Tunnelling

This is yet another process that enables companies to become ImvS ready without much effort. According to a white paper from Brocade Communications, “Tunnelling allows an ‘envelope’ using one address type to be put inside another that uses a different address type. For example, an envelope using ImvS addresses can be put inside an envelope that uses Imv4. This envelope can then be routed over an existing Imv4 network. At the destination router, the outside Imv4 envelope is discarded, and the ImvS envelope is used to forward the electronic information to an ImvS device. This can also work the other way, by putting Imv4 envelopes inside ImvS envelopes. Although tunnelling can be used to move incompatible envelopes across dissimilar networks, this approach complicates network design and management,
