9 Feedback Mechanisms:
• Congestion control often relies on feedback from routers, switches, and endpoints to adjust transmission
rates and routing decisions.
10 Network Monitoring and Measurement:
• Monitoring tools continuously assess network performance and congestion levels. This data is crucial for
making informed decisions about congestion control strategies.

Congestion control is a complicated and ongoing challenge in network engineering.
Effective congestion control mechanisms ensure that networks can handle varying levels of traffic while providing
a consistent, reliable experience for users and applications.
TELNET
Telnet (Telecommunication Network) is a protocol used for remotely accessing and managing devices over a
network, typically the internet. It allows a user to establish a text-based connection to a remote server or device
and interact with it as if they were directly connected to the device’s console
Telnet operates on the Application Layer of the OSI model and uses a client-server architecture.
The client application (telnet client) initiates a connection to the remote server (telnet server) using the Telnet
protocol. Once the connection is established, the user can send text commands to the server and receive text-
based responses.
Telnet sessions are typically used for tasks such as remote administration, configuration, and troubleshooting of
devices such as routers, switches, servers, and other network equipment.
Advantages of Telnet
It provides remote access to one’s computer system.

Telnet allows the user to have more access with less problems in data transmission.
telnet saves a lot of time.
The oldest system can be connected to a newer system with different operating systems with telnet.
Disadvantages of Telnet

• As it is somewhat complex, it becomes difficult for beginners to understand.
• Some capabilities are disabled because of not proper interlinking of the remote and local devices.
• Data is sent here in plain text form, that’s why it is not so secure.
