networking?
In networking, an acknowledgment (ACK) is a signal sent from a receiver to a sender to confirm that a message or packet has been successfully received. This mechanism is crucial for ensuring reliable data transmission, as it allows the sender to know that the data has arrived intact and can proceed with sending subsequent packets. If an acknowledgment is not received within a specified timeframe, the sender may retransmit the data to ensure it reaches its destination. Acknowledgments are commonly used in protocols such as TCP (Transmission Control Protocol).
The address is used to identify the sender and receiver in an ip packet header?
That is called an IP address.
