Product Specifications

Technical details and manufacturing context for Switch Fabric

Definition
A switch fabric is the core hardware component of a network switch responsible for directing data packets between input and output ports at high speeds. It functions as the internal switching matrix that enables simultaneous, non-blocking communication between multiple ports, determining the switch's overall forwarding capacity and performance.
Working Principle
The fabric receives data packets from ingress ports, examines header information (like MAC or IP addresses), makes forwarding decisions based on a forwarding table, and routes the packets through an internal high-speed interconnect (often a crossbar, shared memory, or multi-stage switching architecture) to the appropriate egress ports. It manages traffic flow, prioritization, and congestion to ensure efficient data transfer.
Common Materials
Semiconductor (Silicon), Printed Circuit Board (PCB), Copper traces/interconnects
Technical Parameters
  • Aggregate switching bandwidth or backplane capacity, indicating the total maximum data throughput the fabric can handle simultaneously. (Gbps) Per Request
Components / BOM
  • Crossbar Switch Matrix
    Provides direct, simultaneous point-to-point connections between multiple inputs and outputs, enabling non-blocking switching.
    Material: Semiconductor circuits on silicon
  • Shared Memory Buffer
    Temporarily stores incoming packets while forwarding decisions are made, managing congestion and packet queuing.
    Material: Semiconductor memory (e.g., SRAM, DRAM)
  • Arbiter/Scheduler
    Controls access to the fabric resources, resolving conflicts when multiple inputs request the same output port simultaneously.
    Material: Semiconductor logic circuits
