Resolve high-level network design

Determine any issues by looking at the current network design compared to the new network architecture. Consider the protocols to be used, specific implementations, mated-pair redundancy and link engineering, unihoming versus multihoming, and IP redundancy.

General considerations about the overall network include the following topics:

• Type of Network Change
  • “Dedicated network versus converged IP network”
  • “Replacement versus expansion”
  • Diversity (see Type of Network Change)
• Security

SIGTRAN protocols were designed to support specific paths between signaling points. The main protocols are M2PA and M3UA, each of which is built on top of the SCTP protocol. Read about the role of the protocols:

• SCTP (Stream Control Transmission Protocol)
• “M2PA (MTP2 User Peer-to-Peer Adaptation Layer) protocol”
• M3UA (MTP Level 3 User Adaptation Layer) Protocol
• “SUA (SCCP User Adaptation) protocol”

Be aware of Oracle-specific implementations or deviations and how they will impact your new network. Read about these implementations:

• Protocol deviations
  • SCTP Timers
  • SCTP (Stream Control Transmission Protocol)
  • Multihoming
  • M3UA (MTP Level 3 User Adaptation Layer) Protocol
• Overview of products
• “Scalability”
• IPGW/M3UA deployment scenarios and IPSG Deployment Scenario
• “IPGWx congestion management options”
• “IPGWx mateset”
• “Signaling Link Selection (SLS) routing”

Redundancy is achieved through linkset engineering, leveraging unihoming or multihoming, and IP network redundancy. Read about redundancy, links, linksets, and associations:

• Redundancy and link engineering
  • “Unihoming versus multihoming”
  • “Mated Signal Transfer Point redundancy”
  • “IPGWx mateset”
  • “Signaling Link Selection (SLS) routing”
• Additional Deployment Scenarios
