Hierarki Wide Area Network (WAN)

Core
• Fungsi
Menjadi Backbone jaringan yang bertanggung jawab pada traffic jaringan.

• Tugas
1. Mengatur Traffic keseluruhan yang besar dengan baik, cepat, dan handal
2. Menguasai traffic besar dan kecepatan jaringan perangkat

• Perangkat
Cisco Router 10000 Series

Cisco Nexus 7000 Switch, 9-10-18 slot (WAN use)

Distribution
Distribution Layer adalah titik pemisah (Demarcation Point) antara access layer dengan core layer dan membantu mendefinisikan dan membedakan core layer.

• Fungsi
Mengontrol traffic jaringan dengan pengawasan dan perencanaan broadcast domain dan mengelompokkan lalu lintas pada switch ke subnetwork yang terpisah

• Tugas
Menyediakan routing, filtering dan untuk menentukan cara terbaik utuk menangani permintaan layanan dakam jaringan

• Perangkat
Cisco ASR 1013 Router
o The Cisco ASR 1013 Router supports full-width card modules. It is designed with a single midplane with connectors on one interface midplane. The Cisco ASR 1013 Router supports:
o Up to 6 ASR1000-SIP40G shared port adapter modules
o Up to 24 shared port adapters (SPAs) and up to six SIPs
o Cisco ASR1000-ESP40
o Cisco ASR1000-RP2 router processor
o Quad power supplies (redundant pairs) by default; option of either AC or DC power supplies and two power supply zones. There are two power supplies for power zone 0 and two power supplies for power zone 1 (do not mix AC and DC power supplies).

Cisco Nexus 5010 Switch

o The Cisco Nexus 5010 Switch foundation is built upon:
-> High-performance 10 Gigabit Ethernet
-> IEEE Data Center Bridging (DCB) for lossless Ethernet
-> Fibre Channel over Ethernet (FCoE)
-> Virtual-machine-optimized networking
o The switch delivers more than 500 Gbps of switching capacity with 20 fixed wire-speed 10 Gigabit Ethernet ports that support data center bridging and FCoE. In addition, one expansion port supports one of the following modules:
-> 8-port 1/2/4 Gigabit Fibre Channel
-> 6-port 1/2/4/8 Gigabit Fibre Channel
-> 4-port 10 Gigabit Ethernet (DCB and FCoE) and 4-port 1/2/4 Gigabit Fibre Channel
-> 6-port 10 Gigabit Ethernet (DCB and FCoE)

Access

• Fungsi
Menyediakan sarana bagi user untuk mengakses jaringan WAN dan mengendalikan perangkat yang diijinkan mengakses.

• Tugas
1. Access Control dan policy yang diteruskan dari layer distribution
2. Collision domain terpisah
3. Konektivitas workgroup kedalam layer distribusi

• Perangkat
