General
The Trinet network is based solely on Ethernet technology. The core network and Internet connections were upgraded to 10 Gbps in 2009-2010, and most recently to 100 Gbps in 2018. The remaining parts of the network use either 10 Gbps (unprotected core access) or 10+10 Gbps (protected core access) links.
The network topology is visualized in the Trinet weathermap.
Routers
Trinet uses two Juniper MX204 routers that provide IPv4 and IPv6 routing for the entire network. Each router has a dedicated 100 Gbps connection to Funet, and they are interconnected via a 100 Gbps link. Each router has a total forwarding capacity of approximately 400 Gbps.

Cabling and wall sockets at the current sites
The following table provides cabling and wall socket for each building. The amount of possible wall sockets and connected Ethernet ports varies case-by-case, depending on when the building has been built or last renovated. Please note that there might be some exceptions such as extra wall sockets. This table describes the general baseline configuration.
Every wall socket should have at least one connected port. Recently built or renovated buildings usually have wall sockets in every room but some older buildings may only have a single wall socket to be shared for the whole apartment. If your apartment has only one connected wall socket and multiple tenants, the connection must be shared.
In some apartments there might be a small apartment's own distribution panel where uplink connections can be patched to desired rooms and wall sockets. A small switch can be used if there are not enough uplink ports for each wall socket. More info can be found from our instructions.
The table also indicates single-mode fiber readiness, although fiber connections are not currently in use.

Routing and Switching Layers
Except for the routing layer (ie. Juniper MX routers), the Trinet network is fully based on Layer 2 Ethernet switching at the aggregation and access levels. Access switch connectivity to the core network is typically protected using a simple active/passive link-state scheme.
The routers use Multi-Protocol Label Switching (MPLS) as the underlay technology, along with the Label Distribution Protocol (LDP) to provide modern capabilities to protect the network in case of a link or a device failure. Currently, Trinet uses fairly traditional Virtual Private LAN Service (VPLS) overlay services to connect end-user layer-2 networks to layer-3 routing. In the future, we aim to transition to Segment Routing MPLS (SR-MPLS) as the underlay and Ethernet VPN (EVPN) for overlays and potentially extend the underlay/overlay architecture closer to the network edge.
Unicast and Multicast Routing
Border Gateway Protocol (BGP) is used for both IPv4 and IPv6 unicast and multicast routing. To reduce Internet connectivity convergence delay in the event of a link failure, Bidirectional Forwarding Detection (BFD) is utilized with IPv4 BGP to detect a link failure on a sub-second time scale. The Internal Gateway Protocol (IGP), specifically Intermediate System to Intermediate System (IS-IS), is used to establish connectivity between Trinet routers by advertising the loopbacks and the link networks. The second role for IGP is to provide BGP next-hop reachability. Otherwise BGP carries all external and internal route information.
Both Funet uplinks are typically active as they use the same BGP metric. The model is known as "hot-potato" or closest-exit routing.
Multicast routing uses Protocol Independent Multicast - Sparse-Mode (PIM-SM) and Source-Specific-Mode (PIM-SSM) along with Multicast Source Discovery Protocol (MSDP), which enables inter-domain IPv4 multicast routing.
Customer Access
Trinet uses Virtual Router Redundancy Protocol (VRRP) for customer-facing network segments. Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are used for IPv4 and IPv6 multicast, respectively. Jumbo frames are supported, with an IP Maximum Transfer Unit (MTU) of up to 9000 bytes.
User IP addresses are assigned via Dynamic Host Configuration Protocol (DHCP) for IPv4, and via Stateless Address Autoconfiguration (SLAAC) and DHCPv6 for IPv6.
Trinet's security and filtering policies are detailed in the Usage Policy.
