Pseudowire / Circuit Emulation |
Pseudowires (PW) are a way to emulate a native
service (e.g. PDH, SONET)) over a Packet Switched
Network (PSN). The pseudowire is used to re-create,
as far as possible, the properties of a single
passive wire that can carry the native service
traffic.
Circuit Emulation (CE) is a sub-set of Pseudowire
technology that is specifically aimed at making ATM
networks look like a collection of private circuits.
Typically the circuits being emulated are of the
T1/E1 type.
The AT6000 and AF6000 devices are a family that provides complete pseudowire protocol coverage including
SAToP, CESoPSN, MEF-8, CEP, ATM pseudowires (PW),
PPP PW, HDLC PW, Ethernet PW. Thalassa also provides
the ability to handle concatenated ATM streams for
ATM switch/aggregation and dedicated ATM pseudowire.
Many legacy protocols: DS0, DS1, E1, DS3, E3, SONET/SDH,
ATM, IMA, HDLC, PPP, FR, MLPPP, Ethernet may be
tunneled concurrently within the supported PW
connections over PSN networks. Thalassa can connect
to a wide range of PSN networks including IPv4,
IPv6, MPLS, and Ethernet.
