CIX has announced that they will place the CIX router on Pacific Bells SMDS-Cloud by September. CIX will retain its multilateral follow-up agreement, which reduces connectivity-related transaction costs. These developments indicate that there is broad consensus on the benefits of using cloud technologies as connection mechanisms. But the major ISPs have not yet agreed on a common trade agreement for interconnection. The simultaneous existence of two very different interconnection models (multilateral and bilateral) naturally raises the question: how many types of interconnection agreements can we expect in balance? If a model agreement is reached, will it resemble the CIX (multilateral) agreement, the MFA-East (bilateral) agreement or something else? At first, AnS did not join the CIX. It created a for-profit subsidiary, ANS CO-RE, and proposed a gateway agreement that would lead to full connectivity. In essence, the bridge agreement consisted of three parts. First, determine separate foreclosure fees for commercial and R-E customers. Second, you use statistical samples of traffic from each connected network to estimate the share of R and R traffic D. Third, calculate each connected network with a weighted combination of business taxes and investment R-E, with weights from the sample. A portion of the revenue generated by the gateway agreements should be put into a pool to be used to update the NSFNET infrastructure. The proposals of the members of the ANS and the CIX had little in common.

Nevertheless, after some negotiations, it was agreed that the NDS and the members of the CIX will be linked without comparison. THE NSD did not pay the CIX fee and CIX members did not pay ANS for NSFNET services. When providing services to their customers, many Internet Service Providers (ISPs) implement service level agreements against their offerings. The first NSFNET backbone built in 1986 is a logical starting point for a debate on internet connection agreements. NSFNET was the highest level of a growing network of networks organized in three-layer hierarchy. The second level of the hierarchy consisted of mid-level networks, each composed of ten to thirty universities. Many average levels have been set up with certain means of the NSF. Any medium level connected to a nearby NSFNET node. The lower layer consisted of a local campus network connected to a central network. What distinguishes the right Internet service provider (ISP) from the bad? Whether or not they complete their Service Level Agreements (SLA). An ALS is a contract between a service provider and a subscriber that defines the level of performance expected by the service provider.
