Description Telecommunication providers are currently very interested in allowing the management of Service Level Agreements (SLA) with their internal and external customers. This interest is stimulating research for improving the technical solutions that allow performance monitoring of IP networks.
At the same time, telecommunication providers are progressively moving their infrastructures towards intensive use of Network Function Virtualization (NFV) and data centers. The current trend is to provide services to clients through data centers using this approach.
This thesis proposal is about performance monitoring in virtualized network environments. The final aim is to realize a virtual performance monitoring system that can monitor the performance of the connections among different data centers, each one providing virtualized services. According to this approach, the monitoring system will be itself implemented as a collection of virtual network services hosted in the same data centers that are monitored. As these services are expected to have very high performance and low overhead, they will be developed using a new approach which consists of implementing the virtual monitoring functions as eBPF programs running in the Linux kernel, making use of the IOVisor technique.
The thesis will be done in collaboration with Telecom Italia (TIM) and part of the work will be done in Telecom Italia premises (TIlab). As Telecom Italia is currently creating a number of data centers, the prototype developed in the thesis will be experimented in these data centers. The monitoring algorithm will be based on the PNPM SLA technique (see IETF draft “draft-fioccola-ippm-rfc6812-alt-mark-ext”), for which a C implementation already exists. This implementation has to be turned into a virtual network function, using the approach described above, and deployed in the Telecom Italia data centers. Performance and scalability tuning will complete the work.
A prize of 4000 euros will be made available if good quality results are achieved.
The thesis is a good opportunity to learn about NFV and to get in touch with TIM.
