Po deseti letech monument\u00e1ln\u00ed pr\u00e1ce Peking ofici\u00e1ln\u011b spustil projekt \u010c\u00ednsk\u00e9 prost\u0159ed\u00ed pro s\u00ed\u0165ov\u00e9 inovace (CENI). P\u0159edstavte si rozlehlou s\u00ed\u0165 55 000 kilometr\u016f optick\u00fdch kabel\u016f propojuj\u00edc\u00edch 40 nejv\u011bt\u0161\u00edch m\u011bst v zemi. Nejde jen o p\u0159\u00edstup k internetu, jak ho zn\u00e1me, ale sp\u00ed\u0161e o laborato\u0159 pod \u0161ir\u00fdm nebem, platformu navr\u017eenou k vytvo\u0159en\u00ed s\u00ed\u0165ov\u00fdch technologi\u00ed z\u00edt\u0159ka, daleko vzd\u00e1len\u00fdch z\u00e1padn\u00edm standard\u016fm.<\/span><\/p>\n

S\u00ed\u0165 sou\u010dasn\u011b podporuje 128 heterogenn\u00edch s\u00edt\u00ed (architektury vz\u00e1jemn\u011b nekompatibiln\u00ed) a dok\u00e1\u017ee spustit 4096 paraleln\u00edch test\u016f. Pro v\u00fdzkumn\u00edky je to dar z nebes: ka\u017ed\u00fd si m\u016f\u017ee pohr\u00e1t se sv\u00fdm prototypem, ani\u017e by ru\u0161il sv\u00e9 sousedy.

\u010c\u00edsla mluv\u00ed sama za sebe. CENI p\u0159enesla 72 terabajt\u016f mezi radioteleskopem v Kuej-\u010dou a univerzitou v provincii Chu-pej (vzd\u00e1len\u00fdmi tis\u00edc kilometr\u016f) za pouh\u00fdch 1,6 hodiny. Tento objem p\u0159edstavuje p\u0159ibli\u017en\u011b 699 dn\u00ed p\u0159enosu dat v konven\u010dn\u00ed s\u00edti.

Ironii situace stoj\u00ed za zv\u00e1\u017een\u00ed. Peking snadno p\u0159irovn\u00e1v\u00e1 CENI k ARPANETU, p\u0159edch\u016fdci internetu spu\u0161t\u011bn\u00e9ho v roce 1969, a k GENI (Global Environment for Network Innovations), americk\u00e9 experiment\u00e1ln\u00ed s\u00edti. Oba tyto projekty v\u0161ak byly opu\u0161t\u011bny. GENI ukon\u010dil provoz 1. srpna 2023, po t\u00e9m\u011b\u0159 dvou desetilet\u00edch experimentov\u00e1n\u00ed.<\/span><\/p>\n

Trajektorie se radik\u00e1ln\u011b rozch\u00e1zej\u00ed. Ameri\u010dan\u00e9 postupn\u011b p\u0159enesli odpov\u011bdnost na soukrom\u00fd sektor. \u010c\u00edna d\u011bl\u00e1 opak: masivn\u011b investuje do ve\u0159ejn\u00e9 infrastruktury, aby otestovala standardy z\u00edt\u0159ka, pravd\u011bpodobn\u011b pokro\u010dil\u00e9 s\u00edt\u011b 5G a 6G. Za zm\u00ednku stoj\u00ed, \u017ee zem\u011b se ji\u017e py\u0161n\u00ed 3,4 miliony instalovan\u00fdch stanic 5G, co\u017e p\u0159edstavuje 60 % celosv\u011btov\u00e9ho po\u010dtu.<\/span><\/p>\n

Vedouc\u00ed t\u00fdm CENI vyvinul 206 technologick\u00fdch standard\u016f a z\u00edskal 221 patent\u016f. Peking se ji\u017e nespokoj\u00ed s pouh\u00fdm dovozem; buduje si vlastn\u00ed z\u00e1kladn\u00ed technologick\u00e9 stavebn\u00ed kameny. A zat\u00edmco Evropsk\u00e1 unie zva\u017euje svou digit\u00e1ln\u00ed suverenitu, \u010c\u00edna si ti\u0161e shroma\u017e\u010fuje trumfy na nadch\u00e1zej\u00edc\u00ed desetilet\u00ed.
