The Manager Control is a PKT application local state of the port:
When “Enabled” the port is under the control of the Ethernet Service Traffic Management, that can use it as Ethernet segment extremity. Its usage state is NotMeaningful in the Construction domain, but is managed in a significant way by Ethernet traffic management.
The state of this attribute is automatically set to “Enabled” when the port is assigned to a Domain.
When “Disabled” the port is fully controlled by Construction domain that can use it as Extremity of an internal Link over Cable (Ethernet or MPLS or T-MPLS as Supported Layer). Its usage state is managed in the Constructor domain.
“Disabled” is the default attribute when the NE or the ENE is created.

The External Network Element management allows to define inside PKT, NEs or Networks or Customer Edges in order to allow the operator to have a complete network view. In a topology, some ENEs can be added to represent a NE or a set of NEs, which are internal to the managed network but not directly administrated by the PKT: this is the role of the Inner Equipment, connected through NNI interfaces. An ENE can be used to represent Customer Edge Device; this object is included only in order to improve the USM representation: this is the role of the Customer Edge, connected through UNI interfaces. An ENE can be added to represent different Operator Networks: this is the role of the PVLAN Network, connected through IWI Interfaces. The Inner and the PVLAN External Network Elements can be used as Edge Node of the Ethernet Service, while a Customer External Network Element is always outside of the Ethernet Service management.

3 Link Aggregation (LAG) management
Introduction
Link Aggregation is a method for aggregating N parallel instances of full duplex point-to-point links, operating at the same data rate (FE, GBE, 10GBE), into a single logical link. Specifically, a Link Aggregation Group is defined, such that a MAC client can treat this group as it were a single link. (max N=16) Aggregation Link

3 Link Aggregation (LAG) management
LAG main target
The main goals of Link Aggregation are: Increased Link Capacity: the performance is improved because the capacity of an aggregated link is higher than that one provided by a single physical link. High Link Availability: the loss of a link within an aggregation group reduces the available capacity but the connection is maintained and the data flow is not interrupted. Statistical distribution of frames across the links (relying on hashing key)

3 Link Aggregation (LAG) management
Link Aggregation Control Protocol (LACP)
Link Aggregation management in the network is based upon the communication, between the aggregate partner equipments, of LACP messages (Link Aggregation Control Protocol). The LACP packets transport information about set-up, aggregation capability, links failures, automatic reconfiguration after failure, etc. The Link Aggregation control messaging is managed by means of special control frames LACPDU (Link Aggregation Control Protocol Data Unit), periodically sent, in band, by the nodes using the Link Aggregation function.

3 Link Aggregation (LAG) management
Frame distribution (Hash Key)
All the packets belonging to the same conversation are transported over the same link. More conversations can be transported on the same link. A fair load-balancing is not guaranteed, since conversations and packets can not be fragmented. The packets distribution over the constituting links is based upon classification of the following masks: 1. 2. 3. 4. 5.
+ MPLS Labels + MPLS Labels + + MPLS Labels + ] + + MPLS Labels + ] + +

Graphical Interfaces Network Topology 1350OMS 1350OMS-PKT R 9.1.1 Operation
A priority value is associated to each port of the bundle; lower values mean higher priority.
A port of the group is classified, by the system, in “Active” or “Stand-by” state, depending from the port-priority values and from the LAG-size. E.g.: if port-rate=1Gb/s, LAG-size=5, number of ports=7, then 2 ports (those ones having lower priorities) are classified as “stand-by” by the system.
In case of a protected traffic, if a link failure occurs, the traffic of the failed link will be switched to the stand-by port having a priority value just lower than the failed one.
If the traffic is not protected, i.e. no stand-by ports are configured, then the traffic of the failed link will be redistributed to all ports, if bandwidth is available. In this case frames discarding may occur.

LAG size: is the number of physical Ports that belong to the LAG Port. It is possible to add a number of ports different from the LAG size:
If number of ports is less than the lag size: the LAG is in a degraded state.
If number of ports is greater than the lag size: the exceeding ports are in a stand-by status. They provide protection to the working ports according to port priority.
Client Type: ETS or ETB LACP: can be set at creation only Hash Key: frame distribution can be modified even when LAG is active Port Priority: priority is used to select active/stand-by physical ports.

