Wide area communications technology has been challenged to virtualize large numbers of Ethernet LAN segments. This is a consequence of a mismatch between the broadcast nature of the LAN segment and the extremely constrained connectivity implied by the p2p connections or tunnels available in the WAN environment, which have been combined to create virtual LAN segments. PBB-TE has been a practical demonstration of how filtering applied to a broadcast media can result in a connection. This article…

TLDR
This paper aims at illustrating that it can still use spanning trees in metro ethernet provided that the tree generation and VLAN-spanning-tree mapping are performed adequately and calls the solution smart spanning tree bridging (SSTB), which can be used to enhance the 802.1s MSTP.

Intelligent load balancing for shortest path bridging
TLDR
An overview of a method to enhance the load spreading algorithms used by IEEE 802.1aq Shortest Path Bridging, which provides balanced network utilization and the ability to apply subtle modifications to the distribution of the traffic matrix previously unachievable with shortest path forwarding alone.

TLDR
The design and implementation of an SPB simulator for NS-3 is presented and the results prove that the communication maintains the crucial property of SPB; congruency between multicast and unicast, and symmetry between forward and backward paths.

TLDR
A look at redundancy and loop avoidance for large layer-2 provider networks - including a discussion of the current approaches in VPLS as well as new proposals, which lead to a generic solution for redundancy in large Layer 2 provider networks.
Ethernet Data Plane Evolution for Provider Networks
TLDR
The development of data plane maintenance protocols (OAM), and scaling enhancements, initially in the form of VLANs, then VLAN stacking, and more recently complete recursion of headers have led to the ability to decouple the infrastructure data plane from traditional bridging behavior while preserving other desirable attributes.
LSOM: A Link State protocol Over MAC addresses for metropolitan backbones using Optical Ethernet switches
TLDR
Simulation results for 4-node and 9-node topologies show that LSOM can improve throughput over RPR by a factor of up to 1.7 and full freedom to choose any MAN active topology allows an effective use of the available dark fiber resources.
Alternative multiple spanning tree protocol (AMSTP) for optical Ethernet backbones
TLDR
A new protocol, the alternative multiple spanning tree protocol (AMSTP), that uses multiple source based spanning trees for backbones using Ethernet switches, that provides minimum paths and more efficient usage of optical backbone infrastructure than currently proposed protocols such as resilient packet ring and rapid spanning tree.

TLDR
This work considers the case where the cost of links is independent of the node using that link, and uses a special-purpose network sampling program to increase confidence in the correctness of this stricter protocol, and a hand-proof to verify correctness.
Reverse path forwarding of broadcast packets
TLDR
Reverse path forwarding is a practical algorithm for broadcast routing in store-and-forward packet switching computer networks which can be implemented in existing networks with less complexity than that required for the known alternatives.

TLDR
A tree is a graph with one and only one path between every two nodes, where at least one path exists between any two nodes and the length of each branch is given.
Algorithm 97: Shortest path
TLDR
The procedure was originally programmed in FORTRAN for the Control Data 160 desk-size computer and was limited to te t ra t ion because subroutine recursiveness in CONTROL Data 160 FORTRan has been held down to four levels in the interests of economy.
