MPEG-4
Format Compression video image is much more efficient than the MPEG-2 found on DVD sold commercially. This compression format is perfectly suited for high definition broadcasts without it taking up too much space on the vector used (satellite, cable, TNT). As with the MPeg-2, The definition of the image depends on the flow used to encode.
MPLS
MPLS (Multi Protocol Label Switching) Brings to the environment IP without connecting a control that was the prerogative of technologies based on connections, such as the relay frames and ATM. Based on the packet switching Data based on a label, or "label", added to their header, this technology is flexible and versatile as a label can characterize the path, source, destination, application, service quality, etc..
First, MPLS facilitates therouting Packets of pre-configured routes, according to criteria such as, for example, low congestion, the load distribution on many highways or the need to restore a link within 60 milliseconds in case of circuit failure, etc.. Intermediate systems located in the center of the network process the information contained in the primary labels much more quickly, since the decision Routing is predetermined. The packets then move faster, resources Routers and Switches are less solicited.
A "label" MPLS can be associated with a specific application flow, which helps distinguish it from others, unlike the IP protocol, it does not differentiate between applications.
An MPLS label can be coupled to a source and / or destination, creating virtual circuits private sharing a common physical infrastructure is facilitated. Furthermore, the hierarchy of MPLS labels can build VPN requiring no change to the IP addressing of customers, while coexisting with the MPLS network that some of them could be established between their different sites.
