摘要： An internetworking system operating over an ATM backbone. The physical internetworking devices within the system are shared to provide the internetworking functions while servicing two or more distinct and isolated user networks. This is accomplished by logically partitioning the devices into distinct sub-elements which provide all or part of the internetworking functions. These sub-elements are uniquely allocated to independent realms which are then assigned to specific user networks.

摘要： The present invention utilizes control plane signaling to dynamically configure flexible, existential ports. The ports are referred to as existential as their nature can change over time depending on the present need of the network, and because the ports are flexible and reconfigurable to a plurality of bit rates and protocols. The present invention removes the constraints of provisioning individual ports and connections, such as from a network management system, and integrates the concept of flexible ports with signaling and control plane methods utilized for routing in modern networks. Advantageously, the present invention extends service providers' investments in equipment, and reduces operating expenses in providing systems that are able to dynamically deal with various network configurations and with low touch by automatically performing provisioning. The methods and systems of the present invention can be extended to other networks utilizing flexible ports, such as wireless radios and the like.

摘要： The present disclosure relates to carrying synchronization through Ethernet, Optical Transport Network (OTN), and other asynchronous protocols. In one exemplary embodiment, timing markers or symbols are used in packets to enable a downstream device to recover timing based upon a time differential between markers or symbols. Advantageously, enabling Ethernet, OTN, etc. to carry synchronous information will de-risk switching from SONET/SDH to Ethernet and/or OTN for service providers. The present disclosure also includes frame decomposition scheme of the Ethernet stream. Ethernet packets are broken into fixed bandwidth and excess bandwidth. The fixed bandwidth is subdivided into fixed (negotiated) flits, with each flit corresponding to a specific user or combination of users like a private tunnel. This offers service providers a method to provide deterministic and more secure bandwidth over Ethernet to multiple clients.
摘要翻译：本公开涉及通过以太网，光传送网（OTN）和其他异步协议携带同步。在一个示例性实施例中，在分组中使用定时标记或符号，以使得下游设备能够基于标记或符号之间的时间差来恢复定时。有利地，使能以太网，OTN等携带同步信息可以降低从SONET / SDH向服务提供商转换到以太网和/或OTN的风险。本公开还包括以太网流的帧分解方案。以太网数据包分为固定带宽和超宽带。固定带宽被细分为固定（协商）飞行，每个飞行对应于特定用户或用户组合，如私有隧道。这为服务提供商提供了一种通过以太网向多个客户端提供确定性和更安全带宽的方法。

摘要： The present invention provides methods and systems to remove the dependence on the IP layer (OSI layer three) in Video-on-Demand (VoD) transport networks. The present invention replaces the IP layer with Ethernet layer two addressing and even layer one, allowing connectivity in access/aggregation networks without IP layer three capabilities. The present invention enables STBs to communicate with VoD controllers, servers, and the like at layer two and/or layer one, eliminating the need for layer three routing capabilities in access/aggregation networks.

摘要： Network elements in IMS or other SIP systems are configured to pre-authenticate SIP requests either as proxy or by snooping. One or more of these network elements are pre-loaded with a local database copy of the user profiles as typically contained in the HSS inside of the IMS control structures. A master database, such as the one typically contained in the HSS, is distributed to all network elements using database distribution methods. Advantageously, pre-authentication solves bottleneck issues in the SIP mechanism by allowing an end user device to use fully authenticated SIP requests. This prevents the requirement to perform authentication, authorization, and accounting (AAA) all the way back to the core IMS network, alleviating lag and scaling issues. Additionally, network elements including can become aware of the services requested through SIP requests, and track these requests for optimization. Specifically, resources requested based upon SIP requests can be cached.

摘要： The present invention reserves special Ethernet timing packets to mark timing within Ethernet and OTN, and secondarily creates frames within the Ethernet stream through the timing marker packets. The result is standard Ethernet with timing capability that can be transported over standard Ethernet links and/or within OTN. This timing capability can be utilized to carry synchronization over asynchronous Ethernet and OTN streams. Advantageously, enabling Ethernet and OTN to carry synchronous information will de-risk switching from SONET/SDH to Ethernet and/or OTN for service providers. The present invention also includes frame decomposition of the Ethernet stream. Ethernet packets are broken into fixed bandwidth and excess bandwidth. The fixed bandwidth is subdivided into fixed (negotiated) flits, with each flit corresponding to a specific user or combination of users like a private tunnel. This offers service providers a method to provide deterministic and more secure bandwidth over Ethernet to multiple clients.
