EPC firewall disaster-tolerant networking system and data transmission method based on same

Abstract

The invention discloses an EPC firewall disaster-tolerant networking system and a data transmission method based on the same. At least one pair of EPC core switchers are connected with each other through an interconnection interface, and the specific connection mode is that the second EPC core switcher centered by one EPC core switcher is connected with a third EPC core switcher centered by the other EPC core switcher; the second EPC core switcher is provided with a static route which is led to a local area network where the third EPC core switcher is located, wherein the static route is configured according to a private network IP address of a port of the third EPC core switcher connected with the second EPC core switcher, and the next hop of the router points to the third EPC core switcher; the third EPC core switcher is provided with a static router which arrives at the local area network where the second EPC core switcher, wherein the static route is configured according to a private network IP address of a port of the second EPC core switcher connected with the third EPC core switcher, and the next hop of the route points to the second EPC core switcher. The system can solve aproblem that the disaster tolerance cannot be achieved between firewall pairs.

Description

technical field [0001] The invention relates to the core network field of mobile communication technology, in particular to an EPC firewall disaster recovery networking system and a data transmission method based on the system. Background technique [0002] In order to meet the EPC (4G core network) system load sharing, the EPC network uses MME POOL (MobilityManagement Entity pool mobile management node pool) and SAE-GW POOL (Serving Gateway and PDNGateway POOL service and PDN gateway pool). At the same time, for network security, the equipment of MME POOL and SAE-GW POOL needs to be distributed in different LANs, so as to prevent the failure of LAN networking equipment or related networks to cause total blockage of POOL services. [0003] In the EPC network, the firewall is responsible for IP address reuse and border protection, and is an indispensable part of the core network. With the rapid development of 4G networks and the extensive use of services such as WeChat red e...
