3 Multisite Distributed Deployment Options Multisite Distributed Deployment Options The site models within each test group (North America and EUEM) can be implemented in various combinations to create deployment models to meet the needs of a wide range or organizations. For detailed information about the sites used in North America deployments, see the North America Site Models. For detailed information about the sites used in EUEM IP telephony deployment, see the Europe and Emerging Markets Site Models. The Solution integration test bed topologies diagrams for NA and EUEM for IP telephony tested in Cisco Unified Communications Release 8.5(1) is available from the Resource Library tab of the Technical Information Site. North America Site Models Eleven site models were created and tested for Cisco Unified Communications Release 8.5(1) testing for North America IP telephony. Each site model tested specific hardware and software components, features, functions, protocols, and related items. A site model includes one or more sites. Each site has a three-letter name (for example, SFO, ORD, and SJC). Examples throughout this manual refer to these site names. The following sections describe each site model in detail. Each section includes an explanation of the design characteristics of the site model, and includes a table that lists the hardware and software components used in the model. The tables contain the following information for each component: Component Hardware or software component Description Information such model number5 release number, protocol, and hardware platform Qty. Quantity of the component used in the model Table 1 lists the site models and references to sections that provide detailed information.

In this model, half of the cluster resides in SFO and the other half in ORD. These sites provide centralized call processing to remote Cisco Unified Survivable Remote Site Telephony (Unified SRST) sites. Communications with remote sites takes place over the IP WAN. If either the central site or the IP WAN goes down, remote sites can continue to have service through Unified SRST running on Cisco IOS gateways. In addition, remote sites can place calls over the PSTN if the IP WAN becomes temporarily oversubscribed. The cluster is also enabled for IPv6. SCCP endpoints have been added in both the SFO and ORD Head Quarter locations to exercise IPv6-based calls. Additionally, the ORD datacenter is now completely on Cisco Unified Computing System (UCS). This includes the CUCM and Unity Connection nodes. SFO and ORD sites represent geographically redundant data centers and are the hub sites for remote Unified SRST sites. Unified SRST sites include H.323 and MGCP 28xx, 29xx, 38xx, 39xx, and 72xx gateways. The WAN consists of T1 frame relay links. The tested Multisite Centralized site model has the following design characteristics: Cisco Unified Communications Manager and Cisco Unity Connection reside at the central site Cisco Unified Communications Manager clustered over the WAN Centralized dial plan and administration 100 remote sites Unified SRST for remote sites 17,840 SCCP endpoints Figure 1 provides an overview of the Multisite Centralized, Clustering over the WAN with Unified SRST site model. 4

18 North America Site Models Tested Deployments and Site Models Cisco Unified Communications Manager - Session Manager Edition Site The Cisco Unified Communications Manager - Session Manager Edition site model contains two sites, Kansas City (MCI) and Los Angeles (LAX), designed to simulate Session Management Edition of the Unified Communications 8.5 system train. This cluster includes: One publisher and one subscriber (MCI) Two subscribers (LAX) This deployment model has the following charcteristics: Mix platform with MCS & UCS: MCI site has IBM MCS servers, and LAX site has one IBM MCS server, and one UCS B-series based virtual server. Distributed call processing deployment model with Clustering over the IP WAN configuration. All non-saf ICT SIP and H323 (Non GK) trunks configured on SME use Call routing enhancement option to run SIP trunks on every subscriber node in the cluster. All SIP trunks configured on SME cluster use SIP option PING to track the status of the configured destination of SIP trunks and only send SIP messages to reachable remote peers. SIP Early Offer Enhancement option is enabled on selected SIP trunks in SME and on leaf clusters. End-to-end (E2E) RSVP CAC: in SME test bed topology, there is only signaling traffic, no media traffic between SME and leaf clusters. All calls coming in from the leaf clusters and going out to the leaf clusters are not subjected to the location CAC in SME. RSVP agents on leaf clusters represent locations between leaf clusters, and are subjected to the RSVP Call Admission Control. Calls between SJC and DFW leaf clusters perform e2ersvp CAC. The Service Advertisement Framework (SAF) deployed in the test bed, coexists with the SME cluster and enables leaf nodes to discover automatically other network services run on other leaf nodes through centralized SME cluster. Cisco Unified Border Element Scalability and Load Balancing: Cisco Unified SIP Proxy is used to provide a central route point for management of pair of Cisco Unified Border Elements, MCI-CUBE-1 & MCI-CUBE-2 in MCI side and LAX-CUBE-1 and LAX-CUBE-2 in LAX side of SME cluster. In CUSP, load balancing and rule-based routing is applied for ingress and egress traffic. Each pair of the CUBE uses same configuration. If a CUBE is unavailable, CUSP can intelligently reroute to an alternate CUBE. When the CUBE returns to service, CUSP resumes sending traffic to the CUBE.

