Abstract This document introduces a notification protocol as a specified particular case of the notification mechanisms used by the Lemonade profile [LEMONADEPROFILEBIS] in [NOTIFICATIONS]. This document also discusses the use of Lemonade notifications to implement server to server notifications. Conventions used in this document Maes Expires December 2006 [Page 1]
<Lemonade Notification Protocol> June 2006 In examples, "C:" and "S:" indicate lines sent by the client and server respectively. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. An implementation is not compliant if it fails to satisfy one or more of the MUST or REQUIRED level requirements for the protocol(s) it implements. An implementation that satisfies all the MUST or REQUIRED level and all the SHOULD level requirements for a protocol is said to be "unconditionally compliant" to that protocol; one that satisfies all the MUST level requirements but not all the SHOULD level requirements is said to be "conditionally compliant." When describing the general syntax, some definitions are omitted as they are defined in [RFC3501].

<Lemonade Notification Protocol> June 2006 2. Usage Model 2.1. Notification protocol in Lemonade Profile Bis The target logical architectures involving the LEMONADE Profile and notifications are discussed in [LEMONADEPROFILEBIS]. Figure 1 illustrates how notification and filtering can be introduced in the context of LEMONADE profile bis. +--------------+_____________ Maes Expires December 2006 [Page 3]

In Figure 1, the notification protocol MAY be used between NF in the Lemonade IMAP Store and a compliant Notification mechanism. Note that in general [LEMONADEPROFILEBIS] does not mandate the use of the present notification protocol. It is also possible that NF interacts with the notification mechanisms via protocols specific to each of the notification mechanisms. The present draft solely provides a generic protocol to do so that the notification mechanism MAY support. 2.2. Notification protocol for generic server to server notifications As discussed in [NOTIFICATIONS], with server to server notifications, a messaging system (e.g. email server, voice mail system, etc.) submits alerts, which describe potential notification events, regarding an end user mailbox status change (e.g. new message has arrived, mailbox is full, etc.). These alerts are sent to a notification mechanisms, which may, in turn, generate an end user alert notification. Maes Expires December 2006 [Page 4]
<Lemonade Notification Protocol> June 2006 The present notification protocol MAY be used as a generic way to interface with each server to server notification mechanisms. As described in {NOTIFICATIONS], it is also possible to interact with the notification mechanisms via protocols specific to each of the notification mechanism. The present draft solely provides a generic protocol to do so that the notification mechanism MAY support. The figure 2 depicts the server to server notification scope: +--------+ +--------+ New | | | SMS | Message | Email | \ |Gateway | -------> |Server 1| \ _ | | +--------+ \ /| +--------+ ^ \ / | \ / ^ | \ +--------------+ / | +--------+ +--------+ | _|+-------------|+ / | | MWI | Read | Voice | | || |/ | |Gateway | Message | Mail |-------->| Notification |------->| | -------> | Server | | ^ _ +| Mechanisms |\ ^ | +--------+ +--------+ | | /| +--------------- \ | | | |/ \ \| | | / ^ \ ^ \ | |/| | \ | |\| +--------+ / | | \ | | \ +--------+ Mailbox | | /| | | \| | |\ | Wap | Full | Email |/ | | | ^ \ | |_|| Push | -------> |Server 2| | | | | |\| | |Gateway | +--------+ | | | | | \ | +--------+ | | | | | |\| | | | | | | \ | | | | | | |\ | | | | | | |_|+--------+ | | | | | | | | IM | | | | | | | | |Gateway | | | | | | | | | | | | | | | | | +--------+ | | | | | | | Server to OTHER Server PROTOCOLS Notifications Figure 2: Scope of server to server notifications 3.

<Lemonade Notification Protocol> June 2006 The notification protocol MUST follow the [PARLAYXMULTIMEDIA] protocol (over SOAP). 3.1. Protocol details and guidelines <Editors note: To be Done Security Considerations Notifications must be secured (when useful information is sent) and integrity should be checkable. It should be possible to authenticate sender and prevent Denial of Service attack via notifications.
