Description

混合网络中的报文分发方法、装置和***Message distribution method, device and system in hybrid network 技术领域Technical field
本发明涉及通信领域，尤其涉及混合网络中的报文分发方法、装置和***。The present invention relates to the field of communications, and in particular, to a message distribution method, apparatus, and system in a hybrid network.
背景技术Background technique
混合网络(Hybrid网络)在当前成为一种趋势，Hybrid网络是指将不同的物理通道绑定在一起以提供更高的传输带宽的网络。在接入网领域，Hybrid G.fast作为一种Hybrid网络，受到运营商的广泛青睐。Hybrid networks (Hybrid networks) are currently becoming a trend. Hybrid networks are networks that bind different physical channels together to provide higher transmission bandwidth. In the field of access networks, Hybrid G.fast, as a Hybrid network, is widely favored by operators.
G.fast采用TDD(Time Division Duplex，时分双工)技术，与VDSL2(Very-high-speed Digital Subscriber Line 2，超高速数字用户线2)相比，G.fast具有更加灵活的上下行速率配比。G.fast通过双绞线连接在短距离内可以实现超过1G比特的超高速宽带接入，接入速率是VDSL2接入速率的十倍，因而可以不需要光纤就可以实现千兆超高速接入。G.fast uses TDD (Time Division Duplex) technology. Compared with VDSL2 (Very-high-speed Digital Subscriber Line 2), G.fast has more flexible uplink and downlink rate matching. ratio. G.fast can achieve ultra-high-speed broadband access of more than 1Gbit in a short distance through a twisted pair connection, and the access rate is ten times that of the VDSL2 access rate, so that Gigabit ultra-high-speed access can be realized without using an optical fiber. .
Hybrid G.fast是指将G.fast物理通道和其他物理通道绑定，不同的物理通道占用不同的频段，为了降低不同物理通道之间的串扰，通常采用频分复用的方式，如0M-2.2M用作ADSL、2.2M-17M用作VDSL2、23M-106M用作G.fast等。由于VDSL2可以承载最高120Mbps的流量，G.fast可以承载最高1Gbps的流量，为了充分利用频谱，当某个用户使用G.fast接入时，除了使用G.fast通道外，还可以通过VDSL2通道来承载数据流量，报文在G.fast通道与VDSL2通道上进行负荷分担。具体的，上行方向CPE(Customer Premises Equipment，用户驻地设备)将报文分发到G.fast通道与VDSL2通道上，由汇聚设备合并；下行方向在汇聚设备上将报文分发到G.fast通道与VDSL2通道上，由CPE将业务流合并。Hybrid G.fast refers to the binding of G.fast physical channels to other physical channels. Different physical channels occupy different frequency bands. In order to reduce crosstalk between different physical channels, frequency division multiplexing is usually adopted, such as 0M- 2.2M is used as ADSL, 2.2M-17M is used as VDSL2, 23M-106M is used as G.fast, and the like. Since VDSL2 can carry up to 120Mbps traffic, G.fast can carry up to 1Gbps of traffic. In order to make full use of the spectrum, when a user uses G.fast access, in addition to using the G.fast channel, it can also be accessed through the VDSL2 channel. Carrying data traffic, the packets are load-sharing on the G.fast channel and the VDSL2 channel. Specifically, the CPE (Customer Premises Equipment) distributes the packet to the G.fast channel and the VDSL2 channel, and the aggregation device merges the packet. The downlink device distributes the packet to the G.fast channel on the aggregation device. On the VDSL2 channel, traffic flows are merged by the CPE.
在采用G.fast通道和VDSL2通道负荷分担时，负责合并的设备需要知道分发设备所采用的负荷分担方式，这样才能正确的合并报文，然而当前并没有这种机制。When using G.fast channel and VDSL2 channel load sharing, the device responsible for merging needs to know the load sharing mode used by the distribution device, so that the packets can be correctly merged. However, there is no such mechanism at present.
