Abstract: There is provided a method for handling a service request. The method is performed by a first service communication proxy (SCP) node. In response to receiving a first request from a first Network Function (NF) node for a further NF node to provide a first service, the first SCP node selects (102) a second NF node to provide the first service and stores (104) an identifier of the second NF node. The first SCP node also initiates transmission (106) towards the second NF node of the first request. In response to receiving, from the second NF node, a first response, the first SCP node stores (108) location information of the second NF node. The location information of the second NF node is stored in association with the identifier of the second NF node. The first SCP node also initiates transmission (110) of the first response towards the first NF node.

Abstract: In various embodiments, a media delivery application transmits encoded chunks of a media title to a playback application. In operation, the media delivery application receives, via a media channel, an encoded chunk request that has been transmitted over a TCP connection. The media delivery application also receives, via a side channel, a pacing specification that is associated with the encoded chunk request and has been transmitted over the TCP connection. As per the encoded chunk request, the media delivery application retrieves encoded chunk content. The media delivery application sets a parameter associated with the TCP connection equal to a parameter value based on the pacing specification. Subsequently, the media delivery application causes TCP segments corresponding to the encoded chunk content to be transmitted, via the media channel, over the TCP connection in accordance with the first parameter value.

Abstract: To perform pattern-based detection of malicious URLs, patterns are first generated from known URLs to build a pattern repository. A URL is first normalized and parsed, and keywords are extracted and stored in an additional repository of keywords. Tokens are then determined from the parsed URL and tags are associated with the parsed substrings. Substring text may also be replaced with general identifying information. Patterns generated from known malicious and benign URLs satisfying certain criteria are published to a pattern repository of which can be accessed during subsequent detection operations. During detection, upon identifying a request which indicates an unknown URL, the URL is parsed and tokenized to generate a pattern. The repository of malicious URL patterns is queried to determine if a matching malicious URL pattern can be identified. If a matching malicious URL pattern is identified, the URL is detected as malicious.

A higher-tier system may include an enterprise or organization wide network or service that includes at least a part of the lower-tier system. Once the higher-tier system monitoring component is installed, the higher-tier and lower-tier system monitoring components use an interface to operate with one another to form a single larger instance of an organization wide monitoring system. The combination of the higher-tier system monitoring component and the one or more lower-tier system operating components performs monitoring aspects of the overall information technology environment based at least in part on machine data produced and made searchable to provide monitoring results.

Abstract: Systems and methods for providing an integrated or Smart NIC-based hardware accelerator for a network security device to facilitate identification and mitigation of DoS attacks is provided. According to one embodiment, a processor of a network security device receives an application layer protocol request from a client, directed to a domain hosted by various servers and protected by the network security device. The application layer protocol request is parsed to extract a domain name and a path string. The hardware acceleration sub-system updates rate-based counters based on the application layer protocol request by performing a longest prefix match on the domain name and the path string. When a rate threshold associated with the rate-based counters is exceeded, a challenge message is created and transmitted to the client, having embedded therein the application layer protocol request; otherwise the application layer protocol request is allowed to pass through the network security device.
