Service Provider Networks

� Convergence� Voice� Data

� APS – Automatic Protection Switching� ~50ms

� MPLS Traffic Engineering Fast Reroute� ~50ms

� IP networks – OSPF, IS-IS� ~ 1s

� Ethernet� STP: 30-50s� RSTP

Ethernet Networks

� Spanning Tree Protocol� IEEE 802.1D�Blocking, listening, learning, forwarding�Min. 2*Forward delay = 30s

� Enhancements of STP�Portfast, Uplinkfast, Backbonefast

� Rapid STP� IEEE 802.1w�Sokkal gyorsabb

RRPP

Rapid Ring Protection Protocol

� Link Layer Protocol for Rings�Rapid topology convergence (shorter than 50 ms)

�The convergence time is independent of the number of nodes in the ring network

Basic Concepts

� Domain�Ring

– Primary ring, subrings

�Control Vlan– Major control Vlan, sub-control Vlan– RRPP packets only

�Master Node– Per RRPP ring, control node– One and only one– Sending HELLO

�Transit Node�Edge Node, Assistant Edge Node

– At intersection points

Master Node

� Primary Port�Sending HELLO

� Secondary Port�Receiving HELLO

– Complete State

– Block

�Not receiving HELLO– Failed State

– Unblock

Transit Node

� Link-UP�Primary & Secondary Port is Up�Link-Down packet in case of any failure

� Link-DOWN�Primary OR Secondary Port is Down�Preforwarding state in case of link Up – Blocked

� Preforwarding�Primary OR Secondary Port is Blocked�COMPLETE-FLUSH-FDB packet

Edge Node

� Common Port�Connected to major and sub-ring

� Edge Port�Connected to sub-ring only

� Similar States�Only for Edge Ports

RRPP

Operating Mechanism

� Polling�Hello

� Link State Change Notification�Initiator is a Transit Node

� Subring Protocol Packet Path State Detection�Edge Hello
