Abstract

The embodiment of the invention relates to an apparatus, a method and a device for communication, and a computer readable storage medium. For example, the method determines whether to use one of a plurality of control protocols for overlay tunnel establishment. Then, tunnel encapsulation parameters for overlay tunnel establishment are obtained based on the determination, and overlay tunnel establishment is performed using the tunnel encapsulation parameters. The overlapping tunnel establishing process is more flexible and efficient.

Description

technical field [0001] Embodiments of the present disclosure generally relate to communication technologies, and more particularly, relate to devices, methods, apparatuses and computer-readable storage media for communication. Background technique [0002] Broadband Forum (BBF) Technical Report (TR) 317 (referred to as BBF TR-317) describes a Network Enhanced Residential Gateway (NERG) connectivity model, the Flat Ethernet Logical Subscriber Link (LSL) model. According to this model, LSL segments between Broadband Network Gateway (BNG) and Virtual Gateway (vG) hosting infrastructure can be established dynamically at runtime. This establishment can be driven by an Authentication, Authorization, and Accounting (AAA) operation, which can be triggered by a Dynamic Host Configuration Protocol (DHCP) request from a Bridging Residential Gateway (BRG). [0003] In the NERG Flat Ethernet LSL model, each BRG and network-based vG located at a customer site can be linked by a unique LS...
