A mobile communication device for receiving an ad hoc temporary upgrade in quality of service (QoS). The mobile communication device comprises a processor, at least one cellular radio transceiver, a non-transitory memory, and an ad hoc service upgrade application. When executed by the processor, the application monitors wireless cellular communication on a network via the at least one cellular radio transceiver, detects a significant delay in the communication, generates a prompt on a GUI, the prompt comprising a plurality of options for an ad hoc temporary upgraded QoS, where each option is associated with a time period. The application further, based on a user input, requests a preferred roaming list (PRL) associated with the temporary upgraded QoS, receives the PRL, wherein the PRL is associated with providing the upgraded QoS on an allocated spectrum, activates the received PRL, and upon expiration of the time period, deactivates the received PRL.

Systems and related methods include node directed management of multicast traffic within a wireless mesh network. A wireless mesh network may include a plurality of mesh nodes and a central server in communication with at least one of the mesh nodes of the plurality of mesh nodes. The central server may be configured to generate one or more rules for at least one of the mesh nodes to instruct a change in a pre-routing parameter in a packet header based on received channel state information. The central server may include a rules-based engine configured to generate and convey one or more traffic shaping rules in response to sensing traffic conditions. The position of received multicast packets in a packet order may be modified.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving from a plurality of publishers messages of a first channel of a plurality of distinct channels wherein each channel comprises an ordered plurality of messages, storing messages of the first channel in one or more first buffers according to the order, each first buffer having a respective time-to-live, for one or more connections, determining a respective sampling rate based on a data type of the first channel and a determined latency of the connection, receiving from a subscriber through a first connection a request for messages of the first channel, selecting messages in the first buffers according to the order and the sampling rate, and sending the selected messages using the first connection to the subscriber according to the order.

A method for automatic configuration of a communication network includes: generating a request message, the request message including a communication address associated; transmitting the generated request message as a broadcast message to a plurality of computing devices using a predefined user datagram protocol (UDP) port, the message being broadcast with a predetermined time to live; receiving agreement messages from computing devices transmitted by the respective computing device using the predefined UDP port, each agreement message including a communication address associated with the respective computing device and a specified transmission control protocol (TCP) port; identifying at least one of the one or more agreement messages for establishment of communication; and establishing a communication connection to the computing device associated with each identified agreement message using the specific TCP port.

A system, process, and computer-readable medium for updating an application cache using a stream listening service is described. A stream listening service may monitor one or more data streams for content relating to a user. The stream listening service may forward the content along with time-to-live values to an application cache. A user may use an application to obtain information regarding the user's account, where the application obtains information from a data store and/or cached information from the application cache. The stream listening service, by forwarding current account information, obtained from listening to one or more streams, to the application cache, reduces traffic at the data store by providing current information from the data stream to the application cache.

In general, techniques are described for extending network connectivity software utilities, such as traceroute, to provide complete visibility into a network topology between a source device and a destination device, even when an intermediate network device may be actively utilizing multiple network links when forwarding packets toward the destination. In one example, a network device coupled to a plurality of paths and positioned between a source network device and destination network device may receive a traceroute packet. The network device may also, for each of the plurality of paths, modify a payload of the traceroute packet to include a respective identifier for a corresponding path of the plurality of paths to construct a respective modified traceroute packet for the corresponding path. The network device may also forward the respective modified traceroute packets on the corresponding paths.

A method for establishing a stream in a Time-Sensitive Networking (TSN) network, wherein a request message is sent by a stream subscriber to a Domain Name System (DNS) server, upon which entries are stored that each comprise a stream identifier of a first type assigned to a stream, and a stream identifier of a second type that is different from the first type and is assigned to the respective stream, and the specification of a predefined type exclusively used for, or forms these types of entries, where the request message comprises a stream identifier of the first type and the predefined type known to the at least one stream subscriber, where the stream subscriber receives a response message from the DNS server, which contains a stream identifier of the second type belonging to the stream, and where the stream subscriber logs on to the stream using the stream identifier obtained.

An improved traceroute mechanism for use in a label-switched path (LSP) is provided by (a) receiving, by a device in the LSP, an echo request message, wherein the echo request includes a label stack having a least one label, and wherein each of the at least one label has an associated time-to-live (TTL) value; (b) responsive to receiving the echo request, determining by the device, whether or not the device is a penultimate hop popping (PHP) device for the outermost label of the label stack; and (c) responsive to determining that the device is the PHP device for the outermost label of the label stack, (1) generating an echo reply message corresponding to the echo request message, wherein the echo reply message is encoded to indicate that the device is the PHP device for the outermost label of the label stack, and (2) sending the echo reply message back towards a source of the echo request message. Responsive to receiving the echo reply message by the ingress of the LSP defined by the outermost label of the label stack, the ingress may (a) determine whether or not the received echo reply message was sourced from the PHP of the LSP defined by the outermost label of the label stack, and (b) responsive to a determination that the received echo reply message was sourced from the PHP of the LSP defined by the outermost label of the label stack, (1) generate a next echo request in which the TTL value associated with the outermost label in the label stack is increased and in which the TTL value associated with a next to outermost label, if any, in the label stack is incremented, and (2) send the next echo request message on the LSP defined by the outermost label of the label stack.

Systems and methods are disclosed for determining a topology of a network comprising a plurality of intermediary devices and intermediary paths. One method includes transmitting probes having a TTL value with a destination set to a destination device; receiving, for each probe transmitted, a response including an IP address of a responding device; determining whether more than one responding device has responded to the probes; determining whether more than one responding device has been found for two previous transmissions of probes when more than one responding device has responded to the probes; and transmitting, for each more than one responding device, probes having a decreased TTL value with a destination set to one of the IP addresses of the more than one responding devices, when more than one responding device has been found for two previous transmissions.
