4 1. Purpose In this document are detailed the technical specifications and the basic materials to interconnect to MIX and all other relevant information considered useful to an easy startup procedure for new members as well as some information regarding the growth management. 2. How to connect to MIX An Internet Service provider can connect his backbone to the MIX peering switches through various types of connections: a. at Layer 1, colocating the Peering router with MIX using WAN circuits provided by TLC Operators already present at MIX Primary PoP or by using a Carrier available in a Datacenter where a MIX access switch is located (the updated list of available carriers at MIX primary Pop is available on MIX website); b. at Layer 1, through Campus fiber optic links owned by the ISP or other Operators and reaching MIX primary PoP; c. at Layer 2, through LAN extension circuits provided by TLC Operators already present at MIX. d. By sharing a circuit with other remote MIX members (see Pooling@MIX Service) In the a, b and c scenarios on MIX Peering LAN the following equivalence will always remain true: 1 MAC Address = 1 MIX Physical Port = 1 MIX Member With respect to Pooling@MIX scenario the following equivalence will be true: n MAC Address = 1 MIX Physical Port = n MIX Member In more detail, is possible to interconnect to MIX Switches the following network equipment: a. A router, working exclusively at Layer 3 / IP b. A Layer 2 Switch c. A Layer 3 Switch able to operate both at Layer 3 as a router and Layer 2 as an Ethernet switch Pag. 4 di 9

5 2.1. Architectural Model: WAN circuit (Layer 1 interconnection) to MIX Primary PoP Through Layer1 Circuit provided by a Carrier Within MIX Data Room many Transport Services providers are already present with their own equipment able to provide WAN circuits through SDH/xWDM equipment or dark fiber solutions. The list of the available operators is kept updated by the MIX and is available at the MIX web pages, in the section MIX Participants. Geographical connections through one of these operators can happen in two different ways: in the first scenario the ISP needs to house its peering equipment (border routers) within the MIX data center, while in the second the circuit is directly terminated on MIX peering devices. ISPs using the first solution are required to provide to the Operator which will provide the circuit all the relevant information, speed, connector type (e.g.: in case of electrical termination, specify N2, N3 or BNC termination; in case of fiber specify the type of fiber SM,MM - and the requested connector type - SC, ST -). ISPs using the second solution are required to provide to MIX all the relevant information about the circuit (copper/fiber, type of connector, etc.). The ISP must be aware that the circuit will be terminated by the Layer 1 Provider on its own equipment in the MIX data room and from there, according to the chosen solution, it will be then connected either to the rack which hosts the ISP peering equipment or directly to the MIX switches. The local patch and its maintenance and de-provisioning activity are in charge of the Layer 1 Operator : from MIX perspective, the circuit is terminated on the peering device of the ISP or directly on MIX peering LAN. Patch length depends on the distance between the rack which host the ISP peering equipment and the L1 Operator terminating equipment. The MIX technical department will notify the L1 Operator about this distance inside the MIX dataroom Through Dark Fiber Optic Connection Direct fiber interconnection can be made in the following ways: a. through deployment on ISP owned fibers b. through pairs of fiber already deployed by another carrier which tipically hosts the ISP inside its own data-centers within the Caldera Campus; All the ISPs that fall within case a must subscribe in advance the Level 1 Interconnection Services at MIX: Agreement (Ref. MIX-108e): they are automatically added to the list of the possible suppliers of access to MIX as described above, The list of the available operators is kept updated by the MIX and is available at the MIX web pages, in the Pag. 5 di 9

6 section MIX Participants. ISP peering equipment can be installed in the MIX data room or alternatively kept remote within the ISP facilities in the Caldera Campus. In case of need of media converters, they will be placed inside special racks provided by the MIX. The MIX requires rackable media converters and decided to use Allied Telesis MCR12: Available models are: MC 101 XL (ST) : multimode-fastethernet 100 Mb MC 102 XL (SC) : multimode-fastethernet 100 Mb MC 13 (ST) : multimode-ethernet 10 Mb MC 103 XL (SC) : single-mode fastethernet 100 Mb Other type of media converters can be used as long as it is rackable as the standard ones and having almost the same size. Please refer to the Annexes of the Level 1 Interconnection Services at MIX: Agreement for the technical specifications of optical boxes and fiber termination equipment inside the MIX data room Through Layer 2 geographic interconnection Many LAN extension providers are present inside the MIX dataroom. The list of such providers is publicly available at the MIX web pages, in the section MIX Participants. In this scenario ISP peering equipment can be installed in the MIX data center or kept remote, based upon the ISP preference. The ISP must be aware that the Layer 2 LAN extension circuit is terminated by the L2 Operator on its own switches and then patched through fiber or copper patches as appropriate either to the ISP peering equipment or directly to the MIX switches if the ISP peering equipment is kept remote. The local patch is part of the L2 Operator responsibility domain and under its own control and maintenance. In the MIX perspective the L2 circuit is terminate alternatively on the ISP peering equipment or up to MIX Switches. Patch length determination depends on the distance between the rack which host the ISP peering equipment and the L2 Operator terminating equipment. The MIX technical department will notify the L2 Operator or the ISP about this distance inside the MIX data room Architectural Model: Connection to MIX s satellite PoPs MIX is present in some remote datacenters (see in the section Services and Fees/MIX for ISPs/Technical Infos). Please refer to technical/commercial points of contact of those datacenters for knowing details about equipment connection and/or hosting services. The list of contact persons is available at the above web pages. Pag. 6 di 9

