PSH: Indicates pushed data RST: It is used to reset a connection that has become confused due to reject an invalid segment or refuse 2. This value is typically set to 10 Hz. Managing the RTO Timer An implementation MUST manage the retransmission timer(s) in such a way that a segment is never retransmitted too early, i. Persistence timer • Addresses zero (0) window size advertisement • Sender will stop sending until ack received from destination TCP • If ack gets lost, destination TCP will Title: TCP: Connection and Timer Management 1 TCP Connection and Timer Management. 6 TCP Connection Management Modeling.

It describes the data structures used to track active connections, including source/destination addresses and port numbers. The timer task updates timers periodically. Physical layer: Fundamentals of signals, Concepts of analog and digital signals, Bandwidth, Data rate Vs Bandwidth, Transmission losses, Channel capacity, Digital transmission (Encoding Suitable for multicasting Used for management process such as SNMP Used for routing updating protocol : such as creating communication tables and setting timers. After each segment is sent, TCP starts a retransmission timer, if ACK arrives before timer expires, cancel timer.
