Leased-Line Aggregation—General
The Cisco 10000 Series has provided leased-line aggregation services for tens of thousands of business customers and
hundreds of carriers (Figure 6). The provider edge is the dividing line between the various access technologies and
networks used to present customer connections to the carrier and the core IP transport network used for Internet or
VPN connectivity.

and IP routing, along with many IP services.
Baseline Attributes for the Cisco 10000 Series Leased-Line Aggregator
Interface diversity and density—Offers one of the broadest ranges of physical and logical interfaces in the industry,
from low-speed copper to high-speed optical channelized. All major worldwide interfaces are supported, enabling
the global service provider to select a single product for worldwide deployments. Using high-speed channelized
interfaces, the Cisco 10000 Series is able to boast the highest interface densities in the industry.
High-performance IP services—Using the Cisco 10000 Series PXF adaptive processing architecture, the range of IP
services continues to expand as the product and market matures. The Cisco 1000 Series Performance Routing Engine
(PRE-2) expands the Cisco 10000 Series link efficiency mechanisms to include Multilink Frame Relay, and many
other IP services have been enhanced over the PRE-1 implementation.
Rich MPLS feature set—Many service providers are deploying VPN-based solutions for additional revenue growth
in 2003 and beyond. The Cisco 10000 Series has proven its versatility, performance, and availability as a
next-generation provider edge router. The PRE-2/Full Sail release builds on this feature set to expand and increase
performance in this important application space
