Chapter 3 Cisco SCE 8000 Topology and Topology-Related Parameters
Multi-Gigabit Service Control Platform (MGSCP) Topology
• N+1
'N' SCE platforms are active and one platform is on standby. The EC ports connected to the standby
SCE platform must be configured as standby ports. In the case of failure of one of the SCE
platforms, the EC ports connected to the failing SCE platform are shut, and the standby EC ports
that are connected to the standby SCE platform are activated.
Because the Cisco SCE 8000 supports two links, this configuration requires one SCE platform per
two links (two EC ports), plus one extra SCE platform for standby.
The standby SCE platform must be connected to the two highest-numbered ports, because EC
behavior automatically designates these as the standby ports.
Redundant Cisco 7600 Series Router
Two Cisco 7600 Series routers can be used to provide network redundancy (see Figure 3-8).
In this topology, one link on each Cisco SCE 8000 platform is connected to each router. Therefore, one
SCE platform is required for each link.
