摘要： The present disclosure relates a network, a network element, a system, and a method providing an efficient allocation of protection capacity for network connections and/or services. These may be for services within a given Virtual Private Network (VPN) or Virtual Machine (VM) instance flow. Network ingress/egress ports are designed to be VM instance aware while transit ports may or may not be depending on network element capability or configuration. A centralized policy management and a distributed control plane are used to discover and allocate resources to and among the VPNs or VM instances. Algorithms for efficient allocation and release of protection capacity may be coordinated between the centralized policy management and the distributed control plane. Additional coupling of attributes such as latency may provide more sophisticated path selection algorithms including efficient sharing of protection capacity.

摘要： A method for mitigating network attacks includes receiving traffic status information from sentries distributed in a network, and analyzing the traffic status information to detect an attack on the network. In response to the attack, an isolated network slice is created. For the isolated network slice, a deceptive network resource is created in isolated network slice. The method further includes transmitting instructions to route malicious traffic to the deceptive network resource.

摘要： The present invention provides a directionless optical architecture for reconfigurable optical add/drop multiplexers (ROADMs) and wavelength selective switches (WSSs). The directionless architecture utilizes a directionless wavelength switch coupled between client devices and ROADMs/WSSs to eliminate the need to hard-wire client devices to a wavelength division multiplexed (WDM) network. Accordingly, client device connections can be automatically routed without manual intervention to provide a highly resilient network design which can recover route diversity during failure scenarios. Additionally, the present invention minimizes deployments of costly optical transceivers while providing superior resiliency. Further, the present invention couples the directionless optical architecture and associated optical protection mechanisms with existing mesh restoration schemes to provide additional resiliency.
摘要翻译：本发明提供了一种用于可重新配置的光分插复用器（ROADM）和波长选择开关（WSS）的无向光学架构。无方向结构使用耦合在客户端设备和ROADM / WSS之间的无方向波长切换，以消除将硬线客户端设备连接到波分复用（WDM）网络的需要。因此，可以自动路由客户端设备连接，而无需手动干预，以提供高度弹性的网络设计，可在故障情况下恢复路由分集。另外，本发明使昂贵的光收发器的部署最小化，同时提供优异的弹性。此外，本发明将无方向光学架构和相关联的光学保护机制与现有的网格恢复方案相结合，以提供额外的弹性。

摘要： The present disclosure provides hybrid packet-optical private network systems and methods for a private and dedicated multi-point Ethernet Private Local Area Network (EPLAN). The network systems and methods include a Layer 1 infrastructure service with the inclusion of reserved, dedicated packet switch capacity upon which clients can build their personal, private packet networks. In the systems and methods described herein, packet networking methods are not used to partition the isolated LAN connectivity. Instead, dedicated Ethernet Private LANs (EPLs) are defined between dedicated virtual switching instances (VSIs) that are defined, as necessary, within larger packet-optical switches. Each VSI is partitioned from the remainder of its packet switch fabric as a dedicated, private resource for a specific EPLAN. A packet network is then built by the customer on top of the private EPLAN bandwidth and operated as an isolated, private network with no influence by other carrier's network resources.

摘要： The present disclosure provides distributed domain network planning systems and methods. The network planning systems and methods include a distributed domain network planning system that adapts planning concepts to networks operated by modern distributed control planes, such as ASON/ASTN, GMPLS, etc. The network planning systems and methods operate on a multi-domain network utilizing a control plane and local planning systems associated with each individual domain in the multi-domain network. The network planning systems and methods also operate on a single domain network utilizing a control plane and local planning systems associated with the single domain network. The network planning systems and methods build on a distributed control plane philosophy that the network is the database of record. There is significant operational value to distributing the planning function of a large network using the systems and methods disclosed herein.
