Managing communications for modified computer networks

摘要

Techniques are described for managing communications between multiple computing nodes, such as computing nodes that are part of a virtual computer network. In some situations, various types of modifications may be made to one or more computing nodes of an existing virtual computer network, and the described techniques include managing ongoing communications for those computing nodes so as to accommodate the modifications. Such modifications may include, for example, migrating or otherwise moving a particular computing node that is part of a virtual network to a new physical network location, or modifying other aspects of how the computing node participates in the virtual network (e.g., changing one or more virtual network addresses used by the computing node). In some situations, the computing nodes may include virtual machine nodes hosted on one or more physical computing machines or systems, such as by or on behalf of one or more users.

主权项

1. A computer-implemented method comprising:
managing, by one or more configured computing systems, a first communication that specifies a first virtual network address associated with a first computing node of a first virtual computer network, the managing of the first communication being based at least in part on mapping information for the first virtual computer network that associates the first virtual network address with a distinct substrate network address for the first computing node; after the managing of the first communication, determining, by the one or more configured computing systems, to initiate a change to the first computing node that results in a modification of the associated first virtual network address for the first computing node or of the substrate network address for the first computing node; and managing, by the one or more configured computing systems and based at least in part on updated mapping information for the first virtual computer network, a second communication sent to the first computing node, the updated mapping information for the first virtual computer network reflecting the change to the first computing node.
