+a connection with destination networks</title><shortdesc>Destination networks, also known as Service Network Access Points
+(SNAPs) avoid the connectivity problems that are related to the access point
+being fixed for the duration of the data connection.  With the availability
+of WLAN and other data bearers, the number of access points has grown considerably.
+ With WLAN, the availability of an access point can change frequently.  A
+fixed access point in selection often leads to a poor access point choice.
+Because the network environment is now more dynamic, you can have either a
+safe but slow connection, or a fast but unreliable connection. In practice
+this means that the application is either stuck with using GPRS or the user
+must continuously change the settings to point to the WLAN access point that
+happens to be available.  A fixed access point leads to non-optimal usage
+of available connections, especially with applications that use long-lasting
+data connections.</shortdesc><prolog><metadata><keywords/></metadata></prolog><taskbody>

+should monitor the connection state by using platform services (such as Connection
+Monitor Server API) and avoid polling and keep-alives. If the application
+protocol mandates the use of timers, they should be tuned so that the control
