Chapter 4 Configuring the CDS
Array Level Configuration
• Routers must support the bandwidths that are configured for the thin pipe mapping on the CDS.
Note The configured bandwidth for CCP on the Thin Pipe Map page must be the minimum bandwidth reserved
for the AF class. The sum of the bandwidths of all physical links configured for CCP among all sites
must be less than the bandwidth configured for the AF class reserved for CCP.
CCP is used as the protocol among Vaults and Caching Nodes in a VVI that uses HTTP, and among all
servers in a VVI that uses CCP and in all non-VVIs. The AF class is configured on each CDS server. See
the “Configuring the Servers” section on page 4-112 for more information.
As an example, Figure 4-25 shows the maximum bandwidth available for the various groups in a Virtual
Video Infrastructure (VVI) system with two super headends (SHEs) and three caching sites.
Figure 4-25 Thin Pipe Example
Note The maximum bandwidth available is dictated by the physical link, as well as by any network design
constraints placed on bandwidth availability. If a switched network has further restrictions, for example,
Super Headend 1(SHE1) to Super Headend 2 (SHE2) and Cache Site 3 share a 3 Gbps link on the route
between SHE1 and the other two sites, then another thin pipe must be configured to specify this 3-Gbps
restriction.
Table 4-28 lists the thin pipe mappings that would be configured for the different sites illustrated in
Figure 4-25.
