Topic 6, Contoso, LTD 2
Contoso, Ltd. is a Canadian business law firm that currently employs 300 people. The company operates a main office in Vancouver that houses 250 employees and a branch office in Seattle that houses 50 employees. All Contoso users are Skype for Business-enabled. Contoso is launching a hybrid configuration of Office 365 to validate the cloud-based Exchange Online service.
Contoso plans to introduce a remote disaster recovery data center to host remote replicas of key services, including Active Directory Domain Services (AD DS), Skype for Business, Exchange, and files and legal software. The company also plans to acquire a small law firm in Vancouver called Litware, Inc., which has 80 employees. Litware currently uses a 10-megabit per second (Mbps) Internet connection.
Half of Litware employees will use Skype for Business services. All Skype for Business-enabled users in Litware will use Instant Messaging only. Currently, Instant Messaging concurrent usage at Litware is 50 percent during peak hours.
There is a possibility that Contoso will make two more acquisitions during the next three years. Vancouver and Seattle employees have submitted support tickets to report poor quality of outbound Skype for Business calls to external users. A user activity report collected by the help desk department is shown in the User Activity Report section.
There is a concern that in the future, the volume of Skype for Business traffic may reach up to 50 percent of the current bandwidth available in the Vancouver office.
User Activity Report

Existing Environment
The core portion of the infrastructure is located in the Vancouver data center, although the Seattle data center also has two servers (listed below) to provide redundancy of Active Directory and data services.
The following services and applications comprise Contoso’s infrastructure in Vancouver and Seattle.
Vancouver Data Center:

Seattle Data Center:

An overview of the network infrastructure of Vancouver and Seattle data centers is shown in the exhibit. (Click the Exhibit button.)
All users in the Vancouver and Seattle offices use the Microsoft Windows 8 Enterprise operating system and phones that are enabled for Enterprise voice.
Contoso expects to see a growing number of remote users. They anticipate that up to 20 percent of users in Vancouver might work remotely.
Contoso has defined a team of 35 users who will participate in a pilot deployment of the Office 365 hybrid configuration.
The offices in Vancouver and Seattle are using 5-Mbps Internet connections. Contoso has a site-to-site VPN between the Vancouver office and the Seattle office.
All external outbound calls from the Vancouver and Seattle offices are routed outside through the office in Vancouver.
Business Requirements
Contoso needs to review the existing network topology as well as the Skype for Business Server 2015 infrastructure to ensure that network capacity is sufficient to accommodate the Litware, Inc. Skype for Business users in the future.
Contoso expects to see up to 85 percent of simultaneous instant messaging, 1% of peer-to-peer traffic and 25 percent of public switched telephone network (PSTN) calls over the WAN during business hours.
All existing issues that relate to poor quality of outbound Skype for Business calls need to be addressed as well.
Contoso wants to ensure the following:
Current network bandwidth allocated to the Vancouver office is sufficient to sustain the future volume of Skype for Business traffic and guarantee high quality of Skype for Business calls.
Volume the Skype for Business traffic does not exceed 25 percent of the WAN bandwidth.
Contoso plans to redesign the existing site-to-site VPN solution between the Vancouver and Seattle offices to implement a robust and reliable WAN solution with end-to-end support of Quality of Service (QoS).
The recommended design solution needs to eliminate the possibility of WAN oversubscription by Skype for Business traffic.
The proposed Skype for Business Server 2015 solution needs to be: Scalable to accommodate the company’s future acquisitions.
Readily available for Vancouver and Seattle users.
In case of a disaster, a manual switchover of Skype for Business services to the disaster recovery datacenter should be available.
Technical Requirements
All Session Initiation Protocol traffic (SIP) traffic must be encrypted.
All external Skype for Business Server 2015 services must be protected by a firewall.
A commercial third-party certificate must be used on the external interface of Skype for Business Server 2015 Edge servers.
The Role-Based Access Control (RBAC) model will be implemented to delegate basic administrative tasks to the Skype for Business help desk team.
All maintenance of Skype for Business servers must be performed outside of business hours.
The proposed architecture solution must support interoperability between Skype for Business Server 2015 and Exchange 2013.
The Skype for Business Bandwidth Calculator must be used to analyze Skype for Business traffic. The QoS end-to-end support needs to be implemented.
