COMPUTER NETWORKING

Detailed explanation-1: -1 Answer. The explanation is: Choke packet is sent by a node to the source to inform it of congestion. Two choke packet techniques can be used for the operation called hop-by-hop choke packet and source choke packet.

Detailed explanation-2: -Choke packets are used for congestion and flow control over a network. The source node is addressed directly by the router, forcing it to decrease its sending rate . The source node acknowledges this by reducing the sending rate by some percentage.

Detailed explanation-3: -In general, we can divide congestion control mechanisms into two broad categories: open-loop congestion control (prevention) and closed-loop congestion control (removal) as shown in Figure 4.27. In open-loop congestion control, policies are applied to prevent congestion before it happens.

Detailed explanation-4: -Congestion control relates to the general problem of traffic management for packet switched networks. Congestion means a situation in which the number of transmission requests at a specific time exceeds the transmission capacity at a certain network point (called a bottleneck resource).
