The request for configuration data may be relayed from the Ethernet-layer OAM&P protocol to a configuration protocol. The request for configuration data may be transmitted from the provider edge device to a configuration repository server via the configuration protocol. The configuration repository server may transmit the requested configuration data to the provider edge device via the configuration protocol. The provider edge device may relay the configuration data from the configuration protocol to the Ethernet-layer OAM&P protocol and transmit the configuration data to a customer edge device via the Ethernet-layer OAM&P protocol. The customer edge device may automatically configure itself using the configuration data.

Example Embodiments
A customer edge device may be automatically configured via an Ethernet-layer operations, administration, maintenance, and provisioning (OAM&P) protocol and a configuration protocol. The customer edge device may request configuration data via an Ethernet-layer OAM&P protocol. In one example, the Ethernet-layer OAM&P protocol may be an extension of IEEE standard 802.3ah link operations, administration, and maintenance (OAM). A provider edge device may transmit the request to a server via the configuration protocol. The server may transmit customer edge device configuration data via the configuration protocol based on the request. The provider edge device may transmit the configuration data to the customer edge device via the Ethernet-layer OAM&P protocol. The customer edge device may automatically configure itself using the configuration data.
FIG. 1 illustrates one example embodiment of a system 10 included in a network 11. In one example, the system 10 is configured to allow auto-configuration of customer edge (CE) devices CE1, CE2. In one example, a CE device may be a bridge, which may also include a host computing device or devices. In other examples, a CE device may be a single or various devices suitable for directing network traffic. For automatic configuration, or auto-configuration, a CE device configures itself once the appropriate configuration data is received by the CE device.
In one example, the CE devices CE1, CE2 may be used in a Carrier Ethernet-based network, such as a Metro Ethernet Network (MEN). In an example MEN, a service provider may provide various network services to a number of customers. Such services may be intranet, extranet, virtual private network (VPNs), and virtual local area network (VLAN) services. Each customer may use at least one CE device for transferring network traffic between the customer site and the network.
The CE devices CE1, CE2 shown in system 10 of FIG. 1 may be used in an Ethernet layer 2 (L2) VPN, or other L2-based network configuration, and thus, a CE device may be configured in order to coordinate Ethernet L2 service characteristics. “Layer 2” refers to layer 2 of the Open Systems Interconnection Basic Reference Model. L2, also known as the “Data Link Layer” to those of skill in the art, may respond to service requests from the “network layer,” or “layer 3,” and issues service requests to the “physical layer,” or “layer 1.” The CE devices CE1, CE2 may be used in other layers.
L2 may be used to transfer data between adjacent network nodes in a wide area network or between nodes on the same local area network segment. L2 may provide the functional and procedural manners to transfer data between network entities and may provide detection and correction of errors that may occur in layer 1. Examples of L2 protocols are Ethernet, point-to-point protocol (PPP), high-level data link control (HDLC), and advanced data communication control procedures (ADCCP) for point-to-point connections. Other standards or non-standard data transfer protocols may be used.
In example embodiments, the CE devices CE1, CE2 may be implemented as bridges (e.g., switches) or on-site customer devices. A CE device is configured in order to operate properly on a network. In example embodiments, CE device configuration may include each CE device receiving configuration data informing each CE device of the Ethernet L2 services to be enforced or optimized. For example, committed information rates per virtual circuit may be communicated to a CE device, and set during configuration. Various other service-based parameters may be set during CE device configuration, such as customer edge VLANs, Ethernet virtual connection (EVC) names, and committed burst size.
The CE devices CE1, CE2 may be bridges including servers, processors, computers, cards, or other now known or later developed computer network device. In the example shown in FIG. 1, the CE device CE1 includes a processor 12 and a memory 14. Similarly, in one example, the CE device CE2 may include a processor 16 and a memory 18. The CE devices CE1, CE2 are shown as being connected to a PE device PE1 through connections 13, 15, respectively. In one example, the PE device PE1 may be a bridge, or other suitable device or devices configured to manipulate the flow of network traffic over Ethernet L2 services. The PE device PE1 is shown as being connected to a server 20 through connection 17 and to the network 11 through connection 19. Each of the connections 13, 15, 17, 19 may be a single or series of network connections linking the devices to one another, such as in the manner described. Any computer network link or communications path may be used, such as direct or indirect linking.
In one example, the server 20 may be a configuration repository server. The configuration repository server 20 may include a processor 22 and a memory 24. The memory 24 of the configuration repository server 20 may store various CE device configurations, which may be used by a particular CE device for auto-configuration.
CE devices may be configured after connection to a network, such as after a CE device has been connected to and authorized by a PE device that is part of a network. In FIG. 1, the CE device CE1 may be initially connected to the PE device PE1 through the connection 13 of the system 10. The system 10 may be part of a portion of an Ethernet-layer network, which in one example may be the network 11. The CE device CE1 and the PE device PE1 may communicate with one another through an Ethernet-layer OAM&P protocol during configuration of the CE device CE1 as indicated by an arrow 23. For example, the CE device CE1 may request configuration data from the PE device PE1 through an Ethernet-layer OAM&P protocol.
