아주 옛날에는 통신사사업자 기술(PSTN, TDM/SONET/SDH, ATM, Router)과 Enterprise 기술(LAN - Ethernet L2/L3)이 명확히 구분되었었다. ATM과 Ethernet (Ethernet 승) (Enterprise -> 통신사) 90년대 후반에 45Mbps T3 ATM 랜카드는 200만원이었고 100Mbps 이더넷 랜카드는 몇 만원이었다. 또한 ATM 스위치와 이더넷 스위치의 가격도 이에 준했다. 경쟁 기술 중 승자는 에코시스템의 풍부함과 기계 가격이라는 것을 각인시켜준 사례이다. ATM은 사라졌고 통신사와 기업, 홈 시장에서 세상은 이더넷이 접수했다. SDN (Enterprise -> 통신사) SDN은 기업 데이터 센터내 트래픽...

지난 2월 평창동계올림픽에서 5G 네트워크 운영과 5G 시범 서비스를 성공적으로 선보인 KT가 3월 22일, 내년 3월 세계최초 5G 서비스 상용화를 공식 선언했다. 3GPP 5G 표준*이 제정되고, 올해 하반기 5G 기기 출시를 시작으로 내년 상반기 5G 스마트폰 출시가 예정되면서 5G 상용화를 향한 통신사간 경쟁이 한층 가열되고 있다. 또한 사용자들도 평창올림픽에서 선보인 타임 슬라이스 (Time Slice), 싱크뷰 (Sync View)와 같은 5G 실감형 서비스를 통해 기존과는 다른 생생한 경기를 체험하면서, 5G가 현실로 다가왔음을 느끼는 중이다. * 3GPP 5G 1차 표준 (Phase 1)인 Release 15 규격은 5G가 LTE와 연동하여 동작하는 NSA (Non...

Software-Defined Wide Area Network (SD-WAN), as a killer application featuring SDN and NFV, is now attracting much attention. In fact, it was not just another promising future technology, but has already been adopted in many commercial networks around the world. Globally (especially in the USA), the past two years have witnessed many enterprises migrating from conventional operator-pr...

한국 이동통신 3사가 모두 5G 도입을 준비하고 있는 가운데, 2G, 3G, LTE, LTE-A, 4.5G, IoT (LTE-M, LoRa, NB-IoT), WiFi 네트워크 등 통신사 네트워크는 갈수록 복잡해지고 그 성능이 고도화되고 있다. 동영상 이용증가로 계속되는 트래픽 증가와 곧 다가올 5G향 고용량 콘텐츠 등장으로 예상되는 트래픽 폭증은 네트워크 용량 증가와 스몰 기지국/셀의 확산을 요구한다. 또한 이통3사 모두 신성장 동력으로 IoT와 인공지능 (AI)를 강화하면서, 데이터를 분석하고 이를 활용하여 새로운 융합 서비스를 창출하는 빅데이터 비지니스와 분석된 데이터를 학습하여 맞춤형 서비스를 제공하는 AI 비지니스가 부상하고 있다. 스몰 셀 증가와 IoT, AI 서비스 확산에 대비...
