Palapala puke

ʻIke pono

I ʻole e lilo ka ʻatikala i pepa, ua haʻalele wau i kekahi mau kikoʻī loea (me nā loulou i ka palapala kahi e hiki ai iā ʻoe ke heluhelu e pili ana iā lākou).

Ma kēia pili, hāʻawi wau iā ʻoe i nā kumuhana e maikaʻi (akā ʻaʻole pono) e ʻike ma mua o ka heluhelu ʻana:

Mahele 1: kekahi manaʻo

He kahua SDN wehe no ka hooponopono ana a me ka hoohana ana i na ano a pau, i kākoʻo ʻia e Linux kikowaena
Java i loko
Ma muli o ke Ana Hoʻohālikelike Hana Hana Hoʻohālike (MD-SAL)
Hoʻohana i nā hiʻohiʻona YANG no ka hoʻopuka ʻokoʻa ʻana i nā API RESTCONF no nā polokalamu pūnaewele

ʻO ka module nui no ka hoʻokele pūnaewele. Ma ia mea mākou e kamaʻilio ai me nā mea pili. Mālama ʻia ma kāna API ponoʻī.

Hiki iā ʻoe ke heluhelu hou aku e pili ana i OpenDaylight maanei.

Mea hana hoʻāʻo API
Maʻalahi a maʻalahi hoʻi e hoʻohana

I kā mākou hihia, makemake mākou iā ia i mea e hoʻouna ai i nā noi REST i ka OpenDaylight API. Hiki iā ʻoe, ʻoiaʻiʻo, hoʻouna i nā noi me ka lima, akā ma ka Postman ʻike maopopo loa nā mea āpau a kūpono i kā mākou kumu.

No ka poʻe makemake e ʻeli: ua kākau ʻia ka nui o nā mea aʻo ma luna (Eia kekahi lā).

Mea hana no ka lawe ʻana i nā mea hoʻokele virtual ma Docker
Kākoʻo: Cisco XRv, Juniper vMX, Arista vEOS, Nokia VSR, etc.
Open Source

He mea hana hoihoi akā ʻike iki ʻia. I kā mākou hihia, e hoʻohana mākou iā ia e holo iā Juniper vMX a me Cisco xRV9000 ma kahi Ubuntu 20.04 LTS maʻamau.

Hiki iā ʻoe ke heluhelu hou e pili ana iā ia ma ʻaoʻao papahana.

Mahele 2: Lab

Ma kēia kumu aʻo, e hoʻonohonoho mākou i kēia ʻōnaehana:

Pehea hana i keia hana

Juniper vMX piʻi i loko Docker ipu (by means Vrnetlab) a me nā hana ma ke ʻano he mea hoʻokele virtual maʻamau.
ODL pili i ka router a hiki iā ʻoe ke hoʻomalu iā ia.
Kahuhahu hoʻokuʻu ʻia ma kahi mīkini ʻokoʻa a ma o ia mea mākou e hoʻouna ai i nā kauoha ODL: e hoʻohui / wehe i ke alalai, hoʻololi i ka hoʻonohonoho, etc.

Manaʻo manaʻo no ka mea hana o ka ʻōnaehana

Juniper vMX и ODL makemake i nā kumuwaiwai he nui no kā lākou hana paʻa. Hoʻokahi wale nō vMX noi no 6 Gb o RAM a me 4 cores. No laila, ua hoʻoholo ʻia e hoʻoneʻe i nā "kaumaha" āpau i kahi mīkini ʻokoʻa (Heulett Packard Enterprise MicroServer ProLiant Gen8, Ubuntu 20.04 LTS). ʻO ka mea alalai, ʻoiaʻiʻo, ʻaʻole "lele" ma luna o ia, akā lawa ka hana no nā hoʻokolohua liʻiliʻi.

Mahele 3: Hoʻonohonoho i ka OpenDaylight

ʻO ka mana o kēia manawa o ODL i ka manawa o kēia kākau ʻana ʻo Magnesium SR1

1) Hoʻokomo ʻO Java OpenJDK 11 (no ka hoʻokomo kikoʻī hou aku maanei)

ubuntu:~$ sudo apt install default-jdk

2) E huli a hoʻoiho i ka hana hou loa ODL mai kēia wahi
3) Wehe i ka waihona i hoʻoiho ʻia
4) E hele i ka papa kuhikuhi hopena
5) Hoʻomaka ./bin/karaf

Ma kēia ʻanuʻu ODL pono e hoʻomaka a ʻike mākou iā mākou iho i ka console (Hoʻohana ʻia ʻo Port 8181 no ke komo ʻana mai waho, a mākou e hoʻohana ai ma hope).

A laila, hoʻokomo ODL hiʻonai hoʻolālā ʻia e hana me nā protocols NETCONF и RESTCONF. E hana i kēia ma ka console ODL hana mākou:

opendaylight-user@root> feature:install odl-netconf-topology odl-restconf-all

ʻO kēia ka hoʻonohonoho maʻalahi. ODL hoʻopau ʻia. (No nā kikoʻī hou aku, e ʻike maanei).

