Project Goals

There are two primary goals of our project:

1.Network Extension

Extend the existing 10 gigabit open source research

network between KTH Kista and Valhallavägen to

Karolinska in Solna and Huddinge

2. Network Operation Centre

Implement a Network Operation Center (NOC) to monitor

the network performance, devices and make it secure

Slide # 3

Project Background Extension of Previous CSD projects working on HD Video

Conferencing including:

CUinHD, CSD Spring 2009

HDValley, CSD Fall 2008

High Definition Video Conferencing System needs a high

performance and fault tolerant underlying network

HDviaOSN Network Group has put its effort to build this

network

Alternative Scheme: Install 70km 1G SFPs to get the link up and change the network cards to 10G once

the fiber is replace

Network GraphingMRTG

 Tool to monitor the traffic load on network links

Generates HTML pages containing PNG images

Uses SNMP to read the traffic Counters of the devices and Create graphs

Slide # 16

Network GraphingCacticomplete network graphing solution

Provides an easy to use web Interface for configuration

Stores all of the necessary information to create graphs and populate them with data in a MySQL database

We are monitoring CPU load, Memory usage and Bifrost Routerswith the help of Cacti

KI Bifrost

KTH Valhallavagen

Fiber Link

Total Attenuation 20-22dB

Expected Total Attenuation after new fiber is installed: 16 + 0.5 = 16.6 dB

Acceptable Attenuation for 1550nm XFPs = 19 dB

Link Budget Margin = 19- 16.5 = 2.5 dB

2.5 dB is good but

not suitable for long

term solution

Slide # 27

Future Work- Network ExtensionOption 2 Install a bifrost router in Karolinska Solna which will be suitable for long term solution and video conferencing can be performed from Solna as well.

Slide # 28

Future WorkBifrost Routing Performance

It’s a continuous process to be carried on to boost the

performance further with new equipments, Documentation on

our website will be helpful

NOC System

Evaluate and implement a mechanism for monitoring the live

HD video streams for HD video conferencing system

Maputo Network

Deploy similar network and NOC system in Mozambique NREN,

as the MoRENet starts operating
