What are differences between Circuit, Packet and MPLS switching? Switching is a process of determining of the logical path, how data would travel between sender and receiver. Three main methods, that are commonly used in modern networks are: circuit switching, packet switching, and multiprotocol label switching.
Circuit Switching
Main feature of the circuit switching, is the connection that is being established before any ...
TCP/IP is using some of the Application layer protocols in addition to Transport and Internet layer protocols. Those protocols are used for transforming user requests to network friendly format through the TCP or UDP with IP.
Telnet
It is protocol used for remote login through the TCP/IP. It is using port 23 for the connection and behavior on the remote machine is ...
What is DDNS (Dynamic DNS) and what it is used for? DNS is used for host location and can be used effectively for that purpose, when the IP is of the host is relatively constant (static). However, nowadays, due to impossibility to assign static IP for every device in the network, most users are using dynamic IP subscription from their network ...
Computer generated processes require unique address to send and receive information. Port numbers are used for that purpose.
Process socket is a combination of host IP and process port number. Easy example is the Telnet service that is using port 23 by default. Knowing host IP address (for example 12.34.45.56) the socket address can be created (12.34.45.56:23). Even though Telnet’s default ...
Private addresses are used for internal network of the company, organisation, or the household. Since they are used for internal network, private addresses can not be used for accessing the Internet. Public addresses, however, can and should be used by organisations for external connection to the Internet. The ranges of available internal IPs are shown in Table 1.
Table 1. IPs ...
Leasing - is the process of borrowing of an IP by the device, while it is connected to the network. When the client is connected to the network for the first time, the IP is obtained from the DHCP server. It can be used for specified period of time depending on DHCP server and client configuration. If the defined time ...
Assigning IP addresses to all the end devices in the network is the main task of the DHCP. So called DHCP server is assigning the IP addresses and terminating those when they are not required anymore. DHCP server stores and modifies information about IPs that already are in use, that will be available soon, and which are not allowed. In ...
This article is intended to show difference between IPv4 and IPv6. It introduces the list of new features that IPv6 is offering.
When you see IPv6 address it is easy to notice how differently it is written. While IPv4 is written in a form of four decimal numbers separated by a period, the IPv6 is having eight hexadecimal numbers separated by ...
The name for the TCP/IP protocol IGMP can stand either for Internet Group Management Protocol or Internet Group Multicast Protocol. It is used for sending exact same packets of data to multiple nodes. Unlike broadcasting, the group of recipients can be defined. Although most of data is sent on P2P basis in the network, IGMP is providing multicasting that uses ...
What is Subnet Mask, Types of Subnet Mask? Why you should care? Well, every device in the IPv4 network has its own subnet mask, that defines which subnet device it belongs to. Subnet mask is a 32-bit number that is being combined with device IP for identification of its subnetwork.
Subnet mask can be written either in binary (111111.111111.111111.000000) or decimal ...