Mahele 4: Hoʻonohonoho Vrnetlab

Hoʻomākaukau ʻōnaehana

Ma mua o ke kau ʻana Vrnetlab pono ʻoe e hoʻokomo i nā pūʻolo i koi ʻia no kāna hana. E like me Docker, hele, sshpass:

ubuntu:~$ sudo apt update
ubuntu:~$ sudo apt -y install python3-bs4 sshpass make
ubuntu:~$ sudo apt -y install git
ubuntu:~$ sudo apt install -y 
    apt-transport-https ca-certificates 
    curl gnupg-agent software-properties-common
ubuntu:~$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

   $(lsb_release -cs) 
   stable"
ubuntu:~$ sudo apt update
ubuntu:~$ sudo apt install -y docker-ce docker-ce-cli containerd.io

Ke hoʻokomo nei iā Vrnetlab

E hoʻoulu Vrnetlab clone i ka waihona e pili ana mai github:

ubuntu:~$ cd ~
ubuntu:~$ git clone https://github.com/plajjan/vrnetlab.git

E hele i ka papa kuhikuhi vrnetlab:

ubuntu:~$ cd ~/vrnetlab

Maanei hiki iā ʻoe ke ʻike i nā palapala āpau e pono ai e holo. E ʻoluʻolu e hoʻomaopopo ua hana ʻia kahi papa kuhikuhi pili no kēlā me kēia ʻano mea ala ala:

ubuntu:~/vrnetlab$ ls

E hana i kiʻi o ka router

ʻO kēlā me kēia router i kākoʻo ʻia Vrnetlab, loaʻa i kāna kaʻina hana hoʻonohonoho kūʻokoʻa. I ka manawa Juniper vMX pono mākou e hoʻouka i ka waihona .tgz me ke alalai (hiki iā ʻoe ke kiʻi iā ia mai kūhelu paena) i ka papa kuhikuhi vmx a holo i ke kauoha make:

ubuntu:~$ cd ~/vrnetlab/vmx
ubuntu:~$ # Копируем в эту директорию .tgz архив с роутером
ubuntu:~$ sudo make

Ke kūkulu ʻana i kiʻi vMX e lawe ma kahi o 10-20 mau minuke. ʻO ka manawa kēia e hele ai e kiʻi i ka kofe!

No ke aha ka lōʻihi, ke nīnau nei ʻoe?

Unuhi ka pane mea kākau i kēia nīnau:

"ʻO kēia no ka mea ʻo ka manawa mua i hoʻomaka ʻia ka VCP (Control Plane), heluhelu ia i kahi faila config e hoʻoholo ai inā e holo ʻo ia ma ke ʻano he VRR VCP ma vMX. Ma mua, ua hana ʻia kēia hoʻomaka ʻana i ka wā hoʻomaka Docker, akā ʻo ia ka manaʻo o ka VCP ua hoʻomaka hou ʻia i hoʻokahi manawa ma mua o ka loaʻa ʻana o ka mea hoʻokele virtual, ka hopena i kahi manawa boot lōʻihi (e pili ana i 5 mau minuke) I kēia manawa ua hana ʻia ka holo mua o ka VCP i ka wā o ke kūkulu ʻana i ke kiʻi Docker, a no ka mea ʻaʻole hiki ke holo ka hale Docker me ka - - koho pono, 'o ia ho'i, hana 'o qemu me ka wikiwiki 'ole o ka lako KVM a no laila, lō'ihi loa ke kūkulu 'ia 'ana. ʻAʻole makaʻu nui no ka mea hana mākou i hoʻokahi kiʻi, akā hoʻomaka mākou i nā mea he nui. "

Ma hope o ka ʻike ʻana i ke kiʻi o kā mākou router Docker:

ubuntu:~$ sudo docker image list
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

E wehe i ka pahu vr-vmx

Hoʻomaka mākou me ke kauoha:

ubuntu:~$ sudo docker run -d --privileged --name jun01 b1b2369b453c

A laila, hiki iā mākou ke ʻike i ka ʻike e pili ana i nā pahu hana:

ubuntu:~$ sudo docker container list

Ke hoʻokuʻi ʻana i ka router

Hiki ke kiʻi ʻia ka IP address o ke kikowaena pūnaewele o ke alalai me kēia kauoha:

ubuntu:~$ sudo docker inspect --format '{{.NetworkSettings.IPAddress}}' jun01

Paʻamau, Vrnetlab hana i ka mea hoʻohana ma ka router vrnetlab/VR-netlab9.

Hoʻopau kēia i ka hoʻonohonoho router.

Hiki ke loaʻa nā ʻōlelo paipai no nā mea hoʻokele o nā mea kūʻai like ʻole ma papahana github i loko o nā papa kuhikuhi.

Mahele 5: Leta - hoʻohui i ke alalai iā OpenDaylight

Hoʻokomo ʻia ka mea leka uila
