A method of performing a multimedia communication session over a communication link using Transmission Control Protocol (TCP) and over a communication link using User Datagram Protocol (UDP), including the acts of: receiving a request, over the TCP link, to register from a client terminal located within a private network; a probe data packet to the client terminal, over the TCP link, requesting to send a data packet over the UDP link; and receiving a data packet from the client terminal that contains information relating to an address of the client terminal and a dynamic port over which the multimedia communication session is to be established.

The invention discloses a transmission method used for an operation management and maintenance message of an Ethernet. The method includes the following steps: an original node transmits an OAM message, and a receiving node judges whether a connection maintenance termination address is matched with current node address; and if matched, the message is terminated; otherwise, the message is transmitted according to a router mark. The invention also discloses the transmission method used for an operation management and maintenance message of an Ethernet. The method includes the following steps: the first node receives an OAM message; the first node transmits an OAM returning message; the second node transmits the OAM returning message. The invention also discloses the transmission system used for the operation management and maintenance message of the Ethernet, the transmission node of the operation management and maintenance message of the Ethernet and the receiving node of the operation management and maintenance message of the Ethernet. The OAM message of the invention is transmitted according to the monitored MAC of the service router mark and a VLAN ID message, and is able to transmit the OAM message in a PBT network.

The present invention relates to a communications system (1) for handling communications sessions, for example multimedia calls or voice calls. The communications system (1) comprises a local terminal (10), an external server (40), a proxy interface agent (PIA) (11) between the terminal (10) and a shared network (20). The communication means includes a NAT function (32) through which the communications session must pass. The communications session is carried over the network (20) over one or more logical channels between the terminal (10) and the external server (40), during which the first NAT function (32) applies network address mappings on the terminal's transport addresses (14). The PIA (11) acts on behalf of the terminal (10) in communications with the external server (40), and establishes a logical channel on an outbound connection to the server that serves as a control channel between the PIA (11) and the server (40). The PIA (11) establishes dynamic outbound connections to the server (40), and in response to a request from the server or in response to a request from the PIA itself (11), makes one or more associations between the terminal's transport address(es) (14) and identifiable logical channel(s) between the PIA (11) and the server. These identifiable logical channel(s) are established on one or more of the dynamic outbound connections from the PIA (11) to the server (40).

The invention provides a forwarding method for a multicast message in a virtual private local area network (LAN) service (VPLS), and service provider edge equipment (PE). Through the establishment of a virtual link (PW) logic interface, a second layer multicast protocol is introduced into a second layer control plane. At the view angle of the second layer control plane, the PW logic interface is the same as the common second layer Ethernet interface and can participate in the calculation of various application protocols of the control plane. In the invention, the established PW logic interface is taken as the second layer Ethernet interface to operate the second layer multicast protocol, a corresponding multicast forwarding table entry is established, and the multicast message is forwarded according to the established multicast forwarding table entry, so that the multicast message is correctly forwarded, the burden of the PE equipment is reduced and the bandwidth resources of a public network are further saved.

The invention provides a service data forwarding method based on a service function chain and an Overlay network system. The method comprises the following steps: a classifier generates an NSH according to forwarding path information of a service message, packages the NSH in an SFC control message, and forwards the SFC control message in an SFC domain based on the NSH; And the NVE packages the received SFC control message, an NSH is packaged in the VxLAN message, and the VxLAN message is sent to the NVE of the next hop through the VxLAN tunnel. According to the method, the Overlay network system and the SFC service providing method for providing the VDC service under the scene that the NVE node is separated from the SFF, so that the SFC flow forwarding processing does not depend on a network structure and topology, and the dynamic deployment migration of service function nodes of a data center is met; A new processing mechanism is defined for the classifier, the SFF and the NVE, and the SFC service can be correctly forwarded; NSH message processing is added in the SFC service, the implementation is simple, and hardware change is not needed.

The invention provides a traffic forwarding method in cloud computing, equipment, a computer device and a readable medium. The method comprises the steps of receiving traffic requests of source sidesfor accessing target LB (Load Balancer) instances, wherein the traffic requests comprise identification information for identifying the target LB instances; bearing the identification information of the target LB instances in TCPOption, and establishing TCP (Transmission Control Protocol) connection with LBs of networks based on the TCPOption in which the identification information of the target LB instances is borne; and forwarding the traffic requests to the LBs of the networks based on the TCP connection, thereby enabling the LBs of the networks to forward the traffic requests to corresponding real servers according to the identification information of the target LB instances in the TCPOption. According to the method, the equipment, the computer device and the readable medium, in a scene that the LBs based on the same group of completely same networks serve a plurality of LB users, the traffic can be forwarded accurately; the services of various LB users do not need to be isolated,the realization is very simple and convenient; and a resource utilization rate of the LBs of the networks can be effectively improved.

The disclosure describes method and system for forwarding frames of a flow via a layer 2 forwarder and manipulator (L2FM) for improving network utilization and improving users experience by reducing the latency associated with the flow. When a new flow is identified, forward control information for frames of the new flow is obtained. The forward control information can include re-writing of at least one field in an original header of the frames of the new flow. At least one field in an original header of the frames of the new flow is manipulated according to the obtained forward control information, and the manipulated frames of the new flow are forwarded accordingly.

The invention provides an IGMP snooping processing method and system during STA roaming. The method comprises that when an STA roams from a first AP to a second AP, the second AP obtains the MAC address of the STA; if the MAC address of the STA is found in AC, a multicast MAC address corresponding to the MAC address of the STA is obtained, and an IGMP member relation message including the MAC address of the STA and the corresponding multicast MAC address is established and sent to an IGMP server; a switch obtains the multicast MAD address if finding the IGMP member relation message by monitoring, and according to the port, receiving an IGMP query message, of the switch, a <multicast address is formed, and a port>entry in the IGMP query message is received and added to an IGMP snooping route port table. The multicast message can be rapidly and accurately forwarded to the STA which carries out roaming in the roaming scene.
