Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the invention will be further described below in conjunction with the drawings and specific embodiments, but the present invention is not limited to following examples.
Present embodiment provides a kind of XDSL data transmission method for uplink, and the Node B in this method need support a plurality of ethernet ports.From a plurality of ethernet ports, select at least two as data transmission port, and the external Modem of each port for selecting, each Modem links to each other with RNC for a link.Node B and RNC send data by the multilink of a plurality of Modem correspondences.Present embodiment is an example with external two Modem, and each external Modem on two ports of Node B forms two links and links to each other with RNC.In the actual networking, if Node B is far away from the RNC distance, then link need link to each other with RNC by go-between.The data network that this go-between is made up of intermediate conveyor equipment, intermediate conveyor equipment may be switch or router.
After the external a plurality of Modem of Node B finish, can adopt following two kinds of data receiver formulas:
Mode 1: load sharing:
The routing table of many equal priority is set up in the base station, the route table items correspondence of these each equal priority different source IP addresss, purpose IP address, port etc. are by being mapped to different data flow the load sharing of realizing data flow on the different routes.
Node B supports the load sharing of IP layer to transmit, and is specially:
Node B flows different upper layer datas, is mapped on the different ethernet ports to send, and concrete corresponding relation is:
Node B is when data flow and transmission map, the route table items that different data flow is corresponding different, but the priority of these list items is identical, because the source IP address that these route table items are corresponding different, purpose IP address, ports etc. are so NodeB can mail to different data flow different ports.Referring to Fig. 2, above behavior example, Node B is mapped to port one with data flow 1, and data flow 2 is mapped to port 2, and data flow 1 and data flow 2 mail to port one and port 2 respectively.
In like manner, RNC also is the same with Node B, RNC is in the data that mail to each Node B, the route table items that different data flow is corresponding different, but the priority of these list items is identical, since the corresponding different source IP address of these route table items, purpose IP address, ports etc. send on the different port of Node B so RNC has just realized different data streams.
Mode 2: link aggregation:
Link aggregation is meant a plurality of ethernet ports is aggregated to together, being used as a port handles, these ports have identical IP address, by LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol) automatically between the realization equipment port trunking do not need user intervention, but also link layer fault that can detection port is finished the polymerization control of link.According to the configuration mode of link aggregation, link aggregation can be divided into manual link aggregation, static link polymerization and dynamic link polymerization.
Under the link aggregation situation, Node B sends data source address and has only one, just has only an IP address, and this point is different with mode 1.Mode 1 time, different ports has different IP addresses, mode 2 times, the port that Node B is different has only an IP address, the different data flow of Node B sends at each port simultaneously, for example: referring to Fig. 3, NodeB is distributed to port one and port 2 with data flow 1, and data flow 2 also is distributed to port one and port 2.The data networking equipment of butt joint also needs to support link aggregation, by link aggregation, guarantees the reliability of docking with Node B.
RNC is different with mode 1 mode 2 times, and mode 2 times, the destination address of the transmission message of RNC has only one, only sends message toward this IP address.
Many Modem scheme that the embodiment of the invention provides owing between Node B and the many Modem many transmission links are arranged, is compared with single-link, has also improved the transmission bandwidth of Node B greatly.And, under the situation of single Modem, have only a link between Node B and the Modem, only on this transmission link, send message, in case this link down just causes whole transmission link to interrupt.And many Modem that the embodiment of the invention provides scheme in case certain bar link down can also be based upon business on other the transmission link, guarantees professional reliability.In addition, the mode that sends datagram can have multiple, such as above-mentioned load sharing, link aggregation etc.
Further perfect as scheme, the embodiment of the invention also provides the scheme of multilink monitoring reliability, guarantees when Modem breaks down, or when Node B and Modem link down, also can guarantee the reliability of XDSL networking, and the assurance business can not interrupted.If in case monitor, judge that certain bar link down, base station and base station controller stop to send message toward this link; To be monitored, judge this link-recovery after, the data of this link send before continue to recover interrupting again.
Node B and RNC will regularly monitor the link of each port.Detection method has: by BFD (BidirectionalForwarding Detection, two-way forwarding detection) control message, Ethernet OAM (Operations, Administrationand Maintenance, Operations, Administration and Maintenance) or PING methods such as (Packet Internet Groper, packet the Internet detectors).Below describe respectively:
