An Internet network architecture for multi-service aggregation and access

Abstract

The invention discloses an Internet network framework for converging and accessing multiple services. The framework comprises a mobile network service client, a fixed network service client and the Internet, wherein data traffic of both the mobile network service client and the fixed network service client is converged to an MSG-U to access the Internet, a CDN including videos and other hot spot content sources is submerged to a convergence DC from a core IDC, and accesses an MSG-U, so that more than 70% traffic is ended at the CDN connected with the MSG-U, and the other traffic is uploaded via a core layer CR; a mobile network service accesses an S / PGW-U via a local UNT access ring and a UTN convergence ring in sequence to complete packaging of a mobile service request, and is converged to the MSG-U to access the Internet, so that hierarchy of a network is greatly reduced; the fixed network service client can access the MSG-U via an SW to forward data, and then access the Internet via the MSG-U.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to an Internet network architecture for multi-service convergence and access. Background technique [0002] In the 4G era, applications such as high-definition video and online games put forward high requirements on network delay. With the advent of the 5G era, emerging industries and services such as telemedicine, VR / AR, etc. have almost stringent requirements on network delay. Low-latency networks have become the development direction that operators are concerned about. [0003] With the rapid growth of 4G users and traffic, the current centralized deployment of S / PGW (mobile network data service gateway) and the multi-layer network architecture of the bearer network cannot meet the large bandwidth requirements of users. When the network bandwidth doubles, the demand for network expansion increases geometrically. By optimizing the current centralized deployment of S / PGW (Mobile Netwo...

AI Technical Summary

Problems solved by technology

This type of strongly coupled access method cannot realize the separation of the control plane and the forwarding plane

The tight coupling of PPPoE forwarding and control makes it impossible for BNG to separate control and forwarding

[0015] The existing S / PGW (mobile network data business service gateway) and CDN content sources are deployed in a centralized manner across the province, placed in the provincial core computer room, and users access the transmission of large-bandwidth, low-latency services (such as games and high-definition video) Long distance, many forwarding hops, packet loss and congestion during hot spots, resulting in extended access time, poor user experience, and high expansion costs
