Iisokethi zesizinda se-Unix zihlala ziphindwe kabini ngokukhawuleza njenge-socket ye-TCP xa bobabini oontanga bekwi-host host efanayo. Iiprothokholi zommandla we-Unix aziyondlela yokwenyani yeprotocol, kodwa yindlela yokwenza umxhasi/unxibelelwano lomncedisi kumamkeli omnye usebenzisa i-API efanayo esetyenziswa kubaxhasi kunye nabancedisi kwiinginginya ezahlukeneyo.
Lukhawuleza kangakanani unxibelelwano lwesokhethi?
Kumatshini okhawuleza kakhulu unokufumana i-1 GB / s kumxhasi omnye. Ngabathengi abaninzi unokufumana i-8 GB/s. Ukuba unekhadi le-100 Mb ungalindela malunga ne-11 MB/s (bytes ngomzuzwana). Kwi-ethernet ye-10 ye-Gig-E ungafumana ukuya kuthi ga kwi-1 GB/s nangona kunjalo ungafumana isiqingatha salo ngaphandle kokuba inkqubo yakho icudiswe kakhulu.
Kutheni le nto i-UNIX ifuna isiseko sommandla?
Iziseko zommandla we-UNIX zenza unxibelelwano olusebenzayo phakathi kweenkqubo ezisebenza kwiprosesa efanayo ye-z/TPF. Iziseko zesizinda se-UNIX zixhasa zombini i-stream-oriented, i-TCP, kunye ne-datagram-oriented, i-UDP, i-protocol. Awunako ukuqalisa isiseko sommandla weUNIX kwiprothokholi ekrwada.
Ngaba iisokethi ze-UNIX zihamba kabini?
Iisokethi zi-bidirectional, zibonelela ngeendlela ezimbini zokuhamba kwedatha phakathi kweenkqubo ezinokuthi zibe nomzali omnye. … Imibhobho ibonelela ngokusebenza okufanayo. Nangona kunjalo, azikho unidirectional, kwaye zinokusetyenziswa kuphela phakathi kweenkqubo ezinomzali omnye.
Yintoni uqhagamshelwano lwesokethi ye-Unix?
I-Unix domain socket okanye i-IPC socket (i-inter-process communication socket) isiphelo sonxibelelwano lwedatha yokutshintshiselana kwedatha phakathi kweenkqubo eziqhutywa kwinkqubo efanayo yokusingatha. Iintlobo zesokethi ezisebenzayo kwi-domain ye-UNIX zezi: SOCK_STREAM (thelekisa ne-TCP) - yesokethi ejolise kumsinga.
Yintoni indlela ye-socket ye-Unix?
Iziseko zommandla we-UNIX zithiywe ngeendledlana ze-UNIX. Umzekelo, isokethi inokubizwa ngegama /tmp/foo. Iziseko zommandla we-UNIX zinxibelelana kuphela phakathi kweenkqubo kwinginginya enye. … Iintlobo zesokethi zichaza iimpawu zonxibelelwano ezibonakala kumsebenzisi. Iisokethi ze-intanethi zibonelela ngokufikelela kwiiprothokholi zothutho ze-TCP/IP.
Yintoni ifayile yesokhethi kwiLinux?
Isokhethi yifayile yeenkqubo zokutshintshiselana ngedatha. … Isokethi yommandla we-Unix okanye isokethi ye-IPC (isiseko sonxibelelwano lwenkqubo phakathi kwenkqubo) sisiphelo sonxibelelwano lwedatha yokutshintshiselana ngedatha phakathi kweenkqubo eziqhutywa kwinkqubo efanayo yomamkeli.
Yintoni izibuko le-Unix?
Ngenjongo yethu, izibuko lizakuchazwa njengenani elipheleleyo phakathi kwe-1024 kunye ne-65535. … Oku kungenxa yokuba onke amanani ezibuko amancinci kuno-1024 athathwa njengaziwayo - umzekelo, i-telnet isebenzisa i-port 23, i-http isebenzisa i-80, i-ftp isebenzisa i-21, kwaye nangokunjalo.
What is socket networking?
Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
What is Af_unix?
The AF_UNIX (also known as AF_LOCAL) socket family is used to communicate between processes on the same machine efficiently. Traditionally, UNIX domain sockets can be either unnamed, or bound to a filesystem pathname (marked as being of type socket).
Yintoni i-Unix socket kwi-Docker?
Ikawusi sisokethi seUNIX esimanyelwa yiDocker daemon. Yeyona ndawo yokungena yeDocker API. Ikwanokuba yisokethi ye-TCP kodwa ngokungagqibekanga ngenxa yezizathu zokhuseleko i-Docker ayigqibekanga ukusebenzisa isokhethi ye-UNIX. Umxhasi weDocker cli usebenzisa le socket ukwenza imiyalelo yedocker ngokungagqibekanga. Ungazihoya ezi setingi ngokunjalo.
What Unix function lets a socket receive connections?
The recv function is used to receive data over stream sockets or CONNECTED datagram sockets. If you want to receive data over UNCONNECTED datagram sockets you must use recvfrom(). You can use read() system call to read the data.
Yintoni ikhompyuter ye-Unix?
I-UNIX yinkqubo yokusebenza eyaqala ukuphuhliswa ngo-1960s, kwaye ibiphantsi kophuhliso oluqhubekayo ukusukela ngoko. Ngenkqubo yokusebenza, sithetha uluhlu lweenkqubo ezenza ikhompyuter isebenze. Yinkqubo ezinzileyo, yabasebenzisi abaninzi, imisebenzi emininzi yeeseva, iidesktops kunye neelaptops.
