Problems solved by technology

There are also issues related to isolating cloud resources from malicious attacks and ensuring that connections to cloud network resources do not compromise internal network infrastructure
Additionally, customers may face increased complexity in dealing with different sets of on-premises and cloud resources rather than resources from two equivalent locations

Embodiment Construction

[0023] Referring now to the drawings, wherein like numerals refer to like components or steps, there are broad aspects of the various exemplary embodiments disclosed.

[0024] figure 1 is a schematic diagram of an exemplary network 100 for extending a private enterprise network to a cloud topology. In various exemplary embodiments, network 100 includes: private enterprise network 101, service provider network 102, cloud network 103, customer edge (CE) devices 110a-h, provider edge devices 111a-h, cloud data center CE 112. Data center interconnect 113 and servers 114a-d each housing a hypervisor 115a-d and a virtual machine 116a-d.

[0025] Each of private enterprise network 101, service provider network 102, and cloud network 103 may be a packet-switched network. Such a packet-switched network may be any network that operates according to a packet-based protocol. Thus, each of the networks 101, 102, 103 may operate according to, for example, Transmission Control Protocol / In...

Abstract

Various embodiments relate to a Cloud Data Center, a system comprising the Cloud Data Center, and a related method. The Cloud Data Center may include a logical customer edge router to send packets between addresses in a private enterprise network and addresses in a logical network within a cloud network. The logical network may have resources, known as virtual machines, allocated to the private enterprise network and may share a common IP address space with the private enterprise network. A directory at the Cloud Data Center may correlate the enterprise IP addresses of virtual machines with a cloud IP address and a location IP address within the logical network. The Cloud Data Center may double encapsulate packets with two specified headers, a cloudIP and locIP header, when sending a packet to a destination in the logical network.

Description

technical field [0001] Embodiments disclosed herein relate generally to network infrastructure and Internet communications. Background technique [0002] Cloud computing networking is a highly scalable and dynamic service that allows cloud computing providers to provide resources to customers over the Internet. The cloud infrastructure provides an abstraction layer such that the client does not need to know the specific infrastructure in the cloud that provides the requested resource. This service helps customers avoid the capital expense of additional hardware for peak use, as customers can use additional resources in the cloud for heavy loads, and use infrastructure already in place on private enterprise networks for day-to-day use. [0003] For example, systems such as Infrastructure as a Service (IaaS), which allow customers to run their own computer applications on rented computers. Such a system allows for scalable deployment of resources, where customers create virt...
