Virtualization Increases Utilization

Before Virtualization

Virtualization enables consolidation of workloads from underutilized

servers onto a single server to safely achieve higher utilization

from existing Multicast flows.No packet loss

MPLS Configuration Only Relies on NSF/GR for hitless transition. Tables remain active on line cards so forward never

Multi-Active Detection (MAD)IRF runs between two or more core devices (example S10500)Heartbeats handled by secondary CPU (usually 10ms heartbeats) to trigger failure

• LACP (802.3ad)Hash handled at the ASIC layer for traffic distribution independent from peer device – Requires HPN Switches Today

• BFD (Bi directional Forwarding Detection)Dedicated Link Between Units

• ARPLeverages Gratuitous ARP packets that convey active IRF IDs. Used in conjunction with MSTP on intermediate device

• ND (Neighbor Discovery) for IPv6Leverages the Neighbor Discovery (ND) portion of the NS protocol for IPv6 Used in conjunction with MSTP on intermediate device
