Methods and apparatus for monetizing a carrier network are provided. In an example, a wavelength service is captured from deployed network assets in a carrier network. A revenue factor (R), a capital expenditure factor (C), an operational expenditure factor (O), and a service level agreement factor (S) are selected from an analytic profile of the carrier network based on the wavelength service requirements. The R, C, O, and S factors are hexadecimal numbers, and can be weighted relative to each other. An index is calculated by concatenating the R, C, O, and S factors a prioritized order and converting the resultant hexadecimal number into a decimal number. The calculated index is assigned to the wavelength service. The index can be displayed, along with indices for other wavelengths on other paths, to a user in a graphical form.

A network interface card (NIC) and a method for stablishing a connection between virtual machines of a network. The NIC includes: a programmable switching ASIC (application-specific integrated circuit), a central processing unit (CPU), multiple Ethernet controllers, and multiple on-board transceivers functioning as external ports. The switching ASIC functions as a switch that manipulates data traffic within the NIC including by switching the data traffic between and among the CPU, the Ethernet controllers, and the on-board transceivers. The method includes: installing rules that route a Synchronize (SYN) packet from a source virtual machine (VM) through a software engine, appending a signed cookie to the SYN packet; verifying that a policy represented by the signed cookie appended to the SYN packet matches a policy of a destination VM; and returning the SYN packet to the source VM which establishes a connection between the source VM and the destination VM.

Implementations described and claimed herein provide systems and methods for a configurable optical peering fabric to dynamically create a connection between participant sites without any physical site limitations or necessity of specialized client and network provider equipment being located within such a facility. Client sites to a network may connect to a configurable switching element to be interconnected to other client sites in response to a request to connect the first client site with a second site, also connected to network, via the switching element. A request may trigger verification of the requested and, upon validation, transmission of an instruction to the switching element to enable the cross connect within the switching element. The first site and the second site may thus be interconnected via the switching element in response to the request, without the need to co-locate equipment or to manually install a jumper between client equipment.
