Thiago,
264 is used for
the BGMP
Description:
265 is X-Bone
CTL
The X-Bone is a system for
the automated deployment, management, coodination, and monitoring of IP overlay
networks. Its core is composed of Overlay Managers (OM) which deploy and
coordinate the overlay itself, and Resource Daemons (RD), which coordinate the
resources of individual network components. It also includes support for a
graphical user interface (GUI) and a more direct API (shown in the figure
below).
The GUI/API
requests the overlay, and monitors its progress. The OM advertizes an invitation
to create a new overlay, then configures the components, and monitors the
result. The Resource Daemon coordinates resource use on the individual
components, and translates generic configuration into machine-specific form.
TCP/SSL is
used for secure configuration to take advantage of TCP's reliable channel, and
reduce the number of different security schemes required in X-Bone [14]. X-Bone uses a
web-based GUI for user request of an overlay deployment. Web browsers already
support SSL, so the user's request is secure on the path to the OM. For
simplicity, we use the same mechanism between the OMs and RDs. Alternate
schemes, such as PGP, would require multiple mechanisms within the OM, and
different protocols between different pairs of components.
This
architecture utilizes a single, well-known multicast channel for invitation
announcements, and separate reliable channels for configuration and monitoring.
It is based on the multicast announcements in M-Bone teleconferencing; in fact,
X-Bone effects an overlay as if it were a teleconference among its OM and the
RDs of its router and host components.
