摘要： A method of path protection for a connection-oriented packet switched communications network is described using a protection hub in communication with a worker hub via a core protection path. Both the worker hub and the protection hub communicate with at least one provider edge device via a respective worker and protection paths. The method detects a failure in the communications network, indicates the failure to the at least one of the provider edge device, the worker hub, and the protection hub. The method then employs the core protection path if a failure occurs along a worker path is detected, or a worker path and a protection path in parallel if a failure occurs along the core protection path.

摘要： A Common Public Radio Interface (CPRI) link involves using a protocol stack having a CPRI layer and an emulation layer to emulate a point to point link, to enable the CPRI link to operate over a packet switched network. The emulation layer can be a pseudowire emulation which encapsulates multiple CPRI frames in a packet with overhead. A multiplexing layer such as Internet Protocol (IP) or Multiprotocol Label Switching (MPLS) can be used, for sending the packet over an Ethernet network. The usual need for a point to point infrastructure for the CPRI link can be avoided and the CPRI link can be implemented over more complex but usually cheaper packet networks, thus reducing costs or enabling more widespread application over existing packet networks. This applies whether the packet network is dedicated to the CPRI link, or shared with other packets. It can be useful for distributed radio base stations.
摘要翻译：通用公共无线电接口（CPRI）链路涉及使用具有CPRI层和仿真层的协议栈来模拟点对点链路，以使得CPRI链路能够通过分组交换网络进行操作。仿真层可以是在具有开销的分组中封装多个CPRI帧的伪线仿真。可以使用诸如因特网协议（IP）或多协议标签交换（MPLS）的复用层，用于通过以太网发送分组。可以避免对CPRI链路的点对点基础设施的通常需要，并且可以通过更复杂但通常更便宜的分组网络来实现CPRI链路，从而降低成本或使现有分组网络上的应用更广泛。这适用于分组网络是专用于CPRI链路还是与其他分组共享。这对于分布式无线电基站是有用的。

摘要： An optical network is configured to provide an optical reroute over a backup path (2139) during a failure in a signal path (2133). The network comprises a first node (B). A second node (C) is coupled to receive a signal from the first node (B) via the signal path (2133), and a backup signal via the backup path (2139). The network is adapted to transmit a signal and a corresponding backup signal from the first node to the second node even when there is no failure in the signal path (2133), wherein the backup signal is blocked at the second node (C) when there is no failure in the signal path (2133). Embodiments of the invention utilize the broadcast and blocking functionalities of a wavelength selective switch (WSS) device. Such WSS devices enable, in the case of a failure of a link, the fast switchover of optical traffic onto local detours within a reduced time.

摘要： A method of operating a control plane having a centralised network management system (10), control domain servers (20) and a plurality of forwarding elements (30), for controlling respective network entities (L2), and grouped into control domains (21, 22, 23). Each domain has a control domain server. Automatic checking for inconsistencies (110, 115, 210, 310, 320, 450) between the records held at the different parts of the control plane, involves comparing checklists of the records of the circuits stored at the different parts of the control plane. If an inconsistency is found, there is automatic updating (120, 220, 230, 460) of the records using a copy sent from another of the parts of the control plane. The checklists can avoid the need to forwarding entire copies.

摘要： Setting up a label switched path (LSP) for traffic between nodes of a network, involves sending a request message requesting reservation of resources for the requested LSP, from an ingress node (10) via intermediate nodes (40) and returning an acknowledgement message to an upstream node along the path. Absence of an acknowledgement from the downstream node, that the request message was received, is detected. Whether the given node should react to the detected absence can be determined from an indication (R) in the request message. Thus other nodes can react more quickly to take remedial action, to reroute or to remove the resource reservations without a long wait for a time out or a refresh message from the waiting ingress node, to enable more efficient use of the resources.

摘要： A data communications system has a plurality of nodes connected by a plurality of links. A subset of the links and nodes forms a worker path for carrying worker data through the communications system, and a further subset of links and nodes provides a protection path for carrying other data in the absence of a fault in the worker path and for providing an alternative path for the worker data in the event of a fault in the worker path. The alternative path is predetermined prior to the detection of a fault in the worker path.
