Benefits Of Satellite Nv System - Cisco ASR 9000 Series System Configuration Manual

Benefits of Satellite nV System

In general, the type of interface used on the host is decided on the basis of the satellite device used as shown
in the figure.
Both the 1-Gigabit Ethernet or 10-Gigabit Ethernet interfaces used as ICL are supported on the Cisco
Note
ASR 9000 Enhanced Ethernet line card and not on the Cisco ASR 9000 Ethernet line card.
Note When Cisco ASR 901 and Cisco ASR 903 are used as satellites, TDM interfaces cannot be used in the
Satellite nV System and RP redundancy on the chassis is not available.

This type of architecture can be realized in a carrier Ethernet transport network, with the satellite switches
used as either access switches, or pre-aggregation and aggregation switches. These switches feed into an edge
router, such as the Cisco ASR 9000 Series Router where more advanced Layer 2 and Layer 3 services are
provisioned. The network topology depicted in the figure is called the Hub and Spoke network topology.
You can also utilize this model in a Fiber To The Business (FTTB) network application, where business
internet and VPN services are offered on a commercial basis. Further, it can also be used in other networks,
such as wireless or Radio Access Network (RAN) backhaul aggregation networks.
Benefits of Satellite nV System
The Cisco ASR 9000 Series satellite nV system offers these benefits:
1 Extended port scalability and density - You can create a virtual line card with more than 400 physical
Gigabit Ethernet ports. There is a significant increase of Ethernet port density in the resulting logical Cisco
ASR 9000 Series Router. For example, a single 24-port Ten Gigabit Ethernet line card on the Cisco ASR
9000 Series Router could integrate up to 24 satellite switches each with 44 GigE ports; this results in an
effective port density of 1056 Gigabit Ethernet ports for each Cisco ASR 9000 Series Router line card