21 Europe and Emerging Markets Site Models Large Multisite Centralized with Unified SRST The Large Multisite Centralized with Unified SRST site model consists of one site called Paris (CDG). This site model represents an international deployment with up to 21 remote sites deployed across various countries. It includes Cisco Unity Connection and third-party components. Cisco Unified Communications Manager uses QSIG, H.323, and SIP to interoperate between sites. Remote sites are interconnected through the WAN and all are RSVP-enabled to the central site. For Geneva (GVA) and Paris (CDG), inter cluster RSVP is enabled. In this model, a Cisco Unified Communications Manager cluster serves 6000 phone in local and remote locations, with all endpoints and gateways fully encrypted (RTP and signalling). PBXs that support the QSIG ISO and QSIG ECMA variants connect to this cluster through direct QSIG links. The Cluster connects to the rest of the network through MPLS WAN networks. Calls between the CDG site, the LGW site, and the MAD site are provided by H.323 intercluster trunks. Cisco Unity Connection provides voice messaging. PBX users access voice messaging features through the QSIG trunks to Cisco Unified Communications Manager. Access to the PSTN for normal off-net calls is provided by ten E1 ETSI PRI links to the PSTN. Remote sites have either centralized breakout to the PSTN or local PSTN breakout using E1 PRI, BRI, or FXO connections. PSTN access is controlled by Cisco Unified Communications Manager using MGCP, H.323, or SIP. Unified SRST is used in each remote site. Access to the SIP network is provided through a SIP trunk to a remote Cisco Unified SIP Proxy (CUSP). Access to third-party services such as operator console, if available, is provided locally. Some of the sites will also have video endpoints and Cisco Unified Videoconferencing Gateways, and remote QSIG PBXs. Cisco Unified Communications Integration for Microsoft Office Communicator and Cisco Unified Presence Server are tested as part of this site model. Cisco Unified Communications Integration for Microsoft Office Communicator provides interoperability with Microsoft Office Communicator Server 2007 (OCS) R2 version with Microsoft Office Communicator (MOC) clients.

In the EUEM sites, the Unified CM Session Management Edtion deployments consists of two sites: Paris (CDG-SME) and Geneva (GVA-SME). In this deployment there are two Unified CM-SME clusters namely CDG-SME cluster and GVA-SME cluster, CDG-SME cluster is co-located with CDG site and aggregates trunks (SIP, H.323, QSIG, and QSIG over SIP) from the CDG leaf node, MAD eaf node and LGW leaf node. The GVA-SME cluster is co-located with GVA site and aggregates trunks (SIP, H.323, QSIG, and QSIG over SIP) from the GVA leaf node, RKV leaf node and Brussels leaf node. CDG-SME cluster and its leaf nodes (CDG, CDG-remotes, MAD) are running in the SAF Autonomous system 333 and GVA-SME cluster and its leaf nodes (GVA, RKV, Brussels) are running in the SAF Autonomous system 444, at present we have NOT enabled static re-distribution between the two SAF ASs. 27

