IP multicast service join process for MPLS-based virtual private cloud networking

Abstract

A multicast cloud controller (“MCC”) in a cloud system implements a process to manage multicast traffic in a cloud network. The MCC is coupled to at least one virtualized server for hosting one or more virtual machines (“VM”), wherein the virtualized server comprises at least one virtual switch (“VS”) that supports multiprotocol label switching (MPLS) and the virtual switch is coupled to a top of rack switch (“TORS”) that supports MPLS. MPLS is utilized to support multicast data traffic in the cloud system such that the system and method reduces state and is scalable.

Description

technical field [0001] Embodiments of the present invention relate to the field of cloud computing; and more particularly, to multicast support in cloud computing. Background technique [0002] Large corporations have been concentrating on their computing resources in data centers for many years. This trend has accelerated over the past few years as server virtualization technology has become more common. As data centers became larger, some data center operators began to provide computing, storage and network communication resources to external customers, who then became tenants of the data center. The offered service typically consists of elastic, on-demand processing storage, which for most practical purposes is limited only by the customer's ability to pay and network bandwidth access to the Internet. This development is called cloud computing. [0003] Server virtualization technology allows a pool of servers to be managed as essentially one large computer resource. ...

AI Technical Summary

Problems solved by technology

However, such multicast protocol support is not supported by cloud systems because these multicast protocols need to maintain a large amount of control state beyond the capacity of the host and will degrade the performance of the data center and all cloud services
