摘要： A method of communications employing a communications protocols defining respective responses to predetermined events, comprising: separating said protocol into a first group of behaviours defining responses to corresponding first, relatively frequently occuring, events, and a second group of behaviours defining responses to corresponding second, relatively infrequently occuring, events; Storing said first group at a first communications terminal, storing at least said second group at a store remote from said first terminal, and interconnected therewith via a communications channel; communicating from said first terminal using said first group of said protocols; on detecting an event other than one of said first events at said first terminal, signalling event-handling data from said store to said first terminal; and communicating from said first terminal using said event-handling data.

摘要： An address resolver system that assists a node in an IPv6 network to select an address for connectivity with a node in an IPv4 network when both DSTM and NAT-PT transition mechanisms are available. Native connectivity can be achieved by preferring an encapsulation or tunnelling mechanism such as DSTM where possible over a translation mechanism such as NAT-PT. A range of encapsulation and translation mechanisms are envisaged. The resolver determines capabilities of the node and of the application that requires the address in order to make the selection.

摘要： A method of establishing a path through an optical communications network is disclosed. Previously known method for establishing a path through an optical communications network include checking the viability of an end-to-end path once the complete end-to-end path has been selected. However, additional (and hence wasted) processing may be expended in selecting an end-to-end path that turns out not to be viable this increasing the network operating costs. In the proposed method one or more partial paths are evaluated according to a first criterion, candidate end-to-end paths are then evaluated according to a second criterion, wherein 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

摘要： The present invention concerns network address translation, and provides apparatus for providing communication between a network device in a first network and a network device in a second network, where the first network operates in accordance with a first communication protocol and the second network operates in accordance with a second communication protocol. The apparatus comprises (i) first means for assigning an alias to a target network device in the first network, the alias being compatible with the communication protocol of the second network ; (ii) second means for translating said assigned alias to an address for the target network device, said translated address being compatible with the communication protocol of the first network, wherein the first means and the second means are separately addressable in one or both of said networks, and said assigned alias corresponds to an address of the second means, such that, when a network device in the second network sends one or more communication(s) using an address comprising the assigned alias, the or each communication is routed to the second means, whereupon the second means translates the alias into the address of the target network device in the first network and sends the communication(s) into the first network.

摘要翻译：公开了一种通过光通信网络建立路径的方法。先前已知的用于通过光通信网络建立路径的方法包括一旦选择了完整的端到端路径，就检查端到端路径的可行性。然而，额外的（并因此浪费的）处理可能在选择端到端路径时花费太多，这增加了网络运营成本，结果不可行。在所提出的方法中，根据第一准则评估一个或多个部分路径，然后根据第二准则评估候选端到端路径，其中端到端路径评估不考虑候选端到端路径其中包括不符合第一条标准的部分路径。通过基于第二准则选择候选端到端路径之一来建立路径
