Database Clustering

Highlights

Odd number of DB servers required for reliable master election if network split

DB nodes needs to see more than half of the cluster members to be eligible as master

Max 5 DB server, recommended 3

All DB operations are directed to the master

Separate DB server improves CallBridge robustness and simplifies upgrades(suggested with server with distribute processing (cms2000, X3) and large DBbs (>10k spaces))

Max of 8 Call Bridges per cluster.

Designs more than 8 Call Bridges in a cluster need to be validated by Cisco BU

XMPP Clustering

Highlights

XMPP High Availability mechanism with keepalives

3 or 5 XMPP Servers

Master election similar to the database cluster

Call Bridges gets XMPP server list from DNS _xmpp-component._tcp SRV record

(use GEO DNS to optimize geographically the XMPP server selection)

Call Bridge must be configured on all XMPP servers with same credentials(use the xmpp callbridge add once and then xmpp callbridge add-secret)

All XMPP traffic is forwarded to XMPP master (CallBridge/loadbalacers can send message to any XMPP server)

Full mesh connectivity from LoadBalancers to XMPP servers is not required

Max 500 sessions per XMPP cluster

Max 200 msec RTT between XMPP servers

Deployment Prerequisites - DNS• Several DNS records are required for the solution to work properly

• The main DNS records are:

1. 1) DNS A records for all the servers involved (e.g. cms1-us.mycompany.com)

2. 2) DNS A records for user access to services (e.g. meet.mycompany.com)

3. 3) DNS SRV records to locate XMPP server:

4. -For clients and internal services _xmpp-client._tcp.mycompany.com port 5222-For CallBridges to locate XMPP cluster members _xmpp-components._tcp.mycompany.com port 5223

5. A more comprehensive list is in installation docs

• Large conference design involves (discussed in the Edge section)

• GEO DNS for optimal allocation of service entry point from Internet

• Split DNS allocation of external, internal service

Deployment Prerequisites - Certificates

Components that need a certificate:

•WebAdmin

•XMPP

•WebBridge

•Callbridge

•Loadbalancer

•Trunk

•Turn (if using TLS)

•Database Cluster

•Recording server

•Streaming server

Certificate types:

• self-signed

• Private CA Signed

• Public CA Signed

Reduce Certificate Complexity

• Plan/design certificate structure before deployment

• Combined Certificates

• Certificates shared among multiple components and servers

• Use multiple FQDN entries in certificates Subject Alternative Name (SAN)

• CA-Signed

• Combined certificates have some limitations:• database clustering (client) needs separate certificate

• Lync/S4B integration have specific requirements

• Wildcard certificates

• Supported but limitations applies too

Call Bridge Group - Feature I: Grouping

• CMS 2.1 introduces the concept of CallBridge Group

• When CallBridges in the same region or DC are placed in the same CallBridge Group, conference will not be distributed between them

• It leverages the SIP replace mechanism (supported by CUCM)

• When CUCM makes a call to a conference (space) in a CallBridge, if the conference exists on another CallBridge in the same group, then the call is “replaced” to the correct call Bridge

• Network Requirement : Max latency between members of a Call Bridge Group 100 ms RTT

Call Bridge Group – Feature II: Load Balance• A mechanism is necessary to ensure load

balancing of conferences in the same CallBridge Group

• This is implemented by distributing conferences based on conference_ID and bridge_ID hashing that generate a “priority” in the CallBridge choice

• It is totally transparent to the user and it leverages the same replace mechanismfor call reallocation

• Load balancing is applied from the first call to a space

Call Bridge Group - Feature III: LoadLimit

• Before version 2.1 the CMS carried on accepting calls even when it was “full” by simply reducing other call resolution to accommodate load

• With 2.1 a max load Limit can be configured on each CallBridge so that when a call is received and the CMS is above a limit CMS rejects the call;

• Limit is variable according to the conference state

• CUCM receives “SIP 488 ,Not acceptable here”, and Dial Plan (RG, RL) can be configured to route advance to next call bridge

• Because of this, one SIP trunk per CMS is required,so that error handling “surface” to CUCM RG/RL level

Max load Limit 100%

Existing Conference Threshold 80 %

CMS Dial plan : Inbound call processing

Stage 1 Incoming

• Is the call for this CMS ?

