Agenda

  • What is Lync Server?
    • History
    • Industry recognition
  • Implementation approaches
  • Technical differentiators from Office Communications Server (OCS)
    • Setup and deployment
    • Introducing:
      • The Central Management Store (CMS)
      • Call Admission Control (CAC)
      • Media Bypass
  • Futures
slide5

What is Lync Server?

  • Lync not LINQ
  • The new name for OCS
  • An IP-PBX or traditional PBX replacement
  • A new breed of software-based telephony
  • Fully immersed within your PC (or Mac) desktop user experience – Office, SharePoint & Lync Client
  • The heart of Microsoft’s UC stack

Then…

Microsoft®

Office Communications

Server

  • A PBX companion – high level deliverables include:
  • Voice calls via existing handsets (RCC) and Communicator/“Optimised Devices” (EV)
  • Video calls
  • IM and presence
  • Mobility (including IM, presence and single-number reach)
  • Collaboration (desktop/file sharing, group chat and *dial-in conferencing)

*Office Communications 2007 R2

slide8

And now…

Microsoft

®

Lync

TM

  • A PBX replacement – via added functionality:
  • Enhanced resilience - without the need for h/w load balancing (web workloads still require HLBs)
  • Survivable Branch Appliance – a purpose-built appliance for branch deployments
  • Call Admission Control (CAC) – for the prevention of VoIP over subscription
  • Enhanced 9-1-1 (NA only) – CU1 delivers location functionality
  • Superior conferencing - voice announcements and an integrated client! (no Live Meeting client or Outlook Conferencing add-in)
slide9

Industry recognition

“OCS…is certainly going to shake up the market.”

36% companies surveyed are already using OCS as UC client, more than IBM, Cisco and Public IM clients.

“If you didn’t think Microsoft was serious about voice communications before, you better believe it now.”

“Magic Quadrant for Unified Communications,” July 28, 2010.

slide10

Implementation approaches

Identify PBX integration opportunities – software upgrades and/or a vendor application gateway. Consult your PBX vendor and visit the *UCOIP

Introduce Conferencing functionality and cut existing costs (measure telephony capacity first) – my workplace saved £60k per annum!

Leverage existing PBX investment and introduce Communicator concepts via RCC

Consult your PBX vendor and visit the *UCOIP, identify integration opportunities. Alternatively you can deploy a side-by-side voice gateway

Telephony growth supported by EV with Lync chosen as standard for strategic replacement

Initially choose mix legacy, RCC and EV for agile workers (project teams, senior executives and IT)

Alternatively it could be the right time to replace your existing PBX for Lync – how many times has this asset been written off? 

For greenfield deployments a voice gateway could be used, consult the *UCOIP for supported hardware

*Unified Communications Open Interoperability Program - here

slide12

Key Lync Roles and Servers

  • *Central Management Store (CMS)
  • covered in subsequent slide

Back End Server

Lync database

Archiving Server

collects IM and Meeting content

Monitoring Server

collects call quality and CDR related information

Director

Internally, routes clients to corresponding home server

Externally, reverse proxies authentication requests

Front End Server

Handles authentication/registration, address book, IM, Conferencing & Response Groups

Mediation Server

translates signalling and media (where bypass is not used) and routes to PSTN via gateway, IP-PBX or SIP trunk

Edge Server

used for external Communication & Collaboration (without the need for VPN)

*Survivable Branch Appliance (SBA)

a purpose-built Lync appliance, typically utilised for branch deployment

A/V Conferencing Server

as the name suggests (can be collocated with Front End server or deployed separately)

*Introduced with Lync

slide13

Setup and deployment changes worth mentioning

  • Planning Tool
    • Export to Topology Builder (.tbxml)
  • Topology Builder
    • Tool used for .tbxml import, topology setup, modification and validation prior to deploying first server and publishing within the Central Management Store (CMS)
  • Mediation role can now be collocated with front end role = minus 1 server
  • Essentially one Standard Edition Server could support Enterprise Voice, IM, Presence and Conferencing for up to 5000 users!
  • For more information on planning and designing your Lync topology, I’d suggest you watch Lync Server Planning Tool: Design a Site and Create a Topology via TechNet NextHop (see resources slide)
slide14

Central Management Store (CMS)

  • Replaces Active Directory for most configuration storage (phone numbers still held within AD)
  • The CMS data is held within a SQL database
  • Centralises the administration of all Lync Server roles (including Edge servers)
  • There is a minimum requirement of 2 x CMS databases - 1 x master (RTC) and 1 x replica (RTCLOCAL)
  • RTC and RTCLOCAL databases are replicated
  • Resilient architecture – Front End Server CMS (replica) will continue to function where connectivity is lost to the master
slide15

Call Admission Control (CAC)

  • Put simply CAC is the bandwidth management service built into Lync Server
  • CAC bandwidth policies can be set to control
    • Audio - max bandwidth (kbps) assigned for all/individual sessions
    • Video - max bandwidth (kbps) assigned for all/individual sessions
  • Policies are applied between sites, where multiple network subnets can be associated
  • Alternate routes can be utilised where over-subscription occurs, i.e. when local ISDN is at capacity then a route to PSTN over an Internet based SIP trunk could apply
slide16

Media Bypass

  • Media bypass reduces the load on your Mediation servers (allowing support for up to 5000 users, where Front End and Mediation roles are collocated)
  • This is achieved by negating the need for transcoding between the Lync client or phone and the voice gateway
  • In this scenario the G.711 voice codec is used, instead of RTAudio
  • Recommended gateway vendors include AudioCodes, Dialogic, NET and Ferrari
slide18

Lync Mobile

  • Mobile clients are expected for:
    • *iPhone aka “iLync”
    • *Windows Phone 7
    • BlackBerry – now available BES v.5.0 SP3
    • Nokia
    • Android
  • *NB
  • Functionality will include:
    • One-click to join conference
    • Single number reach
  • ETA late 2011

Lync Server + Skype = ?
