Quality of Service


Quality-of-Service (QoS) Overview

The goal in a QoS-enabled environment is to ensure predictable delivery of specific traffic types, regardless of other traffic flowing through the network at any given time.

QoS in Legacy SS7 Network:• Priority levels determined by SS7 service endpoints• During congestion, MSUs dropped based on 2-3 priority levels• Links are added for additional bandwidth and redundancy

Opportunity to Improve QoS in SS7oIP Networks:• Combination of traffic types are increasing as new services introduced• IP network is QoS capable• Transfer points should determine QoS• Additional SCTP (logical links) do not provide additional bandwidth or redundancy

IP CoreNetworkSS7/MTP SIGTRAN/IP

Core Router

The type-of-service (ToS) byte within the IP protocol represents the precedence or priority of an IP message (packet). The Cisco IP Transfer Point can establish ToS by any combination of the following MSU characteristics:

• Input link set (ex: link set from SMSC)

• Service Identifier (ex: ISUP or SCCP)

• Destination Point Code (ex: MSU destined to SMSC)

• Global Title Address (ex: TT or MSIDN of SMSC)

• M3UA/SUA Routing Key
