Muchiitiko chaicho NPB yekunyora Packet kurasikirwa muNPB kunogona kukonzera iyo inotevera zviratidzo zviratidzo mumidziyo yekudzosera kumashure
- Alarm inogadzirwa kana iyo APM Service Service yekutarisa chiratidzo chinoderera, uye chiyero chekutengeserana chinoderera
- Iyo NPM network performance yekutarisa chiratidzo kunze kweiyo alarm inogadzirwa
- Iyo yekuchengetedza yekutarisa inokundikana kuona kurwiswa network nekuda kwekuita chiitiko
- Kurasikirwa kweBasa maitiro ekuongorora zviitiko zvinogadzirwa neiyo Service Audit system
... ...
Semukati mekutorwa kwekutora uye kugovera system yekubvisa bypass yekuona, kukosha kweNPB kunozviratidza. Panguva imwecheteyo, iyo nzira iyo data packet trac trac traffic yakasiyana neiyo tsika yerarama netekineti switch, uye tekinoroji yekudzora tarisiro yewakawanda service kurarama hazvishande kuNPB. Maitiro Ekugadzirisa NPB Packet kurasikirwa, ngatitange kubva kumidzi kukonzera kuongororwa kwekurasikirwa kwepaketi kuti ndione!
Npb / tinya packet kurasikirwa kugadzika midzi inokonzera kuongororwa
Chekutanga pane zvese, tinoongorora iyo chaiyo traffic nzira uye humbo hwepurure pakati pehurongwa uye huchiuya uye hunobuda hwemubatanidzwa 1 kana level npb network. Hazvina mhosva kuti rudzii rweteti network npb mafomu, seyakaunganidza system, pane akawanda-kune akawanda-kune-akawanda ekuisa traffic yekuisa pakati pe "kuwana" uye "kuburitsa" kwehurongwa hwese.
Ipapo tinotarisa kune bhizinesi muenzaniso weNPB kubva pamaonero eAsic Chips pane imwe chete kifaa:
Chimiro 1. Mune yakajairika yakawanda-kune-imwe kana yakawanda-kune-yakawanda-yakawanda traffic acgregation mamiriro, huwandu hwenzvimbo yekubuda kwenguva inowanzoita madiki pane huwandu hwenhamba yekuisa. Semuenzaniso, gumi zviteshi zve 10G kuunganidza uye 1 chiteshi che 10G kubuda; Muchikamu chemultilevel
Feature 2: Asic chip cache zviwanikwa zvakaderera. Panyaya yeiyo parizvino inoshandiswa A 3.2TBPS Capacity Chip ine cache ye20-50 mbytes. Kusanganisira broundcom, isina shangu, ctc, marvell uye vamwe vagadziri veAsic machipisi.
Feature 3. Iyo CORE yePFC FLOCK Control mechanism ndeyekupedzisira kuguma kwekupedzisira kudzora mhinduro, uye pakupedzisira kuderedza kutumira mapaketi ekutaurirana kwekutaurirana kuderedza kuderedza kuderera. Nekudaro, iyo packet sosi yeNPB masevhisi ane makagireni emakaricha, saka zano rekugadzirisa racho rinogona chete kuraswa kana kutamaniswa.
Izvi zvinotevera kutaridzika kwemazvo micro-kuputika pane inoyerera curve:
Kutora 10G interface semuenzaniso, mune yechipiri level traffic traffic trend qualissis diagram, iyo traffic traffic inochengetwa pane anenge 3Gbps kwenguva yakareba. PaMicro Millisecond Trend Ongorora Chati, Traffic Spike (Microbubrst) yakadarika kwazvo 10G interface yemuviri.
Key Techniques yekudzora NPB Microbust
Kuderedza kukanganiswa kweAsymmetric yenyama yemhando yerudzi rwemitambo mismatch- Kana uchigadzira network, kuderedza asymmetric yekuisa uye yekubuda mumuviri yemukati meretface huwandu zvakanyanya sezvinobvira. Nzira yakajairika ndeyekushandisa iyo yakakwira chiyero uplink yekubatanidza chinongedzo, uye dzivirira asymmetric yemukati yemari yemari (semuenzaniso, kutevedzera 1 gbit / s traffic panguva imwe chete).
Simbisa iyo cache manejimendi mutemo weiyo NPB service- Iyo yakajairika cache manejimendi mutemo inoshanda kune iyo switching service haina kushanda kune iyo yekuendesa kufambidzana kweiyo NPB service. Iyo cache manejimendi mutemo weiyo static guarantee + Dynamic kugoverwa kunofanirwa kuitwa zvichienderana nezvinhu zveNPB service. Kuti uderedze kukanganiswa kweNPB microbust pasi peiyo chiripo chip hardware mamiriro ekunze.
Kuita Screen Smicali Injiniya Management-Kushandisa kukoshesa kwekutanga kweinjineti yeInternet Service manejimendi zvichienderana neTraffic kuiswa. Ita shuwa hunhu hwebasa remhando dzakasiyana dzekutangira pamatanho eQueue Bandwidths, uye ita kuti mushandisi anonzwa service traffic mapaketi anogona kutumirwa pasina kuparadzirwa.
