Inter-node communication processing method and route determination node

Abstract

An embodiment of the present invention provides a communication processing method between nodes and a routing determination node. The method includes the routing determination node determining the global virtual identifier of the target end node, and the routing determination node is a centralized control unit or an entry point in a software-defined network. Or a function node, the target end node is the target end node of the routing path for transmitting interface data, and the global virtual identifier is used to indicate the interface information and network information of the target end node; the routing determination node according to the global The virtual identifier determines the network parameters and routing parameters of the processing nodes on the routing path, and determines the routing path for interface data transmission in the new network architecture according to the global virtual identifier of the target end node.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a communication processing method between nodes and a route determination node. Background technique [0002] In the core network (Evolved Packet Core, EPC for short) network architecture defined in the existing 3rd Generation Partnership Project (3GPP for short) agreement, a Mobility Management Entity (MME for short) is Control plane function, public data gateway (PDN Gateway, referred to as PGW) / serving gateway Serving Gateway, referred to as SGW) is the bearer plane function, serving GPRS support node (Servicing GPRS Support Node, referred to as SGSN), MME, PGW, SGW and other network elements They all exist as independent physical entities. Taking PGW as an example, PGW integrates many data plane functions, such as mobile IP, data packet filtering, GPRS Tunneling Protocol (GPRS Tunneling Protocol, GTP for short) tunnel management, security, billing, etc. ...

[0002] In the core network (Evolved Packet Core, EPC for short) network architecture defined in the existing 3rd Generation Partnership Project (3GPP for short) agreement, a Mobility Management Entity (MME for short) is Control plane function, public data gateway (PDN Gateway, referred to as PGW) / serving gateway Serving Gateway, referred to as SGW) is the bearer plane function, serving GPRS support node (Servicing GPRS Support Node, referred to as SGSN), MME, PGW, SGW and other network elements They all exist as independent physical entities. Taking PGW as an example, PGW integrates many data plane functions, such as mobile IP, data packet filtering, GPRS Tunneling Protocol (GPRS Tunneling Protocol, GTP for short) tunnel management, security, billing, etc. , there are two main problems: one is that these functions are implemented in a physical box in a tightly coupled manner, which is not conducive to the introduction of new functions; wasted during high traffic and congested during high traffic

[0004] However, in this new network architecture, if there are data paths for different communication objects, how to correctly route and process the various interface data generated during the communication process, and reach the target end node, the existing technology has not proposed a solution method
