Abstract: A communication method is suitable for use in a network architecture including using a software defined network (SDN) protocol and a legacy network protocol, and includes the following steps. A first sub-domain manage unit of a first SDN sub-domain receives a connection request message corresponding to a multicast source from a client. The first sub-domain manage unit transmits a join request message to a main router of a legacy network domain connected to the first SDN sub-domain when determining that the multicast source is not in the first SDN sub-domain. The first sub-domain manage unit transmits the connection request message to a first domain manage unit of a first SDN domain when the main router determines that the multicast source is not in the legacy network domain. A communication path is established between the client and the multicast source when a location of the multicast source is obtained.

Abstract: The disclosure provides a streaming service system, a streaming service method and a controller thereof The streaming service system includes a plurality of switch nodes, a plurality of surrogate servers, a content management apparatus and a controller. The switch nodes are connected, and the surrogate servers are respectively connected to one of the switch nodes. The controller is connected to the switch nodes and communicates with the content management apparatus. The content management apparatus provides server information of the surrogate servers to the controller. When a first client apparatus is joined to a streaming group, the content management apparatus informs the controller. Further, the controller selects a first surrogate server from the surrogate servers, and sets at least a portion of the switch nodes to adjust a multicast tree. The first surrogate server transmits streaming packets to the first client through a first transmission route of the multicast tree.

Abstract: The session-aware NAT traversal method is used to establish network communication between two hosts, wherein a first and a second host are located behind a first and a second NAT router, respectively. First, these hosts conduct a standard NAT traversal to establish a session. Then, the second host sends a registration request message to the first NAT router for session registration. Upon receiving the registration request message, the first NAT router generates a session ID for this session and replies to the second host. As the second host moves to a private network behind a third NAT router, the second host only needs to send a new registration request message with the session ID to the first NAT router. The first NAT router observes a new mapped address of the second host and allows inbound traffic from the new mapped address without further NAT traversal.
