Abstract

The HTTPS protocol is used to provide a secure and uncomplicated transport medium which transmits packets in sequential order. A Hub-Spoke Model is provided that ensures for a network of n nodes, only (n - 1) routes are necessary to connect all nodes, thereby resulting in efficient transportation of information and a scalable solution.

ABSTRACT

    The HTTPS protocol is used to provide a secure and uncomplicated transport medium which transmits packets in sequential order. A Hub-Spoke Model is provided that ensures for a network of n nodes, only (n - 1) routes are necessary to connect all nodes, thereby resulting in efficient transportation of information and a scalable solution.

DETAILED DESCRIPTION

    A Unity Connection Server, such as that manufactured and sold by Cisco Systems, Inc., provides access to voice messages, whether from an Internet Protocol (IP) phone, mobile phone, web browser, email client, or a desktop client like Cisco Jabber. Each Cisco Unity Connection server has a maximum number of users that it can serve. When the messaging needs of an organization require more than one Connection server or cluster, or multiple Connection directories have to be combined, then Connection servers can be inter-linked to form a site. A Connection site can be linked with another Connection site or with a Cisco Unity site to form a Voicemail Organization. The servers that are joined to the site are referred to as locations. Within a site, each location uses the Simple Mail Transfer Protocol (SMTP) to exchange directory synchronization information and messages directly with every other location. Each location is said to be linked to every other location in the site via an intra-site link. In this way, the topology of the site is in full-mesh mode. There is only one hop for information transfer between any two locations. Figure 1 below illustrates a site of five Connection locations joined by intra-site links.

    A site with inter-linked Connection servers is also known as a Digital Network. It is not scalable primarily due to inherent complexities of SMTP which result in a complex replication algorithm and push-based mechanism that can flood recipient locations if they are not ready. Two Unity Connection sites can be connected to each other using inter-site link. This allows scaling from a maximum of ten locations to a maximum of twenty locations. However, the directory size still remains at a maximum of 100,000 objects.

    Inter-Site links can also be used to connect a Connection server or site to another Connection server or Connection Digital Network. A single location from each site acts as a gateway to the other site. All directory synchronization communications pass between the two site gateways, thereby limiting the connectivity requirements and bandwidth usage to the link between those two site gateway locations. Only one inter-site

link is supported per site. Therefore, only a single Connection site can be linked to another Connection site (Connection-Connection Interop).
