LINX is able to offer members the ability to connect to the LON1 exchange using a private VLAN (pVLAN). Using a pVLAN service allows the member port to be split into different sub interfaces. Members may choose to use pVLAN so they can access services directly from other members also connected to the exchange. The port can still be used for peering.
Greater Port Utilisation
Peering fosters a spirit of community, LINX members cooperate and trust each other with their network traffic, and as result everyone benefits, from fast, robust, low cost and efficient internet services. This spirit of cooperation extends beyond peering, and many members also access each other’s services using direct interconnects. In order to consume each other’s services members, have to be aware of each other’s capabilities, and have to build a business case to justify the cost of the interconnect. Usually this limits the member cooperation for other services to members who are based in the same datacenter and have good community knowledge. A member will connect to a service providing member using a cross connect provided by the data centre.
By creating a private VLAN over the LINX port the member can connect to the service providing member, using the same port as their peering port. They can connect to several different service providing members using the same port reducing the number of cross connects needed and hence costs. Connecting to multiple services over the same port also frees up ports on line cards thus providing improved ROI on infrastructure costs.
Increased Value
In addition, members now have access to service providing members at any LINX location as they are able to use the LINX network infrastructure to reach these members. Access to more service providers gives the member more choice of supplier and the speed with which pVLAN services can be provisioned and deprovisioned allows members to take the services for short periods, giving members the ability to test different suppliers, or access a service for a short term to support specific projects.
Reduced infrastructure costs lowers the entry cost for members who are consuming each others services. This benefits both members. Service providing members see increased consumption with no increase in technical overhead and members consuming the services are able to do so at lower volumes and therefore have more choice and flexibility when building their customer solutiuons.
LINX Private VLAN ServicePrivate VLAN, also known as port isolation, is a technique in computer networking where a VLAN contains switch ports that are restricted such that they can only communicate with a given “uplink”
Summary of Benefits
The Private VLAN service offers LINX members the following benefits:• Increased utlisation on port• Reduced number of cross connects• Access to additional services• Use of the LINX network• Fewer ports used on line card• Increased choice of supplier• Additional services easily accessed for short periods.

LINX pVLANService in Detail
Technical considerations of the LINX pVLAN Service
The member will present individual member Layer2 ports as 802.1q tagged VLAN interfaces. These interfaces will be added into the peering LAN layer2 domain and as such become part of the broadcast domain. The interconnect ports can be either 1 GE 10GE or 100GE ports or multiples thereof.
LINX expect that the members Layer2 connection is limited to the contracted bandwidth as specified during the order process.
More Information
Joining LINX and exchanging traffic could not be easier. We have a simple sign up process with an annual membership fee for all members. LINX membership enables networks to take ports on any of its six LANs.
In London, LINX’s dual LAN policy provides members with the option of added resiliency through taking ports on both LON1 and LON2. These LANs span a 64km metro area serviced by multiple PoPs from several carrier neutral datacentre operators.

Why LINX?
LINX is a member owned organisation. The ethos of LINX is to provide increasing value to its members, by continually reducing prices and by improving the value members can derive from its services. This is demonstrated by the reduction of port prices year on year and the addition of new services such as pVLAN.

Sub Interface Port Sizes
Sub interfaces can be provisioned in the following sizes listed below:
• 100M • 500M • 2GE • 5GE• 200M • 1GE • 3GE • 10GE• 250M • 1.5GE • 4GE
pVLAN rate-limiting configurations
LINX applies per pVLAN rate-limiting configurations at the LINX edge router. These are setup to 10% above the committed rate with a burst size limit of the equivalent number of bytes transferred over a period of 1 second at the committed rate.
Why London?
Based in London gives LINX several advantages, the large number of data centres available gives potential new members choice and generates healthy competition and keen pricing. LINX has multiple presence in all of the major London data centre locations. The pVLAN services gives members access to each others services regardless of location.
