IPX是IP报文交换（IP Packet eXchange）的英文简称，IPX为基于已有的GRX框架的演进架构。IPX对GRX的概念进行了扩展，使得固网和移动服务提供商可以在一个更开放和灵活的网络环境中进行互联。 IPX网络具有如下几个特点： 安全的环境：提供了一个和隔离的透明网络。

IP exchange or (IPX) is a telecommunications interconnection model for the exchange of IP based traffic between customers of separate mobile and fixed operators as well as other types of service provider (such as ISP), via IP based Network-to-Network Interface. IPX …

So what is GRX ? GRX = GPRS roaming exchange. Exchanging GPRS and 3G roaming data. Private IP network (separate from the internet). Limited to GSM operator community. ‣ AMS-IX the main GRX peering point globally, interconnecting 25 GRX providers.

grx和ipx有什么区别？ （1）grx是为gprs漫游而设计的，只有移动操作员才能互连。 （2）在ipx中，其设计用于所有ip互连，包括mno，fno （3）grx运输是最好的努力流量，而ipx运输是基于qos的，基于班级的，优先的流量。

Contrary to previous versions of IR.34, GRX is now considered an IPX service which is offered on an IPX Network. The term GRX network is no longer used; however, an entity which only offers the GRX service may refer to itself as a GRX Provider.

GRX is a network used for roaming between mobile network operators, while IPX is a more open and flexible model that applies to various service providers, including fixed network operators, internet service providers (ISPs), and application service providers (ASPs).

GRX是一个专门用于支持GPRS数据漫游的网络架构，它连接了全球各个移动运营商的GPRS核心网，为用户在国际漫游时提供数据服务。 可以说，IPX是一个更广泛的概念，涵盖了各种数据漫游服务，而GRX则是IPX的一部分，专注于支持GPRS数据漫游。

ipx对grx的概念进行了扩展，使得固网和移动服务提供商可以在一个更开放和灵活的网络环境中进行互联。 IPX网络具有如下几个特点： 1、安全的环境：提供了一个和隔离的透明网络。

The IP packet eXchange (IPX) is a global, private, secure, IP network which supports end-to-end quality of service and the principle of cascading interconnect payments (when applicable). In order to provide these features, the IPX can be service aware, unlike the Internet and the GPRS Roaming eXchange (GRX) network. GRX is now considered an IPX
