Abstract: A system and method simulate a chat-based conversation with a human user. The system and method receive a text message through the chat system that enables a receiver to transmit an automatically generated response in real time during a chat session. The system and method recognize characters in a text message and generates an automatic prediction or classification using a conversational assistant pod that resides in a container. The system and method generate an automatic response and modify computing resources by replacing the conversational assistant pod and the container with a second conversational assistant pod and a second container without interrupting the chat session.

Abstract: The present disclosure provides a method for automatically predicting a topology of a network comprising a plurality of nodes. The method includes: selecting a path performance metric among a plurality of available metrics; obtaining path performance metrics of selected node pairs among the plurality of nodes; using the obtained path performance metrics to train a machine-learning model to predict the path performance metric for the remaining node pairs; and using the obtained and predicted path performance metrics to construct a topology of the network.

Abstract: In one embodiment, a resolution resiliency application performs robust domain name system (DNS) resolution. In operation, the resolution resiliency application determines that an authoritative name server that is responsible for a domain name specified in a DNS query is unavailable. In response to determining that the authoritative name server is unavailable, the resolution resiliency application performs operation(s) that modify one or more DNS records stored in a cache based on one or more resiliency policies associated with the authoritative name server. The resolution resiliency application then generates a DNS response to the DNS query based on a DNS record stored in the modified cache. Notably, unlike conventional techniques that may generate inaccurate DNS responses based on stale DNS records, the disclosed techniques increase the likelihood of providing clients with DNS responses that accurately provide requested information.

Abstract: In one embodiment, a resolution resiliency application modifies domain name service (DNS) resolution. In operation, the resolution resiliency application determines that an authoritative name server has begun recovering from a degraded state or receives a flush list update from the authoritative name server. In response, the resolution resiliency application performs operation(s) that modify a query rate and/or a cache. The query rate specifies a frequency associated with DNS queries transmitted to the first authoritative name server. The cache stores DNS record(s) received from the first authoritative name server. Finally, the resolution resiliency application generates a DNS response to a DNS query based on the modified query rate and/or the modified cache.

Abstract: In an example embodiment, zone information is received from a distributed database, the zone information including a mapping between each of a plurality of client applications and a corresponding zone. Then a first adapter is assigned to a first client application based on the mapping. A second adapter is then assigned to a second client application based on the mapping. When data is received from the first client application, the data from the first client application is parsed using the first adapter, producing output to a search core and an indexing core associated with a zone corresponding to the first client application.

Abstract: In one embodiment, a sender device in a network sends a plurality of uncompressed messages to a receiver device in the network. The sender device generates a sender-side compression dictionary based on the plurality of uncompressed messages. The receiver device also generates a receiver-side compression dictionary based on the uncompressed message. The sender device obtains an approval of the sender-side compression dictionary from the receiver device by sending a checksum of the sender-side compression dictionary to the receiver device, whereby the receiver device generates the approval by comparing the checksum of the sender-side compression dictionary to a checksum of the receiver-side compression dictionary. The sender device sends a compressed message to the receiver device that is compressed using the sender-side compression dictionary, after obtaining the approval of the sender-side compression dictionary from the receiver device.

Abstract: In an embodiment, a method monitors a plurality of data streams passing through a router in the connectivity service provider environment, and for each of the data streams, periodically samples packets at the router. The method further generates a stream signature based at least on the payload of the sampled packets. The method further includes, for each generated stream signature, attaching information to the stream signature. Such information may, for example, include time-stamp information for the stream signature, or an identification of the router. The method may further comprise storing the stream signatures corresponding to the data streams in a database. The stored stream signatures may be compared to determine matching stream signatures. Matching signatures may identify data streams that carry identical or similar content.

Abstract: Determining, in a geographically diverse storage system, a portion of a data chunk that comprises fewer non-relevant fragments of stored user data than the data chunk itself is disclosed, wherein communication of the portion, in lieu of the data chunk, can result in consumption of fewer network resources. Chunk table data that can indicate information about fragments comprising the chunk, such as memory locations of fragments, sizes of fragments, indexes of fragments, a relevancy flag, etc., can be determined and/or stored. In an operation of the geographically diverse storage system, such as generating a convolved chunk, deletion of a chunk, regeneration of a damaged chunk, etc., employing the portion of the data chunk can generally reduce consumption of network resources in comparison to communicating the entire data chunk itself inclusive of all non-relevant fragments.

Abstract: Embodiments of the present disclosure relate to a method for managing user information in a SIP network and a device thereof. The method comprises: initiating a restart timer after a SIP access gateway restarts; within an expiration period of the restart timer, sending a heartbeat reply message to the network element in response to a heartbeat message from a network element, the reply message including the time when the SIP access gateway restarts. If a difference between the time when the SIP access gateway restarts and a current time is less than a time interval between heartbeat messages, the network element sends a registration request to the SIP access gateway, where the registration request includes user information of all users represented by the network element. It is further disclosed a device implementing the method discussed above.

Abstract: The current document is directed to methods and systems that collect metric data within computing facilities, including large data centers and cloud-computing facilities. In a described implementation, lower and higher metric-data-value thresholds are used to partition collected metric data into outlying metric data and inlying metric data. The inlying metric data is quantized to compress the inlying metric data and adjacent data points having the same quantized metric-data values are eliminated, to further compress the inlying metric data. The resulting compressed data includes original metric-data representations for outlier data points and compressed metric-data representations for inlier data points, providing accurate restored metric-data values for significant data points when compressed metric data is decompressed.
