2. Alternatives for Simple HSR Ring Topology Virtual QuadBox, ShortBox and HSR Mesh

3. 3-Port vs. 4-Port IED FRS (FPGA) CPU IED CPU FRS (FPGA) IED CPU FRS (FPGA) HSR RedBox 3/13

4. Topology of HSR 4/13

5. Potential problems with big rings 5/13

6. Quadbox 6/13

7. Virtual Quadbox 7/13

8. ShortCut Box 8/13

9. Virtual ShortBox 9/13

10. ShortBox 10/13

11. HSR Mesh 11/13

12. Conclusions  Other options besides a simple ring  More redundancy, lower latency  No additional devices needed if existing devices have an extra port  Flexibilis Redundant Switch (FRS) IP core has 3-8 ports  FRS has the HSR Mesh capability 12/13
