The enhancement also optimises CoreDirector as a gateway switch for high-capacity aggregation and forwarding of both Ethernet and TDM services, eliminating the need for multiple Ethernet switches and Multiservice Provisioning Platforms (MSPPs). The platform's seamless integration with ON-Center, Ciena's network and services management system, enables automated point-and-click Ethernet service provisioning and management with the ability to enforce granular service level agreements (SLAs).Click here to sign up to our daily newsletter. Perrin speculates that that's why the OME 6000 line is getting such a prominent role. Those requirements played out in the deployment for the New York Stock Exchange (NYSE), for instance. (See Ciena Sending 100GE Live.) Rather, the plan is to give the products' software similiar attributes, creating a consistency that will help them work together. The new system enables an advanced optical core network, required for supporting the adoption of high-capacity services at the edge. Additionally, the system lowers ongoing operational costs by automating end-to-end service provisioning and management, inventory and resource tracking, and dynamic power management, claim company representatives. CoreStream Agility has already been selected by MCI and the U.S. Defense Information Systems Agency (DISA) for their recently announced network builds. CoreStream Agility also includes tunable transceivers with optional G.709 and multiplexing client interfaces, next-generation integrated line amplifiers, and 10-Gigabit Ethernet (GbE) support. CoreStream Agility features are backward compatible with previous CoreStream systems. CoreStream Agility also has an ITU optics interface and is fully interoperable with CIENA's CoreDirector intelligent optical core switch for additional operational efficiency and service flexibility.

As for the all-optical whatever, looks like they've proved the point that the core director may be OEO today but it can just as easily be OO. How do they segregate the bandwidth to 12.5 Ghz without having alot of light dispersion? This is all about showing the world a leadership image. In reality, 12.5 GHz is nowhere close prime time. The jury is still out on the 25 GHz vs 40 Gbps battle (aka Nortel vs Ciena). M. Flexible concatenation involves nonstandard data frames such as an STS- 4 c or an STS-Nc in which the time slots do not occupy rigidly defined contiguous time slots. In transparent flexible concatenation, the pointer from the parent time slot is used for each of the child time slots and the concatenation identifier is set to indicate no concatenation. In this way, the concatenated data appears to be a series of conventional STS- 1 s such that pointer processing may be successfully accomplished even by a network element not capable of handling non-standard concatenations. A downstream receive framer reconstructs the original STS-Nc based on the N STS- 1 s and a concatenation table the contents of which are shared between the transmit framer and the downstream receive framer. Suite 350, Charlotte, NC, 28211, US) As the use of networks has increased over time, so has the need for more bandwidth. Fiber optic networks were developed to meet this need and transmit data (e.g., voice and data signals) at high data rates. The American-based Synchronous Optical Network (“SONET”) standard and the corresponding European equivalent standard, Synchronous Data Handling (“SDH”), are examples of two industry standards developed for the transmission of data over such fiber optic mediums. For simplicity the remaining description of optical-based networks will focus upon the SONET standard. However, those skilled in the art will recognize that the concepts as they pertain to SONET are also applicable to SDH and other data transmission protocols.

In particular, conventional SONET networks required a system administrator to set up connection routes between ports coupled to the network elements of the network. A system administrator then would program the route in each network element along with the path from an ingress point to an egress point on the network. Typically, each network element in the network would have to be manually programmed to pass information in this manner. If a failure occurs in any one of the connections, the system administrator must manually reroute the connections by reprogramming the network elements. In a SONET-based network data is transmitted as a series of multiplexed time slots or frames. For example, an OC- 3 transmission is three times the base rate of OC- 1. As seen in FIG. 1, an OC- 48 signal, when converted to corresponding electrical signals, includes 48 STS- 1 frames. Each STS- 1 frame is transmitted during a respective time slot, and comprises two components: a transport overhead and a payload. The transport overhead is provided in 9 rows of three bytes each (27 bytes total), and carries administrative information used by network elements to manage the transfer of the frame through the network. The payload, referred to as the Synchronous Payload Envelope (“SPE”), is provided in 9 rows of 87 bytes each (783 bytes total) and comprises the major portion of an STS- 1. The SPE carries payload and STS Path Overhead (“STS POH”) bytes, and may begin at any byte location within the payload envelope, as indicated by a pointer value in the overhead. Certain broadband transmission protocols (e.g., ATM), however, include relatively large payloads which do not fit within a single STS- 1. Thus, in order for these protocols to be transmitted over SONET signal, a plurality of STS- 1 s are concatenated together. Such concatenated STS- 1 are referred to as STS-Nc, and are multiplexed, switched and transported as a single unit. The SPE of an STS-Nc includes N?

