    Introduction

    A service is a globally unique entity that refers to a type of connectivity service for either Internet or VPN connectivity. Each service is uniquely identified by a service ID and an optional service within a service area. The 7210 SAS-Series service model uses logical service entities to construct a service. In the service model, logical service entities provide a uniform, service-centric configuration, management, and billing model for service provisioning.

    In the 7210 SAS-Series services can provide Layer 2/bridged service between a service access point (SAP) and another service access point (a SAP is where traffic enters and exits the service) on the same (local) router or another router (distributed). A distributed service spans more than one router.

    Distributed services use service distribution points (SDPs) to direct traffic to another 7210 SAS or SR router or other routers that supports MPLS, through a service tunnel. SDPs are created on each participating router, specifying the origination address (the router participating in the service communication) and the destination address of another router. SDPs are then bound to a specific customer service. Without the binding process, far-end router is not able to participate in the service (there is no service without associating an SDP with a service).

    Service Types

    The 7210 SAS-X, R6, R12 offers the following types of subscriber services which are described in more detail in the referenced chapters:

    Virtual Leased Line (VLL) services: Ethernet pipe (Epipe) A Layer 2 point-to-point VLL service for Ethernet frames.

    See Ethernet Pipe (Epipe) Services on page 132. Virtual Private LAN Service (VPLS) A Layer 2 multipoint-to-multipoint VPN. See

    Virtual Private LAN Service on page 267. Internet Enhanced Service (IES) A routed connectivity service used to provide IP

    services.This service is supported in 7210 SAS platforms operated in access-uplink mode for only inband management of the node (that is, it cannot be used as for configuring customer service in access-uplink mode). See Internet Enhanced Service on page 465.

    Virtual Private Routed Network (VPRN) A Layer 3 IP multipoint-to-multipoint VPN service as defined in RFC 2547bis. See Virtual Private Routed Network Service on page 751.

  • Service Policies

    Page 26 7210 SAS-X, R6, R12 OS Services Guide

    Service Policies

    Common to all 7210 SAS-Series connectivity services are policies that are assigned to the service. Policies are defined at a global level and then applied to a service on the router. Policies are used to define 7210 SAS-Series service enhancements. The types of policies that are common to all 7210 SAS-Series connectivity services are:

    SAP Quality of Service (QoS) policies which allow for different classes of traffic within a service at SAP ingress and SAP egress.QoS ingress and egress policies determine the QoS characteristics for a SAP. A QoS ingress policy applied to a SAP specifies the number of meters, meter characteristics (such as forwarding class, committed, and peak information rates, etc.) and the mapping of traffic to a forwarding class. A QoS egress policy defines the queue characteristics (such as CBS, CIR, PIR). A QoS policy must be created before it can be applied to a SAP. A single ingress and egress QoS policy can be associated with a SAP.

    Filter policies allow selective blocking of traffic matching criteria from ingressing or egressing a SAP. Filter policies, also referred to as access control lists (ACLs), control the traffic allowed in or out of a SAP based on MAC or IP match criteria. Associating a filter policy on a SAP is optional. Filter policies are identified by a unique filter policy ID. A filter policy must be created before it can be applied to a SAP. A single ingress and single egress filter policy can be associated with a SAP.

    7210 SAS-X allows the scheduling parameters (that is, priority and weight) to be specified per queue. They are no scheduling policies available for use.

    Accounting policies define how to count the traffic usage for a service for billing purposes.

    The routers provide a comprehensive set of service-related counters. Accounting data can be collected on a per-service, per-forwarding class basis, which enables network operators to accurately measure network usage and bill each customer for each individual service using any of a number of different billing models.

    Alcatel-Lucent Service Model

    In the Alcatel-Lucent service model, the service edge routers are deployed at the provider edge. Services are provisioned on the service routers and transported across an IP and/or IP/MPLS provider core network in encapsulation tunnels created using MPLS label switched paths (LSPs).

    The service model uses logical service entities to construct a service. The logical service entities are designed to provide a uniform, service-centric configuration, management, and billing model for service provisioning. Some benefits of this service-centric design include:

    Many services can be bound to a single customer. QoS policies, filter policies, and accounting policies are applied to each service instead of

    correlating parameters and statistics from ports to customers to services.

