I've been in this industry over 35 years and have lost count of how many times I have read articles like this speaking of "solutions" that are either just nonesense, old tech being rebranded or a mixture of both. Collisions, packet drops, suboptimal routing, deliberate traffic shaping, head of line blocking, contention and retransmits and latency will always be a thing. Every network and indeed server or even server clusters have limits. When those are hit performance is going to suffer. https://lnkd.in/emcuxWyu

Network Protocols Overview: Network protocols are standardized methods for transferring data between computers in a network. Here are eight popular network protocols Certainly! Here's the list of network protocols with index numbers: 1. HTTP (Hyper Text Transfer Protocol)   - Protocol for fetching resources like HTML documents.   - Foundation of data exchange on the Web.   - Operates in a client-server model. 2. HTTP/3   - The next major revision of HTTP.   - Utilizes QUIC, a new transport protocol.   - Relies on UDP for faster web page responsiveness.   - Ideal for VR applications needing high bandwidth. 3. HTTPS (Hyper Text Transfer Secure)   - An extension of HTTP.   - Ensures secure communication through encryption. 4. TCP (Transmission Control Protocol)   - Reliable, connection-oriented protocol.   - Guarantees data delivery in the correct order. 5. UDP (User Datagram Protocol)   - Connectionless and faster, but not reliable.   - Suitable for real-time applications like video streaming. 6. IP (Internet Protocol)   - Routes data packets across the network.   - IPv4 and IPv6 are two versions. 7. FTP (File Transfer Protocol)   - Used for transferring files over a network.   - Supports authentication and file management. 8. SMTP (Simple Mail Transfer Protocol)   - For sending emails between servers.   - Ensures reliable email delivery.

Does anyone remember HYPERchannel networks? It was a Network Systems Corporation technology 50 years or so ago. I touched so many network technologies over the decades but that was one of the more interesting ones. The FORE PowerHub (Ethernet/FDDI/ATM uplink) was an ok aggregator , though the FORE ATM switches were best of breed. Bay, Wellfleet, etc. so many network firms came and went. For the most part HP and Cisco rocked and I heavily leveraged their technologies. But now, I am looking to see what the next technology leap will be in the networking space, and how quickly we all embrace it. And will it be more secure? Just as long as I never have to solder RS-232 connectors to connect dumb terminals to Terminal servers - ever again. Or tap thick Ethernet in the ceiling of a building. https://lnkd.in/e5Jd5KgM

Networking protocols are the unseen pillars on which modern communication is built Understanding these protocols is essential for any IT professional, but navigating the vast landscape can be difficult. This post aims to demystify some of the most important protocols, laying the groundwork for further investigation. 𝟭. 𝗧𝗖𝗣/𝗜𝗣: The bedrock of the internet, TCP/IP operates in two key layers: TCP (Transmission Control Protocol): responsible for data reliability, ensuring packets arrive in the correct order and without errors. IP (Internet Protocol): manages routing, assigning unique addresses to devices, and directing data packets across networks. 𝟮. 𝗗𝗡𝗦 (𝗗𝗼𝗺𝗮𝗶𝗻 𝗡𝗮𝗺𝗲 𝗦𝘆𝘀𝘁𝗲𝗺): Think of DNS as the internet's address book. It translates user-friendly domain names (e.g., google.com) into numerical IP addresses that computers understand, enabling smooth communication. 𝟯. 𝗛𝗧𝗧𝗣 (𝗛𝘆𝗽𝗲𝗿𝘁𝗲𝘅𝘁 𝗧𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹): The driving force behind the web, HTTP governs how browsers and servers communicate. It defines request types (GET, POST), response codes (404, 500), and the format of web pages for seamless browsing. 𝟰. 𝗛𝗧𝗧𝗣𝗦 (𝗛𝘆𝗽𝗲𝗿𝘁𝗲𝘅𝘁 𝗧𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹 𝗦𝗲𝗰𝘂𝗿𝗲): HTTPS takes HTTP one step further, adding a layer of encryption for secure communication. This ensures data privacy and prevents eavesdropping, which is especially crucial for sensitive transactions. 𝟱. 𝗦𝗠𝗧𝗣 (𝗦𝗶𝗺𝗽𝗹𝗲 𝗠𝗮𝗶𝗹 𝗧𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹): The standard protocol for email delivery, SMTP manages the formatting, transmission, routing, and delivery of emails between servers over the internet. 𝟲. 𝗙𝗧𝗣 (𝗙𝗶𝗹𝗲 𝗧𝗿𝗮𝗻𝘀𝗳𝗲𝗿 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹): As the name suggests, FTP allows for transferring files between computers over networks. It facilitates both uploading and downloading files, making it essential for sharing data between clients and servers. 𝟳. 𝗨𝗗𝗣 (𝗨𝘀𝗲𝗿 𝗗𝗮𝘁𝗮𝗴𝗿𝗮𝗺 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹): Designed for speed and efficiency, UDP prioritizes fast transmission over complete reliability. This makes it ideal for time-sensitive applications like video streaming, online gaming, and voice chat, where even minor delays can be detrimental. Input is invaluable for helping refine this overview. #networking #protocols #programming #osimodel #pakistan #learningandgrowing #skillbuilding #skillup #structuralengineering

