The disclosure includes a method for establishing a connection with QoS assurance. In the method, a router receives a first IPv6 packet for establishing a first connection, wherein the first IPv6 packet includes a first QoS requirement for the first connection in a hop-by-hop extension header of the first IPv6 packet. Then, the router modifies the first IPv6 packet by setting first information in the hop-by-hop extension header of the first IPv6 packet, where the first information indicates that the router meets the first QoS requirement. Furthermore, the router sends the modified first IPv6 packet to a second router based on a destination IP address of the modified first IPv6 packet.

Quality of service for data transmission

A server implements a method for sending routing information in an Internet exchange point (IXP) network. The server receives control information from a first IXP member via the IXP network and obtains first routing information from the first IXP member via the IXP network, where the control information comprises an identifier of a second IXP member. Based on the first routing information and the control information, the server generates second routing information for the second IXP member, where the second routing information may be identical to the first routing information or a portion of the second IXP member. After the generation, the server sends the second routing information to the second IXP member. With the second routing information, the second IXP member may obtain some routing capability of the first IXP member.

Generic packet encapsulation for virtual networking

Embodiments are provided herein to enable single level network abstraction for a service across one or more domains. The embodiments use a single network ID to identify a service and a corresponding virtual network topology across any number of domains at a physical network. A virtual network topology can be abstracted for each service, based on the physical underlying network topology. A network controller determines, for a service, the virtual network topology within a physical network, and binds the service to the virtual network topology via a virtual network ID, which defines a single forwarding domain of the virtual network topology across the physical network. The virtual network ID is then indicated to the nodes of the virtual network topology, thus enabling the nodes to identify and forward traffic for the service, within the single forwarding domain, between end clients from edge to edge of the physical network.
