MMS

The active sessions feature displays MMS streams that have a client associated with them. MMS streams that do not have a client associated with them (multicast, content management requests, and so on) are not displayed. MMS streams are displayed as follows:

❐MMS UDP streams have two connections, one for data and one for control.

❐MMS TCP streams have a single connection.

❐MMS HTTP streams have a single connection.

For additional information about streaming connections, see “About MMS Streaming Connections” on page 81.
