Preferred Architecture for Cisco Collaboration Release 15 On-Premises Deployments PAGE 7
Introduction

Architectural Overview The Cisco Collaboration on-premises Preferred Architecture provides end-to-end collaboration targeted for a wide range of customers. This architecture incorporates high availability for critical applications. The consistent user experience provided by the overall architecture facilitates quick user adoption. Additionally, this architecture supports an advanced set of collaboration services that extend to mobile workers, partners, and customers through the following key services: • Voice communications • Instant messaging and presence • High-definition video and content sharing • Rich media conferencing • Collaboration services for mobile and remote workers • Business-to-business voice and video communications • Unified voice messaging • Customer care for midmarket deployments Because of the adaptable nature of Cisco endpoints and their support for IP networks, this architecture enables an organization to use its current data network to support both voice and video calls. The Preferred Architecture provides a holistic approach to bandwidth management, incorporating an end-to-end Quality of Service (QoS) architecture, call admission control, and video rate adaptation and resiliency mechanisms to ensure the best possible user experience for deploying pervasive video over managed and unmanaged networks. The Cisco Collaboration on-premises PA, shown in Figure 2, provides highly available and secure centralized services for enterprise and midmarket deployments. These services extend easily to remote offices and mobile workers, providing availability of critical services even if communication to headquarters is lost. Centralized services also simplify management and administration of an organization's collaboration deployment.