The three main concepts are:
Ethernet Services:
An Ethernet service connect two or more PEs, each associated to a CE
It belongs to a given Customer; it is composed of one or more Ethernet Virtual Connections
Ethernet Virtual Connections:
The Ethernet services are implemented directly over SDH or SONET network layer (GFP or LAPS) or over an intermediate MPLS or T_MPLS network layer or over an intermediate RPR like ring or directly over a cable. An Ethernet service can use every type of combination of these network support layers. An Ethernet Virtual Connection (EVC) is an Ethernet end to end connection having a specified topology (point to point, point to multi-point and multi-point to multi-point) and a packet forwarding rules (unicast, multicast, broadcast). One or more Ethernet Virtual Connection (EVC) form an Ethernet service. Each unidirectional end to end connection belonging to an EVC is called Ethernet Segment: a point to point EVC is formed by two unidirectional Ethernet segments. This is the elementary connection managed by 1354 BM Ethernet.
Ethernet segments:
An Ethernet segment has associated a “quality of service” value (Guaranteed, Best Effort, Regulated), the bandwidth and the forwarding rules based on VLAN management.

A VLAN consists of a single broadcast domain and solves the scalability problems of large flat networks by breaking a single broadcast domain into several smaller domains or VLANs. LAN switches can be used to segment networks into logically defined virtual workgroups. This logical segmentation is commonly referred as VLAN communication. Switches can be used as the core device that controls individual VLANs. Routers can provide inter VLAN communication and / or VLAN access to shared resources such as servers and hosts.

Differentiated Service _ Reminder
The Differentiated Service is a coarse-grained, Class-based mechanism for traffic management. It operates on the principle of traffic classification, where each data packet is placed into a limited number of traffic classes; each router of the network is configured to differentiate traffic based on its class. Each traffic can be managed differently, ensuring preferential treatment for higher-priority traffic on the network

DSCP_Reminder
DSCP (Differentiated Service Code Point) is a field inside the IPv4 packet, that specifies a particular per-hop behaviour (PHB) applied to the packet Different Class of Service are assigned to the traffic: routers at the edge of the network classify packets and mark them with DSCP value in a DiffServ network. This in order to provide the appropriate QoS treatment. DSCP is mapped in the six most significant bit of the DiffServ field 0

IP DSCP management
IP routers, in charge of managing the frontier between IP and Ethernet, should translate the IP Diff-Service Code point (DSCP) field into Ethernet priority bits. However, since some routers don’t perform that kind of translation, the NE functionalities have been extended to IP DSCP management

Therefore, an operator managing an Ethernet network may offer differentiated services also when IP routers are not able to write the PRI bits of the transmitted Ethernet frames. In fact, the NE inspects the code-point of the IPv4 header, representing PHB and pushes at the NNI a VLAN tag whose PRI bits value encodes that PHB information.

Traffic Classifier: It works as filter matching the incoming frame types to be transported up to the far end through the SDH network. Policy Control
The policy control is an application to configure the edge nodes with QoS parameters, IEEE 802.1p, or as alternative, DSCP classification (by port).
At the edge of the network, frames (identified by port/VLAN/EtherType) are classified in a set of priority levels and tagged according to classification criteria. In the core of the network, frames are switched using different queues, based on their priority tag.
The Ethernet priority bits or the IP DSCP are used together with the VLAN id (forming just single values) to individuate an Ethernet traffic flow. A traffic type (Guaranteed, Regulated or Best Effort) and a bandwidth are associated to this flow is. When ISA PR EA or ISA ES16 or 4G NE is the edge node, these information (traffic type and bandwidth) will be mapped on PIR/CIR (and CBS / PBS), then classified in term of priority (green, yellow or red frames) and then mapped on MPLS layer or on SDH VC. In case of ISA E/FE/GE board (Q3 board) these bits are transparently transported.
The ingressing Ethernet frames can be managed by a policy “colour blind” (the incoming classification is not used) or “colour aware” where the priority bits or the IP DSCP are taken into account by the NE.
N.B: the NE manages the IPv4 DSCP translation only at UNI/IWI interface, while at NNI handle only the classification based on PRI bits

