ACM Adaptive Code Modulation SIAE MICROELETTRONICA implements MSE based Adaptive Code and Modulation in all channel bandwidths. 10 ACM profiles are available for automatic changes in accordance with the link condition and selected parameters (highest modulation , lowest modulation , masks , power mode etc,etc). ACM togheter with QoS fits perfectly with modern networks requirements in order to ensure the high priority traffic to be never dropped even in the worst link conditions. ACM is obviously hitless in order to avoid any kind of retransmissions for TCP/IP session or ,sleep/ syncloss, in case of TDM native transport (not applicable for ALFOplus).

ACM includes all the possible modulation schemes (4QAM to 1024QAM) and provides 3 additional different profiles (with different FEC rate coded for existing modulation schemes called 256QAMs - 16QAMs - 4QAMs). Those new additional ACM profiles maximize throughput, system gain and link availability while maintaining same constellation type just changing on-fly the ratio between payload bits and protection bits in the FEC corrector . This unique set of profiles allows achieve –at the same time– higher capacity in good propagation conditions and really higher strength with tough conditions. ACM is available in all the protected configurations (HSBY/SD/FD and XPIC).

Note that ACM works independently for uplink and downlink and it is able to protect against fading up to 100db per second.

Figure 1 - ALFOplus ACM profiles

Traffic classification The adaptive modulation entails a change in the available bandwidth with regard to the modulation scheme that is used and as a consequence, moving from higher modulation downward, the decreasing of the traffic capacity. The possibility to classify the traffic allows to decide what traffic to transport according to the available

bandwidth. For example if the modulation is reduced from 128QAM to 4QAM all traffic exceeding 4QAM capacity cannot be carried anymore.

SIAE MICROELETTRONICA solutions have eight traffic switch queues –through which all possible priority classes can be managed– with user configurable quality management.

SIAE MICROELETTRONICA implementation manages ETH traffic as follows:

• ETH packets are usually classified according to 802.1p Layer2 tag; SIAE MICROELETTRONICA systems are also able to classify them, according to IPv4 TOS or IPv6 TC and to MPLS “Exp bits”.

This allows real time and high priority traffic to be always transmitted.

Link Quality measurement In order to trigger a modulation change some switching criteria must be implemented. SIAE MICROELETTRONICA solutions are based on MSE measurements that allow the system a fastest react to any source of degradation, even before FEC detecting/correcting errors.

Throughput Throughput is defined according to paragraph 26.1 of RFC2544.

Throughput depends on configuration and capacity; in the following table different throughput values will be specified for each configuration.

Ethernet Resiliency LLF - Link Loss Forwarding

PIRL - Peak Input Rate Limiting - In order to control the traffic flows incoming the equipment and thus the network, this access limitation/control policies is introduced with a “leaky bucket architecture”

RSTP - Rapid Spanning Tree Protocol - is a link layer network protocol that ensures a loop-free topology for any bridged LAN. Thus, the basic function of STP is to prevent bridge loops and ensuing broadcast radiation.

ELP - Ethernet Link Protection - ELP is used to protect the network from Ethernet link failures in various network topologies and application LAG - Link Aggregation – is a recommendation (802.1ax-2008 or 802.3ad) designed for using multiple media in parallel to increase the link speed beyond the limits of any one single medium and increase the redundancy for higher availability

ERP - Ethernet Ring Protection is a ITU-T under G.8032 Recommendation and provide sub-50ms protection and recovery switching for Ethernet traffic in a ring topology and at the same time ensuring that there are no loops formed at the Ethernet layer. G.8032v1 supported a single ring topology and G.8032v2 supports multiple rings/ladder topology.

QoS management QoS refers to the ability of a network device to provide improved services to selected network traffic over various underlying technologies, including Ethernet and wireless LANs. In particular, QoS feature provides an improved and more predictable network services, as follows:

• Improving loss characteristics

• Avoiding and managing network congestion ALFOplus Series – High Capacity IP Full Outdoor Document Number

QoS is implemented in SIAE MICROELETTRONICA products in a multilevel approach:

• VLAN per port

• Layer2 VLAN identifiers (802.1Q)

• Layer2 priority bits (802.1P QoS) • Layer3 priorities IPv4 (ToS or DSCP) or IPv6 (TC)

• Frame prioritization based on MPLS “EXP bits”

Layer2 priorities Priority queues are introduced on switches output ports. 802.1p describes 8 priority levels, mapped onto 8 output queues.

A typical mapping scheme is shown below.

Two scheduling algorithms are available in SIAE MICROELETTRONICA equipment: strict priority or weighted scheduling WFQ (SW selectable).