7 2.3. Interconnection Detail: A router directly connected to MIX Switches This solution is the one MIX recommends to all his members, following one of the Architectural Designs described above. This solution guarantees the best stability and robustness to all the Exchange Point and MIX recommends his Members to use this whenever possible and to consider the other options only in the case that there are more than valid reasons not to follow this scheme. Please refer to MIX document MIX-202 MIX Peering LAN Connection: Technical Specifications about configuration details, suggested templates tailored or the most common vendors and MIX traffic limitations Interconnection Detail: A L2 switch directly connected to MIX Switches This interconnection scenario is visible in the following picture. Also this scheme can be obtained through the Architectural Models described above. This way of interconnecting must be considered as discouraged by MIX as it has been proven it is the most dangerous and the more prone to generate instabilities and other L2 issues towards MIX switches. Troubleshooting of network issues is also much more difficult with respect to the others interconnection solutions. In case the Member wants to adopt this, the following behavior must be guaranteed: Only the traffic to/from the Peering Router must be injected on MIX peering LAN No L2 management/control protocol like STP must be active on the port connected towards MIX switches. In any case we suggest to define on the Member L2 environment a dedicated VLAn for MIX access and configure MIX port and Peeing router port as untagged in that VLAN. Please refer to MIX document MIX-202 MIX Peering LAN Connection: Technical Specifications about configuration details, suggested templates tailored or the most common vendors and MIX traffic limitations.

8 2.5. Interconnection Detail: A L3 switch directly connected to MIX Switches An hybrid equipment like a Layer 3 switch requires specific care in case it is used as MIX interconnection device. Also this option is not optimal and the Member must guarantee that: the L3 switch port facing MIX is configured as route-only or active on the switch purely at Layer 3/IP On a L3 switch is always suggested to configure the interface connected to MIX switch as untagged and belonging to a VLAN (no the default one or a port-based one) having Spanning Tree or other control protocol disabled. These precautions are very important to avoid undesired traffic on the MIX public VLAN. 3. Allocation of physical resources 3.1. Port Assignment on the MIX switches The list of available ports on the MIX switches is the following: Copper FastEthernet: 10/100 base TX RJ-45 type connectors; MMF optical GigabitEthernet: 1000 base SX z - 850nm max distance 550 m LC type connectors; SMF optical GigabitEthernet: 1000 base LX z nm max distance 10 km LC type connector; SMF optical GigabitEthernet: 1000 base LH z 1550nm max distance 70 Km LC type connector; (*) MMF optical 10 GigabitEthernet: base SR ae 850nm max distance 300 m SC and LC type connectors; SMF optical 10 GigabitEthernet: base LR ae 1310nm max distance 10 Km SC and LC type connectors; SMF optical 10 GigabitEthernet: base ER ae 1550nm max distance 40 Km SC and LC type connectors. (*) SMF optical 10 GigabitEthernet: base ZR ae 1550nm max distance 80 Km SC and LC type connectors. (*) Pag. 8 di 9

9 Only on some MIx access switches are also available: 1000Base TX Gigabit over copper (RJ-45 CAT 5E/ CAT6) Fiber Fast/Gigabit Ethernet 100/1000 base SX /LX/(LH*) with the same characteristics of the ones already listed In case the ISP requires different standards, MIX will provide a separate detailed technical analysis and economical quotation. The optics marked with (*) will be dependent on the requesting ISP Rack Space assignment The assignment of racks hosting the ISP peering equipment - in case they are colocated within the MIX data room is made by the MIX technical staff and is based upon the following criteria: number and size of the terminating equipments, which must be notified by the ISP in advance; type and number of ports needed on the MIX switches. 4. Technical Information for Router Installation at MIX The following chapter is relevant for ISPs which will install their peering equipment inside MIX data room: MIX provides standard 19 racks, 600x600 or 600x800; The allocation of the type of rack is made depending on the equipment installed by the ISP; each rack is pre-cabled towards MIX switches through UTP Cat.5 or Cat.5E patch panels and MMF optical patch panels ( /125); each rack has redundant AC 220V power bars; pre-cabling is done through already existing optical boxes owned and maintained by MIX. The ISP has to provide in advance the following materials: power cords with Italian standards, national or Schuko plugs at least 2,5 mt. long; complete screw-bolt systems; cable stoppers and trays; for Fast Ethernet connections, one patch for each port UTP Cat 5 2mt. long, RJ-45 connector types, straight, to interconnect the peering equipment with the rack patch panel; for GigabitEthernet fiber connection, one optic patch per port, MM ( /125) with ST connectors on MIX side, 2mt. long (to interconnect the ISP peering equipment to the optical box inside the rack; for 10 GigabitEthernet connection, one optic patch per port, SM (9/125) with LC connectors on MIX side; a straight UTP additional patch if out-of-band management of the peering equipment is requested.
