- 2. Agenda Lync Server Standard _1 Lync Server Enterprise _2 Ruoli in Lync Server _3 Lync Server Clients _4
- 3. Lync Server Standard Standard Edition : • Smaller organizations and remote locations • Approximately 5000 homed users • You cannot pool Standard Edition Front End Servers • Database : collocated SQL Server Express version • You can have stand-alone Mediation Servers, Edge Servers, Archiving Servers, and Monitoring Servers • The A/V Conferencing Server remain collocated http://technet.microsoft.com/en-us/library/gg398085.aspx
- 4. Lync Server Enterprise Enterprise Edition : • An Enterprise Edition server has all of the Standard Edition server features; however it provides scalability and high availability • It is intended to allow an high number of users in any location/configuration
- 5. Licensing Server/Client Access License (CAL) model : • A license is required for each operating system environment running Lync Server • A CAL is required for each user or device accessing the Lync Server • A server license is required for each instance of the Front End ServerAll other roles are considered additional software and do not require a license http://lync.microsoft.com/en-us/HowToBuy/Pages/pricing-licensing.aspx Server license offerings Estimated price Lync Server 2010 Standard Edition $699 Lync Server 2010 Enterprise Edition $3,999
- 6. Ruoli in Lync Server Front End Edge Back End Group Chat Central Management Mediation Archiving and Monitoring Reach Application Sharing Audio/Video Conferencing Survivable Branch Appliance Role Lync Web Application Unified Communications Application Director Role Web Conferencing
- 7. Ruoli «secondari» • Lync Web Application : Maintains the new Silverlight-based Lync Web App client • Reach Application Sharing : this role handles sharing of applications between users while chatting or conferencing • Unified Communications Application Server : helps with recording voicemails and passing them to Exchange • Web Conferencing : Provides a foundation for hosting Web conferences (with integrated audio/video from the Audio/Video Conferencing Server)
- 9. Front End The Front End Server is the core server role, runs basic Lync functions User authentication and registration Presence information and contact card exchange Address book services and distribution list expansion IM functionality, including multiparty IM conferences Web conferencing and application sharing (if deployed) Application hosting services Central Management Server (basic configuration data to all servers running Lync Server 2010)
- 10. Back End • The Back End Servers are database servers running Microsoft SQL Server that provide the database services for the Front End pool • You can have a single Back End Server, but a cluster of two or more servers is recommended for failover • Back End Servers do not run any Lync Server software • If you already have a SQL Server cluster that you are using for other applications, you can also use this cluster for Lync Server 2010
- 11. Central Management Store The CMS is a centralized database of all Lync Server settings in the form of topology, configurations and policies The repository is implemented as an SQL database (xds) The configuration information is stored as XML documents in the database Is replicated to all servers in a deployment, including edge servers The access to the repository is provided through and limited to a Microsoft Lync Server 2010 Dynamic Link Library (DLL) Microsoft.Rtc.Management.Core.dll The DLL also enforces validations and scope resolutions etc. Runs on the Central Management Server (collocated on one front-end pool or on a Standard Edition server) • Attributes such as a user’s phone number is still stored in Active Directory • Server configurations or the services are now stored in a Central Management Store
- 12. Modifica del CMS • The way to modify information in CMS is by using one of the tools: Topology Builder (TB) Lync Server Management Shell (PS) Lync Server Control Panel (LsCP) • CMS includes the key functionality of validating any information being written to it before it commits to the database • CMS operates in a single master/multiple replica system In every Lync deployment there is only a single master CMS
- 14. Replica del CMS • All writes are done to the CMS master • All Lync Server 2010 servers have a local replica of CMS • Replicas update from the master • This process is called replication • The process consists of • copying information between directories from the master to the replicas • applying the changes received to the replica • report status back to the master • The CMS master uses a directory structure shared with other Lync Server defined in the topology document • Each replica uses a directory structure in the file share • Each 60 seconds a task is run to determine if a change has been made to the CMS master and needs to be replicated • For Edge servers the file copy is performed over an HTTPS channel
- 15. Vantaggi del CMS The centralized management store Reduces Lync Server’s reliance on Active Directory Enables an edge server to be configured as part of the main deployment Is automatically replicated to each server Non primary survivable servers are able to take over their designated roles when required Enables a branch office server to continue to process calls even if its link to the pool is lost

