EPC firewall disaster recovery networking system and data transmission method based on the system

Abstract

The invention discloses an EPC firewall disaster recovery networking system and a data transmission method based on the system. At least one pair of EPC core switches is connected through an interconnection interface, and the specific connection mode is the second EPC in one EPC core switch pair. The core switch is interconnected with the third EPC core switch in another EPC core switch pair, and the second EPC core switch is configured with a static route to the local area network where the third EPC core switch is located, and the static route is connected to the second EPC core switch according to The private network IP address configuration of the port of the third EPC core switch, and the routing next hop points to the third EPC core switch, and the third EPC core switch is configured with a static route to the local area network where the second EPC core switch is located, the static route According to the private network IP address configuration of the port of the second EPC core switch connected to the third EPC core switch, and the next hop of the route points to the second EPC core switch. The system can solve the problem of inability to recover disasters 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...
