The gigabit network to be constructed must symmetrically guarantee a supply of the addresses designated in the expansion area with a bandwidth of at least 1 Gbit/s. The market research procedure carried out confirmed that the construction and operation of such a gigabit network in the remaining expansion area cannot be economically represented. For this reason, the client is prepared to provide the telecommunications company with a one-off, non-repayable investment grant to cover its profitability gap (so-called "profitability gap model").

Contract notice - General guideline, standard rule Open procedure (services) Procurement of an Internet uplink including provision of a DDoS mitigation solution The aim of this procurement measure is to procure an Internet uplink with a physical 2*10 Gbit/s bandwidth (port channel) with an estimated average utilization of at least 3,000 Mbit/s to maintain the redundant connection to the Internet for the state of Hesse. The contract is to follow on from the contract with Provider 2 which expires on February 28, 2025 (start: March 1, 2025). In addition, a service from the provider for attack detection and defense mechanisms, in particular for defense against "distributed denial of service" attacks, is to be used (protection of both IPv4 and IPv6 data streams against distributed denial of service attacks as well as DDoS protection at application level; hereinafter: "DDoS"). Use of this service is permanent and the costs depend on the data stream to be protected and the number of network segments and domains/IP addresses to be protected. With regard to the IP subnets to be protected for L3/L4 protection, a requirement for at least one /18 network is expected for IPv4 and a requirement for one /48 network (potentially two /48 networks) for IPv6 during the contract period. Ten subdomains/IP addresses or applications are expected to be required for L7 protection. The provider is also expected to provide consulting and support services, for example with regard to complex issues relating to the BGP protocol or the provision of IPv6 or the DDoS mitigation solution, which are directly related to the services described above. The aim is to conclude a framework agreement for the provision of an Internet uplink, in which the contractor provides an Internet connection for the state of Hesse at a fixed monthly price with a defined consumption volume, as well as for the use of a DDoS mitigation solution from the provider with a minimum term of 24 months and two automatic extensions of 12 months each (max. 48 months). The current provider 1 (plus.line) is excluded from this tendering process for reasons of reliability (requirement for two independent providers). This also applies to any subcontractors with regard to the DDoS mitigation services. The service must primarily be provided at the HZD location in Mainz. It may arise during the term of the contract that the service must be provided in the data center in Wiesbaden. If on-site services become necessary, the requirements regarding the regulations for access to the data center rooms in accordance with clauses 16 and 19 of the framework agreement apply to the contractor's employees. Technical requirements Internet uplink - Internet uplink of 2x 10 Gbit/s physical bandwidth. - The physical bandwidth of 20 Gbit/s must be fully available to the client for use in order to be able to transport peak loads (e.g. in the event of a failover) without any loss of quality. An average utilization during peak working hours of approx. 3,000 - 5,000 Mbit/s with an increasing trend can be expected. - The connection between the contractor's line termination and the Hzd connection router is via fiber optic (2x 10 Gbit/s single mode). - If the contractor has to bring their own connection technology into the HZD data center to provide the Internet uplink, the following conditions apply: - 19"-capable devices for installation in corresponding racks (without intermediate floors), if necessary, suitable installation rails must be supplied - All active devices must have redundant power supplies - All devices are operated in a cold aisle housing - Provision of 2x10 Gbit/s ports - LWL single-mode interfaces for plugging the patch cables to the HZD connection router - The house transfer point is determined by the HZD - The rack space is assigned by the HZD, access to the rack is not provided exclusively for the provider - The contractor provides a transfer network (IPv4/IPv6) for connecting the HZD connection routers - If necessary, it must be possible to transfer the Internet uplink from the Internet gateway in the Mainz data center to the Internet gateway in the To be relocated to the Wiesbaden data center. - The routing must not overlap with that of Provider 1, ideally up to a central exchange node, such as the Decix in Frankfurt. The current handover point of the Provider 1 line is in Wiesbaden. - If the contractor uses a subcontractor to provide the connection line (last mile), this must be named. The requirement of no overlap in the routing with that of Provider 1 also applies to the subcontractor. - The contractor guarantees that he will provide the offered and promised bandwidth for the entire term of the contract for the permanent use of Internet offers. Due to the client's usage profile, the full offered and promised bandwidth must be available at least on working days (Monday - Saturday) between 6:00 a.m. and 8:00 p.m. - It is expected that the contractor maintains a direct connection to one of the central exchange nodes such as Decix, Kleyrex or similar. - Both IPv4 and IPv6 traffic must be transported. The contractor guarantees that in addition to IPv4 traffic, it can also transport IPv6 traffic (dual stack) in the same quality and with the same range of functions. All other requirements can be found in the service description (file "Service description").
