Filed:

Jan 5, 2011

Appl. No.:

12/985091

Inventors:

JEFFREY A. SANDEN - Camp Hill PA, US

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION - Armonk NY

International Classification:

G06F 15/173
G06F 9/455

US Classification:

709238, 718 1

Abstract:

A system and associated method for optimizing routing of data traffic for a host virtual machine. The host virtual machine communicates with an Internet Protocol (IP) network via a default gateway of a source site prior to migration. A migration service process migrates the host virtual machine from the source site to a target site, which is geographically remote from the source site and consequently changes routing efficiency of the data traffic between the host virtual machine and the IP network. The migration service process reconfigures routing parameters of the migrated host virtual machine for data traffic going out to the IP network from the host virtual machine. The migration service process examines the IP network configurability and subsequently reconfigures the IP network for inbound data traffic coming into the migrated host virtual machine from the IP network when available.

Abstract:

An approach is provided for establishing a private network connection between source and target cloud data centers (CDCs). Requirements of the private network connection are received. Network service providers (NSPs) providing a network service to the source and target CDCs are determined. Performance information of respective NSPs is determined. Performance information of NSP(s) are determined to satisfy the requirements. One of the NSP(s) is selected based on the corresponding performance information optimally satisfying the requirements. First and second connection endpoints of the private network connection are generated in the source and target CDCs, respectively. Based on the first and second connection endpoints and responsive to a request from the target CDC to the selected NSP to attach the target CDC to the private network connection, the private network connection is established.
