Cisco Media Services Proxy - Cisco Catalyst 4500 series Administration Manual

Chapter 1 Product Overview
Catalyst 4500 series switch also supports a Built-in Traffic Simulator using Cisco IOS IP SLAs video
operations to generate synthetic traffic for a variety of video applications, such as Telepresence, IPTV
and IP video surveillance camera. You can use the simulator tool:
•
•
The traffic simulator includes a sophisticated scheduler that allows the user to run several tests
simultaneously or periodically and over extended time periods. (Supported only on switches running the
Enterprise Services feature set.)
For information on configuring this feature, see the Configuring Cisco IOS IP SLAs Video Operations

Cisco Media Services Proxy

The Media Services Proxy (MSP) feature identifies various media end points in the network
automatically and renders appropriate media services. It acts as a layer that connects appropriate devices
with their respective network services automatically.
MSP follows a network-centric model, where the access switches and routers learn information about
devices and flow by using mechanisms such as Cisco Discovery Protocol (formerly known as CDP) and
DHCP, or by snooping on key protocol packets such as the Session Initiation Protocol (SIP) and H.323.
Modifications to the endpoints are not required to achieve the information learning. After the
information is gleaned, MSP provides appropriate services to the network devices.
Following are the benefits of MSP:
•Automatic identification of devices and flow in the network.
•Application of appropriate services to the endpoints.
•Configuration control for the administrator, thereby reducing the manual configuration and
management of services. For example, configuring the Resource Reservation Protocol (RSVP) in the
network for video applications requiring guaranteed bandwidth.

Cisco Medianet AutoQoS
Cisco Medianet AutoQoS provides a default configuration to ease the process of enabling QoS on
switches. This process can be difficult given the functional/behavioral differences in QoS across
different platforms. This functionality extend AutoQoS functionality for the Catalyst 4500 to support
video traffic as well as other kinds of traffic.

performance issues.
The system cannot scale to greater than 512 SIP flows with MSP and Flow Metadata enabled.
