110 Deploying and Managing IP over WDM Networks WINMAN operator (from actors) SMS (from actors) • Modify ICS UC. The modify integrated connectivity service UC is used when one or more service parameters need to be changed. The WINMAN operator and the SMS can request the change of service characteristics. Figure 6.8 depicts the UCs involved in modifying a connectivity service within WINMAN. Two separate UCs are defined for supporting the modification of connectivity services: 1. Modify ICS by the SMS. The main flow described in this UC is a modification of the service in automatic mode. The modification is done after a single request from the SMS. A step-by-step modification, driven by several requests from the SMS, is described as an alternative flow. Modify ICS Figure 6.8 Modify ICS UC.

The WINMAN Management System Concept 111 2. Modify ICS by the WINMAN operator. This UC describes how the WINMAN operator can modify an integrated connectivity service. The inherent flexibility in the IP layer allows for the modification of a service without service outages. This means that with the ICS in active state, the WINMAN system can implement the changes on the network. The following modifications of a service have been identified: 1. Change of the SLSs, such as, but not limited to, bandwidth, reliability (availability or protection level), delay, jitter, or packet loss. This modification may not require changes in the managed network, if the existing IP path that supports the service meets the new QoS parameters. 2. Add or remove a leg to a point-to-multipoint or multipoint-tomultipoint service. This functionality will not be included if theses services are not included in WINMAN. 3. Change the scheduling (initial or final time) of the service. The SMS or the WINMAN operator can trigger the UC. In the first case, the process will be automatic; that is, the SMS requests WINMAN to modify the service parameters, and WINMAN carries out the needed actions. In the other case, the operator can have more control over the process. The modify ICS request may or may not cause changes in the network connectivity. According to the requested modification, the service may have to be rerouted through a new path that can satisfy the new SLSs. During the modification, the service may become unavailable for some time. • Delete ICS UC. This UC describes the opposite of the provide ICS UC. This is the summary UC described in the most general terms. Figure 6.9 depicts the UCs involved in deleting an ICS. Two separate UCs are defined for supporting the deletion of ICSs: 1. Delete ICS by the service management system (SMS). The SMS requests from the WINMAN system the deletion of an ICS. It is assumed that an ICS is deactivated and released at the end of a session. 2. Delete ICS by the WINMAN operator. The operator requests from the WINMAN system the deletion of an ICS. It is assumed that an ICS is deactivated and released at the end of a session. The following processes are distinguished when deleting the ICS: 1. Verify ICS request. This step describes the WINMAN system responsibilities for the verification and validation of the ICS
