Mylinking™ Network Packet Brokers inotsigirwa neReal-time Traffic Detection:Yakatsigira manyuko e "Capture Physical Port (Data Acquisition)", "Packet Feature Description Field (L2 - L7)", uye rumwe ruzivo rwekutsanangura flexible traffic filter, yekutora data re network panguva chaiyo yekuona nzvimbo dzakasiyana, uye ichachengetwa data renguva chaiyo mushure mekutorwa uye kuonekwa mumudziyo kuti utorezve ongororo yenyanzvi yekuita kana kushandisa maficha ayo ekuongorora emudziyo uyu kuti utarise zvakadzama.
Ungangoda kuziva kuti OSI Model 7 Layers chii?
Tisati tanyatsoongorora modhi yeOSI, tinofanira kunzwisisa mamwe mazwi ekutanga ekubatana kuti tibatsire hurukuro inotevera.
Maponde
Node chinhu chipi zvacho chemagetsi chakabatana nenetwork, senge komputa, printer, router, nezvimwewo. MaNode anogona kubatanidzwa kuti agadzire network.
Chinongedzo
Chinongedzo chinobatanidza ma node ari mu network, anogona kunge akabatana ne waya (senge Ethernet) kana kuti asina waya (senge WiFi) uye anogona kunge ari point-to-point kana multipoint.
Maitiro ekushandisa
Protocol mutemo wema nodes maviri ari mu network kuti achinje data. Mitemo iyi inotsanangura syntax, semantics, uye synchronization yekutumira data.
Network
Network inoreva muunganidzwa wemidziyo, yakaita semakombiyuta, maprinta, ayo akagadzirirwa kugovana data.
Topology
Topology inotsanangura kuti ma nodes ne link zvinogadziriswa sei mu network uye chinhu chakakosha che network structure.
Chii chinonzi OSI model?
Muenzaniso weOSI (Open Systems Interconnection) unotsanangurwa neInternational Organisation for Standardization (ISO) uye unokamura network dzemakombiyuta kuita nhanho nomwe kuti zvibatsire kutaurirana pakati pemasystem akasiyana. Muenzaniso weOSI unopa dhizaini yakajairika yemagadzirirwo enetwork, kuitira kuti zvishandiso zvinobva kuvagadziri vakasiyana zvigone kutaurirana.
Maturikirwo manomwe emuenzaniso weOSI
1. Dura remuviri
Ane basa rekutumira ma "raw bit streams", anotsanangura hunhu hwezvinhu zvakaita se "cables" uye "wireless signals". Data rinotumirwa muma "bits" pa "layer" iyi.
2. Chikwata cheData Link
Mafuremu edata anotumirwa kuburikidza nechiratidzo chemuviri uye ane basa rekuona zvikanganiso uye kudzora kuyerera kwedata. Data rinogadziriswa mumafuremu.
3. Rutivi rweNetiweki
Inotarisira kutakura mapaketi pakati pema network maviri kana anopfuura, kugadzirisa nzira dzekutumira mashoko (routing) uye kugadzirisa kero (logical addressing). Data rinogadziriswa mumapaketi.
4. Chigadziko chekutakura
Inopa data kubva kumagumo kusvika kumagumo, ichivimbisa kuti data rakarurama uye rakatevedzana, kusanganisira connection directed protocol TCP uye connectionless protocol UDP. Data iri muzvikamu zvezvikamu (TCP) kana datagrams (UDP).
5. Chikamu cheMusangano
Tarisira zvikamu pakati pezvikumbiro, zvine mutoro wekugadzwa kwezvikamu, kugadzirisa, uye kugumisa.
6. Chinyorwa cheMharidzo
Bata kushandurwa kwefomati yedata, encoding yemavara, uye encryption yedata kuti uve nechokwadi chekuti data rinogona kushandiswa nemazvo ne application layer.
7. Chimiro Chekushandisa
Inopa vashandisi masevhisi enetwork zvakananga, kusanganisira maapplication nemasevhisi akasiyana-siyana, akadai seHTTP, FTP, SMTP, nezvimwewo.
Chinangwa chechikamu chimwe nechimwe chemuenzaniso weOSI nematambudziko azvo angangoitika
Chikamu 1: Chikamu Chemuviri
Chinangwa: Chikamu chemuviri chinotarisa hunhu hwezvishandiso zvese zvemuviri nemasaini. Chine basa rekugadzira nekuchengetedza hukama chaihwo pakati pezvishandiso.
