Nouveautés de Microsoft Communications Server 14

Summary:

  • The live meeting conferencing functionality will be rolled into Communicator “14″.  There will be one client, Communicator, for all media modalities and the associated features.
  • There will be a new Silverlight-based web client available for those users wanting to joing a web conference, but don’t have the rich Communicator client installed.  This is a new client and not a replacement for Communicator Web Access.
    • When a user clicks to join a meeting from a link, it detects whether the Communicator client is installed. If it is not, you can join via the Silverlight client.
    • Participation via the Silverlight client is anonymous (i.e there is no sign-in required).  This is a powerfull feature that will make it a whole lot easier for external (to your organization) attendees join a meeting.
  • MCS 14 will federate with Windows Live “Wave 4″ and will support Audio and Video with Windows Live Messenger contacts.
  • All MCS 14 features were designed ground-up to work on-premise, cloud, or hybrid:
    • both in terms of supporting a percentage of MCS users on-premise, in the cloud, and,
    • in terms of having some or all Exchange & SharePoint services in the cloud
  • Supported virtualization for all server roles in MCS 14 (with the normal audio and video caveats;  i.e. you must closely follow the virtualization guidelines to support audio and video, and even then it could be more suceptible to jitter and latency)
  • The MCS 14 will support a media bypass feature which will allow a consolidated MCS “14″ front-end server to go direct SIP to a supported IP-PBX’s without having to through a mediation server when the call is going to a locally dialed PSTN number.
    • the Media by-pass, coupled with the branch office survivability will remove the need for Mediation servers in most local or branch sites (in most cases)
  • Multiple SIP Gateways can be connected to one Mediation server.
  • Communicator “14″ will support the G.711 codec and will be able to talk to certified MCS “14″ media Gateways to go out local PSTN access points.
  • The visual Presence circle is changing to a square in Communicator “14″!  :-)

Office Communicator “14″

Management

  • A new Silverlight web-based management console (Communication Server Control Panel) that is built on a new set of Communications Server PowerShell cmdlets.
    • Support for Role Based Access Control administration (similar to Exchange 2010)
    • Support for cut-and-paste in the UI (i.e. easily copy Normalization Rules)
    • Can easily see all the Policies (i.e. Voice, Conferencing, Client) for a particular user in one place
  • A new Central Management Store (CMS)
    • a central database the holds XML documents that describe your deployment
    • all topology changes get written to the CMS, and a read-only copy is pushed to all servers in the topology
    • the topology is pushed out via a file transfer agent and via HTTPS for the the Edge role
  • New tools to help with certificates!
  • New support for ’server maintenance’ – a server can be put into maintenance mode for O/S and hardware maintenance
  • New PowerShell cmdlet’s
    • Everything in the new UI can be done through PowerShell
    • Cmdlets to manage users, configuration, devices, policies
    • Support for synthetic transactions (test phone calls, sip registrations, simple conferencing)

Topology Changes

  • More support for role collocation.  More roles, including the Mediation role and CWA, can be installed with the Front-End
  • A new “Site” topology entity which can be used to represent a geographic boundary such as a center or branch location.  A site contains one or more pools
  • Similar roles as OCS 2007 R2 (i.e. a backend role that defines a pool, Edge Mediation, AV Conferencing, Archiving, Monitoring, Director, Group Chat)
  • The Director role now streamlined and includes a local SQL Express database – removing the need for a separate back-end SQL database.
  • The concept of Standard and Enterprise edition still exists
  • Support for DNS load balancing within a pool
  • New Topology Builder UI which helps you build your topology document

Virtualization

  • Support for the virtualization of almost all roles
  • Client virtualization support is similar to Communicator 2007 R2 (i.e. IM and application sharing but audio/video is not supported)
  • Cannot virtualize the new branch office workload

Monitoring

  • New SCOM 2007 R2 management pack:
    • Support for synthetic transactions (monitor the user experience)
    • Media quality alerts
    • Call failure alerts
    • Actionable alerts
  • Monitoring role can be collocated with the front-end role
  • The ability to ‘heal’ the audio of a particular end-point if the Monitoring role detects degradation in quality.
