A Routing Key may be configured statically using an implementation dependent management interface, or dynamically using the M3UA Routing Key registration procedure. Maps gsm a interface emulatorgsm a interface emulation gl. The paper shows that cross traffic, especially bursty cross traffic such as ss7 signaling traffic, could indeed significantly deteriorate the sctp failover performance.

In such a case, the SG could be addressable with a Point Code in each network appearance, and represents a set of nodes in the IP domain into each SS7 network.

M3UA reports the status of an AS. Distribution of this memo is unlimited. An example scenario is where an SG appears as an element in multiple separate national SS7 networks and the same Signaling Point Code value m3uaa be reused in different networks.

However, in the context of an SG, the maximum octet block size must be followed when interworking to a SS7 network that does not support the transfer of larger information blocks to the final destination.