I am a little surpised that Ciena is going to have an OC-768 demo. I curious to see what stage there product is at.

Still, do YOU know any other vendor with commercially shipping systems capable of 12.5GHz channel spacing.

783 bytes, which may be considered as an N?87 column?9 row structure. Only one set of STS POH is used in the STS-Nc, with the pointer always appearing in the transport overhead of the first of the N STS- 1 s that make up the STS-Nc. The SONET standard, however, requires that the STS- 1 s that make up an STS-Nc occupy specific time slots. For example, FIG. 2 illustrates 48 time slots occupied by 16 OC- 3 c s transmitted within an OC- 48 frame. In order to add a new OC- 3 c, one entire row shown in FIG. 2 must be removed or reallocated. FIG. 3 illustrates specific time slots occupied by four OC- 12 c s within an OC- 48 frame. Likewise, in order to add a new OC- 12 c, an entire row shown in FIG. 3 must be removed or reallocated. If time slots 1, 2, and 3 are dropped in the OC- 48 frame shown in FIG. 2, and populated with data for an OC- 3 c, however, they could not be switched by current SONET equipment because they are not transmitted in a sequence conforming to the concatenation protocol described above. Rather, a conventional SONET network element would need to be reconfigured to thereby rearrange the remaining time slots so that a new OC- 48 frame is created which does conform to the standard concatenation sequence. If reconfiguration is not performed, the empty time slots cause bandwidth fragmentation. Reconfiguring SONET network elements, however, requires substantial down time causing disruption in the flow of data through a network. Thus, there is a need for a network element, which can arbitrarily (flexibly) concatenate time slots associated with an OC frame which are not provided in a given “row” or sequence required by SONET. The STS-Nc payload structures are required to occupy rigidly defined contiguous timeslots within the STS-N data stream. This rigid industry standard requirement results in timeslot fragmentation and inefficient bandwidth utilization in a network where traffic is mixed with STS- 1 and STS-Nc connections.

Timeslot fragmentation occurs as connections are added and deleted. For example, if an STS- 3 c connection is added to an STS- 48, three timeslots in the STS-N must be available and those three times slots must be contiguous. If this condition does not exist, other existing connections must be re-groomed to make room for the STS- 3 c. The re-grooming process results in a traffic hit for the existing connections. If the traffic is not re-groomed, then bandwidth fragmentation occurs. Flexible concatenation doesn't rigidly require the STS-Nc to occupy contiguous timeslots. Rather, the only requirement is that the parent timeslot containing the pointer value arrives into the framer before the child timeslots containing the concatenation identifier. Flexible concatenation, therefore, does not have any issues with timeslot fragmentation. If an STS- 3 c connection is added, as long as three timeslots exists within the STS-N, it can be added without having to be re-groomed. Inefficient bandwidth utilization occurs when higher layer traffic is groomed into an STS-Nc that is larger than required. Flexible concatenation allows for a flexible size STS-Nc payload structure in an STS-N. The flexible size STS-Nc payload capability allows flexibility in the size of the concatenated payload. For example, the Gigabit Ethernet can be transported in an STS- 24 c, which results in better bandwidth utilization. In particular, it is important that the intermediate facility equipment not perform any pointer justifications (the pointer bytes are in the LOH). What ends up happening is that the intermediate facility equipment does not adjust each STS- 1 payload consistently in the non-standard STS-Nc and this will result in a corrupted payload at the onset of the first pointer justification. In flexible concatenation, the child timeslots of the STS-Nc contain the concatenation identifier in the pointer value and only the parent timeslots contain pointer values.

