Introduction to Integrated IP Microwave Integrated IP microwave develops from Hybrid radio. Integrated IP microwave can transmit Native E1/STM-1, Native Ethernet, or PWE3 services based on the software settings. settings. Therefore, integrated IP microwave achieves smooth evolution from Hybrid radio (transmitting Native E1 and Native Ethernet services) to Packet radio (transmitting PWE3 services). PWE3 services are also carried by Ethernet frames. An IF board does not separate Ethernet frames carrying Native Ethernet services from t hose carrying PWE3 services. Therefore, integrated IP microwave is essentially Hybrid radio transmitting Native E1 services and Ethernet services. The difference is that Hybrid radio transmits Native Ethernet services, but that IP microwave

transmits Native Ethernet services or PWE3 services.

Principle of Integrated IP Microwave An IF board transmitting integrated IP radio services is connected to the cross-connect unit through the VC-4 bus on the t he backplane, and receives Native TDM services. In addition, the IF board is connected to the packet switching unit through the GE bus and receives Ethernet services. Incoming Ethernet services can be Ethernet frames carrying PWE3 services and Native Ethernet services. The IF board encapsulates Native TDM services and Ethernet services into microwave frames for transmission. Backplane

 Advantages of packet header compression: •

During point-to-point IP microwave transmission, VoIP and video services are short packets. In such short packets, Ethernet MAC header+IP header are large parts of packet headers. If a ffew ew fixed bytes substitute subst itute for Ethernet MAC header+IP header, the transmission efficiency of a radio link is improved significantly, and therefore Ethernet service throughput over microwave is boosted.

•

When L2 Ethernet frame header compression is enabled, the RTN 900 V100R003 has 40% more throughput (500 Mbit/s to 600 Mbit/s) to transmit Ethernet services.

•

When L2 Ethernet frame header compression and L3 IP packet header compression are enabled, the RTN 900 V100R003 has 130% more throughput (900 Mbit/s) to transmit Ethernet services.

Calculating Air-Interface Traffic in the Case of Ethernet/IP Header Compression 

Calculation formula of air-interface traffic in the case of Ethernet/IP header compression Service air-interface bandwidth = [(L + 3 + ROUNDUP((L + En. Len)/128) + En. Len + 2(Enable one) or 3(Enable both) - L2 header compressed - IP header compressed - 2)/(L + 20)] x Service port bandwidth L is service packet length; 3 + ROUNDUP((L + En. Len)/128) is frame encapsulation at air interface; 20 is Ethernet frame interval and preamble; En. Len is encapsulation on RTN equipment. If the service is carried on a QinQ link, the encapsulation overhead is 4; 2 or 3 is the index of Ethernet/IP header compressed in the first f ragment; the length of Ethernet/IP header compressed is based on the compression length of packet at port. Only the MPLS label and layer 2 header can be compressed; 2 is the compression length of FCS. The number of base stations, L, and service port bandwidth are provided by the wireless department. For example, four base stations are mounted to the RTN 950. Ethernet headers are compressed: 6 Mbit/s (128 bytes), 16 Mbit/s (256 bytes). The upstream air-interface bandwidth of the RTN 950 is [(128 + 3 + +22 + +2 - 31 - +3)/(128 + 20)] x 6 x 4 + [(256 + +3 + 2 + +2 - 31 - 2)/(256 + 20)] x 16 x 4 = 82.32 Mb it/s

Dependencies and Limitations of Packet Header Compression on RTN 900 V100R003 NEs

 

 

Packet header compression requires that the settings at the two ends of a radio link be the same. Otherwise, communication fails. Compression information synchronization involves in point-to-point transmission compression information at both ends of a radio link keeps consistent according to the specific feedback f eedback information. In this manner, the receive end restores packet headers based on compression information. To achieve compression information synchronization, the radio link must be reliable. A maximum of 256 streams can be compressed for transmission. Only the newly-developed ISU2/ISX2 boards provide the packet h eader compression function.

Introduction to MPLS Multi-Protocol Label Switching (MPLS) combines c ombines ATM ATM and IP technologies. MultiMulti protocol means multiple Layer 3 protocols such as IPV4 and IPV6. Label switching means switching of labels.

On an MPLS network as shown in this figure, the nodes on the edge are LERs, LERs, the intermediate the intermediate nodes are LSRs. LERs and LSRs fast f ast forward packets based on labels. The path along which the packets are forwarded is an LSP. LSP. In this t his figure, the red line and blue line represent two LSPs. Theoretically, Theoretically, an unlimited number of MPLS labels can be stacked. Actually, Actually, there are up to three layers. The outermost layer is a tunnel label and the second outermost layer is a PW label. Pseudo Wire Emulation Edge to Edge (PWE3) can encapsulate ATM, ATM, TDM, and Ethernet services into PWs for transmission over an MPLS network.

