M2pa vs M3ua
M2PA is a sigtran layer. In another article we have discussed about the Sigtran with a detail example of m3ua. In this tutorial we will discuss about another layer m2pa. Along with m2pa , we will also discuss about the comparison with M3UA. Before starting discussion about m2pa vs m3ua , lets have an introduction about the sigtran m2pa layer.
What is m2pa ?
The full form is MTP2 peer adaptation layer. Means m2pa provides services to the MTP3 layer of SS7. But it is little different from other adaptation layers. It is for peer adaptation, while other sigtran layers (e.g m3ua, sua etc) are for user adaptation. What peer mean? For m2pa both the peer have same functionality, While in user adaptation, one peer is an SG. M2pa provides functionality to the MTP3 layer as MTP2 does. Only difference is that MTP2 uses TDM links while m2pa uses SCTP/IP protocols. Primitives between MTP3 and m2pa are same as between MTP2 and MTP3.
M2PA vs M3UA :
After having introduction about M2PA, now we will discuss some differences between m2pa and m3ua.
- The user of m2pa is MTP3 , while user of M3UA is SCCP.
- M2PA can connect to SGs , but m3ua can not connected two SGs.
- In M3ua, the logical entity and AS or application server, having point code, while in m2pa , there is no point code configure.
- M2pA implements same messages as MTP2 does , while m3ua, have sigtran messages.
- M2PA is a data link layer , while m3ua is an example of network layer. if we see as per OSI model.
- M3UA layer, may send the message to a remotely located application via SG. While m2pa sends messages to a directly connected node.
Above test cover details about the m2pa va m3ua.
