Topology Buider 9. Front EndThe Front End Server is the core server role, runs basic Lync functionsUser authentication and registrationPresence information and contact card exchangeAddress book services and distribution list expansionIM functionality, including multiparty IM conferencesWeb conferencing and application sharing (if deployed)Application hosting servicesCentral Management Server (basic configuration data to all servers running Lync Server 2010) 10. Back End The Back End Servers are databaseservers running Microsoft SQL Serverthat provide the database services forthe Front End pool You can have a single Back End Server,but a cluster of two or more servers isrecommended for failover Back End Servers do not run any LyncServer software If you already have a SQL Server clusterthat you are using for other applications,you can also use this cluster for LyncServer 2010 11. Central Management StoreThe CMS is a centralized database of all Lync Server settings in the form of topology, configurations and policiesThe repository is implemented as an SQL database (xds)The configuration information is stored as XML documents in the databaseIs replicated to all servers in a deployment, including edge serversThe access to the repository is provided through and limited to a Microsoft Lync Server 2010 Dynamic Link Library (DLL) Microsoft.Rtc.Management.Core.dllThe 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 users phone number is still stored in Active DirectoryServer 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 beingwritten 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 13. Collocazione del 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 CMSThe centralized management store Reduces Lync Servers 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 16.

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 ArchivingMost of the configuration is done automatically by the Topology Builder toolConfiguration and administration can be done from GUI or the Lync Server management shellDefaultSite policy User policyGlobal Policy 19. Lync Server Monitoring Monitoring role collects and manages information from the FrontEnd,Mediation, and other server roles Stores the information in a database that is separate from the oneused by the front end Uses SQL Server Reporting Services to create reports related to callquality and metrics A single monitoring server can monitor several pools of front end 20. Configurazione del ruolo MonitoringOnce the report pack for SQL Server Reporting Services is installed, we can proceed to using theLync Server 2010 Control Panel to configure monitoring for the Lync environmentUser experience which provides qualitative Test the reports via:By default, there is only one global policy and quantitative analysis of every callhttp://serverFQDN/Reports 21.

Add: Conferencing Components 24. Conferencing Infrastructure 25. Audio e Dial-In Conferencing Lync Server 2010 has dial-in conferencing support on top of an existingvoice infrastructure where IP/PSTN gateways are in place and functional An organization can continue to leverage its existing phone handsets andPBX while still using the rich dial-in conferencing meeting and schedulingexperience This enables organizations to begin using the audio conferencing servicewithout a significant investment or change to user behavior Users can continue to use their current handsets, but gain the capability toschedule and join meetings using a Lync client 26. Lync Autodial Users that are already authenticated to Active Directory through theLync client do not need to manually dial the access number andenter an extension and PIN Lync can even dial the users work number automatically 27. DEMO : Deploy di uno Standalone Conferencing ServerMain Switchroom,Central TelephoneExchange, WillsStreet 1908 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 internalinfrastructure Federation with partner organizations or public IM providers Deploy both in a standalone scenario and in a high-availabilitydeployment where multiple Edge Servers are used Reverse proxy server is required 30. Edge ServicesThe Edge Server comprises three separate subroles : Access Edge Server Web Conferencing Edge Server A/V Edge ServerEach role provides different functionalityIt might not be necessary to use all three servicesNo database / file sharesLimited set of services to make it as secure as possibleEdge 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 filetransfer 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 servicesthat dont run through an Edge Server. The reverse proxy provides remote access to the web componentsrunning 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 anddial-in conferencing The Mediation server translates signaling between your internalLync Server 2010 infrastructure and an IP-PBX gateway or IP-PSTNgateway, or a SIP trunk Mapping with multiple gateways The flow of media can also be configured to bypass the Mediationserver 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 audioand 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, higherbandwidth 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 isgenerated for all network sitesIf the bypass IDs do notmatch, media for thecall flows through the If the two bypass IDsMediation server at the If the two bypass match, Media Bypass is central siteIDs match, media used for the call When a user makes aflows directly from When a user PSTN call, the the gateway to the Mediation serverreceives a call fromclient, bypassing the compares the bypass the PSTN, the users ID of the client subnetMediation server client compares its with the bypass ID of the gateway subnetbypass 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 PSTNgateway 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 areanetwork (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 andMediation server software installed It is designed for branch sites that host between 1,000 and 5,000 users who lack a resilientWAN 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 telephoneservice provider 40. SBA Servizi Disponibili e Non DisponibiliThe following services are available in the event ofPSTN and other voice servicesunavailable in a WAN outage: The following services areHold, retrieve, transfer IM/V/W conferencing Authentication and authorizationa WAN outage: PresenceCall forward, simul-ring, boss-adminCall detail recordsUpdate call forwarding setting Intrasite IM and A/VResponse group service PSTN audio conferencing 41. Enterprise Voice Enterprise Voice is Microsofts software powered Voice overInternet Protocol (VoIP) solution Because VoIP sessions can traverse network address translations(NATs) and firewalls, users working at home or traveling can use theInternet to communicate with coworker This creates the opportunity to prevent incurring long-distancecharges without the use of a virtual private network (VPN) 42. Voice RoutingDial Plan A dial plan contains a set of normalization rules to convert dial strings to a routable format and is assigned tousersNormalization Rules Associated with a dial plan and converts the digits a user might dial into a common format that is then routableby the systemVoice PoliciesDetermines what voice features users are allowed to useRoutesAre used in Lync Server to direct calls through a specified gateway or a set of gatewaysPSTN Usages Usages are a class of call that is then associated with voice policiesGatewaysAny object that Lync Server sends calls to can be considered a gatewayTrunk Configuration A logical connection representing the connection between Lync and a PSTN gateway, IP-PBX, or InternetTelephony 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 extensionCall Park Direct calls to unassigned numbers to an attendant or operatorUnassignedNumbersAdministrators 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 bandwidthCall AdmissionControlMedia Bypass Enhanced 911 provides the callers telephone number and street address to a dispatcher automaticallyThis is an advantage overEnhanced 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 serviceResponse GroupService 44.
