摘要： Bandwidth usage for an existing communication tunnel between a first device and second device is monitored. A determination is made that additional bandwidth is required for communication between the first network device and the second network device. A determination is made that for the addition of the additional bandwidth would exceed available bandwidth for the existing tunnel. Additional bandwidth is established between the first network device and the second network device.

摘要： Embodiments described herein use APIs on network devices in a SDN enabled network to monitor the network traffic flowing through the network devices and determine an identity of the client initiating the network traffic. Specifically, the APIs provide a user application with user credentials, IP addresses, MAC addresses, and other identifying information mined from the network flows. Once the identity is found, the application may identify the client's current geographic location. The network devices may continue to monitor the network devices to identify any movement events associated with the client. In response to a movement event, the application may reallocate resources proximate to the new geographic location of the client.
摘要翻译：本文描述的实施例使用在启用SDN的网络中的网络设备上的API来监视流经网络设备的网络流量并确定启动网络流量的客户端的身份。具体来说，API为用户应用提供从网络流中挖掘的用户凭证，IP地址，MAC地址以及其他识别信息。一旦找到该身份，应用程序可能会识别客户当前的地理位置。网络设备可以继续监视网络设备以识别与客户端相关联的任何移动事件。响应于移动事件，应用可以重新分配靠近客户端的新地理位置的资源。

摘要： Techniques are disclosed to extend routing rules from external services. A request is received to modify a specified rule in a network element of a network. The specified rule governs disposition of a network flow specific to an application. The request is received via a communications channel configured to expose an application programming interface (API) to the application. The request is interpreted at a network abstraction layer of the network element. The request is converted into a command at a service implementation layer of the network element. The command is executed to modify the specified rule in the network element, responsive to the request.

摘要： A network node may contain a virtual software-defined networking (SDN) switch and a local a management engine (e.g., a software application) for generating performance metrics based on received management plane traffic. Specifically, the virtual SDN switch may identify and forward received management plane traffic to the local management engine. In turn, the management engine evaluates the management plane traffic to generate performance metrics without forwarding the management plane packets to the remote SDN controller. The management engine may compare the metrics to one or more thresholds to determine the current state or health of the data paths in a network. If a threshold is exceeded, the management engine may transmit an alert to the virtual SDN switch to perform a corrective action - e.g., using a backup data path after the primary data path fails.
摘要翻译：网络节点可以包含虚拟软件定义网络（SDN）交换机和本地管理引擎（例如，软件应用程序），用于基于所接收的管理平面流量来生成性能度量。具体地说，虚拟SDN交换机可以识别并转发接收到的管理平面流量到本地管理引擎。反过来，管理引擎评估管理平面流量，以生成性能指标，而不将管理平面数据包转发到远程SDN控制器。管理引擎可以将度量与一个或多个阈值进行比较，以确定网络中数据路径的当前状态或运行状况。如果超过阈值，则管理引擎可以向虚拟SDN交换机发送警报以执行校正动作 - 例如在主数据路径发生故障之后使用备份数据路径。

摘要： A session border controller includes a first port to communicate with a user using a first signaling protocol, a second port to communicate with a content provider using a second signaling protocol, and a processor coupled to the first and second ports. The session border controller may send a PLAY message to the content provider to begin delivery of a content destined for the user. The session border controller may further receive a first media stream including the content and content provider information from the content provider. The session border controller may further create a second media stream that includes the content without the content provider information, and deliver the second media stream to the user.

摘要： Techniques are provided for enabling tag networking. In one example, a network device (e.g., switch, router, etc.) is configured to receive a packet of a traffic flow and to analyze the traffic flow to determine the packet belongs to a particular type of traffic. The network device can then add and/or change a tag in a data field of the packet. The tag, among other things, serves as an identifier for the particular type of traffic flow. The tag is identifiable by a downstream node that is preconfigured to recognize the tag and to carry out logic in response to recognizing the tag. Advantageously, the tag functionality of the present approach provides a generalized way of adding information to packets; the information and the associated functionalities are customizable during a runtime of the network.

摘要： In one embodiment, a particular device in a computer network maintains a locally owned tunnel-state table, and joins a distributed hash table (DHT) ring. In addition, the locally owned tunnel-state table is shared with other devices of the DHT ring to establish a DHT-owned tunnel-state table. The particular device (and other devices) determines ownership of link-state advertisements (LSAs) for a specific portion of a traffic engineering database (TED) according to the DHT ring. As such, when the particular device (or any device) computes a path for a tunnel using a local TED, the particular device may request permission to use resources along the computed path that were advertised in particular LSAs from owners of those particular LSAs when not owned by the particular device.
摘要翻译：在一个实施例中，计算机网络中的特定设备维护本地拥有的隧道状态表，并且连接分布式哈希表（DHT）环。此外，本地拥有的隧道状态表与DHT环的其他设备共享，以建立DHT拥有的隧道状态表。特定设备（和其他设备）根据DHT环确定针对流量工程数据库（TED）的特定部分的链路状态通告（LSA）的所有权。因此，当特定设备（或任何设备）使用本地TED计算隧道的路径时，特定设备可以请求许可沿着计算出的路径使用资源，这些资源在特定LSA的特定LSA中被从这些特定LSA的所有者通告由特定设备拥有。

摘要： A node in an overlay network requests a ranked list of other nodes in multiple areas of the overlay network that can provide a desired piece of content or service to the requesting node. A separate node such as a router generates the ranked list using a routing algorithm, returning the list to the requesting node so that the requesting node may acquire the desired content or service from the nearest node in the overlay network.

摘要： In system of networks that are not fully meshed with each other and that are capable of processing distributed hash table (DHT) Put and Get messages, message flooding of GET messages is limited by maintaining a list of DHTs the GET has visited. Also, PUT messages include not only the storage location key in the home network but also a list of networks that the PUT has visited, in essence establishing a dynamically changing path within the PUT back to the home network.
摘要翻译：在没有完全互相关联并且能够处理分布式散列表（DHT）Put和Get消息的网络系统中，GET消息的消息泛滥受到GET访问的DHT列表的限制。此外，PUT消息不仅包括家庭网络中的存储位置密钥，而且还包括PUT访问的网络列表，其本质上在PUT内建立动态改变的路径回到家庭网络。
