Distributed Core

VCStack LD (Long Distance) enables the

VCStack solution to provide a distributed

network core. The increased distance

provided by ber stacking connectivity

means that members of the virtual

chassis do not need to be co-located.

Instead, they can be kilometers apart.

Diagram 1 shows an example of a long

distance stack, where the single virtual

distributed core ensures high availability

of data for network users.

Network Virtualization

Virtual Routing and Forwarding (VRF

Lite) allows multiple customers to

share a common infrastructure, while

maintaining their own independent

virtual routing domains. Individual

customers can take advantage of

shared resources such as printers and

Internet access via ltered inter-VRF

communication, while maintaining

absolute security. See diagram 2.
