Ephemeral port The allocations are temporary and only valid for the duration of the communication session. After completion of the communication session, the ports become available for reuse.[note 1] Since the ports are used on a per request basis they are also called dynamic ports. IPv6 Internet Protocol version 6 (IPv6) is the latest version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4, which still carries the vast majority of Internet traffic as of 2013. As of February 2014[update], the percentage of users reaching Google services over IPv6 surpassed 3% for the first time. Every device on the Internet is assigned an IP address for identification and location definition. With the ever-increasing number of new devices being connected to the Internet, the need arose for more addresses than the IPv4 address space has available. Technical overview

Round-trip delay time In telecommunications, the round-trip delay time (RTD) or round-trip time (RTT) is the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received. This time delay therefore consists of the propagation times between the two points of a signal. In the context of computer networks, the signal is generally a data packet, and the RTT is also known as the ping time. An internet user can determine the RTT by using the ping command.In space technology, the round-trip delay time or round trip light time is the time light (and hence any signal) takes to go to a space probe and return. The RTT was originally estimated in TCP by:
Internet Protocol Suite The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP, because its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination.
Wireless network Wireless icon. A wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks. Atomic Design We’re not designing pages, we’re designing systems of components.—Stephen Hay As the craft of Web design continues to evolve, we’re recognizing the need to develop thoughtful design systems, rather than creating simple collections of web pages. A lot has been said about creating design systems, and much of it focuses on establishing foundations for color, typography, grids, texture and the like. This type of thinking is certainly important, but I’m slightly less interested in these aspects of design because ultimately they are and will always be subjective. Lately I’ve been more interested in what our interfaces are comprised of and how we can construct design systems in a more methodical way.
