摘要： An example computing device is configured to receive, from a customer device, an indication of a plurality of resources and an indication of a plurality of customer services, each of the plurality of customer services being associated with a corresponding at least one requirement and a corresponding at least one constraint. The computing device is configured to automatically determine, for each requirement and each constraint, whether the requirement or the constraint can only be satisfied by a particular resource of the plurality of resources, and allocate, based on the determining, at least one resource of the plurality of resources to at least one customer service of the plurality of customer services. The example computing device is configured to provide, to the customer device and subsequent to the determining for every requirement and for every constraint, information to enable the customer device to provision the at least one customer service.

摘要： Techniques are described for managing a plurality of requests for a change in bandwidth for a resource reservation label switched path (“LSP”) of a ring network. For example, a method may include receiving, by a network device and from an egress network device of a ring network, a resource reservation request message to establish a multipoint-to-point (MP2P) ring label switched path (LSP). The method may also include modifying, by the network device, the resource reservation request message to specify a request for a change in bandwidth for a segment from the network device to the egress network device of the MP2P ring LSP. The method may also include sending, by the network device and to a downstream network device along the MP2P ring LSP, the modified resource reservation request message.

The techniques include computing, by an ingress router, a plurality of paths for a plurality of sub-LSPs of a MP-LSP and outputting, by the ingress router, for each path of the plurality of paths, a respective resource reservation request message to establish a respective sub-LSP of the plurality of sub-LSPs, each respective resource reservation request message including an indication of an explicit route, a tunnel identifier indicating the MP-LSP, an identifier for the respective sub-LSP, an indication of a per-hop bandwidth constraint that corresponds to a respective incoming per-hop bandwidth constraint of the plurality of incoming per-hop bandwidth constraints, and one or more instructions to modify the indication of the per-hop bandwidth constraint.

摘要： Techniques are described that allow fast path delivery of content from content data networks directly to metro transport networks so as to bypass Internet service provider (ISP) networks. The metro transport network is positioned between subscriber devices and an Internet service provider network that authenticates the subscriber devices and allocates respective layer three (L3) addresses from an Internet Protocol (IP) network address prefix assigned to the Internet service provider network. Routes within the metro transport network, including an access router, ISP-facing provider edge routers and one or more peering routers, establish an EVPN within the metro transport network. The access router outputs, within the EVPN and to the peering router, an EVPN route advertisement that advertises network address reachability information of the subscriber devices (e.g., the IP network address prefix or MAC/IP address of the subscriber devices) on behalf of the Internet service provider network.

摘要： Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises a bidirectional, multipoint-to-point (MP2P) LSP for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP. Separate protection paths, bypass LSPs, detours or loop-free alternatives need not be signaled.

摘要： A method performed by a network device may include assembling a multiprotocol label switching (MPLS) echo request, the echo request including an instruction for a transit node to forward the echo request via a bypass path associated with the transit node, and an instruction for an egress node to send an echo reply indicating that the echo request was received on the bypass path. The method may also include sending the MPLS echo request over a functioning label switched path (LSP).

摘要： Techniques are described that enable MAC (L2) address authentication within an L2 switching network, such as a metro transport network. Moreover, when used in an EVPN, the techniques provide fine grain policy control over the L2 switching network so as to enable carrier networks to specify and control topologies for transporting packet-based communications. Access routers of the EVPN communicate with a L2 network address authentication device of the metro transport network and only advertise MAC addresses into the EVPN that have been validated. Moreover, the L2 network address authentication device may distribute MAC-level policies to control topologies and MAC learning within the EVPN and provide services such as per-MAC traffic quota limits.

摘要翻译：描述了用于指定和构造多协议标签交换（MPLS）环的技术。路由器可以在MPLS环内通知成员关系，并自动建立环形标签交换路径（LSP），作为环形网络中的分组传输的MPLS环路的组成部分。在一个示例中，路由器包括被配置为建立具有多个环形LSP的MPLS环的处理器。每个环形LSP被配置为将环形网络周围的MPLS分组传送到作为相应环形LSP的出口路由器操作的不同路由器。此外，每个环形LSP包括双向多点到多点（MP2P）LSP，其中任何一个路由器都可以作为入口将数据包流量引入到环形LSP中，以传输到环形LSP的相应出口路由器。单独的保护路径，旁路LSP，绕道或无环路替代方案不需要用信号通知。
