A method is disclosed, comprising: receiving a first and a second Internet Protocol (IP) packet at a mesh network node; tagging the first and the second IP packet at the mesh network node based on a type of traffic by adding an IP options header to each of the first and the second IP packet; forwarding the first and the second IP packet toward a mesh gateway node; filtering the first and the second IP packet at the mesh gateway node based on the added IP options header by assigning each of the first and the second IP packet to one of a plurality of message queues, each of the plurality of message queues having a limited forwarding throughput; and forwarding the first and the second IP packet from the mesh gateway node toward a mobile operator core network, thereby providing packet flow filtering based on IP header and traffic type.

Systems, methods, and computer-readable media for annotating process and user information for network flows. In some embodiments, a capturing agent, executing on a first device in a network, can monitor a network flow associated with the first device. The first device can be, for example, a virtual machine, a hypervisor, a server, or a network device. Next, the capturing agent can generate a control flow based on the network flow. The control flow may include metadata that describes the network flow. The capturing agent can then determine which process executing on the first device is associated with the network flow and label the control flow with this information. Finally, the capturing agent can transmit the labeled control flow to a second device, such as a collector, in the network.

Methods and apparatus for efficient data transfer within a user space network stack. Unlike prior art monolithic networking stacks, the exemplary networking stack architecture described hereinafter includes various components that span multiple domains (both in-kernel, and non-kernel). For example, unlike traditional “socket” based communication, disclosed embodiments can transfer data directly between the kernel and user space domains. Direct transfer reduces the per-byte and per-packet costs relative to socket based communication. A user space networking stack is disclosed that enables extensible, cross-platform-capable, user space control of the networking protocol stack functionality. The user space networking stack facilitates tighter integration between the protocol layers (including TLS) and the application or daemon. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack).

Method and computing devices for enforcing packet order based on packet marking. Upon occurrence of a link failure, a first device reallocates traffic initially forwarded through the failed link to an alternative link and marks the reallocated traffic with a first flag. Upon recovery of the failed link, the reallocated traffic is forwarded again through the recovered link and marked with a second flag different from the first flag. A second device calculates a reference inter-packet time for received traffic marked with the first flag. For received traffic marked with the second flag, the second device calculates a current inter-packet time. The current inter-packet time is compared with the reference inter-packet time, to determine if the traffic marked with the second flag shall be forwarded immediately or if the forwarding shall be delayed.

A method for accelerating TCP/UDP packet switching. The method involves determining whether exception processing is necessary; if not, the packet is forwarded to a special stack for expedited processing. Packets requiring exception processing are forwarded to the conventional stack.

A wireless communication device transfer a high-priority message with a high-priority Quality-of-Service (QoS). Device circuitry receives a request for the high-priority message, and in response, signals a radio to wirelessly attach to a wireless network using a high-priority-attachment Establishment Cause. The circuitry generates a Session Initiation Protocol (SIP) message that includes the high-priority message and that indicates the high-priority-attachment Establishment Cause. The radio wirelessly attaches to the wireless network using the high-priority-attachment Establishment Cause. The radio wirelessly transfers the SIP message that indicates the high-priority-attachment Establishment Cause and that includes the high-priority message to the wireless network. The wireless network transfers the SIP message to a message network using the high-priority QoS responsive to the high-priority-attachment Establishment Cause used for wireless attachment. The message network transfers the high-priority message using the high-priority QoS responsive to the high-priority-attachment Establishment Cause in the SIP message.

Systems, methods, and computer-readable media for updating configurations in sensors deployed in multi-layer virtualized environments. In some examples, a system can track information of sensors and collectors in the network. In response to determining that a specific collector becomes unavailable (e.g., the specific collector is down, offline or becomes unsupported), the system can determine affected sensors corresponding to the specific collector, determine a new collector among active collectors of the network for each of the affected sensors, and dynamically update configuration and settings of the affected sensors to maintain proper collector-to-sensor mappings and other settings on the affected sensors.

Methods and apparatus for dynamic packet pool configuration in networking stack architectures. Unlike prior art monolithic memory allocations, embodiments of the present disclosure enable packet pools associated with non-kernel space applications to dynamically allocate additional memory allocations to a given non-kernel space application, or conversely, de-allocate memory allocations to a given non-kernel space application. Variants also disclose the splitting up of a memory allocation into device accessible portions and kernel accessible portions. Other variants disclose sizing certain segment allocations so as to be a multiple of a physical address page size. Such a variant enables a single input/output (I/O) bus address lookup for the given segment so as to minimize look up costs associated with an I/O lookup for the given segment.

A switch receiving Ethernet packets is disclosed, including TCP packets and/or non-TCP packets. The Ethernet packets are forwarded to at least two ports by forwarding each TCP Present application relates to a switch receiving Ethernet packets, including TCP packets and/or non-TCP packets, and forwarding the Ethernet packets to at least two ports by forwarding each of the TCP packets to any one of the at least two ports and forwarding each stream of non-TCP packets to one corresponding port of the at least two ports.
