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： 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 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 protection scheme for a metro optical network involves programming ingress nodes and egress nodes with a primary multicast label switched path (LSP) and a back-up LSP to provide one-to-one protection. The primary and back-up LSPs are configured prior to the occurrence of a network fault to allow the network to transmit multicast communication when the fault occurs. Particularly, multicast communications are sent on the primary LSP during normal operation. However, when a network fault occurs, the nodes also send a duplicate multicast communication over the back-up LSP. Configuring the primary and back-up LSPs prior to the fault occurring avoids the need for signalling to establish a working LSP after a fault occurs.
摘要翻译：用于城域光网络的保护方案涉及使用主要组播标签交换路径（LSP）和备用LSP对入口节点和出口节点进行编程，以提供一对一保护。在发生网络故障之前配置主备份LSP和备份LSP，以允许网络在故障发生时传输组播通信。特别地，在正常操作期间，在主LSP上发送组播通信。但是，当发生网络故障时，节点也通过备份LSP发送重复的组播通信。在发生故障之前配置主备份和备份LSP避免了在发生故障后建立LSP的信令。
