  • Patent number: 10742564
    Abstract: Device, system, and method of Voice over Internet Protocol (VoIP) communications, and particularly of Real Time Protocol (RTP) communication. In order to improve quality-of-service or quality-of-experience for a group of VoIP calls that are served by a VoIP router, each VoIP transmitter implements and adds a pseudo-random waiting-period prior to transmitting each outgoing RTP packet, or otherwise re-orders or mixes or shuffles the order of channels of RTP packets that are buffered or queued for transmission. Accordingly, no particular VoIP channel suffers from repeated drops of its RTP packets at the VoIP router. Additionally, VoIP network analyzers operate to measure the overall VoIP network overuse, or the average RTP packet loss rate of multiple VoIP channels, based on measuring RTP packet loss rate of a single VoIP channel which enforces a random pre-transmission waiting-period.

  • Patent number: 10693796
    Abstract: Embodiments provide a system and method for network tracking. By using packet capture applications having a flow identifier and a time stamper, one or more raw packets from one or more packet flows intercepted from a network can be tagged with a unique identifier and timestamp that can later be used to aggregate packet flows that have been analyzed by one or more capture applications. The unique identifier can relate to the network interface of the particular capture application and can also have an increasing value, where the increase in value can be monotonic. Later capture applications, while capable of generating secondary timestamps, can disregard those secondary timestamps for the primary timestamp of the first capture application in order to remove complications arising from latency issues.

  • Patent number: 10694443
    Abstract: A method of operation of a wireless communication device to perform handover in a wireless communication system is provided. The wireless communication device performs a beam tracking procedure for one or more neighbor cells to provide, for each neighbor cell, a list of tracked beams for the neighbor cell. The wireless communication device receives a handover command from a source radio access node that instructs the wireless communication device to perform a handover from a source cell served by the source radio access node to a target cell served by a target radio access node. The target cell is one of the neighbor cells for which the beam tracking procedure is performed. The wireless communication device selects a beam of the target cell from the respective list of tracked beams based on random access resource configuration and/or a quality threshold and performs random access on the selected beam.

  • Patent number: 10680851
    Abstract: The present disclosure provides a method, apparatus, and device for PPTP VPN based access acceleration. A PPTP VPN system includes a client-side, a first server, a VPN server, and a second server cluster supporting a GRE protocol connected between the first server and the VPN server. When the client-side starts an accelerated access, the first server receives a first PPTP message and a first GRE message from a same client-side, and encapsulates the first GRE message. An encapsulated first GRE message and the first PPTP message are send to a same second server. The first GRE message is encapsulated and the source addresses of the first GRE message and the first PPTP message are changed. Therefore, the reliability of the transmission can be achieved. Reverse transmission is no difference. The present disclosure accelerates the access speed of the VPN server and improves the access quality of the user.

  • Patent number: 10623263
    Abstract: Technologies for autonegotiation of communications operational modes over copper cable include a network port logic having a communication link coupled to a remote link partner. The network port logic may start an autonegotiation protocol upon reset, when the link is broken, or upon manual renegotiation. The network port logic transmits an autonegotiation page to the remote link partner that indicates single-lane communications ability over copper cable. The network port logic receives an autonegotiation page from the link partner indicating single-lane communications ability over copper cable. If the network port logic and link partner have a common single-lane communication ability, the link may be activated. The autonegotiation pages may be base pages or next pages. The single-lane communication ability may be indicated by one or more bits of the autonegotiation pages. The link may be established at 1 gigabit or 10 gigabits per second. Other embodiments are described and claimed.

  • Patent number: 10609546
    Abstract: A device can receive, from a node in a core network, application identifiers associated with applications accessible by a first user device. The application identifiers can be associated with latency requirements. The device can obtain, from the first user device, a first packet associated with a first packet flow. The device can compare information regarding the first packet flow, and the application identifiers to determine that the first packet is destined for a low-latency application having a specified latency range. The device can identify a first low-latency bearer that satisfies the specified latency range associated with the low-latency application. The device can map the first packet flow to the first low-latency bearer, and communicate packets, associated with the first packet flow, using the first low-latency bearer. The packets can include data packets communicated between an entity hosting the low-latency application and the first user device, while bypassing the core network.
