Resource Type Resource Package Description
Channel Channel equipment A channel is a logical communications representation that is multiplexed over a physical connection, for example, SONET or TDM channel. The Alcatel-Lucent 5620 SAM Technology Pack currently supports only channels that are running the Point-to-Point Protocol (PPP).
Hardware environment Hardware environment equipment Hardware environment represents a card in a router, and has temperature information about that card.
Link Aggregation Groups (LAGs) LAG Interface lag Link Aggregation Group (LAG) services operate in a network that the Alcatel-Lucent 5620 SAM manages.

The system administrator uses the Alcatel-Lucent 5620 SAM-O to manage the following tasks:

  • Configure LAGs to increase the bandwidth available between two network devices, for example between two Alcatel-Lucent routers
  • Configure the LACP to maintain link configuration information
MPLS Service MPLS Service mpls Engineering Task Force (IETF) initiative that integrates Layer 2 information about network links (bandwidth, latency, utilization) into Layer 3, within a particular autonomous system or Internet Service Provider (ISP), to simplify and improve Internet Protocol (IP) packet exchange. VPLS uses IP/MPLS technology to deliver a highly scalable, any-to-any connectivity. MPLS provides network operators with a great deal of flexibility to divert and route traffic around link failures, congestion, and bottlenecks.

When packets enter an MPLS-based network, Label Edge Routers (LERs) give the packets a label as an identifier. These labels contain information based on the routing table entry: destination, bandwidth, delay, and other metrics. The labels also refer to the IP header field (source IP address), Layer 4 socket number information, and differentiated service. When this classification is complete and mapped, different packets are assigned to corresponding Labeled Switch Paths (LSPs), where Label Switch Routers (LSRs) place outgoing labels on the packets. With these LSPs, network operators can divert and route traffic based on data-stream type and Internet-access customer. The system administrator uses the Alcatel-Lucent 5620 SAM-O to manage the following tasks:

  • Configuration of Multiprotocol Label Switching (MPLS) paths and Labeled Switch Paths (LSPs) on managed routers
  • Provisioning of MPLS paths and LSPs on managed and unmanaged routers
Network Network Queue nqueue Network queues are the queues that feed the network-facing interfaces of the nodes in a network. Network-facing interfaces are internal interfaces within a network, and are not accessed by users.
OAM Test OAM Test * icmp
  • mpls
  • service
  • svt
  • ethernetoam
Object Access Method (OAM) ping tests measure network traffic characteristics at different levels of the network stack.

The Alcatel-Lucent 5620 SAM Technology Pack currently supports ping tests for Internet Control Message Protocol (ICMP), LSPs, sites, tunnels, and Virtual Circuit Connection Verification (VCCV) [custom: Ethernet 802.1ag CFM (ethernetoam)].

Physical Port Physical Port equipment A physical port is a hardware item in the Alcatel-Lucent 5620 SAM environment. Physical ports connect to other devices in the network and have an associated port identifier. The Alcatel-Lucent 5620 SAM defines an equipment.PhysicalPort class for each physical port or interface in the network.
PPP Control Protocol PPP Control Protocol ppp PPP control protocol consists of messages that control the PPP connection, or provide status information for the connection. PPP control protocol data is in contest to the actual PPP packet data. The PPP control protocol establishes and maintains the PPP connection.
PPP Interface PPP Interface ppp PPP interfaces use the Point-to-Point Protocol (PPP) to create a direct connection between two nodes in a network. With PPP, you can authenticate the connection, encrypt the transmitted data to ensure privacy, compress the transmitted data, and detect any errors during the transmission.
SAP Access Interface service Access Interfaces, also known as Service Access Points (SAPs), are the points at which customers who use Alcatel-Lucent 5620 SAM services can access the network. Access Interfaces are logical entities. These interfaces are relevant to Layer 2 services such as VPLS, and to Layer 3 services such as VPRN.

The Alcatel-Lucent service-aware routers use queues on a per-SAP basis to manage and prioritize the service traffic. Traffic might be assigned to a particular queue based on QoS classification levels, and one queue might handle one or multiple levels of traffic. The Alcatel-Lucent 5620 SAM Technology Pack supports Egress Service Queues (also known as SAP egress queues) and Ingress Service Queues (also known as SAP ingress queues).

SAP Egress Service Queue * aengr
  • service
Egress Service Queues must have the following elements:
  • A unique access egress policy ID
  • At least one defined default queue

Egress Service Queues can also have the following elements:

  • Up to eight separate, additional queues for each of the eight supported forwarding classes
  • IEEE 802.1p priority value remarking based on forwarding class

Each queue in a policy is associated with one or more of the supported forwarding classes. Each queue can have its own queue parameters that enable individual rate shaping of the forwarding classes mapped to the queue. Various Alcatel-Lucent routers also support more complex service queuing model configurations.

SAP Ingress Service Queue * aingr
  • service
Ingress Service Queues must have the following elements:
  • A unique access ingress policy ID
  • At least one default unicast forwarding class queue
  • At least one multipoint forwarding class queue

Ingress Service Queues can also have the following elements:

  • Up to eight separate, additional queues for each of the eight supported forwarding classes
  • Additional multipoint queues up to three for each forwarding class for each type of multipoint traffic (broadcast, multicast, and destination unknown unicast)
  • QoS policy match criteria to map packets to a forwarding class

Each queue can have unique queue parameters to enable individual policing and rate shaping of the flow mapped to the forwarding class. Mapping flows to forwarding classes is controlled by comparing each packet to the match criteria in the policy. There is one default access ingress policy. The default policy gives all traffic equal priority with the same chance of being sent or dropped during periods of congestion.

Service Tunnel SDP Binding svt Service Distribution Point (SDP) bindings are also known as Service Tunnels. Distributed VLL (Virtual Leased Line) service and VPLS traffic is transported from one edge router to another edge router by circuits aggregated in unidirectional service tunnels. Service tunnels terminate at a destination router, which directs packets to the correct service egress access interfaces on that device. Service tunnels can be configured to use Generic Routing Encapsulation (GRE) or MPLS LSPs.

The service tunnels that encapsulate the data between the two edge routers appear as Layer 2 paths to the service data, although the data is really traversing an IP or IP/MPLS core.

Shelf Shelf equipment The shelf component on an Alcatel-Lucent router has characteristics such as type of shelf, number of card slots, number of installed fan trays, and so on.
