Abstract: A system transports a plurality of UDP datagrams from a sending application to a receiving application by creating a TCP tunnel between a TCP sending-end and a TCP receiving-end, encapsulating the datagrams in TCP packets at the TCP transmitting-end, transmitting the TCP packets via the TCP tunnel to the TCP receiving-end over a network using a TCP/IP protocol, and extracting the datagrams from the TCP packet and forwarding the extracted datagrams to the receiving application. The TCP tunnel may provide the same delay and responsiveness as UDP protocol. The TCP receiving-end may detect when a packet is missing and request retransmission when a packet is missing, so that the TCP sending-end retransmits the missing packets. The transmitting of TCP packets to the TCP receiving-end continues when the receiving-end detects a missing packet, so that there is no lag in the forwarding of the extracted datagrams. Retransmitted packets may be discarded.

Abstract: In one embodiment, associated differential processing of decapsulated packets is performed using Service Function Instances (SFIs) identified by Service Function Values (SFVs) derived from their encapsulating transport packets. By using different SFVs associated with different processing policies within a same processing context, one embodiment performs differential processing of streams of packets (arriving in transport packets) as identified by the particular SFV obtained from each particular transport packet. In other words, the processing policy identifies processing performed on the corresponding decapsulated original packet, not processing of the transport packet. Thus, if the original packet is an Internet Protocol (IP) packet, the SFI identifies Layer 3 processing that is performed on the original IP packet. Additionally, one embodiment uses a route advertising protocol (e.g., Border Gateway Protocol) to distribute associations between different SFVs and different addresses in a processing context (e.

Abstract: Described embodiments provide systems and methods for tunneling data packets to a server. A computing device can include a processor and a network interface. The processor is configured to execute a network service, a local application, and a virtual private network (VPN) application. The network service can receive a packet from the local application for transmission via a VPN tunnel, the packet comprising a source address of the computing device and a source port associated with the local application. The network service can determine that the packet matches a first tunnel filter. The network service can encapsulate, responsive to the determination that the packet matches the first tunnel filter, the packet with the header comprising a localhost destination address and a destination port associated with the VPN application. The network service can provide the encapsulated packet to the VPN application.

Abstract: Path MTU determination in Generic Routing Encapsulation (GRE) tunnel is presented. A source network device transmits, to a destination network device that is a second endpoint of the GRE tunnel, multiple GRE encapsulated packets that include multiple inner packets respectively, where each inner packet has an inner header used to deliver that inner packet to the source network device and a different payload, and where each of these GRE encapsulated packets has a different size. The source network device receives a first portion of the inner packets from the destination network device and does not receive a second portion of the inner packets. The source network device determines a path MTU to the destination network device based on the size of the GRE encapsulated packet with a largest size for which a corresponding inner packet is received at the source network device from the destination network device.

Abstract: Techniques for a selection or reselection a user-plane path in a mobile network are disclosed herein. A user-plane gateway (GW-U) can be configured to decode a packet received from a control plane gateway (GW-C) in a packet data network gateway (PGW) to determine a forwarding policy. Additionally, the GW-U can decode, from an evolved node B (eNB), an internet protocol (IP) packet having a header field. Furthermore, the GW-U can determine a user-plane path for the IP packet based on a comparison of the header field and the forwarding policy. Based on the determined user-plane path, the GW-U can forward the IP packet to a local application server (AS), encapsulate and forward the IP packet to the PGW, or discard the IP packet. Moreover, the GW-U can encode the IP packet for transmission based on the determined user-plane selection.

Abstract: Example implementation relates to a method for establishing a dynamic VPN tunnel between branch gateway devices based on metric data. A branch orchestrator receives metric data from VPNC device. The metric data includes data center bandwidth and processor utilization of the VPNC device. The metric data is derived from the traffic being routed via the VPNC device. When the metric data associated with traffic between a first branch gateway device and a second branch gateway device is above a Service Level Agreement (SLA), a dynamic branch to branch VPN tunnel is established to route the traffic between the first branch gateway device and the second branch gateway device. The VPN tunnel between the branch gateways can be teared when the load at the VPNC device reduces.