    Service provisioning uses logical entities to provision a service where additional properties can be configured for bandwidth provisioning, QoS, security filtering, accounting/billing to the appropriate entity.

    Service Entities

    The basic logical entities in the service model used to construct a service are:

    Customers (see page 29) Service Access Points (SAPs) (see page 29) Service Distribution Points (SDPs) (see page 35) (for distributed services only)

    Customers

    The terms customers and subscribers are used synonymously. The most basic required entity is the customer ID value which is assigned when the customer account is created. To provision a service, a customer ID must be associated with the service at the time of service creation.

    Service Access Points (SAPs)

    Each subscriber service type is configured with at least one service access point (SAP). A SAP identifies the customer interface point for a service on an Alcatel-Lucent 7210 SAS router (). The SAP configuration requires that slot, MDA, and port information be specified. The slot, MDA, and port parameters must be configured prior to provisioning a service (see the Cards, MDAs, and Ports sections of the 7210 SAS OS Interface Configuration Guide).

    A SAP is a local entity to the router and is uniquely identified by:

    The physical Ethernet port The encapsulation type The encapsulation identifier (ID)

    Depending on the encapsulation, a physical port can have more than one SAP associated with it. SAPs can only be created on ports designated as access in the physical port configuration.

    The Figure 3 shows a SAP used for customer service delivery with access-uplink SAPs (also known as, QinQ SAPs) used for service transport on 7210 SAS devices that support only L2 uplinks (also known as, access-uplink mode platforms).

    SAP Encapsulation Types and Identifiers

    The encapsulation type is an access property of a service Ethernet port. The appropriate encapsulation type for the port depends on the requirements to support multiple services on a single port on the associated SAP and the capabilities of the downstream equipment connected to the port. For example, a port can be tagged with IEEE 802.1Q (referred to as dot1q) encapsulation in which each individual tag can be identified with a service. A SAP is created on a given port by identifying the service with a specific encapsulation ID.

    Ethernet Encapsulations

    The following lists encapsulation service options on Ethernet ports:

    Null Supports a single service on the port. For example, where a single customer with a single service customer edge (CE) device is attached to the port. The encapsulation ID is always 0 (zero).

    Dot1q Supports multiple services for one customer or services for multiple customers (Figure 4).. The encapsulation ID used to distinguish an individual service is the VLAN ID in the IEEE 802.1Q header. For example, the port is connected to a Ethernet switch with multiple downstream customers.

    QinQ The QinQ encapsulation type adds a IEEE 802.1Q tag to the 802.1Q tagged packets entering the network to expand the VLAN space by tagging tagged packets,

    The following lists encapsulation service options on Ethernet access uplink ports:

    QinQ The QinQ encapsulation type adds a IEEE 802.1Q tag to the 802.1Q tagged packets entering the network to expand the VLAN space by tagging tagged packets, producing a double tagged frame. On the 7210 SAS-E, QinQ encapsulation is supported only on access uplink ports.

    Figure 4: Multiple SAPs on a Single Port

    The Figure 4 shows multiple SAPs used for customer service delivery on the same port and belonging to the same service, along with SDP used for service transport on 7210 SAS devices that support MPLS uplinks (also known as, network mode platforms). This is supported only in network mode.

NOTE: G.8032 control instance cannot use Default QinQ SAPs.cannot be enabled in the service with Default QinQ SAPs

    MVPLS with xSTP can be used for loop prevention. The Default QinQ SAPs inherit the state from the associated MVPLS instance.

    SAP Configuration Considerations

    When configuring a SAP, consider the following:

    A SAP is a local entity and only locally unique to a given device. The same SAP ID value can be used on another 7210 SAS-Series.

    There are no default SAPs configured on the node. All SAPs in subscriber services must be created.

