To get 100% efficiency, transmission time must be T t + 2T p instead of T t. This means sender must send the frames in waiting time too. This packet is also 40 bytes. The idea is same as pipelining in architectures. To get 100% efficiency, we must have- T t / (Tt + 2Tp) = 1. The transmission of 3 packets can look like this: How sliding window works. Sliding window is used by most connection oriented network protocol, among others, the Point-to-Point protocol (PPP) which many people use to establish their home PC as temporary Internet node via a phone-line connection to an existing node. tcp.

At the Transport Layer (equivalent to Layer 4 in the OSI model), two protocols exist: TCP (Transmission … Tt = D/B . Now, let us find the maximum number of frames that can be sent in time T t + 2T p. Sliding window is a technique for controlling transmitted data packets between two network computers where reliable and sequential delivery of data packets is required, such as when using the Data Link Layer (OSI model) or Transmission Control Protocol (TCP). Few Terminologies : Transmission Delay (Tt) – Time to transmit the packet from host to the outgoing link.

It allows the sender to transmit multiple packets before waiting for an acknowledgement. The sliding-window algorithm works as follows. Transmission Control Protocol (TCP) tutorial explaining sequence number, TCP port number, sliding window, 3-way handshake, transmission timeout and TCP header compression .

In a sliding window protocol, optimal sender window size = 1 + 2a. I understand how sliding window protocol makes the network reliable. The key feature of the sliding-window protocol is that it permits streamed communication. Enter your search terms Submit search form: Web: www.rhyshaden.com Earn on the Web: TCP. Khaled . Sliding windows is a method by which multiple packets of data can be affirmed with a single acknowledgment.

2. Introduction. Later, when the remote terminal has read the byte, TCP sends a window update, moving the window 1 byte to the right. TCP requires that all transmitted data be acknowledged by the receiving host.

Sliding Window Protocols

1.

Sliding Window protocol handles this efficiency issue by sending more than one packet at a time with a larger sequence numbers. But how can it control the flow of data? 32.9k 6 6 gold badges 58 58 silver badges 91 91 bronze badges. At the receiving side, TCP immediately sends a 40-byte acknowledgement (20 bytes of TCP header and 20 bytes of IP header).

Sliding windows, a technique also known as windowing, is used by the Internet's Transmission Control Protocol as a method of controlling the flow of packets between two computers or network hosts. asked Jan 27 '11 at 5:35. user68350 user68350. If B is the Bandwidth of the link and D is the Data Size to transmit. In fact, TCP also uses sliding window. 667 1 1 gold badge 6 6 silver badges 6 6 bronze badges. share | improve this question | follow | | | | edited Jan 27 '11 at 7:36.
