WolfIP: Yakareruka TCP / IP stack isina simba rekugovera ndangariro

Mutengo Wakavanzika Wekubatana: Dynamic Memory muEmbedded Systems

Munyika yemasisitimu akadzamirwa neIoT, kubatana hakuchisiri kweumbozha — chinhu chinodiwa. Asi kune vanogadzira vanovaka zvigadziriso-zvinomanikidzirwa zvishandiso, kushandisa yakazara TCP/IP network stack inogona kunzwa sekuyedza kukwana pegi yeskweya mugomba rakatenderera. Traditional stacks, yakagadzirirwa general-chinangwa komputa, inotsamira zvakanyanya pane ine simba ndangariro kugoverwa (malloc/yemahara), kuunza isingafungidzike latency, kupatsanurwa kwendangariro, uye yakaoma kukanganisa kukanganisa. Idzi injodzi idzo mishoni-yakakosha maindasitiri, mota, uye zvigadziriso zvekurapa zvisingakwanisi. Apa ndipo panochinjika paradigm yakananga kune deterministic, yakavimbika networking inova yakakosha, inoenzanisirwa nemhinduro dzakaita seWolfIP lightweight TCP/IP stack.

WolfIP: Engineering Certainty muNetiweki Kukurukurirana

WolfIP yakaonda, yakakwirira-inoshanda TCP/IP stack yakanyatso gadzirirwa chaiyo-nguva uye kuchengetedzwa-kwakakosha nharaunda. Yayo musimboti dhizaini uzivi inobvisa yekutanga sosi yekumhanyisa nguva kusagadzikana: dynamic memory kugoverwa. Ne eschewing malloc uye yemahara zvachose mukuita kwayo kwepakati, WolfIP inopa nhanho yekutemesa maitiro ari goridhe-yakajairwa mukusimudzira kwakadzika. Yese inodiwa ndangariro inofanopihwa uye inogadziriswa statically kana kubva mushandisi-akapihwa madziva pakutanga. Izvi zvinoreva kuti hapana kukundikana kusingatarisirwe kugoverwa panguva yekushanda, hapana zvishoma nezvishoma kupatsanurwa kwendangariro kunotungamira kune zvisinganzwisisike kubondera kwemavhiki mukushandiswa, uye kunoenderana, kuita kusingatarisirwe kunogona kuvimbwa nevanovaka masisitimu.

"Mune deterministic systems, mubvunzo haumbofi * kana * packet ichagadziriswa, asi chaizvo * nguva *. Kubvisa dynamic memory allocation kubva kune network layer idanho rekutanga kune iyo vimbiso."

Zvakakosha zveZero-Malloc Network Stack

Kutora chitunha chakareruka seWolfIP chinopa mabhenefiti ekare uye enguva refu ekugadzikana kwechigadzirwa uye kufambiswa kwebasa. Aya mabhenefiti anogadzirisa zvakanangana nemarwadzo ekuunza zvakabatana, zvigadzirwa zvemodular kumusika.

• Deterministic Performance: Nguva yekushandisa uye ndangariro tsoka zvinotarisika, zvichigonesa mhinduro yakavimbika yenguva chaiyo uye kurerutsa chitupa chekuchengetedza mwero (se ISO 26262 kana IEC 62304).
• Yakabvisa Kupatsanurwa: Pasina kushandiswa kwemurwi kune simba, sisitimu inodzivirira kupatsanurwa kwendangariro, ichiva nechokwadi chekugadzikana kwenguva refu uye kubvisa boka rese rezvipembenene.
• Yakaderedzwa Memory Overhead: The stack yakabatana zvisingaite, yakanakira mamicrocontroller ane RAM shoma, inobvumira zvimwe zviwanikwa zve core application logic.
• Kugadzirisa Zvakareruka & Chengetedzo: Zvikamu zvishoma zvinofamba mukugadzirisa kwendangariro zvinoreva kugadzirisa kuri nyore uye kuderedzwa kwenzvimbo yekurwisa kwehuori hwendangariro.

Kubatanidza Reliable Connectivity muModular Business OS

Kumapuratifomu akaita seMewayz, iyo modular bhizinesi OS inopa simba mabhizinesi kuvaka akarongedzerwa, scalable inoshanda software, kuvimbika kwechikamu hakugone kutaurirana. Kana iyo Mewayz module kana yemutengi yekumucheto mudziyo inoda yakasimba network kutaurirana - ingave ye telemetry, kure kure, kana yepakati-sevhisi kuwanikwa - network network haigone kuve mutoro. Kubatanidza dhizaini yekumisikidza seWolfIP inoenderana zvakakwana nehuchenjeri hwaMewayz hwekupa akasimba, anoumbika zvivharo zvekuvaka. Iyo inovimbisa kuti iyo yekubatanidza layer yechero mhinduro yakavimbika uye inogoneka senge bhizinesi logic modules yakavakirwa pamusoro payo. Izvi zvinobvumira vanogadzira vanoshandisa iyo Mewayz ecosystem kuti vatarise kugadzira kukosha-akawedzera maficha, vane chivimbo chekuti data ravo richafamba nemazvo uye zvakachengeteka pane network.

Kune mabhizinesi anoshandisa chikuva seMewayz kuendesa mashandiro akaomarara mumunda, kusarudza zvinhu zvine kuvimbika kwakadaro inzira yakanaka. Iyo yeramangwana-humbowo zvigadzirwa, inoderedza lifecycle kugadzirisa mutengo, uye inovaka mushandisi kuvimba. Pakupedzisira, mhinduro dzeIoT dzakanyanya kuvandudzwa dzinenge dziri idzo dzinobatanidza kwete zvisina musono, asiwo dzakatsiga, kushandura kuvimbika kwetiweki kubva pakunetsa kunoramba kuripo kuita hwaro hwakanyarara, hwakavimbika.
