Scaling provider ethernet

Carrier Ethernet OAM: An Overview and Comparison to IP OAM

“…The most recent Carrier Ethernet standard is IEEE 802.1Qay [11]. It uses the same frames as IEEE 801.ah (PBB), but it adds traffic engineering capabilities and related rapid protection against failures [12]. IEEE 802.1Qay is therefore referred to as Provider Backbone Bridging with Traffic Engineering (PBB-TE).…”

On providing metro ethernet services over transparent WDM optical rings

“…IEEE 802.1ah addressed the former problems [7] by defining two types of bridges: backbone edge bridges (BEBs) and backbone core bridges (BCBs). The former type is in charge of encapsulating/decapsulating frames from/to outside of the PBB network (PBBN).…”

“…However, the new I-Tag is a 24-bit identifier to define different service instances (up to 16 million) and may be seen as a logical service identifier. The ITags are carried within the B-Tags and are used only at the BEBs to identify service instances [7,8], which can be pointto-point (E-LINE), point-to-multipoint (E-TREE), or multipoint-to-multipoint (E-LAN).…”

ETNA's Service Layer Architecture for Automatic Provisioning of Inter-Domain Ethernet Transport Services

“…Ethernet technology was improved significantly in the last years, especially in leveraging this technology for providers and carrier grade networks [1], [2], wide area networks, and backbone infrastructure. Recent standards, in particular IEEE 802.1ad (Provider Bridges network -PB) [3], IEEE 802.1ah (Provider Backbone Bridges -PBB) [4], IEEE 802.1Qay (PBB-TE) [5], IEEE 802.1ag (Connectivity fault Management -CFM), and the maturity of the technology, make this technology a valid choice for providers infrastructure.…”

“…However, when it comes to inter carrier service provisioning, it becomes complex, and current solutions are basically manual setup and management that takes lots of time and work, and 1 The research was funded by the European Community's Seventh Framework Program [FP7/2007[FP7/ -2013 under grant agreement number 215462. are very expensive as a result. There are several proposals in the research body and from the standard organizations that are trying to cope with this issue in various ways.…”
