What is SAP in Nokia?

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 router (Figure 6). The SAP configuration requires that slot, XMA/MDA, and port/channel information be specified.

What is Nokia SDP?

The Nokia service model uses encapsulation tunnels (also referred to as service tunnels) through the core to interconnect 7705 SAR and SR routers. An SDP is a logical way of referencing the entrance to an encapsulation tunnel.

What is Nokia VPLS?

Virtual Private LAN Service (VPLS) as described in RFC 4905, Encapsulation methods for transport of layer 2 frames over MPLS, is a class of virtual private network service that allows the connection of multiple sites in a single bridged domain over a provider-managed IP/MPLS network.

What is a VPLS circuit?

Virtual private LAN service (VPLS) is an Ethernet-based point-to-multipoint Layer 2 VPN. It allows you to connect geographically dispersed Ethernet LAN sites to each other across an MPLS backbone.

What is SAP in computer networking?

A Service Access Point (SAP) is an identifying label for network endpoints used in Open Systems Interconnection (OSI) networking. The SAP is a conceptual location at which one OSI layer can request the services of another OSI layer.

What is a pseudowire Ethernet?

In computer networking and telecommunications, a pseudowire (or pseudo-wire) is an emulation of a point-to-point connection over a packet-switched network (PSN). The pseudowire emulates the operation of a “transparent wire” carrying the service, but it is realized that this emulation will rarely be perfect.

Why is SAP used?

What is SAP Used For? As one of the world’s leading software systems dedicated toward the management of business processes, SAP facilitates effective data processing and information flow across organizations. SAP connects all parts of a business into an intelligent suite on a fully digital platform.

Why is MPLS needed?

The benefits of MPLS are scalability, performance, better bandwidth utilization, reduced network congestion and a better end-user experience. MPLS itself does not provide encryption, but it is a virtual private network and, as such, is partitioned off from the public Internet.

What is L2VPN pseudowire?

L2VPN Pseudowire Switching allows the user to extend L2VPN Pseudowires across an inter-AS boundary. This feature connects multiple contiguous pseudowires to form an end-to-end multihop pseudowire. Network topology: One Pseudowire VC ID 1000 is established within MPLS-A network between PE1 and PE-AGG1 routers.

What are the QoS characteristics of a sap?

QoS ingress and egress policies determine the QoS characteristics for a SAP. A QoS policy applied to a SAP specifies the number of queues, queue characteristics (such as forwarding class, committed, and peak information rates, etc.) and the mapping of traffic to a forwarding class. A QoS policy must be created before it can be applied to a SAP.

What kind of SAP does a VPLS use?

VPLS uses a native Ethernet SAP or a bridged PDU encapsulated SAP on the customer-facing (access) side, which simplifies the LAN/WAN boundary and allows for rapid and flexible service provisioning. VPLS offers a balance between point-to-point pseudowire service (Epipe, Ipipe, etc.) and outsourced routed services (VPRN).

Can a spoke SDP be copied to a sap?

This extension is referred to as a split horizon group or residential bridging. Traffic arriving on a SAP or a spoke SDP within a split horizon group is not copied to other SAPs and spoke SDPs in the same split horizon group; however, it is copied to SAPs and spoke SDPs in other split horizon groups, if these exist within the same VPLS.

Which is the default mode of operation in SAP?

Normal or service queuing is the default mode of operation for SAP ingress queuing. Service queuing preserves ingress forwarding bandwidth by allowing a service queue defined in an ingress SAP QoS policy to be represented by a group of hardware queues.
