In 1999, <strong>HTTP\/1.1<\/strong> attempted to optimize network bandwidth usage with \u201ckeep-alive\u201d connections to handle advancing hardware technology. This allowed clients to reuse <strong>Transmission Control Protocol (TCP)<\/strong> connections for multiple requests and save time with data transmission. Still, only one request could be resolved at once. Eventually, the average website needed better resource handling than HTTP\/1.1 could offer. The web started to use multiple, simultaneous TCP connections to a single node to compensate. This negated the original benefits of the \u201ckeep-alive\u201d concept.<\/p>\n\n\n\n<p>In 2015, <strong>HTTP\/2<\/strong> introduced <strong>HTTP streams<\/strong> which allow multiple exchanges within the same TCP connection simultaneously. Problem was, packet loss issues from a single request would result in packet loss in other requests transmitting at the same time. This results in <strong>head-of-line (HOL) blocking<\/strong>, a networking issue where a set of packets is halted by the absence of one packet at the transport layer. HTTP\/3 is the next attempt to rectify this problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what\">What are HTTP\/3 and QUIC?<\/h2>\n\n\n\n<p>The <strong>HTTP\/3 <\/strong>specification has been a work in progress by the <a href=\"https:\/\/ietf.org\/\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">Internet Engineering Task Force<\/a> (IETF) since 2018. Its features are similar to HTTP\/2. The main difference is that it will utilize the <strong>QUIC<\/strong> network protocol by Google on top of <strong>User Datagram Protocol (UDP)<\/strong>, not TCP.&nbsp;<\/p>\n\n\n\n<p>UDP is generally faster than TCP because there are no checks and balances ensuring all packets are received. This isn\u2019t an issue for activities that may be restricted or <em>throttled<\/em> by network performance issues:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.inmotionhosting.com\/blog\/what-can-you-do-with-linux-vps-hosting\/\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">Multimedia streaming<\/a><\/li><li>Watching videos on YouTube or Vimeo (HD, 4K, 5K, etc.)<\/li><li>Online multiplayer games<\/li><li><a href=\"https:\/\/www.inmotionhosting.com\/blog\/voip-system-on-dedicated-server\/\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">Voice over IP (VoIP) applications<\/a> including <a href=\"https:\/\/www.inmotionhosting.com\/blog\/best-zoom-alternatives-for-online-video-conferencing\/\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">Zoom and Jitsi<\/a><\/li><\/ul>\n\n\n\n<p class=\"alert alert-info\">College students and gamers, read about our recent Call of Duty tournament for <a href=\"https:\/\/www.inmotionhosting.com\/employment\/latest-news\/ecpi-scholarship-tournament-winners\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">ECPI University scholarships<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"quic\">What is QUIC?<\/h3>\n\n\n\n<p><strong>QUIC<\/strong> offers packet retransmission and other features similar to TCP for better reliability to complement the speed of UDP. But unlike HTTP\/2 streams, QUIC streams are separated to mitigate the effects of packet loss and HOL blocking. QUIC also uses TLS 1.3 for encryption and authentication. In summary:<\/p>\n\n\n\n<ol class=\"article_list wp-block-list\"><li>A QUIC connection is sent to a UDP port and IP address<\/li><li>An established connection is then associated with a connection ID<\/li><li>HTTP requests and responses are exchanged within that QUIC connection<\/li><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why\">Why is HTTP\/3 Important?<\/h2>\n\n\n\n<p>Supporting HTTP\/3, sometimes referred to as <em>H3<\/em>, shows a proactive effort to <a href=\"https:\/\/www.inmotionhosting.com\/blog\/ways-to-learn-more-about-cybersecurity\/\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">protect your cloud data<\/a> and offer the best possible user experience (UX) to online visitors and <a href=\"https:\/\/www.inmotionhosting.com\/blog\/keeping-your-ecommerce-website-secure-for-the-holidays\/\" target=\"_blank\" aria-label=\" (opens in a new tab)\" rel=\"noreferrer noopener\" class=\"rank-math-link\">eCommerce<\/a> customers.