Kugadzirisa matambudziko:
○Tarisa kana tambo nezvinongedzo zvakakuvara.
○Iva nechokwadi chekuti zvishandiso zvemuviri zvinoshanda nemazvo.
○Simbisa kuti magetsi anowanikwa zvakanaka.
Chikamu chechipiri: Chikamu cheData Link
Chinangwa: Rutivi rwekubatanidza data rwuri pamusoro perutivi rwemuviri uye rune basa rekugadzira furemu uye kuona zvikanganiso.
Kugadzirisa matambudziko:
○Matambudziko angangoitika echikamu chekutanga.
○Kukundikana kwekubatana pakati pema nodes.
○Kuzara kwenetwork kana kudonha kwemafuremu.
Chikamu 3: Chikamu cheNetwork
Chinangwa: Network layer ine basa rekutumira mapaketi kukero yekuenda, kugadzirisa sarudzo yenzira.
Kugadzirisa matambudziko:
○Tarisa kuti ma routers nema switch akagadzirwa nemazvo.
○Iva nechokwadi chekuti kero ye IP yakagadzirirwa nemazvo.
○Kukanganisa kwekubatanidza kunogona kukanganisa mashandiro echikamu ichi.
Chikamu chechina: Chikamu chekutakura
Chinangwa: Chinyorwa chekufambisa chinovimbisa kutapurirana kwedata kwakavimbika uye chinotarisira kupatsanurwa nekurongwa patsva kwedata.
Kugadzirisa matambudziko:
○Simbisa kuti chitupa (semuenzaniso, SSL/TLS) chapera basa.
○Tarisa kana firewall ichivhara chiteshi chinodiwa.
○Kukoshesa kwetraffic kwakagadzirirwa nemazvo.
Chikamu 5: Chikamu cheSession
Chinangwa: Chikamu chechikamu chine basa rekugadzira, kuchengetedza nekugumisa zvikamu kuitira kuti data riendeswe kumativi maviri.
Kugadzirisa matambudziko:
○Tarisa mamiriro eseva.
○Iva nechokwadi chekuti magadzirirwo eapplication akarurama.
○Zvidzidzo zvinogona kupera kana kupera.
Chikamu 6: Chikamu chePresentation
Chinangwa: Chinyorwa chepresentation chinotarisa nyaya dzekugadzirisa data, kusanganisira encryption uye decryption.
Kugadzirisa matambudziko:
○Pane dambudziko here nemutyairi kana software?
○Kana fomati yedata yakapatsanurwa nemazvo.
Chikamu 7: Chikamu Chekushandisa
Chinangwa: Chimiro chekushandisa chinopa masevhisi evashandisi zvakananga uye mapurogiramu akasiyana-siyana anoshanda pane ichi chikamu.
Kugadzirisa matambudziko:
○Chishandiso chacho chakagadzirwa nemazvo.
○Kana mushandisi ari kutevedzera nzira chaiyo yekuita.
Kusiyana kweTCP/IP modhi uye OSI modhi
Kunyangwe OSI model iriyo nzira yekutaurirana ne network, TCP/IP model ndiyo nzira inoshandiswa zvakanyanya ne network. TCP/IP model inoshandisa hierarchical structure, asi ine layers ina chete (application layer, transport layer, network layer, uye link layer), izvo zvinoenderana seizvi:
Chimiro chekushandisa cheOSI <--> Chimiro chekushandisa cheTCP/IP
Chigadziko chekufambisa cheOSI <--> Chigadziko chekufambisa cheTCP/IP
Rutivi rwenetwork rweOSI <--> Rutivi rwenetwork rweTCP/IP
Rutivi rwekubatanidza data reOSI uye rutivi rwemuviri <--> Rutivi rwekubatanidza rweTCP/IP
Saka, modhi yeOSI ine nhanho nomwe inopa gwara rakakosha rekushanda pamwe chete kwemidziyo yenetwork nemasisitimu nekuparadzanisa zvakajeka zvese zvine chekuita nekutaurirana kwenetwork. Kunzwisisa modhi iyi hakungobatsiri chete vatariri venetwork kugadzirisa matambudziko, asiwo kunoisa hwaro hwekudzidza nekutsvaga kwakadzama kwetekinoroji yenetwork. Ndinovimba kuti kuburikidza nesumo iyi, unogona kunzwisisa nekushandisa modhi yeOSI zvakadzama.