- 17. Lync Server Archiving • The Archiving role primarily serves the purposes of legal compliance • Centrally searchable archive • Archive communications across both IM and meetings • A single Archiving Server is capable of handling up to 300,000 users • It is common to collocate the Archiving role with the Monitoring role • The Archiving role supports redundancy and failover • The Archiving Server role can archive the following content: • Peer-to-peer instant messages • Multiparty instant messages • Web conferences, including uploaded content and events
- 18. Configurazione del ruolo Archiving • Most of the configuration is done automatically by the Topology Builder tool • Configuration and administration can be done from GUI or the Lync Server management shell Default Site policy User policy Global Policy
- 19. Lync Server Monitoring • Monitoring role collects and manages information from the Front End,Mediation, and other server roles • Stores the information in a database that is separate from the one used by the front end • Uses SQL Server Reporting Services to create reports related to call quality and metrics • A single monitoring server can monitor several pools of front end
- 20. Configurazione del ruolo Monitoring Once the report pack for SQL Server Reporting Services is installed, we can proceed to using the Lync Server 2010 Control Panel to configure monitoring for the Lync environment User experience which provides qualitative Test the reports via: By default, there is only one global policy and quantitative analysis of every call http://serverFQDN/Reports
- 21. Conferencing Web IM Audio A/V Dial-In Conferencing Conferencing Conferencing Conferencing Conferencing Web conferencing Enables users to Allows users to join is integrated with Audio conferencing have real-time the audio portion the overall with Lync Server Lync Server 2010 audio and video of a conference by enterprise 2010 enables users enables IM conferences using a public messaging to schedule, join, conferencing, in without the need switched infrastructure of and manage which more than for external telephone network Lync Server conferences from two parties services, such as (PSTN) phone 2010Users can personal communicate in a the Microsoft Live without requiring a share and computers, web, single IM session Meeting service or third party audio collaborate on phones, and a third-party audio conferencing documents ad mobile devices bridge provider share their desktop

- 25. Audio e Dial-In Conferencing • Lync Server 2010 has dial-in conferencing support on top of an existing voice infrastructure where IP/PSTN gateways are in place and functional • An organization can continue to leverage its existing phone handsets and PBX while still using the rich dial-in conferencing meeting and scheduling experience • This enables organizations to begin using the audio conferencing service without a significant investment or change to user behavior • Users can continue to use their current handsets, but gain the capability to schedule and join meetings using a Lync client
- 26. Lync Autodial • Users that are already authenticated to Active Directory through the Lync client do not need to manually dial the access number and enter an extension and PIN • Lync can even dial the user’s work number automatically

- 28. Director • The Director role in Lync Server is a specialized subset of the Front End Server, which provides authentication and redirection services • The primary function is to authenticate endpoints and “direct” users to the pool where their user account is homed • When a client signs in to a Director, he is first authenticated and then informed which pool to register • When external access is used, a Director serves as the next hop server between Edge Servers and the Front End pools • In Lync Server Director is a dedicated role separate from a Front End Server • Security and stability of the role by not installing unnecessary components (prevent administrators or help desk users from homing new user accounts on a Director)
- 29. Edge • Lync Server Edge Server enables remote access to the internal infrastructure • Federation with partner organizations or public IM providers • Deploy both in a standalone scenario and in a high-availability deployment where multiple Edge Servers are used • Reverse proxy server is required
- 30. Edge Services The Edge Server comprises three separate subroles : • Access Edge Server • Web Conferencing Edge Server • A/V Edge Server Each role provides different functionality It might not be necessary to use all three services No database / file shares Limited set of services to make it as secure as possible Edge Servers are typically not joined to A.Ddomain, but can be if necessary
- 31. Lync Server Standard ed Enterprise
- 32. Edge Access, Web Conferencing e A/V • Access Edge service : single, trusted connection point for both outbound and inbound Session Initiation Protocol (SIP) traffic • Web Conferencing Edge service : enables external users to join meetings that are hosted on your internal Lync Server 2010 communications software deployment • A/V Edge service : makes audio, video, application sharing, and file transfer available to external users • Meetings that include external participants • Share audio and video directly with an external user • Support for desktop sharing and file transfer
- 33. Edge e Reverse Proxy • Reverse proxy is required to publish the web components services that don’t run through an Edge Server. • The reverse proxy provides remote access to the web components running on Front End Servers or Edge Servers : • Address Book • Distribution Group Expansion • Device Updates • Web Conferencing Content (Whiteboards and PowerPoint File Uploads)
