Glossary

  • Adaptive Private Networking (Oracle SD-WAN Edge)

As used in this guide, the name for the whole network that includes the Adaptive Private Networking Appliances, the Wide Area Network, the conduits between peer APNAs, as well as other network application services. Oracle SD-WAN Edge is configured from a single APNA, which is the Network Control Node (NCN).

  • Adaptive Private Networking Appliance (APNA)

The general name for a specific Oracle network appliance, also occasionally referred to as a Appliance.

  • Client Node (Client)

A Oracle Client Node is an Oracle SD-WAN Edge appliance that is located across the Oracle network from the NCN. Although an NCN may potentially have multiple clients, each client has only one NCN.

  • Conduit Service

The Conduit service is a logical combination of one or more paths, and is the typical mode for enterprise site-to-site intranet traffic, utilizing the full value of the Oracle's Adaptive Private Networking. In this mode, depending on configuration, the traffic is actively managed across multiple WAN links to create an end to end conduit.

  • Ethernet Interface

A physical or configurable interface of the APNA. For example, the T730 has nine userdefined Ethernet Gigabit interfaces, plus a predefined Management interface.

  • Flow

A flow is a stateful instance (memory) used to track and treat application traffic from its source to its destination across Oracle SD-WAN Edge. The properties of a particular flow are derived from the routes, rules, and service that the traffic flow matches.

  • Internet Network Service

The Internet Service is for traffic between an enterprise user and sites on the public Internet. Traffic of this type is not encapsulated. During times of congestion, Oracle SD-WAN Edge does actively manage bandwidth by rate-limiting Internet traffic relative to the conduit and intranet traffic as per the configuration established by the administrator.

  • Intranet Network Service

The Intranet Service is for any portion of enterprise Intranet traffic that has not been defined for transmission across an Oracle SD-WAN Edge conduit. As with Internet traffic, it remains unencapsulated, and Oracle SD-WAN Edge manages bandwidth by rate-limiting this traffic relative to other service types during times of congestion. Note that under certain conditions, and if configured for Intranet Fallback on the Conduit, traffic between a pair of APNAs that ordinarily travels via a conduit may instead be treated as Intranet to maintain network reliability.

  • Network Control Node (NCN)

The NCN is the central APNA that acts as the master controller of Oracle SD-WAN Edge, as well as the central point of administration for the client nodes. The NCN's primary purpose is to establish and utilize a conduit with one or more Oracle Client Nodes across the network for enterprise site-tosite communications. A particular NCN can administer and have conduits to multiple Client Nodes.

  • Network Service

A logical set of operations performed on the traffic as it uses Oracle SD-WAN Edge. The set of services supported are Bypass, Passthrough, Internet, Intranet, and Conduit.

  • Passthrough Network Service

Traffic directed to the Passthrough service includes broadcasts, ARPs and other nonIPv4 traffic, as well as traffic on the APNA's local subnet, specifically configured subnets, or rules applied by the network administrator. The APNA does not delay, shape or modify

this traffic. Because the Oracle service does not hinder this traffic, the network administrator must be sure that Passthrough traffic does not consume substantial resources on the WAN links which the APNA is configured to use for other services. Example: Passthrough may be used if a host is located on the WAN side of the APNA, but access to the host does not impact the APNA's specific WAN links. Think of the special management IP of the WAN link router as a typical example of a proper explicit use of Passthrough.

  • Redundant Oracle SD-WAN Edge Control Protocol (RACP)

The protocol developed by Oracle to provide functionality for two high availability (HA)

APNA's to communicate availability information.

  • Rule

A Oracle Networking Service equivalent of a typical router access control list or filter mask. A rule defines match criteria and properties for IP flows. Flows that match those criteria use the service with which the rule is associated.

  • Oracle Path Oracle Conduit Class

A Oracle Path is a logical link between two Oracle Virtual IP addresses (VIP). A Class is a queued service point into a Oracle conduit. The Class to which traffic is assigned determines its share of the conduit bandwidth, permitted queue depth, and its priority, relative to other traffic, for Oracle Network resources.

  • TCP Termination

TCP termination provides the ability to split a single TCP connection into three separate TCP connections all managed and maintained by the Oracle SD-WAN Edge. TCP termination is only used for conduit traffic.

  • Traffic Service Types

Traffic Service Types apply while the system is in the Active state noted above.

  • Trust Relay Points (TRP)

A Cisco Systems software function implemented in voice over IP networks that provides multiple voice capabilities, such as transversing trusted firewalls.

  • Trusted WAN Port

Appliance port processing network traffic that is protected by a firewall, performing as if it were a traditional WAN port.

  • Untrusted WAN Interface

Appliance interface processing network segment traffic that is not being protected by a firewall. Non-conduit traffic from the WAN is unable to communicate to any network interface inside of the appliance. The segment is entirely isolated from the rest of the network with the exception of the APNs own 128 bit AES encrypted paths.

  • WAN Link

The general term for an enterprise's connection to a WAN. These WAN links are typically connected to router ports. Some examples of WAN Links are T1, DSL, or Frame Relay.
