You can set up your direct network connection to use an end-to-end virtual circuit from your premises.
The type of connection and bandwidth you provision from your site (such as a colocation facility,
headquarters, or branch office) to the data center in which vCloud Air is located depends on the capabilities
and service catalog from the network service provider you choose to provide the connectivity. For example,
you might choose the following technologies to implement your private WAN connection:
n
Multiprotocol Label Switching (MPLS)
n
Virtual Private LAN Service (VPLS)
For information about the connection options supported by Direct Connect for vCloud Air, see the question
“What deployment architectures are available?” in the Direct Connect FAQ.
Your network service provider (NSP) or telecommunications partner manages this connection. The
connection bridges your customer premises to your NSP’s terminating switch in the data center where
vCloud Air is located. Your NSP is responsible for patching the connection to a port on the vCloud Air
switch in the data center Meet Me Room (MMR) or to the carrier termination device, such as the main
distribution frame (MDF) for the data center.
Figure 5‑2. Areas of Responsibility for Direct Connect with Cross Connect
Cross Connections from Co-located Infrastructure
You can set up your direct network connection to use an intra data center cross connect. Cross connect
provides directly connected network circuits between your existing pod in the data center and the
vCloud Air service in the same facility. Using an intra data center cross connect allows you to connect two
physically isolated organizations within the data canter; specifically, your customer cage and the vCloud Air
infrastructure.
VMware provides one or more access ports for your cage in the data center where you access your
vCloud Air service. Cross connect is a point-to-point connection that does not use your network service
provider's equipment to route traffic.
Direct Connect for Network Exchange
VMware provides the connection option Direct Connect for Network Exchange.
VMware has partnered with specific NSPs to provide Direct Connect for Network Exchange. VMware and
select NSPs offer joint connectivity to bring fast, dedicated, right-sized connectivity to vCloud Air and
Horizon Air customers from anywhere on the NSPs' global MPLS networks.
