TCP vs UDP: What's the Difference?

Multicast communication can have single or multiple senders and receivers and thus, IGMP can be used in streaming videos, gaming or web conferencing tools. Like other network protocols, IGMP is used on network layer. These versions are backward compatible. Following are the versions of IGMP:. IGMPv1 : The version of IGMP communication protocol allows all the supporting hosts to join the multicast groups using membership request and include some basic features. But, host cannot leave the group on their own and have to wait for a timeout to leave the group. The message packet format in IGMPv

In the era of Computer and Mobile technologies, computer network technology is growing at a very fast speed and frequency. Billions of electronic devices and gadgets are operating to make this happen. These devices are designed and manufactured by different manufacturers. They may have been developed using different hardware and software resources. Due to this, they are unable to establish a connection and communicate with each other for sharing data and other information.

It helps you to create a virtual network when multiple computer networks are connected. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork. In this tutorial, you will learn: What is TCP? What is UDP? How TCP work?

It is used by network devices , including routers , to send error messages and operational information indicating success or failure when communicating with another IP address , for example, an error is indicated when a requested service is not available or that a host or router could not be reached. For example, every device such as an intermediate router forwarding an IP datagram first decrements the time to live TTL field in the IP header by one. If the resulting TTL is 0, the packet is discarded and an ICMP time exceeded in transit message is sent to the datagram's source address. Many commonly used network utilities are based on ICMP messages. The related ping utility is implemented using the ICMP echo request and echo reply messages.

In query messages, the data section carries extra information based on the type of the query. Page 5. Note. ICMP always reports error messages to the original.

Internet layer. Thanks, Helder i was a bit confused on this one i will set that to my mind. ICMP is a Layer3 protocol. Not sure who said it was Layer2. ARP, on the other hand, while I might be willing to say it's Layer 2.

This tutorial explains types of network protocols and their functions in details. Understanding these basic network protocols with functions will help you in managing network effectively. Learn how the most common types of network protocols works in computer network.

Internet Control Message Protocol (ICMP)

The cast term here signifies some data stream of packets is being transmitted to the recipient s from client s side over the communication channel that helps them to communicate. This type of information transfer is useful when there is a participation of single sender and single recipient. So, in short, you can term it as a one-to-one transmission.

    ICMP is abbreviation for Internet Control Management Protocol and IGMP is abbreviation for Internet Group Management Protocol. While ICMP uses unicast Routing for error detection and notification messages, IGMP is used by hosts to join and leave Multicast groups.
