    The changes linked to new features in version 2.00 are listed below. XHub-VIA can be used as switch for XNet-VIA. • See section "XNet-VIA" on page 17. A command line interface allows to configure the switch.
  • Page 9: Introduction

    XNet-VIA switch XHub-VIA IP Aggregator The XHub-VIA IP Aggregator enables to have a single uplink to the Live IP fabric. It makes it possible for the XT-VIA/XS-VIA  server to support single link UHD-4K streaming in ST2110 and also very dense 1080p SLSM configurations that could surpass the native 10Gbps bandwidth of the ports on the server.

    The port speed on the XHub-VIA is configured accordingly to the port speed on the XT- VIA or XS-VIA server. If a V4X module is set to 12.5Gbps, the appropriate port on the XHub-VIA (i.e. the port connected to this V4X module) is also set to 12.5Gbps.

  • Page 27: Connecting Xhub-Vias

    • the XT servers belong to different sub-setups which are temporarily interconnected. The XHUB-VIA switches can be connected through one of the 100G QSFP ports using a fiber optics cable and QSFP adapters (QSFP-100G-SR4). In most cases, a single uplink is realized between two XHub-VIA switches. See section "Single Uplink"...
  • Page 28: Network Architectures

    XHub-VIA has only servers that are configured as Forbidden. Because there is no XNet server, they will be isolated from each other and be in standalone mode.
  • Page 29 As a result, for each uplink the total uplink bandwidth never exceeds the available 100Gbps (in both directions). In other words, the buffer of the incoming packets are not overflowing and we will never have packet drops on the XHub-VIA switch. 4. XNet-VIA...
  • Page 30 The schema below differs slightly from the schema above. The uplink connection between the XHub-VIA in the center and the XHub-VIA in the red area has 11 XT-VIAs on one side, and 10 XT-VIAs on the other side. This uplink might become the bottleneck in a scenario where each of the 11 XT-VIAs in the red area is receiving a 10G transfer from a different other XT-VIA in the network.
  • Page 31: Protection Switching

    Protection Switching About Protection Switching Protection switching (PRS) consist in linking 2 XHub-VIA switches with two 100G uplinks, namely a 'primary' and 'secondary' uplink. By default, the primary uplink (or 'working path') is the link used to transfer the data. If this link breaks, the secondary uplink (or 'protection path') will be used instead.

    The 14 SFP interfaces have their own IP addresses. They are configured via the Multicam configuration pages (see XT-VIA configuration manual). The QSFP interfaces of the XHub-VIA IP Aggregator do not have their own IP Address. OUTBOUND STREAM For the outbound stream, the multicast address configured in the Live IP interface will be used, together with the unicast address of the XT’s SFP interface (SFP 1-C, 1-D, ...).
