Single System Multiple Interface Solution; Full Feature Internal Service Cross Connect Solution - Alcatel-Lucent 7750 SR Manual

Single System Multiple Interface Solution

The single system solution retains the same SLA enforcement and accounting capabilities as the
multiple system solution but with the advantage of only requiring a single chassis. This is
accomplished by defining the VPLS and IES services on different physical interfaces of the same
type. Both interfaces are defined as access types and use the same encapsulation type (i.e., Dot1q).
The services are configured with the same encapsulation values and the physical interfaces are
interconnected using an external jumper cable. To avoid single point of failure issues, Link
Aggregation Groups (LAG) can be used to provide an N-to-1 redundancy mechanism (as well as
adding more interconnect bandwidth).

Full Feature Internal Service Cross Connect Solution

The internal service cross connect solution provides similar functionality as the single system
multiple interface solution while attempting to minimize the cost, density and provisioning issues
inherent to the external port jumper method. The internal service cross connection feature uses
new service provisioning objects and a new type of hardware adapter to manage internal service
cross connections. The remainder of this document describes the internal service cross connection
feature.
