6 C1640M-B (3/06) ENDURA COMPONENTS Endura components take full advantage of leading edge technologies such as Universal Plug and Play (UPnP ™ ), allowing for fast, error -proof installations and set up. Essentially , when an Endura device is added to a system, it announces itself and the services it has available.
C1640M-B (3/06) 7 Network Architecture The Endura network topology is based on using current networking technology . Pelco suggests that you recommend or select networking devices and technologies that meet or exceed the features and functionality described in this section.
8 C1640M-B (3/06) – Sparse Mode is most useful in the following instances: • There are few receivers in a group. Switches send multicast traffic only to the devices that request it. • Senders and receivers are separated by Local Area Network (LAN) links.
C1640M-B (3/06) 9 Understanding the Endura Network Structure The primary structure of an Endura network topology is organized into functional entities, which are called “blocks.” Grouping the functional entities into individual blocks provide the following benefits: • Blocks control and isolate traffic.
10 C1640M-B (3/06) ENDURA A BLOCK The A Block is the most important design entity of the network. The A Block is functionally responsible for encoding, recording, and storage of the video streams entering the Endura network (both live and playback video).
C1640M-B (3/06) 11 USING TTL TO CONTROL NETWORK T RAFFIC IN BROADCAST DOMAINS In the Endura network, TTL is used to set the maximum amount of router hops that a packet is allowed to propagate through the network before the packet is discarded.
12 C1640M-B (3/06) ENDURA B BLOCK The Endura B Block generally determines the bandwidth requirements for the network. The B Block is functionally responsible for decoding and displaying the video streams, as well as providing the control and configuration of all Endura components.
C1640M-B (3/06) 13 CALCULATING BANDWIDTH AND STORAGE REQUIREMENTS Y ou must ensure that the B and C blocks are able to handle the worse-case bandwidth (B WC ) requirements. The following examples describe how to calculate the worse-case bandwidth based on the playback video stream.
14 C1640M-B (3/06) NTSC Frame Rates This section describes the National T elevision System Committee (NTSC) frame rates at high, medium, and low resolution with a dual stream NET5301T encoder . Y ou can select 6, 10, 15, and 30 IPS across all resolutions (CIF , 2CIF , and 4CIF) for each camera.

22 C1640M-B (3/06) ENDURA CORE BLOCK The Core Block is functionally responsible for Network layer 3 tasks, discovery , authentication, and security , and interconnects the A and B blocks (refer to Figure 5). The Core Block is summarized as follows: • There is only one Core Block for each Endura network.
C1640M-B (3/06) 23 ENDURA C BLOCK Figure 7 illustrates how the A, B, Core, and C Blocks concept is implemented to form a complete Endura network. The Endura network is scaled by replicating the A and B Blocks to accommodate the video input and performance requirements for the network application.
24 C1640M-B (3/06) EXAMPLES OF ENDURA NETWORK DESIGNS This section describes various Endura network configurations that are scalable and allow you to structure the network for the current as well as future application requirements.
C1640M-B (3/06) 25 MANAGED NETWORK CONFIGURATION The managed Endura network supports viewing of live and playback video, recording, and security . As shown in Figure 9, a managed Endura network includes the full assortment of Endura components: NET5301T s, NET5301Rs, WS5050s, VCD5000s, NVR5100s, the SM5000, and switches.
26 C1640M-B (3/06) Connecting the NVR5100 and SEB5000s The SEB5000 storage expansion box can be connected to the NVR5100 in one of two ways: • A patch cable is used to connect a single SEB5000 directly to an NVR5100 (refer to Figure 10 ). The NVR5100 and SEB5000 Ethernet port is autosensing.
C1640M-B (3/06) 27 Appendix A: Endura Network Configuration Example This section provides an example of how to confi gure an HP 5300 series chassis switch for an Endura Network. The information is this section is only an example of how to configure an HP 5300 series chassis switch.

C1640M-B (3/06) 29 e. Enter ip pim to enable PIM on VLAN 3. f. Enter ip helper -address 10.3.0.10 to specify where to forward DHCP requests. (In this example, the SM5000 is providing DHCP service for the Endura network.) 7. Enter exit to exit the VLAN configuration mode.
30 C1640M-B (3/06) f. Enter ip helper -address 10.3.0.10 to specify where to forward DHCP requests. (In this example, the SM5000 is providing DHCP service for the Endura network. 6. Enter exit to exit the VLAN configuration mode. 7. Enter write memory to save your configuration.
C1640M-B (3/06) 31 Appendix B: W AN Configuration Example This appendix provides a sample configuration for multicasting over a generic routing encapsulation (GRE) tunnel as an example of how to configure an Endura network using W AN connectivity.
32 C1640M-B (3/06) CITY A ROUTER (R102) CONFIGURATION FILE r102# version 12.2 ! hostname r102 ! ip subnet-zero no ip domain-lookup !--- It stops IP domain lookup, which improves the show command response time. ! ip multicast-routing !--- Enables IP multicast routing.
C1640M-B (3/06) 33 CITY B ROUTER (R104) CONFIGURATION FILE r104# version 12.2 ! hostname r104 ! ip subnet-zero no ip domain-lookup ! !--- It stops IP domain lookup, which improves the show command response time. ! ip multicast-routing ! !--- Enables IP multicast routing.
34 C1640M-B (3/06) V ERIFYING THE CONFIGURATION Complete the following steps to verify your configuration: 1. Use the show ip igmp groups command to verify that the receiver has sent its IGMP join membership request for group 239.
C1640M-B (3/06) 35 3. Use the show ip mroute group-address command to verify that R104 has the (*,239.1.1.20) and (10.1.1.1, 239.1.1.20) entries while it is forwarding multicast packets for group 239.1.1.20 sourced from 10.1.1.1, as shown below . r104# show ip mroute 239.
36 C1640M-B (3/06) T ROUBLESHOOTING If your multicast over GRE tunnel is not working, one of the following could be the cause: • T unnel not UP/UP: The tunnel source and destination do not match on each end of the tunnel. For example, if the tunnel destination on R102 was changed to the IP address 10.
