摘要： There is provided a method for use by a first processing unit in or to be installed in a router. The first processing unit is configured or responsible for routing (or forwarding) packets to and from other routers. There may be other such first processing units in or installed in the router. In a first step (S1), information is received at the first processing unit which requires dissemination to other routers. The information also requires processing to determine what, if any, reconfiguration of the routing (forwarding) performed by the first processing unit is required. I n a second step (S2 b) the information is forwarded in a packet to other routers as required according to the routing (forwarding) configuration for the first processing unit. In a third step (S2c) the information is forwarded to at least one other first processing unit in the router (if there are any other first processing units in the router) not already in receipt of the information. If an expedited dissemination procedure is required, the second and third steps (S2b, S2c) are performed before the processing (to determine what if any reconfiguration is required) has been performed (completed) and/or before the first processing unit has been informed of the result of such processing and/or before any reconfiguration required in the first processing unit has been requested, arranged or performed (completed).

摘要： Method and apparatus for controlling transmission of data packets in a packet-switched network. When a first end-host (A) sends an address query to a DNS system (300) for a second end-host, the DNS system responds by providing a sender key created from a destination key registered for the second end-host, if the first end-host is authorised to send packets to the second end-host. Thereby, the first end- host, if authorised, is able to get across data packets to the second end-host by attaching a sender tag (TAG) generated from the sender key, as ingress tag to each transmitted data packet. A router (302) in the network matches an ingress tag in a received packet with entries in a forwarding table and sends out the packet on an output port (X) according to a matching entry. Otherwise, the router discards the packet if no matching entry is found in the table.
摘要翻译：用于控制分组交换网络中数据分组传输的方法和装置。当第一终端主机（A）向第二终端主机的DNS系统（300）发送地址查询时，DNS系统通过提供从为第二终端主机注册的目的地密钥创建的发送者密钥进行响应，如果第一个终端主机被授权将数据包发送到第二个终端主机。因此，如果被授权，则第一终端主机能够通过将从发送方密钥生成的发送者标签（TAG）作为入口标签附加到每个发送的数据分组来跨越数据分组到达第二终端主机。网络中的路由器（302）将接收到的分组中的入口标签与转发表中的条目匹配，并根据匹配条目在输出端口（X）上发送分组。否则，如果表中没有匹配的条目，路由器将丢弃该数据包。

摘要： A method of routing packets across a packet switched network domain, the network domain comprising a multiplicity nodes each of which comprises at least one ingress interface and at least one egress interface. For each node as destination, a default branching and a detour branching are defined, each of which specifies a route from each other node to the destination node, where, for each node which is two-edge connected, the default and detour branchings do not share a common ingress interface. For a packet flow being sent from a source to a destination node, for each node operating as an intermediate node, the following steps are carried out: receiving a packet at an ingress interface, identifying an egress interface based upon the ingress interface upon which the packet is received and the packet destination, forwarding the packet via that egress interface if the connected link is available and, if the connected link is not available, forwarding the packet via an alternative egress interface associated with said detour branching if the packet was received at an ingress interface associated with said default branching or dropping the packet if the packet was received at an ingress interface associated with said detour branching.

摘要： A method of reducing congestion in an IP domain is described. This is particularly applicable to IP networks employing DiffServ architecture. Congested data flows arriving at an egress edge node of the network are identified. The total congestion represented by the congested flows is determined, and a congestion extent notification is sent from the egress edge node to its ingress edge node peer. The congestion extent notification includes information regarding the total congestion and is sent on a per-class basis. Congested core routers in the network insert DSCPs into data packets passing through them to enable the egress edge nodes to identify the affected flows. The core routers may also send congestion metric messages, designed to follow the same path as the marked packets, to inform the egress edge nodes of the extent of congestion. In an alternative method, the egress edge nodes inform their ingress peers that congestion is present, without initially identifying the extent. The ingress edge node sends a query downstream, into which is inserted a congestion metric by the core routers. This enables the egress edge nodes to determine the extent of congestion and inform the ingress edge node.

摘要： Method and apparatus for controlling the routing of data packets in an IP network (200). A DNS system (202) stores a packet admission policy configured for a first end- host (B) that dictates conditions for allowing other end- hosts to get across data packets to the first end-host or not. A routing voucher is defined which is required for routing data packets to the first end-host. The routing voucher is distributed to routers (R) in the IP network. When an address query is received at the DNS system (202) from a second end-host, the voucher is supplied to the second end-host if the configured policy allows the second end-host to convey data packets. Otherwise, the voucher is not supplied. If allowed, the second end-host will add the routing voucher to any data packets directed to the first end-host. When a valid routing voucher is present in a packet at a router (204) in the network, the packet will be forwarded to the next router in the IP network. The router will otherwise discard the packet.