The Ethernet Edge physical ports represent the border of the network managed by the 1350OMS-PKT. They are the extremities of Ethernet services, EVCs and Ethernet segments. An Ethernet Edge Physical port is the image, on the Ethernet Domain, of either an Ethernet Physical Port or an External Termination Port of the Construction Domain It cannot be explicitly created or deleted by the operator: it is automatically created when a proper PPT (ETH Physical Port) or ETP (External Termination Point) is assigned to the Domain and it is automatically deleted when it is de-assigned. Whenever a new edge physical port is created, it comes with an Activation State “down” and will be Up when the service to which the edge port belongs is implemented. If the edge port is ETP, then is created with Activation State Up and the VLAN Type is the default one (I.e. 8100).

Color Profile definition _ Reminder
A color profile allows the operator to define a priority in accepting or rejecting incoming frames at the network boundary ( “INFLOW” of ES unit). A color profile is a customized table making a relation between “Customer priority” and the Priority queue in the switch. Example:

After its creation, a color profile has to be associated to a “Color aware” Ethernet segment to be taken into account. Moreover, a traffic classifier and a traffic descriptor will have also to be associated to this Ethernet segment. A given color profile will be downloaded as an ES unit configuration during the related Ethernet segment implementation.

According to the traffic contract, to the policing mode, and to the available bandwidth, the priority of a data flow into the Provider network is assigned by the traffic scheduler of the system. Considering an ES unit as an Ethernet switch, 3 queues, corresponding to green, yellow and red will be managed for a given port.

For a given “INFLOW”, the coloring of the “Provider VLAN” is managed as follow:
The scheduler of an Ethernet data flow can be indicated on the 3 “user priority” bits (802.1p) of the “Tagged Ethernet” frame or on the 6 “DSCP” bits of the IP packet.
A “Color Profile mode” has been introduced in order to define if the Color Profile has been built in order to manage color for NOT IP packets or for IP Packets.
The provider traffic can be “coloured” if the S-VLAN mode is enable :
“green” for frames to be passed in any case;
“yellow” for frames to be passed if the band is available;
“red”
for frames to be discarded.
(1) “Unbound” means that “NoProfile” is associated to the “ColorProfile” field; “Bound” means that a Color Profile has been assigned. (2): in cases different from “Color Aware”, the colouring is performed by the scheduler, depending on the traffic condition. (3): in this case the “Priority” value of the Classifier associated to this InFlow must be different from “untagged” or “don’t care”.

Committed Information Rate The CIR is the minimum guaranteed rate that the network will deliver for an Ethernet Transport Service (ETS) flow under normal operating conditions. Peak Burst Size It specifies the maximum amount of buffering allocated for an Ethernet Transport Service (ETS) flow. The incoming traffic offered over the PIR is buffered up to the specified PBS. Once all buffers are depleted, all excess traffic is typically dropped. PBS buffers are allocated to absorb the burst when the traffic is continuously received at the line rate. Committed Burst Size The CBS is associated with the CIR and specifies the amount of buffering allocated for Ethernet packets to be en-queued when the Ethernet Transport Service (ETS) flow is continuously received.

The Ethernet services are based on EVC: the service is like a container of one or more EVCs, a specific type of service introduces some restriction on the EVC types to be used for that service.
An EVC is composed of a set of unidirectional point to point connections called « Ethernet segment ».
1350OMS PKT subsystem manages three types of EVC:
Point to Point

The Allocation consists in finding a route between the end physical ports of the Ethernet segment. To be able to allocate an Ethernet segment: - the Ethernet segment Provisioning state must be Defined - a list of constraint containing all transport links used is associated to the Ethernet segment - traffic profile, traffic descriptor and traffic classifier must be associated to the Ethernet segment. The 1350OMS PKT check the “validation” of the transport links to be used in term of traffic type, bandwidth and continuity of the chosen transport links.