• For spaces, users, IVR ?

• Does the call require a Lync meeting resolution ?

Stage 2 Forwarding

• Shall the call be forwarded ?

• With domain rewrite ?

Stage 3 Outgoing

• Where to send the call ?

• And how ?

In use case 1:

CUCM SIP domain ucdomain.com

CMS cluster SIP domain meet.ucdomain.com

Use Case 2

A large traditional worldwide enterprise where employers meeting are mediated by

white gloves service from an internal video service team

Structural requirements (*): Conferencing requirements:

• Three worldwide regions

• Redundancy with 2 DC in each region (**)

• Traffic Optimization

The great majority of the video conferences are

• Scheduled and managed by the video team

• Connected automatically (auto-connect)

42BRKCOL-3990

(*) Structural requirements will be the same in most of the use cases presented

(**) More regions or more DCs can be added to the same design

Key challenges with scheduling with white glove services

• Challenge 1: Optimal call routing with auto-connect

• Solution:• If video endpoints belong to different regional SIP domains,

then a single worldwide CMS cluster can still be used and call routing optimized - TMS 15.5+ and CMS 2.2+ to enable loadBalanceOutgoingCalls in CallBridgeGroup- configure per region CallBridgeGroup specific outbound dial rules

• If video endpoints belong to same SIP domain, then a separate regional CMS clusters can be deployed

• Challenge 2 : TMS Conference Control Center (CCC ) does not support CMS

• Solution : • Cisco Meeting Manager (CMM)

CMS WebProxy feature in Expressway

• First step toward the single edge

• CMS WebProxy feature in Expressway leverages expressway existing capabilities (TURN and MRA Web-Proxy) to facilitate firewall transversal of WebRTC CMS clients

• On expressway it can coexist with MRA, B2B, Registrar, IMP federation but not with Jabber-Guest or Expressway-MS Interop

LIMITATIONS

• CMA native clients still needs classical CMS edge

• TURN on TCP port 443Planned for Expressway X8.11

• Load balancing is supported, but no redundancy

• Expressway TURN for native/CMA clients is not yet supported

CMS Edge Design - Sizing

• TURN server allocation limits:

• CMS TURN server: max 1000 allocations

• Medium Expressway: max 1800 TURN allocations

• Large Expressway: max 6000 TURN allocations (*)

• Notes :

• Each CallBridge will use only one TURN server of a certain type (standard or Lync)

• TURN allocation are requested for every CMA, WebRTC and distributed calls (not on standard SIP calls), TURN allocations are kept for the call duration (as safeguard for network connectivity problems)

• With audio, video and content streams, each with media and control, 6 allocation are needed per TURN client, so we can size 6 TURN allocations for internal calls, 12 TURN allocation for calls over internet (CMA or WebRTC)

(*) 6000 TURN allocation using one port are planned for new expressway release

CMS Edge Design – Service Selection

• A combination of factors influence edge service selection and hence high availability and traffic localization:

• DNS resolutions

• RTT calculation

• Configuration

• Notes• RTT has an important role so administrators have not full control on traffic localization

• CallBridge Groups feature at edge is not a complete solution but it helps in cleaning up the selection process by “reducing the number of choices” (e.g. excluding choice like CallBridge in EMEA via TURN in APAC)

• When more granular control is required, explicit selection of CallBridgecan be used in alternative to CBGroup (e.g. TURN in DC1 in US is bound to CB in the same DC)

Next slides detail the mechanism and how they can be used for High Availability and Traffic localization

Load-balancing of CMA native and WebRTC calls New in CMS 2.3, this complements the load-balance feature suite

• The same mechanism to avoid distributed call inside a CallBridgeGroup is available for client calls CMA and WebRTC on CMS 2.3

• Inside a CallBridgeGroup, CMA calls to the same meeting will not be distributed and they will happen on one CallBridge (as long as it has capacity left)

• Configuration steps:1. Add a CallBridgeGroup and place the CallBridge in the group

2. In the CallBridgeGroup configure (with API) loadBalanceUserCalls(in addition to loadBalancingEnabled for SIP call load balance)

3. Ensure that each Call Bridge in the Call Bridge Group has a connection to the XMPP cluster or single XMPP server

• Log messages are similar to a normal “load-balanced” call

Points of attention and limitations

Expressway do not support yet load balance with CMS (callBridgeGroup)