• Strict Priority means that Higher priority queues are emptied first

• Weighted scheduling (WFQ) means that queues are served proportionally to their configurable weights (from 1 to 100)

• Mixed Strict Priority and WFQ

SYNCRONIZATIONS

Modern telecommunication networks need to be efficiently synchronized before to be ready to transport payload traffic.

Two targets can be aim in order to archive synchronization :Frequency Lock and/or Phase lock

Frequency Lock and Phase lock are applicable respectively to GSM/UMTS-FDD networks (50ppb accuracy) and CDMA/UMTS-TDD (sub 20 ppb accuracy and max 3milli secs phase discrepancy)

Upto now a TDM circuit was always present in the network so that synchronization distribution was always carried by a E1 or a STM1 chain from CORE to BTS/NODEB according with performance requested.

A flat,all IP LTE network (in FDD or TDD flavor doesn’t metter) requires a new approach in order to archive time/freq distribution. In that kind of “ all packet scenario” Synchronous Ethernet and PTP(typically 1588v2) protocols became to be key solutions.

SYNCHRONOUS ETHERNET

Synchronous Ethernet or SynceE delivers clocks directly on physical layers according to standardized ITU G.8261. This method implements a synchronization based on TDM paradigm (even applied to a Ethernet port) and it offers a synchronization quality comparable with a E1 synchronization in a GSM/UMTS network. SyncE can accumulate jitter, but it could be compensating using accurate SSU filtering. Note that all the network elements must comply with ITU G.8261 at least for a single port in order to propagate the timing on the physical layer in a chain topology.

PTP Precision Time Protocol

PTP is a message based protocol able to distributes accurate time and frequency over packet based network: synchronization is achieved using a series of messages transactions between master(s) and slaves elements.

PTP performs functions as measures path delay and switch residence time then distributes time informations.

Basically time tagged packets are generated by a master source reference(GPS or Controlled oscillator based device) and received by slave nodes to be synchronize (ex ENodeB);.

To be noted that phase synchronization is sensitive to the network behavior and the accuracy depends on the clock recovery algorithm, PDV (Packet Delay Variation) and congestions condition.

ALFOplus synchronization Methods

ALFOplus supports Synchronous Ethernet in both electrical and optical ports for Frequency distribution. Additionally, in order to comply with requirements of LTE networks, implements a dedicated high priority path able to accept and forward 1588v2 packet s efficiently . This path is optimized and strictly controlled in terms of absolute delay and delay variation (PDV) as requested by the demanding PTP protocol.

1588 v2packets can be switched in that controlled and optimized path by automatic packet recognition OR according to VLAN ID assignments.

A typical mapping queues scheme is modify as shown below adding a new queue to manage those packets

IEEE 802.1Q VLANs Virtual LAN (VLAN) support is the ability to logically break a LAN into a few smaller LANs and prevent data from flowing between the sub-LANs.

VLANs can be activated in three different ways:

• Based on Port. A packet belongs to a particular VLAN, depending on the local port ID. This means that each packet received on a specific port will be forwarded only to the ports belonging to the same VLAN.

• Based on IEEE 802.1Q TAG. A packet belongs to a particular VLAN, depending on its VLAN ID, defined by the VID (VLAN Identifier) TAG content.

• Hybrid. It is a mix of previous ones. Locally configured tagged frames are managed according IEEE 802.1Q TAG, all others follow port rules.

SIAE MICROELETTRONICA equipment can also be configured to add a VLAN tag (VD and user priority) to untagged traffic. SIAE MICROELETTRONICA products support VLAN stacking (QinQ). This means that if input traffic is 802.1Q compliant – i.e. VLANs are implemented – it is possible to create other VLAN inserting 4 additional bytes in Ethernet header for traffic switching and QoS purposes.

VLAN stacking (also named QinQ) is a feature that allows an Ethernet frame to include more than one IEEE 802.1Q TAG. The scope of VLAN staking is to differentiate the traffic at different levels when the packets must cross networks managed by different entities.

SIAE MICROELETTRONICA radio systems supports the VLAN stacking. Once a packet comes into the radio, it is possible to add a new IEEE 802.1Q TAG with an ID depending from the port, from VLAN or type of service. Of course, at egress side it is possible to remove such additional VLAN tag, making transport totally transparent.

Header compression SIAE MICROELETTRONICA has developed a two level header compressor that is able to hash L2, L2.5, L3 and L4 header’s protocols and thus massively increase the available radio throughput. The packet compression gain provided is from 3% up to 200% , depending on payload, protocols stacks and packet size.

In the following figure, supported Header Compression protocol and various compression rates are reported, in relation with packet sizes compressed protocol stacks.