Iyo Spection System Solution inowedzera iyo packet yekukwana kugona uye traffic kuyambuka kugona-Kunhudzai mhinduro kuburikidza zvakasiyana-siyana nzira yekuwedzera iyo packet caching caping yekukwanisa kweiyo yeAsic chip. Nekugadzira kuyerera kwenzvimbo dzakasiyana, iyo micro-inoputika inova micro-yunifomu kuyerera kuparara mushure mekuumba.
MyLinking ™ micro bust traffic trailes management Solution
Scheme 1 - Network-Optimized Cache Management Strategy + Network-Wide Clartified Service Mhando Yekutanga Management
Cache Management Strategy yakagadziriswa kune iyo netiweki yese
Zvichienderana nekunzwisisa kwakadzama kweNPB Service maitiro uye anoshanda ebhizinesi ehuwandu hwehuwandu hwe "NPB Cache Iyo microbuburst kusimba kunoonekwa kusvika kune huwandu hwepamusoro kana iyo yazvino Aicic chip cache yakagadziriswa.
Microbucst Kugadzirisa Technology - Management zvichibva pane zvebhizinesi zvekutanga
Kana iyo traffic yekutora yatove yakaiswa yakazvimirira, inogona zvakare kutungamirwa zvichienderana nekukosha kweiyo yekudzosera-yekuongorora chishandiso kana kukosha kwedata rebasa racho pacharo. Semuenzaniso, pakati pezvakawanda zvekuongorora zvishandiso, APM / BPC inokoshesa kukurumidza kuongorora Naizvozvo, nekuda kwezviitiko izvi, iyo data inodikanwa neAPM / BPC inogona kutsanangurwa seyakanyanya kutarisisa, iyo data yekuongorora inogona kutsanangurwa Pakapetwa mateji e data ikaisa Pinda yekupinda, zvinhu zvinotsanangurwa zvichienderana nekukosha kwemapaketi. Mapaketi ezvekutanga anokoshesa kutungamirirwa mushure mekunge mapaketi epamusoro anotenderwa anotumirwa, uye mapakeki ezvimwe zvekutanga anotumirwa mushure mekutongwa kwepamusoro pekutanga kuendeswa. Kana mapaketi ezvekutanga kukoshesa anoenderera mberi kusvika, mapaketi ezvakakwirira zvekutanga zvinotarisirwa. Kana iyo data yekuisa inodarika kukosha kwekutumira kweiyo yekubuda kwechiteshi kwenguva yakareba, iyo yakawandisa data inochengeterwa mucheki yemushini. Kana iyo cache izere, chishandiso chakasarudzika kurasa mapaketi ezvikamu zvakaderera. Iyi inokatyamadza manejimendi manejimendi inovimbisa kuti zvishandiso zvakakosha zvinogona kuwana iyo data yekutanga yemigwagwa inodiwa pakuongororwa munguva chaiyo.
Microbust kugadzirisa tekinoroji - Classificification Guarantee Mechanism yeiyo yakazara network service yemhando yepamusoro
Sezvinoratidzwa neyekutanga chifananidzo, trafficifiti yekubatanidza tekinoroji inoshandiswa kusiyanisa masevhisi akasiyana pane zvese zvishandiso paCoction Iyo SDN Controller inoburitsa iyo Yekutanga Yekutanga Policity System nenzira yepakati uye inoigadzirisa kune zvishandiso zvekutumira. Midziyo yese iri kutora chikamu mumasikjeri ari kusekerera kune akasiyana-siyana ekutanga mabvumirano maererano nezvakatumirwa zvakatakurwa nemapaketi. Nenzira iyi, madiki-traffic adanced pregers ekutanga kunogona kuwana zero packet kurasikirwa. Njodzi inogadzirisa iyo packet kurasikirwa dambudziko rekutarisa kweAppred
Solution 2 - GB-Level Expression System Cache + Traffic Sping Scheme
GB Level system yakawedzera cache
Kana chishandiso cheyunivhesiti yedu yekuwana yekukwana basa Kuti uwane imwe chete yekuwana mudziyo, zvirinani GB kugona kunogona kupihwa se cache nzvimbo yeiyo danho rekutora. Iyi tekinoroji inogadzira iyo buffer kugona kweyedu traffic yekutora mari yemazana enguva dzakakwirira kupfuura iyo yeiyo yetsika yekuwana yechinyakare. Pasi pemhando imwechete yekuendesa mberi, iyo yakakwira micro bust Iyo millisecond level inotsigirwa neyechinyakare yekuwana michina yakakwidziridzwa kune yechipiri nhanho, uye nguva yakapururudzwa-iyo inogona kutsungirira nezviuru zvenguva.
Multi-Queue traffic kugovera kugona
Microbust kugadzirisa tekinoroji - mhinduro yakavakirwa pane yakakura buffer caching + traffic kuumbwa
Neine super-buffer yekugona, iyo traffic data yakagadzirwa neiyo micro-inoputika yakamanikidzwa, uye tekinoroji yekuvandudza traffic inoshandiswa mune inobuda muzvikamu zvekubuda mumapaketi ekuongorora. Kuburikidza nekushandiswa kwehunyanzvi uhwu, kuraswa kwepakukiti chiitiko chinokonzerwa ne micro-kuputika kwakagadziriswa.