In one example, the Ethernet-layer OAM&P protocol may be an Ethernet local management interface (E-LMI) protocol, which is a protocol used to enable a CE device to request and receive status and service attributes information so that it may configure itself to access Ethernet services, such as Metro Ethernet services. For example, the E-LMI protocol may be that as defined by the Metro Ethernet Forum Technical Specification MEF 16 (“MEF 16 Specification”).
The PE device PE1 device and configuration repository server 20 may communicate with one another through the connection 17 according to a configuration protocol, as indicated by an arrow 25. In one example, the configuration protocol may be an authentication, authorization, and accounting (AAA) protocol. In another example, the configuration protocol may be the customer premise equipment (CPE) wide area network (WAN) management protocol (CWMP) or other suitable protocol. Other protocols may be used as either the CWMP or the AAA protocol, such as remote authentication dial in user service (RADIUS), Diameter, service gateway interface (SGI), terminal access controller access-control system (TACACS), TACACS+, etc.
In one example, the CE device CE1 may be initially connected to the system 10 and request configuration via an Ethernet-based OAM&P protocol, as indicated by an arrow 27 through the connection 13. For example, this CE device CE1 may transmit a request for configuration data according to the E-LMI protocol through a “status enquiry” message as defined by the MEF 16 Specification. The status enquiry message may request a “full status” report, which provides the CE device CE1 information allowing the CE device CE1 to be auto-configured. In an alternative example, the PE device PE1 may trigger the CE device CE1 to request configuration data as indicated by an arrow 21. In one example, the PE device may transmit an asynchronous status message to the CE device CE1, which may cause the CE device to transmit a configuration request, such as a status enquiry message.
Upon receiving the E-LMI protocol status enquiry, the PE device PE1 may execute a CE-identification scheme, which may be stored in a memory 28 of PE device PE1 and executed on a processor 26 of the PE device PE1. This allows identification of a particular CE device requesting configuration data to ensure the CE device is authorized to be part of the network. The PE device may also execute an authentication/authorization application to authenticate and authorize the presence of a CE device on the network 11. In one example, the PE device may authenticate and authorize a CE device based on an identification of the CE device, such as a media access control (MAC) address, previously stored by the PE device upon initial connection of the CE device. The authentication/authorization application may be implemented through various suitable manners, such as port-based, IEEE 802.1-based, Dynamic Host Configuration Protocol (DHCP), Point-to-Point Protocol over Ethernet (PPPoE), and E-LMI with extensions, for example.
Once the status enquiry is received by the PE device PE1, the PE device PE1 relays the information received via the E-LMI protocol from the CE device CE1, such as the status enquiry, to the configuration protocol. This protocol relay allows the proper conversion of data encoding, and thus allows the PE device PE1 to properly communicate with the configuration repository server 20. In one example, the protocol transfer may be performed through use of a processor 26 and a memory 28 of the PE device PE1. In one example, the PE device PE1 may rely on both data received via the E-LMI protocol and the authentication/authorization application to fully identify the CE device CE1.
The PE device PE1 may transmit the request for configuration data to the configuration repository server 20 via the configuration protocol through the connection 17, as indicated by an arrow 31. This request may include identification of the CE device CE1 to the configuration server 20. The processor 22 of the configuration repository server 20 may process the request received from the PE device PE1. The configuration repository server 20 may also store various CE device configurations in the memory 24. Upon receipt of request for configuration data, the configuration repository server 20 may determine the identity of the CE device CE1. Alternatively, the PE device PE1 indicates the identity. The configuration repository server 20 may then determine the appropriate configuration data stored in the memory 24 of the configuration repository server to transmit for receipt by the CE device CE1 for auto-configuration.
Once the appropriate CE configuration data is determined, the configuration repository server 20 may transmit the CE configuration data through the connection 17, such as the information related to a full status report. This information is transmitted to the PE device PE1 via the configuration protocol as indicated by an arrow 29. Upon receipt of the of CE configuration data, the PE device PE1 may transfer the data received according to configuration protocol to the E-LMI protocol. The PE device PE1 may then transmit the configuration data, as indicated by an arrow 33, through the connection 13, such as the full status report to the CE Device CE1, allowing auto-configuration of the CE device CE1.
In one example, the PE device may receive the CE configuration data via the configuration protocol in the form of a configuration protocol message and validate the configuration protocol message. The PE device may parse and extract the configuration data contained in the configuration protocol message. The PE device may interpret and translate the configuration information into a format that may be implemented by the OAM&P Ethernet protocol. The PE device may also populate the translated configuration information into the appropriate OAM&P Ethernet protocol message or messages and transmit those to the CE.
In one example, the CE device CE2 may be configured in a manner similar to CE device CE1. The CE device CE2 may transmit a request for CE configuration data from the PE device PE1 via an Ethernet-layer OAM&P protocol, as indicated by an arrow 35, such as E-LMI protocol, for example. The PE device PE1 may relay the request from the Ethernet-layer protocol to the configuration protocol. The request may then be transmitted to the configuration repository server 20, which may, in response, transmit the requested CE configuration data to the PE device PE1 via the configuration protocol. The PE device PE1 may then transfer the CE configuration data from the configuration protocol to the Ethernet-layer OAM&P protocol and transmit the CE configuration data to the CE device CE2 for auto-configuration.