Dependencies and Limitations of MPLS 1. Dependencies IF boards for IP microwave and Ethernet interface boards support MPLS tunnels. 2. Limitations Currently,, MPLS labels can only be configured statically. Currently MPLS tunnels are supported, but IP tunnels and GRE tunnels are not created. Tunnel Tunnel bandwidth limitation is only valid for bandwidth verification verifi cation on the configuration layer, layer, but not for traffic li mit.

Ethernet services, TDM (CES) services, and ATM ATM services can be encapsulated into PWE3 packets and carried on tunnels that are transmitted on an MPLS network.  As shown in this figure, an MPLS network is present between between the NodeBs and the RNC and BSC. The services from the NodeBs are encapsulated into PWE3 packets and then transmitted over tunnels. At the other end of the MPLS network, the PWE3 packets are decapsulated and transmitted to the RNC/BSC.



As shown in the left figure, the SS-PW is used to create cr eate simulation services between the NodeBs and RNC. When a NodeB is added, two end-to-end tunnels must be added on the PSN2 network. As a result, with the increase of NodeBs, the number of the tunnels in the PSN2 network increases sharply.



As shown in the right figure, multiple PWs share a tunnel in the PSN2 network. This is called MSPW.

Introduction to IMA IMA, standing for inverse multiplexing for ATM, ATM, is a technology that demultiplexes the stream of concentrated c oncentrated ATM cells into multiple mul tiple lower-rate links l inks and multiplexes these lower-rate links at the remote end to recover the original stream of concatenated ATM ATM cells. By using this technology, technology, multiple lower-rate lower-r ate links are flexibly and conveniently multiplexed. IMA is used on E1 links or links of other rates r ates to transmit ATM ATM cells. The IMA sublayer is part of the Physical layer, layer, that is, between the Transport Transport layer and the ATM ATM layer. It transparently transmits ATM ATM and higher layer signals.

 As show in the figure, LAG provides the following functions: Increases the bandwidth utilization: utilization: Multiple low-rate links can be multiplexed into a logical highrate link. Dynamically adjusting the bandwidth: bandwidth: After an IMA group is successfully created, the bound links in the IMA group can be dynamically added or deleted. Improving the usability: usability: The IMA group supports the link troubleshooting and automatic link recovery. recovery. In addition, the IMA group can automatically delete a link with excessive long delay. delay.



Fractional E1 IMA has the same functions as E1 IMA, and Fractional E1 CES has the same functions as CES.



For IMA negotiation of Fractional E1 IMA, only one or several 64 kbit/s timeslots in E1 on the NodeB side interconnect with the corresponding timeslots in E1 on the RTN side. Unlike common IMA, Fractional E1 IMA transmits valid timeslots, which requires less bandwidth.

Strategy

Physical layer clocks, IEEE 1588v2 clocks, and IEEE 1588 ACR clocks can be used to achieve frequency synchronization between NEs in order to meet BS frequency synchronization, microwave overhead clock synchronization, and retiming clock extraction requirements. IEEE 1588v2 clocks can achieve time synchronization between NEs and with BSs. CES ACR clocks can meet the frequency synchronization requirements of TDM services, and provide frequency synchronization for BSs.

Introduction to IEEE 1588 ACR IEEE 1588 ACR is a frequency synchronization technology. technology. To To be specific, the master equipment encapsulates the local system clock into a Sync pack et as a time stamp and transmits t ransmits the Sync packet to a packet switched network (PSN), which transparently transmits the Sync packet to the s lave equipment. On receiving the Sync packet, the slave equipment extracts the t ime stamp from the Sync packet and recovers the clock frequency by using the ACR algorithm. In this way, way, the clock frequency of the PTP equipment at the two t wo ends of a PSN is synchronized. IEEE 1588 ACR achieves only frequency synchronization and cannot achieve time s ynchronization.  As shown in the figure, to achieve frequency synchronization between area A and area C on the two sides of the PSN, enable the IEEE 1588 ACR function on the equipment on the two sides of the PSN. That is, the PTN 3900 sends Sync packets that are later transmitted through a PSN. On the RTN 950 enabled with the IEEE 1588 ACR function, the clocks are recovered and transmitted downstream through the physical layer.

Introduction to CES ACR CES ACR ACR is a function that uses the adaptive clock recovery (ACR) technology to recover clock synchronization information carried by CES packets. As shown in the figure, Master uses the E1 service clock/local clock c lock information as timestamps in RTP packet

headers and encapsulates them into CES packets. Slave recovers clocks according to the timestamps/SN in packets, therefore achieving frequency synchronization requirements of TDM services and BSs.

Introduction to IEEE 1588v2 IEEE 1588v2, defined by the IEEE, means the Precision Clock Synchronization Protocol for Networked Measurement and Control Systems (PTP for short). IEEE 1588v2 clock protocol is applied to precise time synchronization at each node on a distributed communication network. With the relevant hardware and software, the system clock of the network equipment (or client) synchronizes with the master clock on the network at the nanosecond level. Independently of the GPS signals, IEEE 1588v2 is a low cost time synchronization network solution.
