摘要： A transmission system comprises nodes coupled in a ring via two multiplexed transmission paths having opposite transmission directions. The two paths can be time, space, or wavelength division multiplexed. Bidirectional communications between any two nodes are provided in normal operation using both paths around a first, most direct, part of the ring. In the event of a fault affecting such communications, a protection switch is made to maintain bidirectional communications between the two nodes using both paths around a second, remaining, part of the ring. In this manner, each path can simultaneously carry both normal and protection switched signals. In an embodiment of the invention, only the two nodes adjacent a fault need be aware of the fault, each of these nodes effecting a protection switch for signals terminated at the node and effecting a protective loopback for other signals needing protection. The invention enhances the total capacity of the paths for carrying normal and protection switched signals. A network may comprise a plurality of such ring transmission systems intersecting at at least one network node, the network node comprising a node of each ring and a cross connect switch for switching signals therebetween.
摘要翻译：传输系统包括通过具有相反传输方向的两个复用传输路径耦合在环中的节点。这两条路径可以是时间，空间或波分复用。在正常操作中，使用围绕环的第一，最直接的部分的两个路径来提供任何两个节点之间的双向通信。在影响这种通信的故障的情况下，使用围绕第二剩余部分环路的两个路径来保护两个节点之间的双向通信的保护开关。以这种方式，每个路径可同时携带正常和保护切换信号。在本发明的一个实施例中，只有与故障相邻的两个节点需要知道故障，这些节点中的每个节点对终止在节点处的信号执行保护开关，并对需要保护的其他信号进行保护环回。本发明增强了用于承载正常和保护开关信号的路径的总容量。网络可以包括与至少一个网络节点相交的多个这样的环形传输系统，网络节点包括每个环的节点和用于在它们之间切换信号的交叉连接开关。

摘要： Embodiments are directed to establishing the integrity of a portion of data on at least one level of a plurality of network stack levels and automatically continuing an established federation relationship between at least two federation computer systems. In an embodiment, a first federation computer system receives a digital signature corresponding to a computer system signed by a digital signature which includes the computer system's identity and other federation relationship information configured to establish a trusted federation relationship between a first federation computer system and a second federation computer system. The first federation computer system attempts to validate the received digital signature at a first level of a network stack and determines that the validation at the first network stack layer was unsuccessful. The first federation computer system then validates the received digital signature at a second, different level of the network stack.

摘要： The authentication of identities within a realm in which some identities are authenticated using direct authentication, and some identities are authenticated using federated authentication. Requests for service from valid identities in the realm that are to be authenticated by direct authentication are responded to with a direct authentication interface. Requests for service from valid identities in the realm that are to be authenticated by federated authentication are responded to with a federated authentication interface. Requests for service from invalid identities are responded to pseudo-randomly with either the direct authentication interface or the federated authentication interface.

摘要： A communications system is provided having SONET communications channels extending between first and second locations. The channels include pairs of forward and reverse channels for carrying traffic in normal operation between first and second locations and a protection channel for carrying traffic of one channel in the event of a fault. Each pair of forward and reverse channels is provided on a shelf at each location, the shelves having the same relative position at both locations and the protection channel is provided on a protection shelf. The protection channel includes, between the first and second locations, a forward optical link and a reverse optical link and at each of the first and second locations, a single protection loop, coupling the forward and reverse optical links, that forms the protection channel. The protection loop is used to provide, at each location, a local virtual protection loop for indicating the protection requirements and status of the respective location, and a remote virtual protection loop for indicating the protection requirements and status of the location remote from the respective location. The local protection loop is provided by inserting K1 and K2 bytes into E1 slots of STS-1 #25 and #2, respectively. The remote protection loop is provided by inserting K1 and K2 bytes into E1 slots of STS-1 #26 and #3, respectively.

摘要： Verification that a customer has ownership over a particular domain name. A computing system receives a request to provide a network service to a customer for action upon a particular domain name. In response, the computing system provides information to the customer over a network, and instructs the customer to edit a domain name record for the particular domain name using the provided information. For instance, the customer might be provided with a Globally-Unique IDentifier (GUID), and instruct the customer to insert the GUID into a particular record associated with the domain name in the DNS system. Upon verifying that the domain name record has indeed been edited using the provided information, the customer is confirmed as being an owner of the domain name.

摘要： A binary data signal is regenerated with respect to three threshold levels, one of which is derived from and lies between the other two so that it is an optimum level for producing a regenerated output signal. Two control loops are used to produce the other two threshold levels to produce regenerated signals with predetermined error rates, the errors occurring on the two control loops for the two respective states of the binary data signal, whereby the optimum threshold level is maintained regardless of the nature of signal degradation. The arrangement provides rapid performance monitoring which can also be used to adjust other parameters, such as detector bias, equalizer tuning, and clock phase, for optimum performance in an active and ongoing manner.
