PACKET FORWARDING METHOD AND APPARATUS, AND NETWORK SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18341630 Titled 'PACKET FORWARDING METHOD AND APPARATUS, AND NETWORK SYSTEM'
Simplified Explanation
This application describes a method and apparatus for packet forwarding in a network system. The method involves the first CPE (Customer Premises Equipment) performing inner and outer encapsulation on a first packet. The inner tunnel is a direct connection between the first CPE and the second CPE, while the outer tunnel passes through a GW (Gateway). The second destination address in the outer encapsulation is the address of the GW. This allows for the establishment of an end-to-end inner tunnel between the first CPE and the second CPE, with the inner tunnel passing through a backbone network via the GW. This enables communication between the first CPE and the GW.
Original Abstract Submitted
Embodiments of this application disclose a packet forwarding method and apparatus, and a network system, and belong to the field of communication technologies. The method includes: When sending a first packet, first CPE may perform inner encapsulation and outer encapsulation on the first packet. The inner tunnel is an end-to-end tunnel between the first CPE and second CPE, and a second destination address in the outer tunnel encapsulation may be an address of a GW. It can be learned that in this application, an end-to-end inner tunnel may be established between the first CPE and the second CPE, and the inner tunnel may pass through a backbone network via the GW and then reach the second CPE on a basis that an outer tunnel is established so that the first CPE and the GW communicate with each other.
