摘要:
Communication between a network device in a first network and a network device in a second network is provided, where the first network operates in accordance with a first communication protocol and the second network operates in accordance with a second communication protocol. An alias is assigned to a target network device in the first network, the alias being compatible with the communication protocol of the second network The assigned alias is translated to an address for a target network device, the translated address being compatible with the communication protocol of the first network. Apparatus, for assigning the alias and for translating it are separately addressable in one or both of the networks, and the assigned alias corresponds to an address of the translating apparatus, such that, when a network device in the second network sends one or more communication(s) using an address including the assigned alias, each communication is routed to the translator, whereupon the translator translates the alias into the address of the target network device in the first network and sends the communication(s) into the first network.
摘要:
An interface for use between two IPv6 domains separated by an IPv4 domain includes a protocol converter, an encapsulator/un-encapsulator and a controller.
摘要:
A tunnel is established across an IPv4 domain for the transport of packets from a source host on one IPv6 domain to a destination host on another IPv6 domain, there being respective interfaces between the IPv4 domain and the IPv6 domains.
摘要:
A wavelength is selected for use in transmitting optical data along a path in an optical network. Wavelengths that are available for use end-to-end along the path are found, the wavelengths that are available on each link attached to each node on the path are found and a wavelength that is available end-to-end and that is more available on the links attached to the nodes is selected.
摘要:
A path is established through an optical communications network. One or more partial paths are evaluated according to a first criterion, and candidate end-to-end paths are then evaluated according to a second criterion. The end-to-end path evaluation disregards candidate end-to-end paths that include partial paths not meeting the first criterion. A path is established by selecting one of the candidate end-to-end paths on the basis of the second criterion.
