20140269716 | EXTENDED TAG NETWORKING - 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. | 09-18-2014 |
20140280834 | PROGRAMMABLE MANAGEMENT ENGINE FOR NETWORKS - 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. | 09-18-2014 |
20140280898 | ALLOCATING COMPUTING RESOURCES BASED UPON GEOGRAPHIC MOVEMENT - 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. | 09-18-2014 |
20140365634 | Programmable Network Analytics Processing via an Inspect/Apply-Action Applied to Physical and Virtual Entities - Techniques are provided to programming network analytics processing in virtual and physical network devices, useful for software-defined networking (SDN). A controller, e.g., a so-called SDN controller, is configured to identify a control-plane or data-plane flow originating, terminating or transiting a physical or virtual network element. The controller generates one or more network analytics processing actions to be performed by the physical or virtual network element based on inspection of traffic by the physical or virtual network element. The controller forms or generates an inspect/apply-action message containing information identifying the control-plane or data-plane flow for inspection and the one or more network analytics processing actions to be performed. The inspect/apply-action message is sent to the physical or virtual network element. | 12-11-2014 |

20120144066 | DYNAMICALLY GENERATING APPLICATION-LAYER TRAFFIC OPTIMIZATION PROTOCOL MAPS - In general, techniques are described for using routing information obtained by operation of network routing protocols to dynamically generate network and cost maps for an application-layer traffic optimization (ALTO) service. For example, an ALTO server of an autonomous system (AS) receives routing information from routers of the AS by listening for routing protocol updates outputted by the routers and uses the received topology information to dynamically generate a network map of PIDs that reflects a current topology of the AS and/or of the broader network that includes the AS. Additionally, the ALTO server dynamically calculates inter-PID costs using received routing information that reflects current link metrics. The ALTO server then assembles the inter-PID costs into a cost map that the ALTO server may provide, along with the network map, to clients of the ALTO service. | 06-07-2012 |
20120224506 | ADVERTISING TRAFFIC ENGINEERING INFORMATION WITH THE BORDER GATEWAY PROTOCOL - In general, techniques are described for distributing traffic engineering (TE) link information across network routing protocol domain boundaries using a routing protocol.

A path computation module of the network device computes a traffic engineered path by selecting the traffic engineering link for inclusion in the traffic engineered path based on the traffic engineering information. | 09-06-2012 |
