BRIDGE / SWITCH
A bridge is a LAN interconnection device which operates at the data link layer (layer 2)
A Switch is a Multi-Port Bridge.
Divide LAN into segments
ETHERNET FRAME
Destination address S O F Source address Length/ Type FCS 802.2 header and data Preamble Separates Between frames • MAC Address • 48 bits • Worldwide unique • Assigned at manufacturing Frame Checksum Sequence (CRC)FDB- FORWARDING DATABASE
A Switch separates the sections by Learning and Filtering
Flooding - Transmits (floods) the frame on all switch interfaces (except the sending port itself)
Forwarding - Sends the frame toward its destination
Aging - Time that an entry remains in the FDB

FDB QUOTA
Protection from MAC address storm effect from one VPN as a result of:
Malicious users

Solution - Defines the address resources for VPN by setting the FDB quota per S-VLAN

QOS – QUALITY OF SERVICE
Different applications require different priorities to guarantee a certain level of performance
Packets are classified and marked according to the type of service
These priorities are mapped to 8 levels of QoS (CoS)
CoS levels: 0 (lowest) to 7 (Highest)
High priority traffic will have

Congestion management Scheduling:
Fair Queuing – based on statistical multiplexing to allow several data flows to fairly share the link capacity
Priority Queuing - packets belonging to one priority class of traffic are sent before all lower priority traffic to ensure timely delivery of those packets
Shaper - regulates the outgoing traffic flow to a configured bit rate by queuing excess traffic in to a smooth outburst

What is MPLS? MPLS Terms Label Structure Tunnels Types MPLS ServicesWHAT IS MPLS ?
MPLS – Multiprotocol Label Switching
Carries many kinds of traffic (IP, ATM, Ethernet etc.) Layer 2.5 – Lies between layer 2 and layer 3
Provides a connection-oriented service
Packet switching network
IP ATM, FR, Ethernet, PPP IP ATM, FR, Ethernet, PPP MPLS L2 L3
MPLS MOTIVATION
MPLS LSP – Label Switched Path LSP - Tunnel
Tunnel creation across a network
Bandwidth Allocation across the network San
Francisco
New York
LABEL SWITCHING ROUTERS
Label-Edge Router (LER) - PE
Assign Initial Label to a FEC in Ingress
Remove Label at Egress and return the original packet
Label-Switch Router (LSR) - P
Forwards MPLS packets using label-switching
Capable of forwarding native IP/ETH packets
Executes one or more IP routing protocols
San Francisco New York LSP LER LSR LSR LER
MPLS – TECHNICAL SIGNIFICANCES
TE – Traffic Engineering
Service Provider (SP) can guarantee QoS
VPN - Provides Layer 2 Virtual Private Network
When traffic traverse the network it can have the following encapsulation:
Label Header
PPP Header Layer 3 Header
PPP Header (Packet over SONET/SDH)
Frame Relay Label Header Layer 3 Header
MPLS LABEL STRUCTURE
Label (20bits)
Carries the actual value of the label 2^20=1M entries in a routing table Exp (3bits):Experimental bits
Used for Priority or QoS
S (1bits):Bottom of Stack flag
Can stack multiple labels TTL (8bits):Time to Live
Counter for Loop prevention
MPLS CONTROL PLANE VS. DATA PLANE
Control Plane
Path (Tunnel) Selection
Connection-Oriented Vs. Connection-Less
Label Distribution Methods
Determine labels to nodes by management Distribute label by signaling RSVP-TE/LDP
Data/Forwarding Plane
FEC – Forwarding Equivalency Class Looking up a label in the table
MPLS LABELS
MPLS Label VPN ID (Label) Original packet (e.g. Ethernet)VC Label MAC Header Data
Tunnel Label
MAC Header
Link layer Address, Can be:
(1) Ethernet
(2) PPP
(3) Frame Relay
In Port Out Port
LABEL SWITCHING
MPLS is connection-oriented protocol
Provisioning labels to tunnels – done by Signaling/NMS Data packets can be transferred over the tunnel
LABELS
Tunnel Label – the outer MPLS label – represents the tunnel to
which the packet is mapped to
VC Label – the inner MPLS label - which represents the pseudo
wire (PW) to which the packet belongs, serves as an edge-to-edge pseudo wire (PWE3), it allows aggregating multiple services into a single tunnel

