Quality of Service


20/47


Quality-of-Service (QoS) Overview

The goal in a QoS-enabled environment is to ensure predictabledelivery of specific traffic types, regardless of other traffic flowingthrough 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 orredundancy

The type-of-service (ToS) byte within the IP protocol represents theprecedence or priority of an IP message (packet). The Cisco IP TransferPoint can establish ToS by any combination of the following MSUcharacteristics:

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)
