Abstract: A system and a method for interpreting normal and errored segments of network measurement data differently, and processing network measurement data, including: receiving a first query for network measurement data; extracting compressed network measurement data and error metadata from a repository database based upon the first query; decompressing the extracted compressed network measurement data; retrieving an error segment of raw network measurement data based upon the error metadata; and merging the error segment of raw network measurement data with the decompressed extracted compressed network measurement data to produce extracted network measurement data.

Abstract: A method for routing traffic between a source node and a destination node in a network comprises: identifying a first group level at which a source group vector and a destination group vector differ; obtaining one or more first route segments between a first source group and a first destination group at the first group level; computing an end-to-end route between the source node and the destination node based on at least the one or more first route segments; and routing traffic between the source node and the destination node on the end-to-end route.

Abstract: Systems, methods, apparatuses, and computer program products for packet latency reduction in mobile radio access networks. One method may include, when a buffer of a first sublayer of a wireless access link is empty and there is a new data unit in the first sublayer or when the first sublayer buffer is not empty and a data unit leaves a second sublayer buffer, comparing the number of data units currently stored in the second sublayer buffer with a queue length threshold that defines a total amount of space in the second sublayer buffer. When the number of data units currently stored in the second sublayer buffer is less than the queue length threshold, the method may also include transferring the data unit from the first sublayer to the second sublayer.

Abstract: Various embodiments relate to a path computation element (PCE) configured to control a network having ingress edge nodes, interior nodes, and egress edge nodes, including: a network interface configured to communicate with the network; a memory; and a processor coupled to the memory and the network interface, wherein the processor is further configured to: receive a request for a first continuous guaranteed latency (CGL) flow to be carried by the network; make routing and admission control decisions for the requested first CGL flow without provisioning of the first CGL flow and the configuration of schedulers in the interior nodes of the network; and provide flow shaping parameters to a flow shaper at an ingress edge node of the first CGL flow.

Abstract: Aspects described herein relate to various methods, systems and apparatuses that can be used to define a network slice based on descriptions of the computing functions involved in a network service, and to configure the network slice using resources that are associated with the descriptions. For example, a network slice may be defined based on whether the network service requires tunneling or data encryption. The network slice may be configured using resources that perform those tunneling and data encryption functions.

Abstract: An application specific interface (AA-NAPI) associated with an application for the purpose of controlling the networking aspects of the application session is provided by communication service provider (CSP). Cost model of network service types associated with a specific application type is learned by using the AA-NAPI. For each service-point joining the session, network properties are queried by using the AA-NAPI. During continuous service quality monitoring, upon detection of quality degradation leading to the decision to upgrade session quality, network service-type associated with a specific server-point is changed by using the AA-NAPI. Network specific actions are taken to reconfigure the network so that the requested service type is received by the specific service-point. New network capability is activated to improve network service level by using the AA-NAPI. Network specific actions are taken by the network to install new network capabilities so that the specific service-point's service quality is improved as requested.

Abstract: A first optical node is configured for deployment in an optical network including second optical nodes having a ring topology. The first optical node includes an optical encoder and a decoder. The optical encoder is configured to form a third optical signal for transmission into the optical network by combining a first optical signal generated by the first optical node with a second optical signal received by the first optical node from the second optical nodes. The decoder is configured to extract information from fourth optical signals received from the second optical nodes. In some cases, the first optical node includes a receive buffer configured to store information representative of the fourth optical signals received from the second optical nodes and a transmit buffer configured to store information used to generate the first optical signal.