For example, when a Sub-Network Connection (“SNC”) utilizing flexible concatenation timeslots is established on a non-transparent facility, the SNC may not operate error free. This problem is due to the line-terminating network element in the middle of the network not forwarding the pointer bytes transparently across the network. These network elements instead perform pointer processing and regeneration only for standard concatenation timeslots and cannot perform pointer interpretation correctly for flexible concatenation. Both the foregoing general description and the following detailed description explain examples of the invention and do not, by themselves, restrict the scope of the appended claims. The accompanying drawings, which constitute a part of this specification, illustrate apparatus and methods consistent with the invention and, together with the description, help explain the principles of the invention. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the advantages of the invention. DETAILED DESCRIPTION OF THE INVENTION The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. Also, the following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims. The present invention includes methods for providing connections in a network of connected network elements. Network user 10 is connected to network 100 through network element 101, and network user 20 through network element 106. The connection between two network elements defines a span. The network elements in FIG. 1 may include multiple ingress ports and multiple egress ports.

Each ingress port or egress port is connected to a physical line that can be an optical fiber, electric cable, an infrared wireless connection, RF connection, or microwave connection. Each physical line can include multiple channels. The multiple channels can be allocated by Time Division Multiplexing, Frequency Division Multiplexing, Code Division Multiplexing, or Dense Wavelength Division Multiplexing techniques. By using a cross-connect table, a network element can switch a data stream in a channel in an ingress port to a data stream in a channel in an egress port. The network elements in FIG. 1 can be of the form of OXCs (“Optical Cross Connects”). An OXC is an optical switch with multiple ingress ports and multiple egress ports. Each ingress port or egress port can be connected to an optical fiber that may operate in a DWDM (“Dense Wavelength Division Multiplexing”) mode. An OXC can be an Optical-Electrical-Optical switch or an Optical-Optical-Optical switch. How each data stream in an ingress port is switched to a data stream in an egress port is determined by the cross-connect table. An OXC can be configured to be Fiber-Switch Capable, Lambda Switch Capable, Time-Division Multiplex Capable, or any combination thereof. Typically each network element supports both a signaling protocol and a routing protocol. The routing protocol in OSRP is responsible for discovery of neighbors and link status, reliable distribution of routing topology information and optimal route determination. The signaling protocol provides the capability of establishing, tearing down and modifying connections across a network of network elements. A sub-network connection (“SNC”) defines a grouping of one or more paths that pass through a network element in the network. A signaling and routing protocol (e.g., OSRP) is used to route, establish and maintain one or more sub-network connections in a given network element. The sub-network connections are characterized as path-based or composite.

Path-based SNCs can include one or more synchronous transport signals (STS- 1 ). A composite SNC can include multiple paths. Sub-network connections define a temporary (e.g., over a short period of time, where the connection is set-up and torn down at each call) allocation of resources in the network. SNCs are provisioned when a call is made. The routing for a SNC can be explicitly or automatically defined. Provisioning of SNCs is provided through a signaling and routing protocol (e.g., OSRP). Explicitly provisioned SNCs include user (e.g., system administrator) -defined routes. Automatically provisioned SNCs make use of a routing protocol (e.g., as implemented in routing unit 250 ) for computing an optimal route. In either case, the route information is transmitted to other network elements in the network and cross-connects associated with the routes are configured. The SNCs are said to be temporary in that, resources associated with the route (e.g., bandwidth) can be dynamically re-allocated along the path. The reconfiguration includes the clearing of the set up connection (e.g., freeing the resources at a given network element). Network resources associated with the SNCs are dynamically reconfigurable. Accordingly, the failure at a single point along the path from an ingress network element to an egress network element defining the route will not result in unused and unavailable resources. In one implementation, a user can configure one or more of the following parameters associated with a SNC including a local line on which the SNC originates, the identification (ID) of the network element on which the SNC terminates, the ID of the remote line on which the SNC terminates, a class of service, a maximum allowable delay, route setting including working and protection routes, preferred status, mesh restorability, revert configurations upon fail over and reversion timers. FIG. 2 illustrates, in detail, a network element 200 (e.g.
