Topics in my writing backlog:
- How internet really works?
- Distributed systems in networking box
- Why C language is still exists and its competitor
- How do you measure your impact on the industry?
- Google’s Network Overview - Data Center(Jupiter), Backbone(B4), Control Plane(Orion), SDN controller for Google’s peering edge network(Espresso), Load Balancer(Maglev)
- Google’s data center network infrastructure:
- Jupiter Fabric: This is the internal network within Google’s data centers, operating at speeds of 40 Gbps per link and capable of handling a total bandwidth of 1 Petabit per second (Pbps). It leverages Software-Defined Networking (SDN) for centralized control and management.
- WAN B4: This is Google’s wide-area network (WAN) that connects its data centers globally. It also utilizes SDN for efficient traffic routing and boasts high throughput in the terabit range (Tbps).
- B2: This network segment connects Google’s data centers to the global internet backbone with very high Service Level Agreements (SLAs) for guaranteed performance and reliability for user-facing traffic entering the Google network
- Espresso: This is the SDN controller for Google’s peering edge network. It dynamically selects the most efficient routes to deliver customer traffic based on real-time measurements of availability and latency.
- Orion: This is the SDN platform deployed across both Jupiter fabrics and the WAN B4 network for Google’s entire network, not just GCP. It acts as the central control point for provisioning, configuring, and managing network resources.it acts as the control plane, telling the network equipment (switches, routers) how to route traffic and manage overall network behavior. Think of Orion as the central traffic control system, directing data flow across the entire Google network.
- Andromeda: This is the SDN platform focuses on network virtualization. It’s an internal system within Google Cloud Platform (GCP) that creates and manages virtual networks on top of the physical network infrastructure. Imagine it as carving out dedicated virtual highways within a massive physical road network for GCP users.
