Question about NSA identifier
by John MacAuley 11 Mar '13

11 Mar '13

Peoples, I was running through the bootstrap procedure with Chin when the question of multiple NSA identifiers per software instance came up. Can someone please explain to me again why we need a one-to-one mapping between NSA (NSA identifier) and Network (Network Identifier)? It seems to be a very arbitrary restriction. I have looked through the existing WSDL definitions and there are no restrictions within it for this imposed rule. In addition, the topology schema could easily have multiple "managing" elements within the NSA object to allow it to reference multiple Network Identifiers, thereby creating a one-to-many relationship. We have a very real network requirement to support multiple network services off of a single NSA software instance. For example, off of one NSA (urn:ogf:network:surfnet.nl:2012:nsa) we can support the ETS service (urn:ogf:network:surfnet.nl:2012:ets) and an EPL service (urn:ogf:network:surfnet.nl:2012:epl). At the moment, given the current restriction, I would have to have two separate NSA. Does anyone have a reason why we can't remove this restriction? Thank you, John

Issue 76 in ogf-nsi-project: Change WSDL so connection identifier is allocated by provider NSA
by ogf-nsi-project＠googlecode.com 09 Mar '13

Status: Accepted Owner: jmacau...(a)gmail.com Labels: Type-Defect Priority-Medium FoundInVersion-2.0 FixedInVersion-2.0 New issue 76 by jmacau...(a)gmail.com: Change WSDL so connection identifier is allocated by provider NSA http://code.google.com/p/ogf-nsi-project/issues/detail?id=76 Description of Issue: In NSI CS v1.1 the requesting NSA provides the connection identifier that is used to reference the connection within the provider NSA. This implies a connection can only be identified by the tuple (Requester NSA, Provider NSA, connection ID). Furthermore, the context of a connection identifier is only addressable from the point of view of the Requesting NSA since we do not provide the ability to specify the referencing tuple within the existing protocol specification. As a result, no external entities are able to reference a reservation within a provider NSA. Resolution of Issue: E-mail list discussion in late August 2012 agreed to changing the NSI CS v2.0 protocol to allow for provider allocated connection identifiers. The following changes were agreed to: 1. In the ACK to the reservation request the Provider NSA will return the reservation ID it has associated with the new reservation. 2. The reservation confirm will still return the result of the reservation. 3. Connection Identifier specification will be relaxed to remove the need for a UUID. -- You received this message because this project is configured to send all issue notifications to this address.

Issue 71 in ogf-nsi-project: Separate summary and detailed query functionality into separate operations.

Status: Accepted Owner: jmacau...(a)gmail.com Labels: Type-Defect Priority-Medium FoundInVersion-2.0 FixedInVersion-2.0 New issue 71 by jmacau...(a)gmail.com: Separate summary and detailed query functionality into separate operations. http://code.google.com/p/ogf-nsi-project/issues/detail?id=71 Description of Issue: For consistency with the new querySummarySync() operation we are breaking they existing asynchronous query operation into two separate operations: querySummary(), and queryTree(). querySummary() would provide the existing summary query capabilities and queryTree() would provide the existing detailed query capabilities. Resolution of Issue: Modification of the WSDL to separate existing query behaviour into two separate operations. -- You received this message because this project is configured to send all issue notifications to this address.

Issue 70 in ogf-nsi-project: Add new querySummarySync operation.

Status: Accepted Owner: jmacau...(a)gmail.com Labels: Type-Defect Priority-Medium FoundInVersion-2.0 FixedInVersion-2.0 New issue 70 by jmacau...(a)gmail.com: Add new querySummarySync operation. http://code.google.com/p/ogf-nsi-project/issues/detail?id=70 Description of Issue: An NSI client (Requester Agent) allocated a private IP address behind a firewall is not capable of easily participating in the NSI protocol. NSI CS 2.0 utilizes asynchronous callbacks (endpoint specified in replyTo field) to deliver confirmation and failure messages to requesting clients. The firewall will block these asynchronous callbacks if not properly configured. To help this type of isolated client, the asynchronous callback has been made optional, but a new synchronous method of querying reservations must be provided to allow for an isolated client to poll reservation status. Discussion of Issue: Issue and solution was discussed in weekly OGF NSI working group meeting on January 23 2013. The slide package NSI-Synchronous-Query-v1 found at https://redmine.ogf.org/dmsf_files/13015?download= provides a detailed description. Resolution of Issue: Introduce a new querySummarySync message that has the behaviour for the summary query, but returned the confirmation or failure message in the SOAP response to the request. -- You received this message because this project is configured to send all issue notifications to this address.

Issue 72 in ogf-nsi-project: Remove NetworkIdType definition

Status: Accepted Owner: jmacau...(a)gmail.com Labels: Type-Defect Priority-Medium FoundInVersion-2.0 FixedInVersion-2.0 New issue 72 by jmacau...(a)gmail.com: Remove NetworkIdType definition http://code.google.com/p/ogf-nsi-project/issues/detail?id=72 Description of Issue: Original NSI CS 1.0 WSDL definition had all base identifiers such as NetworkId defined as base types (NetworkIdType) to centralize the XML type definition in a single location. This made it easer to change during all the churn in naming discussions. However, there is no only a single place NetworkId is used and a request has been made to remove the separate NetworkIdType definition. Resolution of Issue: Minutes NSI-WG conf call 23 Jan 2013 - Remove superfluous NetworkIdType since there is now only one use of the type definition and include xsd:string directly in element. -- You received this message because this project is configured to send all issue notifications to this address.

Issue 74 in ogf-nsi-project: Make ServiceExceptionType variables optional in ogf_nsi_framework_types_v2_0.xsd
