Nokia pr\u00e6senterede<\/a><\/noindex> et nyt netv\u00e6rksoperativsystem Service Router Linux<\/a><\/noindex> (SR Linux), der er orienteret<\/a><\/noindex> til brug i netv\u00e6rksinfrastrukturen i datacentre og cloud-milj\u00f8er. SR Linux betragtes som en n\u00f8glekomponent i Nokias Data Center Fabric-l\u00f8sninger og vil blive installeret p\u00e5 routerne i Nokia 7250 IXR og 7220 IXR-serien. L\u00f8sningen baseret p\u00e5 SR Linux er allerede under test i Apples nye datacenter i Danmark.<\/p>\n

I mods\u00e6tning til andre operativsystemer til netv\u00e6rksudstyr baseret p\u00e5 Linux-kernen, bevarer SR Linux adgangen til det underliggende Linux-milj\u00f8, som ikke er skjult bag specialiserede API'er og interfaces. Brugere har adgang til den uh\u00e5ndterede Linux-kernel og grundl\u00e6ggende systemapplikationer (bash, cron, Python osv.), og specifikke applikationer oprettes ved hj\u00e6lp af NetOps Toolkit, som ikke er knyttet til bestemte programmeringssprog. Applikationer baseret p\u00e5 NetOps Toolkit, for eksempel implementeringer af routingprotokoller, har adgang til forskellige netv\u00e6rks-API'er, men fungerer som uafh\u00e6ngige komponenter. <\/p>\n

Denne tilgang muligg\u00f8r at styre applikationer uafh\u00e6ngigt af operativsystemet. For eksempel kan man opdatere applikationen uden at \u00e6ndre systemet, eller opdatere operativsystemet uden at rekonstruere applikationerne. Udover de indbyggede applikationer, s\u00e5som implementeringer af routingprotokoller, tillades det at k\u00f8re programmer fra tredjepartsproducenter. Brugen af den uh\u00e5ndterede Linux-kernel forenkler betydeligt vedligeholdelsen af patches til s\u00e5rbarheder og oprettelsen af udvidelser. Der er mulighed for adgang til Linux-v\u00e6rkt\u00f8jer, patches og pakker, samt st\u00f8tte til k\u00f8rsel i isolerede containere.
\nDer underst\u00f8ttes definition af kontrolpunkter til tilbagef\u00f8rsel af \u00e6ndringer i tilf\u00e6lde af problemer.<\/p>\n

Management kan udf\u00f8res via gNMI<\/a><\/noindex> (gRPC Network Management Interface), kommandolinjegr\u00e6nseflade, Python-plugins og JSON-RPC-baserede API'er.
\nFor accessing the functionality of services operating in the system, it is recommended to use gRPC and the Protocol Buffers data exchange protocol. SR Linux applications can exchange state information using the 'publish\/subscribe' (pub\/sub) architecture, which also employs gRPC and Protocol Buffers, and IDB (Nokia Impart Database) is used as the mechanism for guaranteed delivery.
\nFor structuring information about the application state and configuration used, YANG (Yet Another Next Generation) data models are employed. RFC-6020<\/a><\/noindex>). <\/p>\n

Implementations of network protocols, including Multiprotocol Border Gateway Protocol (MP-BGP), Ethernet VPN (EVPN), and Virtual Extensible LAN (VXLAN), are based on the proven protocol stack SR OS (Nokia Service Router Operating System), already utilized on over a million Nokia routers. A subsystem is used to abstract from hardware components. XDP<\/a><\/noindex> (eXtensible Data Path).<\/p>\n

To automate the operations for creating, deploying, and configuring the data center network infrastructure, as well as collecting and analyzing telemetry, Nokia Fabric Services Platform (FSP) is proposed. FSP also provides tools for software network simulation to simplify planning, design, testing, and debugging of data center networks. Network components are simulated using container isolation based on the Kubernetes platform, allowing separate instances of SR Linux to run in their isolated environments.<\/p>\n

Essentially, FSP allows for the programmatic formation of a virtual copy of the actual network and uses the same software (SR Linux in containers) in this simulated network as is used on real routers and switches. Moreover, the same configuration is used in both the real and simulated networks, enabling the programmatically simulated network to be the first step for implementing and testing changes. Based on the simulated environment, FSP can generate all the necessary information for deploying a real network. <\/p>\n
