Nhanganyaya nezveSNMP
Rakareruka Network Management Protocol (SNMP) iapplication-layer protocol inopa meseji fomati yekutaurirana pakati pemaneja eSNMP nevamiririri. SNMP inopa yakamisikidzwa chimiro uye mutauro wakajairika unoshandiswa kutarisisa uye manejimendi emidziyo munetiweki.
Iyo SNMP framework ine zvikamu zvitatu:

SNMP maneja - Iyo SNMP maneja inoshandiswa kudzora uye kutarisa zviitiko zvevatambi venetiweki vachishandisa SNMP.

SNMP mumiriri - Iyo SNMP mumiriri ndiyo chikamu chesoftware mukati memudziyo unochengetedzwa inochengetedza iyo data yechishandiso uye inoshuma iyi data, sezvinodiwa, kutonga masisitimu.
MIB - Iyo Management Information Base (MIB) inzvimbo yekuchengetera ruzivo ruzivo rwemanetiweki manejimendi ruzivo, iyo ine muunganidzwa wezvinhu zvinogadziriswa.

Maneja anogona kutumira zvikumbiro zvemumiririri kuti atore uye kuseta MIB kukosha. Mumiririri anogona kupindura kune izvi zvikumbiro.
Zvisineyi nekudyidzana uku, mumiririri anogona kutumira zviziviso zvisina kukumbirwa (misungo kana kuzivisa) kune maneja kuti azivise maneja wetiweki mamiriro.

SNMP Operations

ENCS Switch Monitoring	NFVIS 4.5.1	Ichi chimiro chinokubvumira kuverenga chiyero che data che ENCS switch ports zvichibva pane data yakaunganidzwa kubva kuchinja kwe ENCS.

Kune ENCS switch ports, chiyero chedata chinoverengerwa zvichienderana nedata rakaunganidzwa kubva kuENCS switch uchishandisa periodic polling masekonzi gumi ega ega. Kupinza uye kuburitsa mwero mu Kbps inoverengerwa zvichienderana neoctets inounganidzwa kubva pachinja masekonzi gumi ega ega.
Iyo formula inoshandiswa pakuverenga ndeyekutevera:
Avg rate = (Avg rate - Current interval rate) * (alpha) + Current Interval rate.
Alfa = multiplier/ Chikero
Multiplier = chiyero - (chiyero * compute_interval)/ Load_interval
Ipo compute_interval ndiyo nguva yekuvhota uye Load_interval ndiyo yeinterface yekuremerwa = 300 sec uye chiyero = 1024.

Nekuti iyo data inowanikwa zvakananga kubva kune switch iyo kbps mwero inosanganisira Frame Cheki Sequence (FCS) bytes.
Iyo bandwidth kuverenga inotambanudzirwa kune ENCS switch port chiteshi uchishandisa iyo yakafanana formula. Kupinza uye kuburitsa mwero mukbps inoratidzwa zvakasiyana kune yega yega gigabit Ethernet chiteshi pamwe neinowirirana port-chiteshi boka iro chiteshi chakabatana nacho.
