The Automated GOLE/SENSE Working Group within GNA-G is a worldwide collaboration of open exchange points and R&E networks to deliver network services end-to-end in a fully automated way, wherein connection requests are handled through the Network Service Interface Connection Service (NSI-CS).

An increasing number of networks across the globe is now using NSI to provision and deprovision international network services. This saves a considerable amount of time of NOC engineers facilitating international network service requests. Service creation is done within minutes, instead of multiple days or even weeks, removing manual human effort from the process.

Global R&E Network:
Connecting offshore students for international online education

With the onset of COVID-19, international students and staff from universities across the world have been unable to travel to return to campus from their home countries.  Many students remaining at home have experienced performance issues in reaching applications hosted in the cloud or on their home campus of the institution they’re studying at in another country.  A number of institutions around the world have negotiated solutions to this problem individually or as groups, including subscribing to Alibaba connection services or ensuring that cloud service providers such as Zoom have country-specific access.  NRENs have also endeavoured to assure sufficient bandwidth and peering capacity, for example better reach to Chinese internet destinations, however since the student traffic is typically from commodity internet sources in China, the traffic often may not touch the Global R&E Network (GREN).

In addition to the solutions found by individual universities, discussions are underway between CUCCIO/Canarie, UCISA/Jisc and CAUDIT/AARNet regarding possible national deals or services in those respective countries.

Goal of this Working Group:

The aim of this working-group is to investigate whether a collaborative international effort can deliver improvements in performance and/or lower costs for network connectivity to support teaching, learning and research for international users.  The initial case is China, but this requirement is truly international.

science Data Intensive Science

The GNA-G Data Intensive Science working group (DIS WG) is designed to provide a forum for discussion and a framework for both short term and longer term joint developments with the goal of meeting the needs of major programs in data intensive sciences, coexisting with the needs of individuals and smaller groups, while at the same time advancing the concepts, tools and systems needed to operate and manage the global ensemble of research and education networks while addressing the programs’ needs.

engineering Network Automation

This working-group will develop a catalogue of common network automation tools for use within a NREN to drive automated configuration, security auditing, change control activities and intra-domain automation activities.

For example, what CMDB, scripted provisioning tools, business process logic software and security auditing tools are used by each NREN?

The longer-term goal is to facilitate collaboration on common tools and practices, thus enabling NRENs to deploy network automation & orchestration more quickly and effectively.

The group will also work closely with other working groups to ensure interoperability and consistency.

  • Programmable Networks
  • Possibly others

Spawning a new working group

The process of creating a new working group within the GNA-G is lightweight:

1– a new working group is initiated by writing a draft charter that anyone may start;

2– the draft charter contains a detailed description of the proposed activity, its goal, milestones and proposed initial members;

3– The draft charter will then be discussed with the GNA-G Leadership Team and the Leadership Team decides starting the working group and appoints a ‘shepherd’ (liaison) from the Leadership Team. In case of green light, the new working group chair invites the members and commences work, based on the draft charter document.

While a working group is operational

  • Each working group has its own page on the GNA-G website and a mailinglist.
  • The working group chair reports on activities and milestones directly to the Leadership Team;
  • The working group chair updates the GNA-G members during online events and meetings;
  • Upon completion of work, inactivity or severe issues with obtaining goals, the Leadership Team may decide to stop a working group;
