Ettev\u00f5te Nokia esitles<\/a><\/noindex> uus v\u00f5rguhalduss\u00fcsteem Service Router Linux<\/a><\/noindex> (SR Linux), mis on suunatud<\/a><\/noindex> mille eesm\u00e4rk on kasutada andmekeskuste ja pilveteenuste v\u00f5rgustruktuuris. SR Linuxi k\u00e4sitletakse Nokia Data Center Fabric lahenduste v\u00f5tmeelemendina ning seda paigaldatakse Nokia 7250 IXR ja 7220 IXR marsruutidesse. SR Linuxi p\u00f5hine lahendus on juba testimisel Apple'i uues Taani andmekeskuses.<\/p>\n

Erinevalt teistest Linuxi tuumal p\u00f5hinevatest v\u00f5rguseadmestest v\u00f5imaldab SR Linux juurdep\u00e4\u00e4su alusplatformi Linuxi keskkonnale, mis ei ole peidetud spetsialiseeritud API-de ja liideste taha. Kasutajatel on juurdep\u00e4\u00e4s muutmata Linuxi tuumele ja p\u00f5hiosa rakendustele (bash, cron, Python jne), samas kui spetsiifilised rakendused luuakse NetOps Toolkit'i t\u00f6\u00f6riistade abil, mis ei ole seotud kindlate programmeerimiskeeltega. NetOps Toolkit'i p\u00f5hjal loodud rakendused, n\u00e4iteks marsruutimisprotokollide rakendused, p\u00e4\u00e4sevad ligi erinevatele v\u00f5rgule API-dele, kuid toimivad iseseisvate komponentidena. <\/p>\n

Selline l\u00e4henemine v\u00f5imaldab hallata rakendusi eraldi operatsioonis\u00fcsteemist, n\u00e4iteks saab rakendust uuendada ilma s\u00fcsteemi muutmata v\u00f5i operatsioonis\u00fcsteemi uuendada ilma rakendusi uuesti koostamata. Lisaks vaikimisi rakendustele, nagu marsruutimisprotokollide rakendused, on lubatud k\u00e4ivitada ka kolmandate osade programme. Muutmata Linuxi tuuma kasutamine lihtsustab oluliselt haavatavusi parandavaid plaastrite haldamist ja t\u00e4ienduste loomist. Lubatud on juurdep\u00e4\u00e4s Linuxi utiliitidele, plaastritele ja pakettidele, samuti toetatakse isolatsioonikonteinerites k\u00e4ivitamist.
\nToetatakse kontrollpunktide m\u00e4\u00e4ramist muudatuste tagasikutsumiseks v\u00f5imalike probleemide korral.<\/p>\n

\"Nokia<\/center><\/p>\n

Haldamine v\u00f5ib toimuda l\u00e4bi gNMI<\/a><\/noindex> (gRPC Network Management Interface), k\u00e4surealiidese, Python'i pistikute ja JSON-RPC p\u00f5histe API-de kaudu.
\nTeenuseid, mis toimivad s\u00fcsteemis, on soovitatav kasutada gRPC ja andmevahetuse protokolli Protocol Buffers. SR Linuxi rakendused saavad vahetada olekuteavet, kasutades «publish\/subscribe» (pub\/sub) arhitektuuri, kus kasutatakse samuti gRPC ja Protocol Buffers, ning tagatud kohaletoimetamise mehhanismina kasutatakse IDB (Nokia Impart Database).
\nRakenduse oleku ja kasutatava konfiguratsiooni teabe struktureerimiseks kasutatakse YANG (Yet Another Next Generation) andmemudeleid, RFC-6020<\/a><\/noindex>). <\/p>\n

V\u00f5rguprotokollide teostused, sealhulgas Multiprotocol Border Gateway Protocol (MP-BGP), Ethernet VPN (EVPN) ja Virtual Extensible LAN (VXLAN), p\u00f5hinevad t\u00f5estatud SR OS (Nokia Service Router Operating System) protokollide virnal, mida on juba rakendatud enam kui miljonis Nokia ruuteris. Riistvaralistest komponentidest eemal hoidmiseks kasutatakse alams\u00fcsteemi XDP<\/a><\/noindex> (eXtensible Data Path).<\/p>\n

Andmekeskuse v\u00f5rgu infrastruktuuri loomise, juurutamise, seadistamise operatsioonide automatiseerimiseks, samuti telemeetriate kogumiseks ja anal\u00fc\u00fcsimiseks pakutakse Nokia Fabric Services Platformi (FSP). FSP annab ka t\u00f6\u00f6riistad v\u00f5rgu simuleerimiseks, et lihtsustada v\u00f5rgu planeerimist, projekteerimist, testimist ja t\u00f5rkeotsingut. V\u00f5rgu komponente simuleeritakse konteinerite isolatsiooni abil Kubernetes platvormi baasil, mis v\u00f5imaldab k\u00e4itada eraldiseisvaid SR Linuxi koopiaid isoleeritud keskkondades.<\/p>\n

FSP v\u00f5imaldab sisuliselt tarkvara kaudu luua virtuaalse koopia reaalsetest v\u00f5rgust ja kasutada selles simuleeritud v\u00f5rgus sama tarkvara (SR Linux konteinerites), mis on kasutusel t\u00f5elistes ruuterites ja l\u00fclitites. Veelgi enam, reaalses ja simuleeritud v\u00f5rgus kasutatakse \u00fchte ja sama konfiguratsiooni, mis v\u00f5imaldab kasutada tarkvara simuleeritud v\u00f5rku esimesena muudatuste sisestamiseks ja testimiseks. Simuleeritud keskkonna p\u00f5hjal v\u00f5ib FSP genereerida kogu teabe, mis on vajalik reaalse v\u00f5rgu juurutamiseks. <\/p>\n