Hair-pinning traffic to CMS from Expressway require a relatively complex dial plan

Because of that for large deployments, it is simpler to have one separate “adaptation” CMS

per region – separate from the interregional MS cluster

O365 OBTP Dual Homed experience

• Office 365 users join skype meeting (o365 cloud same organization)from Video Endpoints with OBTP and with Dual Homed Experience

• Prerequisites: CMS 2.2, TMS 15.5, TMSXE 5.5, X8.10.2+

• Operation (see next slide) :• TMSXE monitors the room mailboxes

• When it sees a meeting it gets the skype alphanumeric URL value fetched from MAPI property

• TMSXE appends the cisco meeting server domain name (a sort of dummy/routing domain)

• TMS saves the appointment in TMS as “Externally Hosted” conference(no resource local reserved)

• When meeting start and OBTP is pressed, CMS resolves the Lync Simple Meet URL(requires both connectivity to internet and permission to resolve)

• Then CMS sends an INVITE to join the resolved meeting

• Minimal number of port opened on internal firewall

• Avoid traffic between DMZs in different DCs(caused by HMN inter-cluster signalling and media)

HMN placed in DMZ

• Security policies may prefer this: the “extension of the cloud” devices is confined to DMZ

Design Notes

CUCM SIP trunk(s) to HMN

• Cloud allocates HMN within cluster (CUCM is informed by SDP)

=> HMNs in same cluster can be assigned to same CUCM SIP trunk(One trunk with multiple HMN IPs for each HMN cluster)

• CUCM Route Groups/Lists are needed for

1. Traffic overflow via Expressway (route advance on SIP error 488)

2. Routing to multiple HMN clusters

Additional Design Notes

CUCM SIP trunk(s) to HMN

• CUCM trunks to different HMN regional clusters need be separate

HMN traffic

• HMN intra-cluster traffic stays within enterprise network

• HMN inter-cluster traffic use cloud

HMN selection (SIP devices)

• HMN cluster used for the call is chosen by CUCM

• HMN server inside a cluster is chosen by the cloud based on HMN inputs (latency, load)

HMN selection (Spark clients/rooms)

• HMN is chosen by cloud based on reachability info provided by client (STUN RTT) with preference for on-premises HMN

Additional Design Notes

Want to keep media on-premises

• Do not close port 5004, this will cause split meetings !!

• Traffic via cloud can be reduced but not avoided, the following traffic types go anyway via cloud

• Spark/HMN signaling

• Webex signalling and media

• HMN Inter-cluster signalling and media

Approach to limit HMN inter-cluster traffic for SIP devices: CUCM Time Of Day Routing

1. Prefer a regional HMN cluster at a certain time of the day,

2. with alternate route to the other HMN regional clusters for High Availability and Overflow

3. and to cloud via Expressway for overflow

• TOD time switch should avoid meeting start time :00, :30 (:45 may be a good choice)

Limitations

• Spark clients and rooms (not covered by this use case) do not follow CUCM allocation.

• Strategy applies only to dial in to Webex/HMN Future HMN dial out feature may not fit this approach

LDAP integration : things to watch

• AD mapping creates 3 dial-able URIs in CMS : Primary and Secondary Space URI and User URI

=> None of them should overlap with other URI in the network

• Dual mapping with alphanumeric and numeric URI for spaces provides a flexible way to join spaces

• Sizing : If more than 30000 users need to be imported from AD, the design should be validated by Cisco

• There is a lot of flexibility in configuring LDAP• Multiple LDAP sources and mapping can be configured

• LDAP configuration on CallBridge is per server when configured using GUI

• All CallBridges in a cluster can update users and space database

• For a clustered environment, it is best to configure LDAP integration using API

But case should be take to to avoid feeding CMS with incongruent information

CMS 2.2 – Load balancing of outbound SIP calls

Operation:

• When CMS receive an API request to make an outbound call, it finds the highest priority outbound dial plan rule that matches the SIP domain,

• if this applies to a local Call Bridge, then balance the call within the local Call Bridge Group.

• if this only applies to remote Call Bridges, then load balance the call within the Call Bridge Group to which the Call Bridge is a member

As a consequence, traffic can be optimized as long as video endpoints belong to different regional SIP domains
