Abstract

A method may include provisioning: a first flow from a client-side port to a network-side port of the plug-in unit; a second flow from the network-side port to the client-side port; a third flow from the network-side port to a mate link configured to interface with a fourth flow from the mate link to a second client-side port of the second plug-in unit; a fifth flow from the mate link to the network-side port configured to interface with a sixth flow from the second client-side port to the mate link; a seventh flow from the client-side port to the mate link configured to interface with an eighth flow from the mate link to a second network-side port of the second plug-in unit; and a ninth flow from the mate link to the client-side port configured to interface with a tenth flow from the second network-side port to the mate link.

Dependent claims

A network element comprising:

a first plug-in unit comprising:
a first client-side port;
a first network-side port communicatively coupled to the first client-side port;
a first processor;
and
a first management module embodied in a computer-readable medium and configured to be read and executed by the first processor;
a second plug-in unit communicatively coupled to the first plug-in unit via a mate link, the second plug-in unit comprising:
a second client-side port;
a second network-side port communicatively coupled to the first client-side port;
a second processor;
and
a second management module embodied in a computer-readable medium and configured to be read and executed by the second processor;
wherein, the first management module is further configured to, when read and executed by the first processor, provision:
a first flow from the first client-side port to the first network-side port;
a second flow from the first network-side port to the first client-side port;
a third flow from the first network-side port to the mate link, the third flow configured to interface with a fourth flow from the mate link to the second client-side port;
a fifth flow from the mate link to the first network-side port, the fifth flow configured to interface with a sixth flow from the second client-side port to the mate link;
a seventh flow from the first client-side port to the mate link, the seventh flow configured to interface with an eighth flow from the mate link to the second network-side port;
and
a ninth flow from the mate link to the first client-side port, the ninth flow configured to interface with a tenth flow from the second network-side port to the mate link;
and
wherein, the second management module is further configured to, when read and executed by the second processor, provision:
the fourth flow;
the sixth flow;
the eighth flow;
the tenth flow;
an eleventh flow from the second client-side port to the second network-side port;
and
a twelfth flow from the second network-side port to the second client-side port.