    The default administrative state for a SAP at creation time is administratively enabled. When a SAP is deleted, all configuration parameters for the SAP will also be deleted. A SAP is owned by and associated with the service in which it is created in each router. A port with a dot1q encapsulation type means the traffic for the SAP is identified based on

    a specific IEEE 802.1Q VLAN ID value. The VLAN ID is stripped off at SAP ingress and the appropriate VLAN ID placed on at SAP egress. As a result, VLAN IDs only have local significance, so the VLAN IDs for the SAPs for a service need not be the same at each SAP.

    If a port is administratively shutdown, all SAPs on that port will be operationally out of service.

    QinQ access SAPs of type Q1.0 is not supported.

    QinQ SAP Configuration restrictions for 7210 SAS in Network mode only

    Listed below are the QinQ access SAP configuration guidelines for 7210 SAS in Network mode only.

    Processing of tagged packets received on SAPs configured in a service in which a QinQ SAP is also in use (not applicable when a QinQ SAP is not provisioned in a service).

    When a QinQ SAP is configured in a service, the number of VLAN tags in the packets received on NULL SAP, Dot1q SAP and QinQ SAP configured in the same service should match the number of VLAN tags implied by the port encapsulation mode. Packets that do not match are dropped by the hardware. That is, packets received with more than two VLAN tags on a QinQ SAP are dropped, packets received with more than one VLAN tag on a Dot1q SAP are dropped and packets received with tags (even packet with a priority tag) on a NULL SAP are dropped. Henceforth in this document, such packets are referred to as extra-tag packets.

    When a QinQ SAP is configured in a service, the number of VLAN tags in the packets received on the VC/pseudowire of type vc-vlan should be exactly one and packets received on the VC/pseudowire of type vc-ether should contain no tags (not even priority tag). If either case, packets that contain more number of VLAN tags than the number mentioned above are dropped. Henceforth the document refers to such packets as extra-tag packets.

    The system will provide a limited amount of counters to count the number of extra-tag packets dropped on SAP ingress. These counters are intended for diagnostic use.

    Table 3 displays the SAP types allowed in a service when QinQ SAP is in use:

    Table 3: SAP types in a service when QinQ SAP is in use (Network mode operation)

    0.* QinQ SAP configured in the service will accept only untagged or priority tagged packets, irrespective of whether a QinQ SAP is configured in the service or not.

    NOTE: 7210 supports a mechanism to transport QinQ packets in an Epipe with 2 or more tags, with some restrictions. For more information, see Ethernet Pipe (Epipe) Services on page 132.

    Service Distribution Points (SDPs)

    A service distribution point (SDP) acts as a logical way to direct traffic from one router to another through a uni-directional (one-way) service tunnel. The SDP terminates at the far-end device which directs packets to the correct service egress SAPs on that device. A distributed service consists of a configuration with at least one SAP on a local node, one SAP on a remote node, and an SDP binding the service to the service tunnel.

    An SDP has the following characteristics:

    An SDP is locally unique to a participating routers. The same SDP ID can appear on other 7210 SAS-Series routers.

    An SDP uses the system IP address to identify the far-end edge router. An SDP is not specific to any one service or any type of service. Once an SDP is created,

    services are bound to the SDP. An SDP can also have more than one service type associated with it.

    All services mapped to an SDP use the same transport encapsulation type defined for the SDP.

    An SDP is a management entity. Even though the SDP configuration and the services carried within are independent, they are related objects. Operations on the SDP affect all the services associated with the SDP. For example, the operational and administrative state of an SDP controls the state of services bound to the SDP.

    An SDP from the local device to a far-end router requires a return path SDP from the far-end 7210 SAS-Series back to the local router. Each device must have an SDP defined for every remote router to which it wants to provide service. SDPs must be created first, before a distributed service can be configured.

    SDP Binding

    To configure a distributed service from ALA-A to ALA-B, the SDP ID (1) must be specified in the service creation process in order to bind the service to the tunnel (the SDP). Otherwise, service traffic is not directed to a far-end point and the far-end device(s) cannot participate in the service (there is no service). To configure a distributed service from ALA-B to ALA-A, the SDP ID (5) must be specified.

    Spoke and MESH SDPs

    When an SDP is bound to a service, it is bound as either a spoke SDP or a mesh SDP. The type of SDP indicates how flooded traffic is transmitted.

