🔷 Polycube: Open-Source Network Framework 🔗
Polycube is an open-source software framework that provides fast and lightweight network functions such as:
- Bridges
- Routers
- Firewalls
- Other network services
Polycube services, called cubes, can be composed to build arbitrary service chains, enabling custom network connectivity for:
- Namespaces
- Containers
- Virtual machines (VMs)
- Physical hosts
🛠 My Work in Brief 🔗
📊 Introducing Custom Metrics 🔗
I focused on implementing custom metrics, defined in the YANG model of each service. These metrics are collected and exposed via the /metrics endpoint, which is later read by Prometheus.
Example metric:
- How many IP addresses are set in the routing table of a given router (e.g.,
R1).
🚀 Technologies & Skills Gained 🔗
During this work, I gained expertise in:
- Observability: Prometheus, Grafana
- Networking & Frameworks: Polycube, YANG, eBPF
- Programming: Improved C++ skills, using:
prometheus-cpp(for Prometheus integration)jsoncons(for JSON handling)
- Containerization & Scripting: Docker, Bash, REST APIs
