Bursty traffic is converted to a uniform traffic by the leaky bucket. If there is a ready packet, a token is removed from the bucket, and the packet is sent. Network: The network layer is responsible for the packet (data chunks) routing. The Multiplicative Decrease part of the TCP congestion control divides the current value of the congestion window once congestion has been detected. Please use ide.geeksforgeeks.org, generate link and share the link here. Several techniques are used by different protocols; some of them are: In above diagram the 3rd node is congested and stops receiving packets as a result 2nd node may be get congested due to slowing down of the output data flow.

Choke packet technique is applicable to both virtual networks … In figure (A) we see a bucket holding three tokens, with five packets waiting to be transmitted. the number of packets sent to the network) is greater than the capacity of the network (i.e. Program to calculate the Round Trip Time (RTT), Introduction of MAC Address in Computer Network, Maximum Data Rate (channel capacity) for Noiseless and Noisy channels, Difference between Unicast, Broadcast and Multicast in Computer Network, Collision Domain and Broadcast Domain in Computer Network, Internet Protocol version 6 (IPv6) Header, Program to determine class, Network and Host ID of an IPv4 address, C Program to find IP Address, Subnet Mask & Default Gateway, Introduction of Variable Length Subnet Mask (VLSM), Types of Network Address Translation (NAT), Difference between Distance vector routing and Link State routing, Routing v/s Routed Protocols in Computer Network, Route Poisoning and Count to infinity problem in Routing, Open Shortest Path First (OSPF) Protocol fundamentals, Open Shortest Path First (OSPF) protocol States, Open shortest path first (OSPF) router roles and configuration, Root Bridge Election in Spanning Tree Protocol, Features of Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol (RIP) V1 & V2, Administrative Distance (AD) and Autonomous System (AS), Packet Switching and Delays in Computer Network, Differences between Virtual Circuits and Datagram Networks, Difference between Circuit Switching and Packet Switching.