- 34. Edge Installazione e Configurazione
- 35. Mediation Server • Mediation server is the central component for Enterprise Voice and dial-in conferencing • The Mediation server translates signaling between your internal Lync Server 2010 infrastructure and an IP-PBX gateway or IP-PSTN gateway, or a SIP trunk • Mapping with multiple gateways • The flow of media can also be configured to bypass the Mediation server when possible and flow directly to a gateway
- 36. Mediation Server
- 37. Media Bypass • One of original roles of the mediation server was to transcode between RealTime audio and G.711 to integrate with standards-based media gateways and PBXs • With Lync Server, calls can be sent using G.711 directly to a supported gateway or PBX • Although low bandwidth signaling (SIP) still traverses the mediation service role, higher bandwidth media (RTP) flows directly from a Lync Server endpoint to the GW/PBX, bypassing the Mediation Server role. • This change provides several benefits, including • Removes a potential single point of failure that a mediation server introduced • Reduces the number of hops a media stream takes • calls from PBX users at a branch to Lync Server users at the same branch, media now remains at the branch
- 38. Media Bypass Unique IDs • When you enable Media Bypass, a globally unique bypass ID is generated for all network sites If the bypass IDs do not match, media for the call flows through the If the two bypass IDs Mediation server at the If the two bypass match, Media Bypass is central site IDs match, media used for the call When a user makes a flows directly from When a user PSTN call, the the gateway to the Mediation server receives a call from client, bypassing the compares the bypass the PSTN, the user’s ID of the client subnet Mediation server client compares its with the bypass ID of the gateway subnet bypass ID to that of the PSTN gateway
- 39. Survivable Branch Appliance e Server • The Survivable Branch Appliance (SBA) is a server appliance with an embedded PSTN gateway running Windows 2008 R2 and Lync Server 2010 • It is designed for branch sites that host between 25 and 1,000 users • The SBA can provide basic phone services to users at the branch site when the wide area network (WAN) link to the Lync Server 2010 central site is down • The Survivable Branch Server is a Windows server that has Lync Server 2010 Registrar and Mediation server software installed • It is designed for branch sites that host between 1,000 and 5,000 users who lack a resilient WAN connection and have trained Lync Server 2010 administrators available • It must be configured to connect to either an IP/PSTN gateway or a SIP trunk to a telephone service provider
- 40. SBA Servizi Disponibili e Non Disponibili The following services are available in the event of PSTN and other voice services unavailable in a WAN outage: The following services are Hold, retrieve, transfer IM/V/W conferencing Authentication and authorization a WAN outage: Presence Call forward, simul-ring, boss- admin Call detail records Update call forwarding setting Intrasite IM and A/V Response group service PSTN audio conferencing
- 41. Enterprise Voice • Enterprise Voice is Microsoft’s software powered Voice over Internet Protocol (VoIP) solution • Because VoIP sessions can traverse network address translations (NATs) and firewalls, users working at home or traveling can use the Internet to communicate with coworker • This creates the opportunity to prevent incurring long-distance charges without the use of a virtual private network (VPN)
- 42. Voice Routing Dial Plan A dial plan contains a set of normalization rules to convert dial strings to a routable format and is assigned to users Normalization Rules Associated with a dial plan and converts the digits a user might dial into a common format that is then routable by the system Voice Policies Determines what voice features users are allowed to use Routes Are used in Lync Server to direct calls through a specified gateway or a set of gateways PSTN Usages Usages are a class of call that is then associated with voice policies Gateways Any object that Lync Server sends calls to can be considered a gateway Trunk Configuration A logical connection representing the connection between Lync and a PSTN gateway, IP-PBX, or Internet Telephony Service Provider. Translation Rules Rules associated with a trunk configuration to manipulate dial strings before being sent across a trunk
- 43. Voice Features Enables users to place a call on hold and then pick up that same call at another location or extension Call Park Direct calls to unassigned numbers to an attendant or operator Unassigned Numbers Administrators can define ranges of unassigned numbers and an action that occurs when someone dials one of those numbers Enables clients to determine whether an audio or video call can actually be established based on available network bandwidth Call Admission Control Media Bypass Enhanced 911 provides the caller’s telephone number and street address to a dispatcher automaticallyThis is an advantage over Enhanced 911 traditional 911 service that requires the caller to provide an address where assistance is required You can route and queue incoming calls to designated persons for special purposes, such as customer service Response Group Service