Source PE P Dest PE

TUNNEL TYPES
P2P tunnel - originates at the source PE, traverses through Transit Ps, and terminates at the destination PE
P2MP Tunnel - originates at the source PE and terminates at multiple destination PEs.
It is a tree-and-branch structure, where packet replication occurs at branching points along the tree
PE 1 P 1 PE 2 PE 4 CE CE PE 5 CE PE 3 CE
VPWS APPLICATION
VPWS - Virtual Private Wire Service P2P connectivity over MPLS
Pseudo-Wire (PW) - shares the same tunnel
VPLS APPLICATION
VPLS - Virtual Private LAN Service Multipoint connectivity over MPLS
Fully-meshed LSP tunnels are needed
VPLS ISSUES
Fully Meshed Architecture
A core architecture of 10 nodes, requires 90 unidirectional tunnels A network of 60 nodes requires 3540 unidirectional tunnels
(n2 – n tunnels)
Each unknown packet has to go through n-1 pseudo-wires
Solutions
Use Advanced Ethernet Package to scale Ethernet domains beyond standard Ethernet, and keep MPLS core network manageable
Use H-VPLS (Hierarchical VPLS) to scale the MPLS network
H-VPLS
Eliminates the need for full mesh to include spokes
Reduces signaling overhead (fewer VC-LSPs)
Simplifies discovery (a spoke is only aware of upstream PE)
Scalable inter-metro VPLS using SHG (Split Horizon Group)

LCT-APT LICENSING
Each LCT requires a license to activate it
Licenses are controlled from the EMS
EMS-APT maintains an LCT license bank, each LCT
activation withdraws one license from the bank
After installing the LCT, user should connect the LCT
host to the EMS. EMS checks the LCT license in the
bank and enables the operation
The LCT license is bound with the LCT host ID and
activated by EMS-APT
A temporary license (90 days) is provided to allow
using the LCT when there is no connection to the
EMS-APT

Field Explanation
Technology Layer
Technology layer of the link. Read only according to the port type
Media Type Media type of the selected ports: Electrical, Fiber, or
Virtual. (Read only)
Media Subtype Selection of media subtypes from the list, according to
the media type. You can also enter your own text.
Length (km/mile)
The length of the link in kilometers or miles
Protection Type of link protection, for example, MS-SPRing, MS,
external protection, or unprotected. If external protection is used, specify the type.
SRLG (Ducts) Shared Risk Link Group. Scrollable entry fields allow
you to specify the shared resources for the link.

Field Explanation
Assigned Cost (1-1000)
Enter a value for the cost based on your local
evaluations of cost on a nondenominational scale of 1-1000. A low number indicates a less expensive link..
Quality

– critical or major alarm
Orange
– minor alarm
Yellow
– warning
Green
– clear (no alarms)
Color-coding for non-operational links:
Light blue
– the link is connected and not uploaded
(an intermediate state)
Dark blue
– the link is being uploaded
INTERNAL LINKS
Internal link – A link between two ports of one

LightSoft preference settings define how trails, tunnels, and Ethernet services are created in LightSoft
Allows to configure system settings for network-wide features such as general TE, CoS, CAC, and EXP mapping preferences
System preferences can only be set by a system administrator and are applied to all server clients

The System Preferences window CoS workspace is used to configure default CoS values for new PEs created in the MPLS Layer
QUALITY OF SERVICE
Priority:
Booking factor - Overbooking ratio
allowed to tunnels per CoS on this network.
1.0: Tunnel BW can reach up to 100% of MoT BW (no overbooking)
2.0: Tunnel BW can reach up to 200% of MoT BW
High Strict priority, committed traffic with low latency.
PIR=CIR= Tunnel BW
Low Fair queuing, have EIR and can accept drops when applicable,
QUALITY OF SERVICE
A CoS can be set as a BE (Best Effort) CoS, which can be
associated with zero BW tunnels in order to save bandwidth over the network for BE CoS services aggregation
BE Protection :
Enabled The Bypass tunnel protects all assigned tunnels regardless of their bandwidth
Disabled The bandwidth sum of the tunnels
protected is limited by the Bypass tunnel bandwidth
