海外TECH	DEV Community	HTTP/3. All you need to know	https://dev.to/vudodov/http3-all-you-need-to-know-bmk	HTTP All you need to knowHTTP is a long overdue change in the way the Internet works Surprisingly though it does not impact us as protocol consumers much Moreover the transition will be barely noticeable Eventually we will notice that port is gone And we won t need to type https anymore We will be getting back to http We ll talk more about it later ️Port is the one that is used for secure HTTP aka HTTPS connection So hmmm What is it all about It is all about TCP really Or should I say it s retirement TCP has been around for astonishing years It is obsolete by any even most conservative IT standards So it was decided to replace it with a more modern transport layer protocol QUIC ️HTTP is an application layer protocol that sits on top of the transport layer protocol like TCP HTTP uses QUIC instead of TCP QUIC is the main driver for the new version of HTTP And that s pretty much everything that changes from an HTTP perspective Semantics stays the same Hence all we know about HTTP as consumers stay the same It will only be riding new wheels Why to change it Why now It seems like internet is working fine isn t it SpeedConnection reliability is a given thanks to TCP Thus the ultimate connection measurement is its speed And obviously there s no way to sell a new protocol without improving it Three factors dramatically improve QUIC data transition speed compared to TCPReal Streams is actual direct data transition speed improvement Improved handshake is an improvement in connection establishment speed Connection Migration reduces the number of necessary re connections hence fewer connection establishments and data losses between sessions hence even more speed Real StreamsBecause in the TCP all packets are transitioned in a line if one packet is slow or lost the whole line has to wait for the slow lost packet to get back to its place and move on Even though TCP has a concept of streams those are not real streams but rather an abstraction to simulate them Multiple files are broken down into packets and packets are grouped in small frames but anyway go through a single stream in line QUIC implements streams I mean real streams so the data will flow truly simultaneously via a single connection but through multiple streams E g the JS bundle file might be a stream and markup another stream Apart from speed gain by truly parallelizing the packet transition there s an annoying problem that has been solved The Head Of Line Blocking You know when you are in a rush and get in the line at your grocery store And there s this super slow person in front that just slows the whole line down Well that s the HoL Blocking When a single slow object prevents other following objects from making progressAll versions of HTTP in one way or another suffered from the Head Of Line Blocking HoL on different levels In HTTP it was TCP HoL blocking because of a single stream nature QUIC doesn t really solve the HoL blocking problem it rather moves it to a different place Although it does not completely solve the problem nevertheless this shift significantly improves the performance The HoL Blocking can occur at the stream level Because stream order is still important you can t reorder or lose packets Hence if there s a slow fellow in the stream the stream can t proceed and have to wait But in this case it won t block other streams And once the issue with the annoying packet is solved the stream will resume HandshakeHandshake is a procedure of establishing a connection between client and server It ensures that both parties ready and know how to communicate TCP handshake is a necessary procedure occurring before any data can be sent over TCP It requires a client to send a request and receive a response acknowledgment from the server Time spent waiting is called round trip time RTT ️Nowadays we use HTTPS most of the time HTTPS is an HTTP over TLS Older versions of TLS and lower will require an extra handshake So in the worst case scenario there s another RTT on top of all other handshakes QUIC will require at least one handshake less It will require exactly one handshake for a new connection and no handshake for resumed connection Which makes QUIC RTT for a new connection and RTT for resumed Image is borrowed from SMB over QUIC Without the VPN by Ned PyleImage a shows required handshakes for a new connection As you could expect TCP with old TLS version will have RTT TCP with modern TLS RTT while QUIC only RTT Image b shows required handshakes for existing connection Once again TCP with old TLS will require RTT TCP with modern TLS RTT while QUIC RTTI vacuum completely identical circumstances the lesser handshakes the faster connection Connection MigrationThe way we use the Internet has significantly changed over the past decade Nowadays a large portion of the internet traffic is consumed while we are on the go Walking commuting on public transport or driving a car Imagine you live within mins walking distance from your work And you decide to enjoy a walk to work today There ll be at least guaranteed network changes on your way home wifi gt cell network G G gt work wifi However in reality during your walk while you are connected to a cell network you will be changing a network every minutes depending on the nearby cell tower range and how urban is the area you live work in On every new connection unavoidably at least one new handshake will be happening Any active data downloading uploading will be lost Your endpoints will think that connection just has been lost or terminated unexpectedly Have you ever experienced troubles with downloads uploads while you were on the go Well there you have it ️All large files nowadays downloaded and uploaded in segments so if the large file will be uploading or downloading you won t loose the whole file but rather a last segment TCP was not built nor was it optimized for such a usage ️The way TCP identifies a connection is pretty straightforward Each connection between two endpoints client and server is identified by parameters tuple Client IP address client port number server IP address and server port number If any one of the tuple changes TCP thinks it is a new connection And the old one will be lost it won t be even closed properly Every time the network changes the client will receive a new IP hence the whole connection tuple will be changed The Connection Identifier CID allows the QUIC server and client to identify that what they see is not a new connection but rather an existing connection migrated from another network Therefore no need for a handshake and the download upload process can keep on going ️It is a bit more involved process However there s one more aspect to it CID won t be encrypted However after every successful migration CID will be updated so the connection and your route won t be traceable by CID SecurityHTTP is a plain text protocol It simply sends a text over the wire or radio waves S in the HTTPS stands for Secure By using HTTPS we instruct a browser on a TLS protocol involvement in the communication TLS protocol will encrypt our data using advanced mathematical algorithms This ensures that even though the data might be intercepted by a third party it is useless Nowadays most web resources on the Internet use HTTPS Even though modern browsers insist on HTTPS usage we can still avoid it With QUIC it is unavoidable Because TLS is built in the QUIC Hence with HTTP there won t be a need for https and port Everything will be encrypted out of the box And there s no way to turn encryption off There s one small thing 🫠How do you go about upgrading the whole Internet All devices all routers everything that uses TCP And to give you a scale of the problem have you ever tried to trace any random request If not try with something like this online tracer and you will see how many nodes are involved in your request delivery These are middle boxes My google com trace shows middle boxes between me and the server And all of them use TCP And all of them probably don t run the latest version of Network Firmware When was the last time you updated your router firmware Exactly And this was the exact reason why a new protocol was required Because there s no way to update all devices in the world As you can tell simply adding a new protocol wouldn t work for the same reasons as updating TCP So what do you do The answer is User Datagram Protocol aka UDP It can provide a platform for the QUIC protocol It is broadly available and has been used as a base for many other protocols such as DHCP SMTP and RIP QUIC is built on top of UDP which makes it possible to deploy QUIC on the Internet scale Over of browsers support HTTP as I m writing this article It is only a matter of time before all browsers and the majority of modern app servers will switch to it CaveatsThere are a few things worth calling out QUIC protocol requires more processing power It has significantly improved since its first iterations Nevertheless compared to TCP QUIC will consume more resources And the other thing even though it is relatively easily deployable because it is built on top of UDP For the same reason initially companies will block it as it will open a backdoor of UDP Flood DDoS attacks Bottom LineHopefully this article builds a picture of what we can expect from HTTP and QUIC I m keen to see how the world will adopt the new protocol and what will be the future strategy for enabling it I reckon there are industries that might want to adopt it ASAP Gaming video streaming online communication meta to name a few I m glad that TCP is getting well deserved retirement I m still surprised at how long it worked on a global scale It set the bar high QUIC is already here As I mentioned majority of modern browsers support to a different extend HTTP hence QUIC I m waiting with anticipation to see if our hopes for a new internet evolution step will be justified	2022-06-22 11:39:53
