Current Activities (E2E Performance WG)
piPEs-BR/GFD
• GFD = General Framework Design – Géant2/JRA1 Deliverable
• piPEs-BR/GFD is an architecture designed to provide
measurement information using Web Services in order to
interoperate with other network domains (eg. Internet2 and
Geant2).
• Some components have been designed and are being developed
to provided the Services specified in the GFD document (MP, MA,
LS, TopS, TS, RP).

Publish and Discovery Service (LS)
•
•
•
•
•
Uses UDDI technology
Development of a Lookup library
for the DPS
Adaptation of the DPS to work
with NMWG schema
Developed in JAVA
Interest in Multi-LS design and
testing

Test Manager (TM)
•
•
Will implement TopS and TS services
The idea with this component is to facilitate the visualization tool
development incorporating some functionalities such as:
– Data recovering
– Test scheduling
– Data composition
•
Topology Service – TopS
– It will store and provide topology information to users.
– It can have a software to “discover” the network topology and a specialized
database to store the topology information
•
Transformation Service – TS
– Aggregate, correlate or filter the data according to users needs.
– Also catch and store the measurement data to users avoiding new
connections and message sharing between users and other services.

piPEs-BR/GFD
Resource Protector (RP)
•
•
•
•
•
The first version will control the RNP´s MPs schedules in order to protect
network resources.
The initial resource to be protected will be link bandwidths.
The information about the MP schedules and required bandwidth will be
stored in a relational database.
The total consumed bandwidth per link for the desired time frame will be
compared with link capacities and the test will be authorized or not
depending on established policies (eg. Upper limit on link capacity
utilization and user data utilization).
Initially, only the services for MP tests control will be implemented.