28 Europe and Emerging Markets Site Models Tested Deployments and Site Models Paris (CDG-SME) site Geneva (GVA-SME) site Cisco Unity Connection server provides voice mail services to Unified CM, Unified CM-SME, and remote users. Service Advertisement Framework (SAF) and Session Management Edition (SME) Setup: SAF allows networking applications to discover the existence, location, and configuration of networked services (Call Control Discovery) within networks by using the underlying network as a transport for service advertisements Cisco Unified CM Session Management Edition: CUCM-SME is essentially a Unified CM clusters supporting a large number of trunk interfaces and enables the aggregation of multiple UC systems using multiple trunk types for voice, video and fax calls The focus of SAF testing for Fairborn release is centered on combining the CUCM-SME (Centralized Architecture) and SAF (Distributed Architecture) The CDG-SME cluster consists of CDG leaf cluster (Unified CM servers), Cisco Unity Connection server, Gateways and Gatekeepers. The CDG-SME cluster is connected to MAD leaf cluster through a QSIG SIP trunk and to the LGW leaf cluster through H.323 Annex M1 trunks. There are two QSIG SIP trunks configured between CGD leaf and CDG-SME cluster and also between CDG-SME and MAD leaf cluster. One of the SIP trunks is a SAF enabled SIP trunk and the other is a static SIP trunk. When a call is made from CDG (leaf) to MAD (leaf) via CDG-SME cluster, first leg from CDG (leaf) to CDG-SME cluster will be SAF trunk and second leg from CDG-SME cluster to MAD (leaf) will be static SIP (QSIG) trunk. The CDG-SME cluster Site model has these design characteristics: CDG Leaf cluster (Unified Communicatons Manager servers) CDG-SME cluster (Unified Communicatons Manager Session Management Edition servers) Cisco Unity Connection for voic Gateways (Cisco Unified Border Element, Cisco 3545 MCU) and Gatekeepers (Cisco 3845) Static QSIG SIP trunk between CDG leaf and CDG-SME cluster SAP enabled QSIG SIP trunk between CDG leaf and CDG-SME cluster Static QSIG SIP trunk and SAP enabled QSIG SIP trunk between CDG-SME and MAD leaf cluster H.323 Annex M1 trunk between CDG-SME cluster and LGW leaf The GVA-SME cluster consists of GVA leaf cluster (Unified CM servers), Cisco Unity Connection server, Gateways and Gatekeepers. The GVA-SME cluster is connected to RKV leaf through SAF enablaed SIP trunks and to the BRU leaf through both statis SIP trunk and SAF enabled SIP trunk. The GVA-SME cluster Site model has these design characteristics: GVA Leaf cluster (Unified Communicatons Manager servers) GVA-SME cluster (Unified Communicatons Manager Session Management Edition servers) Cisco Unity Connection for voic Gateways (Cisco Unified Border Element) and Gatekeepers (Cisco 3845) Static QSIG SIP trunk between GVA leaf and GVA-SME cluster SAP enabled QSIG SIP trunk between GVA leaf and GVA-SME cluster 28

In this model, two servers Cisco Unified Communications Manager Linux based Unified CM clusters serve 1000 phone users in both local and remote locations. A separate Cisco Network Registrar (CNR) server is used to provide DHCP IPv4/IPv6 addressing for the central site. It also acts as the DNS IPv6 and IPv4 for both the central and remote sites. This cluster is connected to the rest of the network through MPLS WAN networks. Calls between this site and other sites (LGW and MAD) sites are made through the WAN with Annex M1 Inter Cluster Trunks. All the internal calls within the site are G.711 and all calls between sites are G.729. Cisco Unity Connection server provides voice mail services to both Unified CM and remote users. Access to the PSTN for normal off-net calls is provided by E1 ETSI PRI links to the PSTN. 30

31 Europe and Emerging Markets Site Models The three remote sites are connected through a WAN link and they have location based CAC to the central site. PSTN access for these remote sites either have centralized breakout to the PSTN, or local PSTN breakout using E1 PRI, BRI, or FXO connections and are controlled by Unified CM using either MGCP, H.323, or SIP. Unified SRST is used in each remote site. Some of the phones have security encryption. VG224 acts as dual-stack gateways and Cisco 2851 acts as analog SCCP gateway. The LAN infrastructure of this site includes CAT4500 as distribution/core switch and Cisco 3750 and Cisco 3560 as access switches and both of them are dual-stack components. The MTP component provides media stream conversion from IPv4 to IPv6 and vice versa. The CE router and the MTP component share the same hardware Cisco The CE router and the remote ISRs provides IPv6 to IPv4 tunneling over the WAN. One of the SRST remote has been enabled with HSRPv6 (active-active) and DHCPv6.
