馬嘶的網路大道

才說網路攻城獅喜歡CLI, C就搞一個用GUI管網路的架構（API也可啦) 看完packet flow, 只能說一堆疑問, 真要除錯(沒有不出錯的盒子), 要有 debug command吧  ,

http://ethancbanks.com/2014/10/16/cisco-aci-fabric-forwarding-in-a-nutshell/ 開始讀ACI, 我以為是像NSX類似的架構. 至少還是網路咖可以理解的 範圍, 我錯了, 沒什麼 routing/switching的東西， 這一個矩陣就可看做一個 交換機, 裡面怎麼跑不要你管,  用就是了

L2 交換這件事又讓我嚇一跳, 原來vPC/MCT/MC-LAG/MLAG是被拿來 幹L2的multipath多路徑 果然不能只聽一家之言, 這招看來是最普遍的(也最XX) 還有一堆技術 L2的 -TRILL ( fabricpath , VCS) -SPB (PBB變種) -SPB+ -IRF - stacking(專屬) -802.1BR port extender L3 - 把bgp routing/EVPN請進data center來

就是看著一半的容量不用很難過

MPLS in the SDN Era Interoperable Scenarios to Make Networks Scale to New Services 雖說算是我的專長,  但這題目, 有點傷感 誰在SDN時代還提MPLS呢 不過, 我還是要讀 好像懷舊歌曲一般

如果你不想玩ovs 或 mininet的話 但是,我現在就有玩不完的阿 http://northboundnetworks.com/products/zodiac-fx?utm_content=bufferbcc42&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer

https://globalnoc.iu.edu/sdn/scipass.html 原先Science DMZ的概念就是把科研與一般上網服務的流量隔離 其實就是避開L4-7設備的瓶頸, Scipass引入SDN的概念, 將分析後的 智能反饋回網路控制 一如SDN的進展,  現在只是剛開始而已 當然有時間差 , 但是網路速度和 L4-7設備的進展(當然和價位有關, 100G的 IPS要多少錢)落差只會越來越大 , 立即攔下威脅的好處和可能性也越來越低了

威脅是真的 但客戶還是只能用嚇的 除非要當很專的malware研究員 不然就別看組合語言的相關內容了 知道原理就好了 知道了也不會用的更好 安全大多只是信心罷了 廣度雜度是必備的 OS  protocols authentication,  就一個active directory就可以把你玩死 ......

明明是網路設備業者的大肥羊 偏偏都選擇自己來 更可怕的是玩的還比你好很多 反到是你得向他拜師學藝 http://www.nextplatform.com/2015/06/23/bringing-hyperscale-sdn-lessons-down-to-enterprises/ https://www.sdxcentral.com/articles/news/hyperscale-white-box-switches-prepare-to-be-shocked/2015/04/
