Comparison Topology of World Research Network include INHERENT 2011
Alhamdulillah kabar baik mengenai INHERENT ditahun 2011 ini akhirnya muncul juga, setelah release informasi dari pihak kementrian pendidikan nasional dalam hal ini diwakili oleh pihak Pustekkom yang menyatakan bahwa awal April ini jaringan INHERENT (Indonesia Higher Education Network) akan diaktifkan kembali, konon kabarnya bahwa pemenang tender adalah Perusahaan Telekomunikasi BUMN raksasa di Negeri ini. Saat ini masih menunggu kabar dari Top Level Management kapan waktunya mulai eksekusi eskalasi jaringan ini di level Local Node(LN) hingga ke SublocalNode (SLN). Sembari menunggu kita lihat ke-Luar sejenak bagaimana jaringan Research seluruh Dunia berikut dengan topology yg mereka gunakan, termasuk INHERENT yg saya cintai ini.
The network topology of SINET3 has 63 edge nodes and 12 core nodes, i.e.,75 layer-1 switches and 12 IP/MPLS routers. The line speed between the edge and core nodes is 1 to 20 Gbps, and the backbone line speed between the core nodes is a maximum of 40 Gbps. The network deploys Japan’s first STM256(40Gbps) lines between Tokyo, Nagoya, and Osaka. The backbone links form three loops to enhance network resiliency natiomwide and to enable quick service recovery after network failures. The topology also enables efficient use of network bandwidth by sharing backbone links among users for all services.
In mainland China, there are 2,236 universities, 1.61 million teachers and staff, and over 20 million students in higher education. CERNET has 38 PoPs, backbone bandwidth has been up to multiple 10 Gbps and regional bandwidth up to 2.5 Gbps. There are about 1,500 universities and institutions connected and about 20 million end users.
The GEANT2 network, connects 34 countries through 30 national research and education networks (NRENs). Network design for GÉANT2 has focused on maximising operational and service flexibility. Handling the development of traffic patterns is crucial to the success of the network. The network architecture makes use of a flexible structure based on a combination of routed IP and switched components.
- All of the network’s 25 Points of Presence (PoPs) are fully equipped and in service.
- 43 of the network’s total of 44 routes are fully installed and operational, with just one of the 18 dark fibre routes still in preparation.
- The first links came into service in early December 2005, between Switzerland and Italy, and Switzerland and Germany, respectively. Multiple 10Gbps wavelengths are being employed in the network’s core.
Singapore Advanced Research and Education Network (SingAREN) is a non-profit organisation. We are Singapore’s national research and education network (REN) and part of the Internet2 community. We started as a national project funded by the government to take on the challenge of ensuring that Singapore’s Research and Education community is connected to the international community. SingAREN maintains close working relationship with the Next Generation Internet community such as Internet2, APAN (Asia Pacific Advanced Network), and RENs in various countries. SingAREN is to announce its partnership with GLORIAD ( Global Ring Network for Advanced Applications Development ) through the SingLight exchange point in Singapore for the GLORIAD-TAJ link. With this partnership, SingAREN’s international research and education network connectivity is now enhanced with a 1 Gbps link to USA and Europe.
