Malamalama Generic UDP Encapsulation

UDP encapsulation o se metotia o le faʻaopoopoina o ulutala fesoʻotaʻiga i afifi ona faʻapipiʻi ai lea o pepa i totonu ole User Datagram Protocol (UDP).

O le fa'apipi'iina o pepa e fa'aaoga ai le UDP e fa'afaigofie ai felauaiga i luga o feso'otaiga. E ala i le fa'aogaina o le Receive Side Scaling (RSS) ma le Equal Cost Multipath (ECMP) routing, ua maua ai e le UDP ni fa'amanuiaga taua mo le fa'apaleni o uta. O le faʻaogaina o le UDP puna puna e tuʻuina atu ai le entropy i le ECMP hashing ma maua ai le gafatia e faʻaoga ai le puna IP poʻo le taunuʻuga, ma le L4 Port mo le faʻaogaina o le uta-paleni entropy.

O faiga masani e pei o le Generic Routing Encapsulation (GRE) e mafai ona taulimaina na'o le tuatusi IP Source i fafo ma vaega o le tuatusi o lo'o i ai. Atonu latou te le lava saunia entropy faapaleni uta.

Generic UDP Encapsulation (GUE) o se UDP-based network encapsulation protocol e faʻapipiʻi IPv4 ma IPv6 packets. GUE e tuʻuina atu le faʻapipiʻiina o le UDP ma faʻamatalaina se ulutala faaopoopo, lea e fesoasoani e fuafua ai le uta o loʻo tauaveina e le pusa IP. O le ulutala faaopoopo e mafai ona aofia ai mea, e pei o se faʻamatalaga fesoʻotaiga vavave, faʻamatalaga saogalemu mo le faʻamaonia poʻo le faʻamaoniaina o le ulutala GUE, faʻamatalaga faʻatonutonu faʻamaʻi, ma isi.

I le GUE, o le uta o loʻo faʻapipiʻiina i totonu o se pusa IP e mafai ona avea ma IPv4 poʻo IPv6 Carrier. O le ulutala UDP ua faʻaopoopoina e tuʻuina atu ai faʻamaufaʻailoga faʻapipiʻi, ma le faʻaogaina o le faʻaogaina o totogi. I le node decapsulation, ua aveese le Carrier IP ma le UDP ulutala, ma o le afifi o loʻo tuʻuina atu e faʻatatau i le uta i totonu.

O le taga GUE e iai le fa'asologa lautele:

Mo example, i lenei faʻataʻitaʻiga, pe a tuʻuina atu le faʻamaumauga mai le Host 1 i le Host 2. O le server e galue o se GUE encapsulator e auina atu faʻamaumauga mai le Host 1. O le server, i le isi itu o loʻo mauaina faʻamaumauga, faʻamaonia le faʻamatalaga mo le fa'aulu fa'auluulu IP ma UDP ma fa'ate'a fa'amaumauga.

GUE e iai suiga eseese, ae o le fesuiaiga 1 o le GUE e mafai ai ona tu'u sa'o le IPv4 ma le IPv6 i le UDP. O lenei metotia e faʻasaoina ai le faʻapipiʻiina i luga o soʻotaga mo le faʻaogaina o le IP encapsulation, ma e le manaʻomia foi ona tuʻufaʻatasia se isi numera o le UDP mo le IP-over-UDP encapsulation.

Fa'amanuiaga ole fa'aogaina ole GUE
  • Fa'ataga le fa'apipi'i sa'o o uta, pei o le IPv4 ma le IPv6 i totonu o le pusa UDP.
    • E mafai ona e fa'aogaina le uafu UDP mo le fa'aitiitia o uta.
    • E mafai ona e fa'aogaina se uafu UDP e tasi, fa'atagaina faiga e fa'aogaina fa'ata'ita'iga fa'ata'ita'i e iloa ai uta.
  • Fa'aogaina le ulutala UDP mo fa'ailoga entropy e ala i le fa'aigoaina o le tuple-based source port.
  • E fa'aogaina tuatusi IP fa'apogai mo le fa'avasegaina o uta-paleni. E mafai fo'i ona fa'amutaina le taunu'uga e fa'atatau i se subnet e tu'uina atu ai vaega fa'aopoopo mo le entropy.
  • Aloese mai le taulimaina fa'apitoa mo nodes transist aua na'o latou va'aia se pusa IP-UDP ma sina uta.
  • Fa'afaigofie le fa'atinoina o le fa'aoga UDP ma le GUE. E mafua ona o le auala faʻapipiʻi tuusaʻo o uta i totonu o le UDP.
