What is the Internet Control Message Protocol (ICMP)? The Internet Control Message Protocol (ICMP) is a network layer protocol used by network devices to diagnose network communication issues. ICMP is mainly used to determine whether or not data is reaching its intended destination in a timely manner. Commonly, the ICMP protocol is used on network devices, such as routers. ICMP is crucial for error reporting and testing, but it can also be used in distributed denial-of-service (DDoS) attacks. What is ICMP used for? The primary purpose of ICMP is for error reporting. When two devices connect over the Internet, the ICMP generates errors to share with the sending device in the event that any of the data did not get to its intended destination. For example, if a packet of data is too large for a router, the router will drop the packet and send an ICMP message back to the original source for the data. A secondary use of ICMP protocol is to perform network diagnostics; the...

What is Latency? Now a Days, Latency is a command word for all the users as whoever using internet. We only know about the good things related to the high speed of internet. In terms of Network latency means the network packet will take some times with request to travel from sender to receiver and from receiver to process the request. But in terms of simple words The Round trip time from one browser to the servers.  Network latency is used to indicate any kind of delay that happens in data communication over a network. Network connections in which small delays occur are called low-latency networks whereas network connections which suffers from long delays are called high-latency networks. High latency creates bottlenecks in any network communication. It prevents the data from taking full advantage of the network pipe and effectively decreases the communication bandwidth. The impact of latency on network bandwidth can be temporary or persistent based on t...

Layer 2 switch is one of the basic devices that you need. As the diversity of network applications increases and the implementation of converged networks grows. Layer 3 switch, are thriving in both data centers, complicated enterprise networks, commercial applications, and even advanced customer projects. Below is the brief discussion related to the Layer 2 vs Layer 3 Switch along with what are their differences? Details of Layers 2 and 3 Switches The Layers 2 and 3 are defined at Open System Interconnect (OSI) model, which is a reference model for describing and explaining network communications. The OSI model has seven layers and all are defined with my previous blog so go through for more discussion about that and among of that data link layer the Layer 2 and network layer is is the Layer 3. The switches working in these layers are called Layer 2 switch and Layer 3 switch respectively. The main difference between Layer 2 and Layer 3 is the routing function. Th...
