Bandwidth parameters include committed information rate CIR , maximum burst size, peak bandwidth, and committed burst size. To be specific, when the bandwidth of member A does not reach the CIR, member B can use the remaining bandwidth; when the bandwidths of member A and member B do not reach the CIR but their sum exceeds the total bandwidth of the V-UNI group, member A and member B pre-empt the bandwidth based on service priorities.
In the case of the NNIs that carry Ethernet services by ports, the encapsulation type can be In this case, the NNIs that an Ethernet service traverses are exclusively occupied. The other physical ports that the Ethernet service traverses may be shared. In this case, different Ethernet services can be encapsulated into different PWs and transmitted in a tunnel to the same NNI. Therefore, the occupied NNIs are reduced and the bandwidth utilization is improved.
Therefore, the occupied VLAN resources on the transport network are reduced. The post is synchronized to: Ethernet Service Special Topics.

The ports are usually connected to a motherboard, etc. Which helps negotiate its performance. Each of these can have different speed capabilities such as mb, 1Gb, 10Gb.
Like the Cat 6a and Cat 7 cables, the Cat 7a supports speeds up to 10, Mbps, but the max bandwidth is much higher at 1, MHz. The big difference between Cat6 and Cat7 is the speed and frequency. As you may have already seen, a Cat7 cable has a max. A Cat7 cable will therefore be able to transfer data faster than a Cat6 cable. But with the decreasing cost of Cat6 cabling, there is little benefit to installing an older standard in your new office.
By the numbers Originally ratified as a standard in , Cat7 was the first Ethernet cable type to offer speeds up to 10 Gbps over up to meters of copper cabling. Cat7 cables do have stricter standards for crosstalk than Cat6, roughly comparable with Cat6A.
On Cat7 vs Cat8 comparison, transmission frequency and cabling length are also of great importance. The maximum cabling length of Cat7 network cable is m with 10 Gbps while Cat8 of 30m with 25 Gbps or 40 Gbps. Another opportunity for service providers is to evolve network resource allocation and control to be more dynamic, in order to provide on-demand provisioning of cloud services. Inter-cloud network : this network role is to interconnect cloud infrastructures together.
These cloud infrastructures may be owned by the same cloud provider or by different ones. These three network components are essential for cloud services composition and delivery.
In order to provide a real added value in support of cloud services, they must offer their network requirements to cloud service users in terms of flexibility, scalability,and on-demand resource provisioning. More importantly, advanced networking functions are necessary to ensure performance, security and availability of the various types of cloud services.
Some examples of this requirement are:. Security functions: provide on-demand security functions within the core transport network to protect and control customers traffic to cloud services.
An example is firewalling functions and intrusion detection and prevention. Performance: provide on-demand application acceleration and optimization services for cloud services. This is essential to ensure application performance because these application will be accessed remotely from customers sites to the cloud providers sites and it is well known that most of business applications were initially designed for LAN environment and are negatively impacted by the delays and packet loss of the core transport network.
