Nkag siab Generic UDP Encapsulation

UDP encapsulation yog ib qho txheej txheem ntawm kev ntxiv network headers rau pob ntawv thiab tom qab ntawd encapsulating cov pob ntawv hauv Tus Neeg Siv Datagram Protocol (UDP).

Encapsulating pob ntawv siv UDP pab txhawb kev thauj mus los thoob plaws hauv tes hauj lwm. Los ntawm leveraging Txais Side Scaling (RSS) thiab Equal Cost Multipath (ECMP) routing, UDP muab cov txiaj ntsig tseem ceeb rau kev thauj khoom sib npaug. Kev siv UDP qhov chaw nres nkoj muab entropy rau ECMP hashing thiab muab lub peev xwm los siv IP qhov chaw lossis chaw nres nkoj, thiab L4 Chaw nres nkoj rau kev thauj khoom-ntsuas entropy.

Cov txheej txheem ib txwm muaj xws li Generic Routing Encapsulation (GRE) tuaj yeem ua haujlwm tsuas yog qhov chaw nyob IP sab nraud thiab qhov chaw ntawm qhov chaw nyob. Tej zaum lawv yuav tsis muab kev sib npaug load txaus entropy.

Generic UDP Encapsulation (GUE) yog UDP-based network encapsulation raws tu qauv uas encapsulates IPv4 thiab IPv6 pob ntawv. GUE muab ib txwm UDP encapsulation thiab txhais ib qho ntxiv header, uas pab txiav txim seb lub payload nqa los ntawm IP pob ntawv. Cov header ntxiv tuaj yeem suav nrog cov khoom, xws li tus cim kev sib tham hauv virtual, cov ntaub ntawv kev nyab xeeb rau kev lees paub lossis lees paub qhov GUE header, cov ntaub ntawv tswj kev sib tsoo, thiab lwm yam.

Nyob rau hauv GUE, lub payload yog encapsulated nyob rau hauv ib tug IP pob ntawv uas yuav ua tau IPv4 los yog IPv6 Carrier. UDP header yog ntxiv los muab cov kev txwv tsis pub ntxiv, thiab kev xaiv them nyiaj demultiplexing. Ntawm qhov decapsulation node, Tus Neeg Saib Xyuas IP thiab UDP headers raug tshem tawm, thiab cov pob ntawv raug xa mus raws li kev them nyiaj sab hauv.

Ib pob ntawv GUE muaj cov qauv dav dav:
