Abstract

By relating the service identifier to a destination attribute such as a destination address, and by making the service identifier independent of a source attribute such as a source address or a customer identifier, the method achieves reduced complexity by A method of sending information from a source to a destination by a first network element, a network, and a second network element and using a service identifier, such as a service VLAN identifier, to route the information through the network. A detector for detecting a destination attribute in information and a selector for selecting a service identifier in response to detection of the destination attribute is provided to a network element comprising a client component, a service component having A customer access port and a customer interface port, the service component has a service interface port coupled to the customer interface port and a service network port coupled to the service interface port.

Description

technical field [0001] The invention relates to a method for sending information from a source to a destination via a first network element, a network and a second network element, the method comprising the step of using a service identifier to route the information through the network. [0002] Examples of said source and said destination are subscribers, examples of said first network element and said second network element are access multiplexers, and examples of said network are Metro Ethernet. Background technique [0003] A prior art method is known from US Patent 6,618,388 B2, which figure 1 discloses a first switch (first network element) coupled to a second switch (second network element) through a virtual metropolitan area network core (network). A Virtual Metro Identifier (Service Identifier) ​​is tagged to a data packet (message) for routing the data packet through the Virtual Metro Core. The virtual metropolitan area network identifier associates the virtual m...
