Web server software communicates with browser software No need to write software for network-core devices Network-core devices do not run user applications.. [Networks] 2주 2차 : Roadmap - Network Core Packet switching : 패킷 단위로 데이터가 쪼개져서 네트워크가 프로세싱 되는 방식 Store-and-forward : Entire packet must arrive at router before it can be transmitted on next link (Shared) Takes L/R seconds to transmit (push out) L-bit packet into link at R bps end-end delay = 2L/R (assuming zero propagation delay) Queuing and loss If arrival rate (in bits) to link exceeds transmission rate of link for a peri.. [Networks] 2주 1차 : Roadmap - What’s the Internet? Router : 내가 보낸 데이터의 경로를 알고리즘에 의해 결정 Internet Service Provider (ISP) : 네트워크를 구성해서 서비스 Host : End systems, 가장 말단에 연결되어 있음 Network app : 브라우저, 앱 등 네트워크에 연결되는 모든 Software Communication link Bandwidth : Transmission rate, bits per second Pocket switch : Routers & switches Node : 전체에 붙어있는 하나의 Entity Internet : Network of networks, interconnected ISPs Protocols : TCP, IP, HTTP, 8.. 이전 1 다음