In one example, the system 10 may include a plurality of PE devices with each PE device connected to a plurality of CE devices according to a particular network configuration. The plurality of PE devices may share a commonly-connected server or be independently connected to a number of servers, such as the configuration repository server 20, configured to store data for various CE configurations.
In one example, the interaction of the CE devices CE1, CE2, PE device PE1, and configuration repository server 20 described and shown in FIG. 1 allows various options that are unavailable when a PE device is responsible for storing configuration data for CE devices. For example, through storage of CE device configuration data in the configuration repository server 20, a management channel may be extended to a CE device without a layer 3 topology overlaid for the purpose of accessing the CE device configuration. Furthermore, the configuration of the system 10 described in regard to FIG. 1 also allows a CE device to be re-configured depending on the service attributes, thus allowing a CE device to be re-used without being replaced by a CE device having a different configuration. In another example, the configuration of system 10 described above may allow memory on the PE device to be used for purposes other than storing CE device configuration data. In alternative embodiments, the PE device may store at least a portion of the CE configuration data.
FIG. 2 shows an example method for configuring a CE device in a network, such as the network 11 configured as a MEN or a different network. The method may include an act 100 of requesting CE configuration data via an Ethernet-layer OAM&P protocol. In one example, the act 100 may be performed by a CE device, such as the CE device CE1 transmitting a configuration data request to the PE device PE1 through an E-LMI protocol. The method may also include an act 102 of authenticating and authorizing a presence of a CE device on a network based on the request for configuration data. In one example, the act 102 may be performed by a PE device, such as PE device PE1, authenticating and authorizing presence of the CE device CE1 on the network 11 based on the request for CE configuration data sent by the CE1 device in a manner similar to that described with regard to FIG. 1.
The method may also include an act 104 of relaying the request for CE configuration data from the Ethernet-layer OAM&P protocol to a configuration protocol such as the AAA protocol or CWMP. In one example, the act 104 may be performed by a PE device such as the PE device PE1 described with regard to FIG. 1. Alternatively, the PE device passes the request to another device or network node for transfer between protocols. The method may also include an act 106 of transmitting a request for CE device configuration data according to the configuration protocol. In one example, the act 106 may be performed with the PE device PE1 transmitting the request for CE configuration data to the repository configuration server 20.
The method may also include an act 108 of transmitting the requested CE device configuration data via the configuration protocol. In one example, the act 108 may be performed by the configuration repository server 20 transmitting the CE device configuration data to the PE device PE1 based on the CE configuration data request via the configuration protocol as discussed in regard to FIG. 1. The method may also include an act 110 of relaying the requested CE device configuration data from the configuration protocol to the Ethernet-layer OAM&P protocol. In one example, the act 110 may be performed by the PE device PE1 in a manner described according to FIG. 1 in which the PE device PE1 transfers the CE configuration data from the configuration protocol to the Ethernet-layer OAM&P protocol, such as the E-LMI protocol.
The method may also include an act 112 of transmitting the requested configuration data via an Ethernet-layer OAM&P protocol. In one example, the act 112 may be performed in the manner described according to FIG. 1, such as the PE device PE1 transmitting the CE configuration data to the CE device via the Ethernet-layer OAM&P protocol. The method may also include an act 114 of performing a CE device configuration using CE configuration data received. In one example, the act 114 may be performed by a CE device, such as the CE device CE1 described in regard to FIG. 1. The CE device CE1 may auto-configure itself using the requested CE device configuration data. One or more operation parameters may be set based on the configuration data.
FIG. 3 shows an example method of relaying a CE configuration data request from an Ethernet-layer OAM&P protocol to a configuration protocol. In one example, the method of FIG. 3 may be performed by a PE device, such as the PE device PE1 of FIG. 1. The method may include an act 200 of determining CE configuration data request parameters in the CE configuration data request. The method may further include an act 202 of extracting the request parameters from the CE configuration data request. The method may further include an act 204 of inserting the extracted parameters into a CE configuration data request formatted according to the configuration protocol. In one example, the method of FIG. 3 may be used in the act 104 of the example method of FIG. 2.
FIG. 4 shows an example method of relaying CE configuration data from a configuration protocol to an Ethernet-layer OAM&P protocol. The method of FIG. 4 may be performed by a PE device such as the PE device of FIG. 1. The method may include an act 300 of validating a configuration protocol message containing requested CE configuration data. The validation of the act 300 may also include parsing the CE configuration data contained in the configuration protocol message. The method may further include an act 302 of extracting the configuration data contained in the configuration protocol message. The method may further include an act 304 of interpreting the CE configuration data. The method may further include an act 306 of translating the CE configuration data into a format that may be implemented by an Ethernet-layer OAM&P protocol. The method may include an act 308 of populating the translated configuration information into the appropriate OAM&P Ethernet protocol message, which may be transmitted to the requesting CE device. In one example, the method of FIG. 4 may be implemented in the act 110 of the example method of FIG. 2.
