Compania Nokia a prezentat<\/a><\/noindex> un nou sistem de operare pentru re\u021bea Service Router Linux<\/a><\/noindex> (SR Linux), orientat<\/a><\/noindex> pentru utilizarea \u00een infrastructura de re\u021bea a centrelor de date \u0219i a mediilor cloud. SR Linux este considerat a fi un component cheie al solu\u021biilor Nokia Data Center Fabric \u0219i va fi instalat pe routerele din seria Nokia 7250 IXR \u0219i 7220 IXR. Solu\u021bia bazat\u0103 pe SR Linux este deja \u00een testare \u00een noul centru de date din Danemarca, de\u021binut de Apple.<\/p>\n

Spre deosebire de alte sisteme de operare pentru echipamentele de re\u021bea bazate pe nucleul Linux, SR Linux p\u0103streaz\u0103 posibilitatea de acces la mediu, care st\u0103 la baza platformei Linux, care nu este ascuns sub API-uri \u0219i interfe\u021be specializate. Utilizatorii au acces la nucleul Linux nemodificat \u0219i la aplica\u021biile de baz\u0103 ale sistemului (bash, cron, Python, etc.), iar aplica\u021biile specifice sunt create folosind instrumentele NetOps Toolkit, care nu sunt legate de anumite limbaje de programare. Aplica\u021biile bazate pe NetOps Toolkit, cum ar fi implement\u0103rile protocoalelor de rutare, au acces la diferite API-uri de re\u021bea, dar func\u021bioneaz\u0103 ca module independente. <\/p>\n

Aceast\u0103 abordare ofer\u0103 posibilitatea de a gestiona aplica\u021biile separat de sistemul de operare, de exemplu, se poate actualiza aplica\u021bia f\u0103r\u0103 a aduce modific\u0103ri \u00een sistem sau se poate actualiza sistemul de operare f\u0103r\u0103 a recompila aplica\u021biile. Pe l\u00e2ng\u0103 aplica\u021biile standard, cum ar fi implement\u0103rile protocoalelor de rutare, este permis\u0103 rularea programelor arbitrari de la ter\u021bi produc\u0103tori. Utilizarea nucleului Linux nemodificat simplific\u0103 semnificativ gestionarea patch-urilor pentru vulnerabilit\u0103\u021bi \u0219i crearea de extensii. Se declar\u0103 oportunitatea de a accesa utilitarele, patch-urile \u0219i pachetele Linux, precum \u0219i suport pentru rularea \u00een containere izolate.
\nSe suport\u0103 definirea punctelor de control pentru a reveni la modific\u0103ri \u00een cazul unor probleme.<\/p>\n

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

Managementul poate fi realizat prin gNMI<\/a><\/noindex> (gRPC Network Management Interface), interfa\u021ba de linie de comand\u0103, pluginuri Python \u0219i API-uri bazate pe JSON-RPC.
\nPentru a accesa func\u021bionalitatea serviciilor opera\u021bionale \u00een sistem, se recomand\u0103 utilizarea gRPC \u0219i a protocolului de schimb de date Protocol Buffers. Aplica\u021biile SR Linux pot schimba date despre starea sistemului folosind arhitectura \u201epublish\/subscribe\u201d (pub\/sub), \u00een care sunt utilizate de asemenea gRPC \u0219i Protocol Buffers, iar ca mecanism de livrare garantat\u0103 se folose\u0219te IDB (Nokia Impart Database).
\nPentru structurarea informa\u021biilor despre starea aplica\u021biei \u0219i configura\u021bia utilizat\u0103, se folosesc modele de date YANG (Yet Another Next Generation, RFC-6020<\/a><\/noindex>). <\/p>\n

Implement\u0103rile protocoalelor de re\u021bea, inclusiv Multiprotocol Border Gateway Protocol (MP-BGP), Ethernet VPN (EVPN) \u0219i Virtual Extensible LAN (VXLAN), sunt bazate pe un stack de protocoale bine testat, SR OS (Sistemul de Operare pentru Routerele Nokia), deja utilizat pe mai mult de un milion de routere Nokia. Pentru a abstractiza componentele hardware se folose\u0219te subsistemul XDP<\/a><\/noindex> (eXtensible Data Path).<\/p>\n

Pentru automatizarea desf\u0103\u0219ur\u0103rii opera\u021biunilor de creare, implementare \u0219i configurare a infrastructurii de re\u021bea a datacentrelor, precum \u0219i pentru colectarea \u0219i analiza telemetriei, se propune Nokia Fabric Services Platform (FSP). FSP ofer\u0103, de asemenea, instrumente de simulare software a re\u021belei pentru a simplifica planificarea, proiectarea, testarea \u0219i depanarea re\u021belelor \u00een datacentere. Componentele re\u021belei sunt simulate prin izolare containerizat\u0103 pe baza platformei Kubernetes, permi\u021b\u00e2nd rularea unor instan\u021be SR Linux \u00een medii izolate.<\/p>\n

Practik, FSP permite formarea programatic\u0103 a unei copii virtuale a re\u021belei reale \u0219i utilizarea \u00een aceast\u0103 re\u021bea simulat\u0103 a aceluia\u0219i software (SR Linux \u00een containere) care este folosit pe routere \u0219i comutatoare reale. Mai mult, re\u021beaua real\u0103 \u0219i cea simulat\u0103 folosesc aceea\u0219i configura\u021bie, ceea ce permite utilizarea re\u021belei simulate programatic ca prim\u0103 etap\u0103 pentru introducerea \u0219i testarea modific\u0103rilor. Pe baza mediului simulat, FSP poate genera toate informa\u021biile necesare pentru desf\u0103\u0219urarea re\u021belei reale. <\/p>\n
