摘要： A method of reconfiguring a network having a transport plane for carrying subscriber traffic flows within end-to-end connections, a control plane for managing at least a portion of resources of the transport plane allocated to each connection, and a management plane for implementing management functions in the control plane and any resources of the transport plane that are not managed by the control plane. The method comprises installing an updated version of a control plane name space for a target node of the network. For each connection traversing the target node: a control plane to management plane migration is performed for removing connection state in the control plane associated with the connection, so as to transfer ownership of the connection from the control plane to the management plane; followed by a management plane to control plane migration for installing new connection state in the control plane associated with the connection, so as to transfer ownership of the connection from the management plant to the control plane, the new connection state being defined using the updated version of the control plane name space.

摘要： The invention is directed to optimizing setup of a VCAT connections using (largest) CCAT containers so as to minimize the number of cross-connection commands needed to enable data transfer. A system and method are provided for enhancing VCAT networks to include faster service restoration rates and faster connection setup times. One embodiment includes expanding available VCAT timeslots to include available CCAT timeslots. A routing and signaling control module alerts a source network element, internal network elements and a destination network element that the data transmission includes VCAT payloads rather than the expected CCAT payloads. By issuing this alert, the routing and signaling control module instructs an end-point monitoring function to overlook any mismatch between the expected CCAT rate and the received VCAT traffic. Otherwise, if the mismatch is not overlooked, then the end-point monitoring function will squelch the received VCAT traffic, which terminates the data communication

摘要： Virtual routers that abstract photonic sub-domains are provided for GMPLS networks. A virtual router uses a link viability matrix to keep track of the set of viable connections between inputs and outputs of a photonic sub-domain. A virtual router may receive RSVP-TE signaling messages and either allocate a working input to output link pair or, if explicitly signaled, verify that the requested link is currently viable. A virtual router also advertises, in its link state updates, the current set of possible outputs for any input link. Shortest path computations can be implemented utilizing virtual routers by modifying a topology graph in accordance with the link viability matrix of the virtual router.

摘要： Methods of computing a path through a network between a source node and a destination node. At the source node, an explore message is launched into at least one link hosted by the source node. The explore message includes a path vector containing a node identifier of the source node. At a node intermediate the source node and the destination node, the explore message is received, and each link hosted by the node that can be operably added to the path is identified. A respective node identifier of the node is added to the path vector of the explore message, which is then forwarded through each identified link. At the destination node, the respective path vector is extracted from at least one received explore message.

摘要： The present disclosure provides systems and methods for administrative boundaries in a single domain optical network such as emulation of an External network-network interface (ENNI) using an Internal-Network to Network Interface (INNI). For example, in a single monolithic domain, a network and associated network elements may discover network elements, build topology, compute paths, establish new calls, etc. A user may identify/mark specific links as emulated “ENNI” links with the specific links actually being INNI links. As a call traverses this emulated link, a new call is initiated (much in the same way a new call segment would be created for a call). Signaling proceeds as normal. When the call set-up is fully complete, instead of a single call segment, many call segments exists. Advantageously, this allows use of INNI control plane features while allowing a network operator to future-proof their network by installing call segments at future boundary points.

摘要： A method and system for changing the extent of data plane resources controlled by a control plane for a network connection which spans a contiguous set of nodes controlled by existing network control resources is disclosed. This is done in a non-disruptive manner. This typically involves two steps: i) Creating a new set of control plane resources for said network connection such that said data plane resources are shared with said existing network control resources; and ii) then terminating the existing network control resources such that said data plane resources are fully transferred to the new set of control plane resources without disrupting said network connection. The existing network control resources can be either a control plane resource or a non control plane resource. An example of a non control plane resource is network management software (e.g., an OSS (Operation Support System)), which forms part of the Management Plane. It should be noted that this does not need to be done for a complete end-to-end connection, but rather can be executed for the portion of the end-to-end connection which is to be controlled by the control plane.
摘要翻译：公开了一种用于改变跨越由现有网络控制资源控制的连续的节点集合的网络连接的控制平面控制的数据平面资源的范围的方法和系统。这是以非破坏性的方式完成的。这通常包括两个步骤：i）为所述网络连接创建一组新的控制平面资源，使得所述数据平面资源与所述现有网络控制资源共享; 以及ii）然后终止现有的网络控制资源，使得所述数据平面资源被完全传送到新的控制平面资源集合而不会中断所述网络连接。现有的网络控制资源可以是控制平面资源或非控制平面资源。非控制平面资源的一个例子是形成管理平面的一部分的网络管理软件（例如，OSS（操作支持系统））。应当注意，对于完整的端到端连接不需要这样做，而是可以对要由控制平面控制的端对端连接的部分执行。
