Beberapa Software Simulator/Emulator Yang Mendukung Konsep OpenFlow/SDN

Openflow adalah sebuah teknologi yang dapat melakukan kontrol terhadap switch sehingga data yang dikirim atau diterima dapat diatur sedemikian rupa sesuai dengan algoritma yang diimplementasikan pada hardware openflow (switch). Pada dasarnya sebuah device switch konvensional hanya beroperasi pada l2 dan l3, namun teknologi openflow memungkin switch dapat beroperasi pada layer l2 hingga l7. 

Untuk mengimplementasikan OpenFlow tentu membutuhkan switch yang mendukung teknologi tersebut, sebagai alternatif hardware kita dapat menggunakan beberapa software simulator/emulator yang beredar luas di internet:

1. Emulab
2. Estinet
3. Mininet
4. Ns-3

Pasang Microsoft Core fonts di OpenSUSE

Fonts-fonts yang sering kita jumpai pada sistem operasi windows, pada distribusi openSUSE tidak terinstall secara default. Hal ini disebabkan karena font tersebut merupakan proprietary fonts dan bisa jadi para pengembang openSUSE tidak menyertakan perangkat lunak yang dimiliki secara eksklusif oleh pihak tertentu idealis dan untuk penggunaan proprietary software berlaku hukum serta aturan tertentu.

Hal ini bisa menjadi kendala bagi pengguna linux khususnya openSUSE dalam menyusun artikel ataupun tulisan ilmiah, Penulis pun sempat mengalami kendala ketika sidang proposal karena font yang saya gunakan berbeda dengan font yang dipakai dalam panduan penulisan ilmiah dikampus, akibatnya bisa rame dibully rame2 pada proses sidang.
