Project Goals• Deploy “virtualizable” commercial routers

(Juniper m7i) in the ProtoGENI backbone that support commercial OS/software.

• Add software support to these virtual routers that will enable per-slice monitoring and measurement.

• Develop tools and interfaces that will allow slice users to use the measurement infrastructure in simple and easy ways.

Availability of Operational/Utilization Data

Infrastructure data: We have the ability to collect physical router data for network operations:Router/Link up/down statusLink utilization (#bits, #frames, #packets / second)CPU utilization Interface (link) error counters Interface packet loss/drop counters

Slice-specific dataSlice owner controls access to this dataMay be made available to network operations

Implementation of ShadowNet Component Manager

Based on ProtoGENI reference component managerTake the credential from any ProtoGENI certificate

authority

Add a module to handle all interactions with the Juniper routersUser provides RSpec to request logical routers being

createdAfter verifying the credential of the user, the

ShadowNet component manager will interact with Juniper routers and create a xml config file, which will be downloaded to Juniper routers via the netconf API.
