Cloud Facility

Route Control: Transit Portal (TP)

• Give each service the illusion of its own upstream connectivity– Custom routes and ISPs – Sharing of numbered

resources– Shared colocation and

connectivity– Single contract with

upstream ISPs• Amortizes costs of

upstream connectivity.2

Accomplishments 1: Advancing GENI Spiral 2 Goals

• Educational aspects of BGP Mux– Integrated BGP Mux into coursework– Problem Set posted and completed– Nine groups successfully completed– Integrating into graduate course this fall

• BGP Mux software release• EGRE tunnel and node instantiation software release.• Deployment of BGP sessions in three locations• Demonstatrions at every GEC• Integration with OpenFlow-based campus network• Resource manager to be demonstrated at GEC 9

Issues

• Still waiting on IP address space. Cannot support more than 8 experiments without more address space.

• Integration with Emulab is difficult because we do not have the resources to pay an additional programmer to work with that team. – Solution: They should take our reference manager and figure out

how to integrate it.

• Acquiring more deployment sites is practically a full-time job because it requires following through with operators.

Plans

• Better integration with experimental environments (e.g., GENI, CoreLab)

• Better interface to wide-area route control– BGP might be too complicated or heavyweight for many

applications

• Possible extensions– Back-haul between cloud facilities– IP prefix sharing

• More deployment sites
