Embodiment Construction

[0015] figure 1 is a schematic illustration of a multi-layer network employing a multi-layer network translation interface module (eg, controller-to-controller interface 112a or 112b ), according to one embodiment. In some implementations, a multi-tier network may include network nodes 102 , 104 and 106 . Each network node 102, 104, and 106 may be a network device including, but not limited to, a network switch, network router, network storage device, network access device, and / or similar network computing device. Each network node may include at least one memory and a processor and / or a set of processors, and may be configured to store processor-executable instructions in the memory to perform various functions in the network.

[0016] In some implementations, the network nodes 102, 104, and 106 may be operatively coupled to a network entity, such as a server layer controller 108 at a second layer of a multi-layer network (e.g., including, but not limited to, the data link l...

Abstract

The present invention relates to a controller-to-controller interface for multi-layer network abstraction. Specifically, a controller at an IP (eg, client) in a multi-tier network may request a network topology map from another controller at the optical (eg, server) layer in the multi-tier network. The controller at the optical layer of the network can use the layer mapping function and common properties between the formats used to describe the network topology map at the two layers to generate a representation of the network topology stored at the controller at the optical layer of the network A common layer abstraction model for graphs. The controller-to-controller interface can translate and / or send the common layer abstraction model to the controller at the IP layer for processing data on the network.

Description

technical field [0001] Certain embodiments described herein relate generally to networking systems, and more specifically, to systems and methods for abstracting the layers of a multilayer network. Background technique [0002] Multi-layer networks have been widely used as one of many different ways of organizing network resources to describe different network functionalities and / or purposes. Each layer (also referred to herein as a domain) in the network may use different underlying technologies, which are not necessarily inherently compatible with each other. For example, the optical network layer and the IP network layer often use different communication protocols, represent links between network devices differently, be controlled differently, and so on. [0003] Known networks have historically used a shared cross-layer format for the optical network layer and the IP network layer to represent links between network devices and / or similar network attributes. For example...
