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
