Cisco Cisco MGX-FRSM-HS2 B Serial Frame Service Module Fascicule

Solution Overview

The primary benefits of this logical grouping include the following:

●

Increased operational efficiency of a simplified network using virtualization

●

Increased availability and forwarding performance through interchassis stateful switchover (SSO) and

nonstop forwarding (NSF)

●

Increased availability and forwarding performance through MEC

The VSS will be used as a Layer 3 isolated service block with the following flexibility advantages:

●

Reduced topology complexity: loop free

●

Service module integration

●

Up to 50 percent reduction in packet hopping between the routing node and the service node

Cisco ACE is inserted in the VSS as a service module. Cisco ACE supports a variety of topologies: routed mode,

bridge mode, one-armed mode, etc. In the solution shown in Figure 7, Cisco ACE is used in a one-armed mode

topology. The one-armed Cisco ACE can be introduced transparently into the network and will not be in the path of

other traffic that does not need to go to the virtual IP addresses. Cisco ACE failure or failover affects only traffic that

is being load-balanced or that uses other Cisco ACE application services such as SSL acceleration. A traffic-

diversion mechanism is required to help ensure that both sides of a protocol exchange pass through the Cisco ACE;

either Policy-Based Routing (PBR) or Source-Address Network Address Translation (Source-NAT) may be used.

Source-NAT is recommended in this solution.

Conclusion

Multi-tenancy is a crucial requirement for scalable, reliable, and cost-effective application delivery and infrastructure

services in the data center. Enterprises and service providers alike can reap significant cost reduction and

application deployment acceleration benefits with the Cisco ACE Module and Cisco ACE 4710 appliance. Cisco ACE

is the only solution on the market today that provides true application delivery virtualization capabilities. Cisco Nexus

7000 Series VDCs offer a great amount of flexibility with design options to optimize the use of existing or new data

center space. With facility resources quickly becoming limiting factors in overall design scalability, having additional

tools available to increase utilization while being able to preserve operations and service delivery organizational

structure is critical. VDCs on the Cisco Nexus 7000 Series are a critical feature that offers these benefits to the

network architect and engineer while remaining transparent to operations.
