Abstract

The disclosure discloses a method of establishing a traffic engineering tunnel and a device. The method comprises: a bit indexed explicit replication (BIER) node obtains a traffic engineering (TE) path of a TE tunnel having a predefined traffic volume; the BIER node interacts, using a predefined signaling, with another BIER node on the TE path, to establish an TE message for establishing the TE tunnel; and the BIER node establishes, according to the TE messages, the TE tunnel.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for establishing a traffic engineering tunnel. Background technique [0002] With the rapid development of software-defined network (Software Defined Network, referred to as SDN) technology and network function virtualization (referred to as Network Function Virtualization, referred to as NFV) technology in recent years, network deployment is more and more controllable and complex The degree is also getting higher and higher. For example, for intermediate networks such as core networks and aggregation networks, in order to adapt to different services and meet different deployment requirements, the control methods are becoming more and more complicated. As another example, for multicast applications such as multicast virtual private network (MVPN, MVPN for short) and interactive network television (IPTV), the number of intermediate network node states require...