Bridge Traffic management
Bridge traffic management deals with set-up of data traffic toward the customer edge, STP tuning and VLAN distribution inside and at the edge of the domain. One function of bridge traffic management is the EVC association to bridge infrastructure and EVC Termination addition: A set of edge ports, assigned to a bridge domain, are included in the EVC. EVC association to domain is automatic when the edge ports are specified at EVC creation-time and when the Transport Link are assigned to the same domain: the terminations of one EVC correspond to edge ports belonging to the same bridge domain. In case of Virtual or Provider domain, one EVC is optionally characterized by one VLAN bundle, I.e. a group of VLAN

In case of Provider Bridge termination, one Traffic descriptor, one Color Profile and many Traffic Classifiers may be optionally associated to each EVC Termination. The S-VLAN (pre-IEEE 802.1ad) allows the service provider to stack another VLAN tag on the frames coming on the UNI such that traffic from different customers is put on different S-VID and thus segregated.

4 Connection-less Ethernet Virtual Connection
Definitions
Connection-Less EVC specifies the connectivity between a set of edge ports (EVC Termination) in a specified Bridge Domain
MAC Bridge: in this case there exist only one EVC for the Domain VIRTUAL / PROVIDER Bridge: many EVC may insist on the same Domain
EVC Termination: it is conceptually associated to:
One Ethernet interface (either local or remote) in case of MAC Bridge One set of ETB virtual port insisting on the same Ethernet interface in case of Virtual Bridge: it is the set of ETB virtual ports corresponding to the C-VLAN of the EVC (there is one ETB virtual port for each C-VLAN) One ETS_P flow or set of ETS_P flow in case of Provider Bridge: it is the flow or set of flow referenced by the Traffic Classifier associated with the C-VLAN of the EVC

The operation consists in comparing the content of the NE MIB with the content of the PKT database; after the comparison the differences are classified as follow: Data existing in the NE and missing in the PKT Data existing in the PKT and missing in the NE Different data using the same resources in NE and PKT
On the basis of the audit file information the operator may proceed with one of the following operation: Reserve, in order to insert in the PKT the resources discovered in the NE MIB not present in the PKT database (not available in current release)
Align, in order to insert in the NE MIB the resources discovered in the PKT not present in the NE Force Align, in order to full re-align NE MIB to the PKT database 378

Measures are defined on 1350OMS-ETH transport entities (EVC, Tunnel, PseudoWire) and requested on NE’s Termination Points (TPs).
For each transport entity a PM transport is created. For each TP a PM TP is created.
1350OMS-ETH requests 1350OMS-EML to start the counters on NEs whose TPs have to be monitored.

Measure:
Activated: TP counters are started, hence PM results and PM alarms can be inspected.
Stopped: TP counters are stopped. Only former PM results can be inspected.
Standby: the monitoring activities are interrupted temporarily because the PM Transport is deimplemented. Terminated: the monitoring activities are interrupted forever because the PM Transport has been removed. This state can be seen because the Measure’s attribute “Auto Purge” is set to “False”.

Granularity: is the monitoring frequency, i.e. the frequency of historical data counters grouping. The operator can select: - 24 hours . Data are grouped per day. – 15 minutes. Data are grouped per quarter of hour. Involved TPs: choose the TPs involved in the measurement ( No Points, only End Points, only Intermediate Points, All Points) CSV Reporting: define the periodicity of the CSV file creation as report: 2 Hours or 24 Hours in case of 15 min granularity; 24 Hours in case of 1 day granularity Policy: which deals on maintaining PM data: - Keep: data are maintained - Purge on stop: data are purged at the measure termination - Purge on delete: data are purged at the measure deletion - Not meaningful

Destination Type:
files: a single report file is created at the chosen frequency (window) for all the measures correlated to the report. For example, by correlating 4 different 15min measures to a report having a window of 1 hour, only 24 files are created in a day: i.e. every hour a single file is created with the results of all the measures. The file’s name is: _Report’s User Label_window_x_N00000.csv (_My_Report_15MIN_8_N00000.csv). file: a report file is produced at the chosen frequency (window) for each measure correlated to the report. For example, by correlating 4 different 15min measures to a report having a window of 1 hour, 24x4 = 96 files are created in a day: i.e. every hour a file is created for each measure. The file’s name is: _Transport’s User Label_window_x_co.csv (_MyPath_auto_0_15MIN_8_co.csv).
Window: it must be suitable for the granularity:
granularity = 15min window = 15min, 1h, 2h, 24h.
granularity = 24h window = 24h, 1week, 1month, 2months, 1year.