Secure Your Internet: VPN vs Proxy – Which One is Right for You?

Application Aware Routing is one of fundamental features of SD-WAN to keep optimal application performance. After speaking with several customers I have come to realize that it is not always 100% clear how it works, leading to missed optimization opportunities. I wrote the "Simplifying AAR" series to explain the fundamentals and go through some examples that will show exactly how things will work. Hope you find it useful! https://lnkd.in/gqXfJQ-g #sdwan #aar #cisco #netWithAlex

𝗞𝗲𝘆 𝗡𝗲𝘁𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹𝘀 Networking protocols serve as foundational pillars, enabling devices to interact on a network. For IT pros, understanding major protocols is non-negotiable, especially given the vast range today. Here's a concise breakdown of pivotal ones: 1. TCP/IP: The backbone of the internet. - TCP 📦: Manages data packet assembly & ensures delivery. - IP 🌍: Oversees addressing & packet routing, facilitating communication over networks. 2. DNS: Transforms domain names (e.g., google .com) into IP addresses 🌐 crucial for internet traffic routing. 3. HTTP: Governs web client-server interactions, dictating connection types, request methods, and response formats. 4. HTTPS: A secure extension of HTTP 🛡️, offering encryption and server authentication through SSL/TLS. 5. SMTP: The go-to for email 📧 transmission over the internet, overseeing email formatting & delivery. 6. FTP: Enables file transfers over TCP networks, streamlining exchanges between clients and servers. 7. UDP: Best for real-time actions like video streaming 🎥, online gaming, and voice communication. #systemdesign #coding #interviewtips #tcpip #tcp #ip #dns #http #https #ssl #tls #smtp #email #ftp #udp #webdev #coding #interviewtips #systemdesign #datatransmission #networking #securityprotocols #filetransfer #onlinestreaming #voip #internetprotocols

Network protocols/ Application protocols Network protocols are standard methods of transferring data between two computers in a network. 1. HTTP (HyperText Transfer Protocol) HTTP is a protocol for fetching resources such as HTML documents. It is the foundation of any data exchange on the Web and it is a client-server protocol. 2. HTTP/3 HTTP/3 is the next major revision of the HTTP. It runs on QUIC, a new transport protocol designed for mobile-heavy internet usage. It relies on UDP instead of TCP, which enables faster web page responsiveness. VR applications demand more bandwidth to render intricate details of a virtual scene and will likely benefit from migrating to HTTP/3 powered by QUIC. 3. HTTPS (HyperText Transfer Protocol Secure) HTTPS extends HTTP and uses encryption for secure communications. 4. WebSocket WebSocket is a protocol that provides full-duplex communications over TCP. Clients establish WebSockets to receive real-time updates from the back-end services. Unlike REST, which always “pulls” data, WebSocket enables data to be “pushed”. Applications, like online gaming, stock trading, and messaging apps leverage WebSocket for real-time communication. 5. TCP (Transmission Control Protocol) TCP is is designed to send packets across the internet and ensure the successful delivery of data and messages over networks. Many application-layer protocols build on top of TCP. 6. UDP (User Datagram Protocol) UDP sends packets directly to a target computer, without establishing a connection first. UDP is commonly used in time-sensitive communications where occasionally dropping packets is better than waiting. Voice and video traffic are often sent using this protocol. 7. SMTP (Simple Mail Transfer Protocol) SMTP is a standard protocol to transfer electronic mail from one user to another. 8. FTP (File Transfer Protocol) FTP is used to transfer computer files between client and server. It has separate connections for the control channel and data channel. #protools #networkengineer #cloudengineer