    A spoke SDP is treated like the equivalent of a traditional bridge port where flooded traffic received on the spoke SDP is replicated on all other ports and not transmitted on the port it was received.

    All mesh SDPs bound to a service are logically treated like a single bridge port for flooded traffic where flooded traffic received on any mesh SDP on the service is replicated to other ports (spoke SDPs and SAPs) and not transmitted on any mesh SDPs.

    SDP Using BGP Route Tunnel

    SDP is enhanced to use BGP route tunnel to extend inter-AS support for L2 and L3 VPN services. An SDP can be configured to use MPLS transport method. MPLS SDP support is enhanced to allow a BGP route tunnel to reach the far-end PE. A single method of tunneling is allowed per SDP (for example, LDP, RSVP-TE LSP or BGP route tunnel). BGP route tunnel method is excluded if multi-mode transport is enabled for an SDP.

    A single method of tunneling is allowed per SDP (for example: LDP, RSVP-TE LSP or BGP route tunnel). BGP route tunnel method is excluded if multi-mode transport is enabled for an SDP.

    For inter-AS far-end PE, next-hop for BGP route tunnel must be one of the local ASBR. The LSP type selected to reach the local ASBR (BGP labeled route next-hop) must be configured under the BGP global context. LDP must be supported to provide transport LSP to reach the BGP route tunnel next-hop.

    Only BGP route labels can be used to transition from ASBR to the next-hop ASBR. The global BGP route tunnel transport configuration option must be entered to select an LSP to reach the PE node from ASBR node. On the last BGP segment, both BGP+LDP and LDP routes may be available to reach the far-end PE from the ASBR node. LDP LSP must be preferred due to higher protocol priority. This leads to just one label besides other labels in stack to identify VC/VPN at far-end PE nodes.

    SDP Keepalives

    SDP keepalives actively monitor the SDP operational state using periodic Alcatel-Lucent SDP ping echo request and echo reply messages. Alcatel-Lucent SDP ping is a part of Alcatel-Lucents

  • Service Distribution Points (SDPs)

    Page 38 7210 SAS-X, R6, R12 OS Services Guide

    suite of service diagnostics built on an Alcatel-Lucent service-level OA&M protocol. When SDP ping is used in the SDP keepalive application, the SDP echo request and echo reply messages are a mechanism for exchanging far-end SDP status.

    Configuring SDP keepalives on a given SDP is optional. SDP keepalives for a particular SDP have the following configurable parameters:

    Admin up/admin down state Hello time Message length Max drop count Hold down time

    SDP keepalive echo request messages are only sent when the SDP is completely configured and administratively up and SDP keepalives is administratively up. If the SDP is administratively down, keepalives for the SDP are disabled.

    SDP keepalive echo request messages are sent out periodically based on the configured Hello Time. An optional message length for the echo request can be configured. If max drop count echo request messages do not receive an echo reply, the SDP will immediately be brought operationally down.

    If a keepalive response is received that indicates an error condition, the SDP will immediately be brought operationally down.

    Once a response is received that indicates the error has cleared and the hold down time interval has expired, the SDP will be eligible to be put into the operationally up state. If no other condition prevents the operational change, the SDP will enter the operational state.

    For information about configuring keepalive parameters, refer to Configuring an SDP on page 67.

    SDP Administrative Groups

    This feature introduces the support of SDP administrative groups, referred to as SDP admin groups. SDP admin groups provide a way for services using a PW template to automatically include or exclude specific provisioned SDPs. SDPs sharing a specific characteristic or attribute can be made members of the same admin group.

    The user first creates the admin groups that are to be used by SDPs on this node:

    config>service>sdp-group>group-name group-name value group-value create

  • Services

    7210 SAS-X, R6, R12 OS Services Guide Page 39

    A maximum of 32 admin groups can be created. The no option is only allowed if the group-name is not referenced in a pw-template or SDP.

    The group value ranges from zero (0) to 31. It is uniquely associated with the group name at creation time. If the user attempts to configure another group nam
