Nokia idayambitsa SR Linux network operating system for routers

Kampani ya Nokia представила makina opangira ma network atsopano Linux Service Router (SR Linux) wolunjika kuti zigwiritsidwe ntchito pamanetiweki a malo opangira data ndi malo amtambo. SR Linux ikuwoneka ngati chigawo chachikulu cha mayankho a Nokia Data Center Fabric ndipo idzayikidwa pa Nokia 7250 IXR ndi 7220 IXR mzere wa ma routers. Yankho lochokera pa SR Linux likuyesedwa kale mu Apple ya Danish data center.

Mosiyana ndi machitidwe ena ogwiritsira ntchito zida zapaintaneti zochokera ku Linux kernel, SR Linux imakhalabe ndi mwayi wopeza malo omwe ali pa Linux pa nsanja, zomwe sizibisika kuseri kwa APIs ndi ma interfaces apadera. Ogwiritsa ntchito ali ndi mwayi wopeza ma Linux kernel osasinthidwa ndi mapulogalamu oyambira (bash, cron, Python, etc.), ndipo mapulogalamu apadera amapangidwa pogwiritsa ntchito NetOps Toolkit, yomwe siyimangiriridwa ndi zilankhulo zinazake. Mapulogalamu ozikidwa pa NetOps Toolkit, monga mayendedwe a protocol, amapeza ma API a netiweki osiyanasiyana koma amagwira ntchito ngati zigawo zodziyimira pawokha.

Njirayi imapangitsa kuti muzitha kuyang'anira mapulogalamu mosiyana ndi makina ogwiritsira ntchito; Kuphatikiza pa ntchito zokhazikika, monga kukhazikitsidwa kwa ma protocol, ndizotheka kuyendetsa mapulogalamu osagwirizana ndi opanga ena. Kugwiritsa ntchito kernel yosasinthidwa ya Linux kumathandizira kwambiri kukonza kwa zigamba kuti athetse zovuta komanso kupanga zowonjezera. Kuthekera kofikira zofunikira za Linux, zigamba ndi mapaketi, komanso kuthandizira kuthamanga muzotengera zakutali, zimalengezedwa.
Kufotokozera za cheke pakubweza kusintha ngati pali zovuta kumathandizidwa.

Management ikhoza kuchitidwa kudzera gNMI (gRPC Network Management Interface), mawonekedwe a mzere wamalamulo, mapulagini a Python ndi API yochokera ku JSON-RPC.
Kuti mupeze magwiridwe antchito azinthu zomwe zikuyenda mudongosolo, akufunsidwa kugwiritsa ntchito gRPC ndi Protocol Buffers data exchange protocol. Mapulogalamu a SR Linux amatha kusinthana data ya boma pogwiritsa ntchito kamangidwe ka kusindikiza/kulembetsa (pub/sub), komwe kumagwiritsanso ntchito gRPC ndi Protocol Buffers, ndi kugwiritsa ntchito IDB (Nokia Impart Database) ngati njira yotsimikizika yobweretsera.
Kupanga zambiri za momwe pulogalamuyo ikugwiritsidwira ntchito komanso masinthidwe omwe amagwiritsidwa ntchito, ma data a YANG (Yet Another Next Generation) amagwiritsidwa ntchito. Zamgululi).

Kukhazikitsa ma protocol a netiweki, kuphatikiza Multiprotocol Border Gateway Protocol (MP-BGP), Ethernet VPN (EVPN) ndi Virtual Extensible LAN (VXLAN), zimachokera ku protocol ya SR OS (Nokia Service Router Operating System) yomwe yagwiritsidwa kale ntchito pazambiri. miliyoni rauta Nokia. A subsystem amagwiritsidwa ntchito kufotokoza zigawo za hardware XDP (EXtensible Data Path).

Kupanga, kutumiza, kukhazikitsa ma network network, kusonkhanitsa ndi kusanthula telemetry, Nokia Fabric Services Platform (FSP) imaperekedwa. FSP imaperekanso zida zofananira ndi ma netiweki apulogalamu kuti achepetse kukonza, kupanga, kuyesa ndi kukonza zolakwika za ma data center. Zigawo za netiweki zimayerekezedwa pogwiritsa ntchito kudzipatula kwa chidebe kutengera nsanja ya Kubernetes, yomwe imakupatsani mwayi woyendetsa zochitika za SR Linux m'malo awo akutali.

Kwenikweni, FSP imakupatsani mwayi wopanga makanema enieni a netiweki ndikugwiritsa ntchito pulogalamu yomweyi (SR Linux muzotengera) mumanetiweki omwe amagwiritsidwa ntchito pa ma routers enieni ndi ma switch. Kuphatikiza apo, kusinthika komweko kumagwiritsidwa ntchito pamaneti enieni komanso ofananira, omwe amalola kuti pulogalamu yofananira ndi pulogalamuyo igwiritsidwe ntchito ngati ulalo woyamba wopanga ndi kuyesa kusintha. Kutengera malo ofananirako, FSP imatha kupanga zidziwitso zonse zofunika kuti pakhale netiweki yeniyeni.
